New distributional records of Southern Ocean Isopoda based on vouchers from the Italian National Antarctic Museum (MNA, Section of Genoa)
The order Isopoda Latreille, 1816 consists of a large number of species occurring in terrestrial, marine, and freshwater environments. In the Southern Ocean (SO), this group is among the most speciose ones and occurs at all depths. Isopoda biogeography, despite being studied since the first Antarctic expeditions, is still poorly known from a geographical point of view, showing large occurrence gaps for some groups in specific sectors of the SO. In this paper, we update the isopod checklists of the Ross Sea and of some peri-Antarctic areas, such as the South Orkney Islands (SOI) and the South Sandwich Islands (SSI), based on the study of museum vouchers curated by the Italian National Antarctic Museum (MNA, Section of Genoa). A total of 279 MNA samples from 15 different expeditions were studied. From this material, 41 accepted species distributed in 24 families, and 51 genera were recognized. Comparing this newly obtained information with the GBIF (Global Biodiversity Information Facility) and OBIS (Ocean Biodiversity Information System) portal, 15 species are here reported for the first time in the Ross Sea, with 5 new records in the Ross Sea Marine Protected Area. All records are new for the Terra Nova Bay area, for which a checklist of this group has never been produced before.

SOVIET ANTARCTIC EXPEDITIONS for Zooplankton (R.V. OB March-May 1956, January-March 1957;R.V.ACADEMIC KURCHATOV, October 1971-January 1972; RV DMITRY MENDELEEV;R.V.ACADEMIC IOFFE 1992).
This dataset presents data from Russian Southern Ocean Investigations. It covers the following SOVIET ANTARCTIC EXPEDITIONS: 1. R.V. Ob Cruise I-II- March-May 1956, cruise II -January-March 1957.The stations of cruise III presented in these protocols are sampled in March 1958. The aim of zooplankton studies from the Ob cruises was the investigation of its composition, abundance and quantitative distribution in Antarctic. The material was sampled with closing vertical hauls of a Juday net ( mouth opening 0,1m2,and 176 µm mesh gause) within the upper 0-500m layer. The sampled layers were usually the next: 0-10, 10-25 (or 0-25), 25-50, 50-100, 100-200 and 200-500 m. The length of lowered wire and the closing depth depended on the angle. Unfortunately a lot of samples got broken during the storms, so the obtained results are not fully complete. The samples processing included identification and counting of plankters. All largerer organisms (>3-5 mm) were enumerated in a total sample. Small organisms were counted in a subsample of ½ -1/10 of the total sample volume, according of the standard methods used at the Plankton Laboratory of the Institute of Oceanology. The sampling was fulfilled in the I cruise by Dr. M.E.Vinogradov and Dr. K.A. Brodski, in the II cruise by Dr. K V. Beklemishev and V.S. Korotkevich and in the III cruise by Dr. K.A. Brodski and A.G. Naumov. The processing of all samples was carried by N.M. Voronina. In total from the I cruise 134 samples from 34 stations are sampled and analyzed, from the II cruise 371 sample from 83 stations and from the III cruise 23 samples from 10 stations . R.V.ACADEMIC KURCHATOV, cruise 11, October 1971-January 1972. The main task of this cruise was to obtain a general characteristic of mesoplankton species composition and abundance and its changes in space and time. The samples were usually collected by vertical hauls of closing Juday type nets with mouth opening 0,1 m2 and 180 µm mesh gause. But at station 909 an oceanic modification of this net was used (JOM mouth opening 0,5 m2). The following layers were usually sampled: 0-50, 50-100, 100-200,200-300, 300-400,400-500 and 500-1000 m. In the second part of the cruise the layer 1000-1500 was additionally sampled. The length of lowered wire and the closing depth depended on the angle. The sample processing included identification and counting of Copepoda Calanioida species. . In addition within the upper 100 m all other mesoplankton groups or species and copepods nauplia were counted. All larger organisms (>3-5 mm) were enumerated in a total sample. Smaller organisms were counted totally or in a subsample of ½ -1/10 of the sample volume, according of the standard methods used at the Plankton Laboratory of the Institute of Oceanology. The sampling was carried out by Dr. N.M. Voronina, Dr. Y.A. Rudyakov, Dr. B. Vilenkin and an assistant. The treatment of samples was handled by N.M. Voronina. In total, 225 samples from 31 stations are collected and analyzed. Among them are 63 samples that were collected at station 909 during diurnal investigations, where 9 series in the depths between 0-600 m are sampled. ( NB. It seems that the absence of Neocalanus tonsus on St. 932 is a mistake). RV DMITRY MENDELEEV, cruise 43, 1989 The tasks of plankton studies in this cruise were: 1) to observe the time changes in the age composition and vertical distribution of main copepod species and 2) to obtain a general comparative characteristic of importance of different taxonomic groups in mesoplankton. The samples were collected mainly with Juday net, with a mouth opening diameter of 0,1 m2 or with JOM net, 0,5 m2 mouth opening at several stations. In both cases, the gause was 180 µm. The series of vertical hauls were done in daytime from depths from 0 to 1500 m. The surveyed layers were usually the next: 1500-1000, 1000-1500,500-200 and 25-0 m; between the last they depended on the hydrographic structure of the water. Sampling was conducted using an electronic closing system (Flint at all, 1978). It was done by Dr. A.S.Fedotov and engineer A.S. Malishev. The laboratory analyses were done by Dr. N.M. Voronina right during the cruise. They included counting and identification of organisms. Depended of plankton quantity the samples were counted totally or a subsample ½ -1/5 of it was taken. In total 65 samples from 8 stations were collected and handled. R.V.ACADEMIC IOFFE, cruise 6, 1992. The tasks of plankton studies in this cruise were: 1) the comparison of species composition in different modifications of Antarctic surface waters, 2) the observation of the dependence of vertical distribution of plankton organisms on the hydrophysical structure of the water and 3) the consideration the influence of salps on the copepod populations. The samples were collected with vertical hauls of a Juday net, with a mouth opening diameter of 0,1 m2 , and a mesh size of 180µm. The series of hauls were done in daytime from depths from 0 to 1500 m. The catched layers were usually the next: 1500-1000, 1000-1500, 500-200 and 25-0 m; between the last they depended on the hydrophysic structure of the water. Sampling was conducted using an electronic closing system (Flint at all, 1978). It was carried out by Dr. A.F.Sazhin and engineer S.N.Sedelnicov. The laboratory analyses were carried by Dr. N.M. Voronina during the cruise. They included counting and identification of organisms. Only a selected set of species were considered. They were the most abundant Antarctic copepods, euphausiids and salps. After this, all findings of subantarctic copepods were registred. Depended of plankton quantity the samples were counted totally or a subsample ½ -1/5 of it was taken. In total 65 samples from 8 stations were collected and treated.

Open-ocean environments provide few obvious barriers to the dispersal of marine organisms. Major currents and/or environmental gradients potentially impede gene flow. One system hypothesized to form an open-ocean dispersal barrier is the Antarctic Polar Front, an area characterized by marked temperature change, deep water, and the high-flow Antarctic Circumpolar current. Despite these potential isolating factors, several invertebrate species occur in both regions, including the broadcast-spawning nemertean worm Parborlasia corrugatus. To empirically test for the presence of an open-ocean dispersal barrier, we sampled P. corrugatus and other nemerteans from southern South America, Antarctica, and the sub-Antarctic islands. Diversity was assessed by analyzing mitochondrial 16S rRNA and cytochrome c oxidase subunit I sequence data with Bayesian inference and TCS haplotype network analysis. Appropriate neutrality tests were also employed. Although our results indicate a single well-mixed lineage in Antarctica and the sub-Antarctic, no evidence for recent gene flow was detected between this population and South American P. corrugatus. Thus, even though P. corrugatus can disperse over large geographical distances, physical oceanographic barriers (i.e. Antarctic Polar Front and Antarctic Circumpolar Current) between continents have likely restricted dispersal over evolutionary time. Genetic distances and haplotype network analysis between South American and Antarctic/ sub-Antarctic P. corrugatus suggest that these two populations are possibly two cryptic species.

Distributional records of Ross Sea (Antarctica) planktonic Copepoda from bibliographic data and samples curated at the Italian National Antarctic Museum (MNA)
This dataset gathers distributional data on planktonic copepods (Crustacea, Copepoda) collected in the framework of the III, V and X Expeditions of the Italian National Antarctic Program (PNRA) held in the western Ross Sea from 1987 to 1995. Sampling was conducted with BIONESS and WP2 net in 94 different sampling stations, mainly distributed in the Terra Nova Bay area, at the depth of 0-1000 meters. In terms of spatial coverage, this dataset covers 6027 distributional records that are also reported in terms of original abundance data (ind/m3) to allow a possible modelization of species distributions thanks to the availability of environmental variables that were collected together with the biological samples. The total of distributional records here reported has two different origins: 5306 are represented by bibliographic records obtained by digitizing the original data reports, whereas 721 correspond to physical museum vouchers, now curated by the Italian National Antarctic Museum (MNA, Section of Genoa). This group of museum samples comprises 8225 individual specimens, that were identified to the lowest possible taxonomic level. They belong to 4 orders, 25 families, 52 genera and 82 species, out of which 17 could be only determined at the genus level.

This dataset represents a literature study on the distribution of Benthic Hydrozoids in Antarctic and Sub-Antarctic waters. Dataset supplied in the framework of the SCAR Biogeographic Atlas of the Southern Ocean (BASO). The Biogeographic Atlas of the Southern Ocean is a collection of representative maps and syntheses on the distribution of the Southern Ocean organisms, providing a general overview of the biogeography of the Southern Ocean (s.l.) and a benchmark of current biogeographic knowledge at the end of the Census of Antarctic Marine Life. This updates the well-known and useful but largely outdated Hedgpeth 1969’s Folio on “Distribution of selected groups of marine invertebrates in waters south of 35°S latitude” in the Antarctic Map Folio Series (American Geographical Society). Antarctic benthic hydroids belong to the class Hydrozoa and are represented by members of the two hydrozoans subclasses, Hydroidolina and Trachylina. Peak diversity among hydrozoans in Antarctic benthic communities exists in the subclass Hydroidolina, represented by the orders Anthoathecata and Leptothecata, with the later being much better represented. Of 179 species considered, only two belong to Trachylina, in particular to the order Limnomedusae. The remaining 177 species are unequally distributed between Anthoathecata and Leptothecata.

The Register of Antarctic Marine Species
The objective of RAMS is to compile and manage an authoritative taxonomic list of species occurring in the Antarctic marine environment, for establishing a standard reference for marine biodiversity research, conservation and sustainable management. The taxonomic scope of RAMS covers Antarctic species from the three realms of the Southern Ocean: the sea floor (meio-, macro- and megazoobenthos; micro- and macrophytobenthos), the water column (phytoplankton, zooplankton, nekton) and the sea-ice. A series of preliminary species lists of Antarctic marine invertebrates, mostly for macrobenthic groups, were compiled by Andrew Clarke and Nadine Johnston of the British Antarctic Survey (BAS), with funding from the UK Foreign & Commonwealth Office and British Antarctic Survey. These lists have been or are being checked and updated by taxonomic experts. A series of preliminary species lists of Antarctic marine invertebrates, mostly for macrobenthic groups, were compiled by Andrew Clarke and Nadine Johnston of the British Antarctic Survey (BAS), with funding from the UK Foreign & Commonwealth Office and British Antarctic Survey. These lists have been or are being checked and updated by taxonomic experts. RAMS is managed by an Editorial Board comprising an Executive Committee and associate Taxonomic Editors. The RAMS Executive Committee plays an advising role in the development of RAMS and proposes Taxonomic Editors. It links with the SCAR-MarBIN International Steering Committee. To allow RAMS to be as exhaustive and authoritative as possible, the role of the network of Taxonomic Editors is crucial. These Taxonomic Editors are world experts on the taxonomy of their relevant taxa and are in charge of the content and quality control of data for their specific group.

Bacteria and Archaea biodiversity in Arctic terrestrial ecosystems affected by climate change in Northern Siberia
Methane emissions from aquatic and terrestrial ecosystems play a crucial role in global warming, which is particularly affecting high-latitude ecosystems. As major contributors to methane emissions in natural environments, the microbial communities involved in methane production and oxidation deserve a special attention. Microbial diversity and activity are expected to be strongly affected by the already observed (and further predicted) temperature increase in high-latitude ecosystems, eventually resulting in disrupted feedback methane emissions. The METHANOBASE project has been designed to investigate the intricate relations between microbial diversity and methane emissions in Arctic, Subarctic and Subantarctic ecosystems, under natural (baseline) conditions and in response to simulated temperature increments. We report here a small subunit ribosomal RNA (16S rRNA) analysis of lake, peatland and mineral soil ecosystems.

Antarctic Peninsula Bacterioplankton 16S rRNA gene surveys and metagenomes from Winter 2002 and Summer 2006.
Antarctic surface oceans are well-studied during summer when irradiance levels are high, sea ice is melting and primary productivity is at a maximum. Coincident with this timing, the bacterioplankton respond with significant increases in secondary productivity. Little is known about bacterioplankton in winter when darkness and sea-ice cover inhibit photoautotrophic primary production. We report here an environmental genomic and small subunit ribosomal RNA (SSU rRNA) analysis of winter and summer Antarctic Peninsula coastal seawater bacterioplankton. Intense inter-seasonal differences were reflected through shifts in community composition and functional capacities encoded in winter and summer environmental genomes with significantly higher phylogenetic and functional diversity in winter. In general, inferred metabolisms of summer bacterioplankton were characterized by chemoheterotrophy, photoheterotrophy and aerobic anoxygenic photosynthesis while the winter community included the capacity for bacterial and archaeal chemolithoautotrophy. Chemolithoautotrophic pathways were dominant in winter and were similar to those recently reported in global‘dark ocean’ mesopelagic waters. If chemolithoautotrophy is widespread in the Southern Ocean in winter, this process may be a previously unaccounted carbon sink and may help account for the unexplained anomalies in surface inorganic nitrogen content.

The Retrospective Analysis of Antarctic Tracking (Standardised) Data from the Scientific Committee on Antarctic Research
The Southern Ocean is a remote, hostile environment where conducting marine biology is challenging, so we know relatively little about this important region, which is critical as a habitat for breeding and foraging of many marine endotherms. Scientists from around the world have been tracking seals, penguins, petrels, whales and albatrosses for more than two decades to learn how they spend their time at sea. The Retrospective Analysis of Antarctic Tracking Data (RAATD), was initiated by the SCAR Expert Group on Marine Mammals (EG-BAMM) in 2010. This team has assembled tracking data shared by 38 biologists from 11 different countries to accumulate the largest animal tracking database in the world, containing information from 15 species, containing over 3,400 individual animals and almost 2.5 million at-sea locations. Analysing a dataset of this size brings its own challenges and the team is developing new and innovative statistical approaches to integrate these complex data. When complete RAATD will provide a greater understanding of fundamental ecosystem processes in the Southern Ocean, help predict the future of top predator distribution and help with spatial management planning.

In situ observations of Stygiomedusa gigantea
This dataset was provided by Dhugal Lindsay (Japan Agency for Marine-Earth Science and Technology (JAMSTEC)). The data is extracted from a paper by Mark C. Benfield (Department of Oceanography and Coastal Sciences, Louisiana State University) and William M. Graham (Dauphin Island Sea Lab and University of South Alabama). Four individuals of the large scyphozoan jellyfish Stygiomedusa gigantea were observed in the northern Gulf of Mexico over 2005 – 2009 by industrial remotely operated vehicles as part of the SERPENT Project. One of these observations included the symbiotic Bythitid fish Thalassobathia pelagica. Prior to these observations, neither S. gigantea nor T. pelagica had been observed in, or collected from the Gulf of Mexico. In order to summarize the available information on S. gigantea, we located 110 observations obtained over 110 years (1899 – 2009) representing 118 individual specimens of this species from around the world. The resulting dataset confirms that this species is cosmopolitan occurring with records from all Oceans except the Arctic. While the depth range of the four Gulf of Mexico specimens was bathypelagic, there appears to be a pattern of S. gigantea occurring in mesopelagic and epipelagic depth zones at high latitudes, particularly in the Southern Ocean and mesopelagic and bathypelagic depths at mid- and low-latitudes. This pattern may be related to the meridional vertical distribution of temperature or perhaps avoidance of light levels that could degrade porphyrin pigments. There was no evidence that this species migrates vertically. Two of the individuals in the Gulf of Mexico appeared to be actively clinging to subsea structures and we speculate that this is a consequence of its normal mode of feeding which may entail using its large oral lobes to hold on to, and trap prey.

Geomicrobiology of Antarctic Subglacial Environments - Subglacial Lake Whillans
Liquid water has been known to occur beneath the Antarctic ice sheet for more than 40 years,but only recently have these subglacial aqueous environments been recognized as microbial ecosystems that may influence biogeochemical transformations on a global scale. Here we present the first geomicrobiological description of water and surficial sediments obtained from direct sampling of a subglacial Antarctic lake. Subglacial Lake Whillans (SLW)lies beneath approximately 800m of ice on the lower portion of the Whillans Ice Stream (WIS) in West Antarctica and is part of an extensive and evolving subglacial drainage network. The water column of SLW contained metabolically active microorganisms and was derived primarily from glacial ice melt with solute sources from lithogenic weathering and a minor seawater component. Heterotrophic and autotrophic production data together with small subunit ribosomal RNA gene sequencing and biogeochemical data indicate that SLW is a chemosynthetically driven ecosystem inhabited by a diverse assemblage of bacteria and archaea. Our results confirm that aquatic environments beneath the Antarctic ice sheet support viable microbial ecosystems, corroborating previous reports suggesting that they contain globally relevant pools of carbon and microbes that can mobilize elements from the lithosphere and influence Southern Ocean geochemical and biological systems.

The bivalve Lissarca notorcadensis is one of the most abundant species in Antarctic waters and has colonised the entire Antarctic shelf and Scotia Sea Islands. Its brooding reproduction, low dispersal capabilities and epizoic lifestyle predict limited gene flow between geographically isolated populations. Relationships between specimens from seven regions in the Southern Ocean and outgroups were assessed with nuclear 28S rDNA and mitochondrial cytochrome oxidase subunit I (COI) genes. The 28S dataset indicate that while Lissarca appears to be a monophyletic genus, there is polyphyly between the Limopsidae and Philobryidae. Thirteen CO1 haplotypes were found, mostly unique to the sample regions, and two distinct lineages were distinguished. Specimens from the Weddell and Ross Sea form one lineage while individuals from the banks and islands of the Scotia Sea form the other. Within each lineage, further vicariance was observed forming six regionally isolated groups. Our results provide initial evidence for reproductively isolated populations of L. notorcadensis. The islands of the Scotia Sea appear to act as centres of speciation in the Southern Ocean.

Mollusca collected by Agassiz trawl from the 2016 SO-AntEco Expedition to the South Orkney Islands, Antarctica - data
Mollusca collected by Agassiz trawl from the 2016 SO-AntEco Expedition (JR15005) to the South Orkney Islands, Antarctica - data is an occurrence type dataset published by British Antarctic Survey. Information regarding the Mollusca in this dataset is derived from Agassiz trawl (AGT) samples collected on shelf plateau and slope off the South Orkney Islands, Antarctica, within and outside of the South Orkney Islands Southern Shelf marine protected area. Sampling was conducted in the framework of the British Antarctic Survey/SCAR “South Orkneys - State of the Antarctic Ecosystem” (SO-AntEco) project aboard RRS James Clark Ross during expedition JR15005 in Austral summer 2016. Of 78 successful AGT deployments, 44 trawls at depths ranging from 235-2194 m contained living Mollusca, totaling 2276 individuals, 67 morphospecies and 163 distributional records. Of these, 1999 individuals were Bivalvia (accounting for 15 species), 158 Gastropoda (45 species), 113 Scaphopoda (2 species), 4 Polyplacophora (3 species) and 2 Aplacophora (2 species); empty shells were also collected and recorded in the data table. Three morphospecies (1 Bivalvia and 2 Gastropoda) were collected exclusively as empty shells, thus yielding a total of 70 morphospecies represented in the dataset. All individuals were preserved in undenatured ethanol and are stored as vouchers in the collections of the British Antarctic Survey, Cambridge, United Kingdom. This dataset constitutes a valuable contribution to the knowledge of megafaunal Mollusca associated with a range of benthic habitat types in the South Orkney Islands, an exceptionally diverse region of the Southern Ocean.

Distributional records of sea cucumbers (Echinodermata, Holothuroidea) based on the collection stored at the Italian National Antarctic Museum (MNA, section of Genoa)
Distribution records of sea cucumbers (Echinodermata, Holothuroidea) based on the collection stored at the Italian National Antarctic Museum (MNA, section of Genoa) is an occurrence type dataset published by Italian National Antarctic Museum (MNA). The dataset comprises a total of 328 distributional records, each one corresponding to a voucher specimen stored at the Italian National Antarctic Museum (MNA) – Genoa section. These records originate from the sampling activities performed in the context of eleven different research projects that took place during 11 scientific polar expeditions conducted in the Ross Sea and the Antarctic Peninsula. In total, 89 different sampling events were conducted using a variety of sampling instruments and methodologies. The diversity in the scientific goals of each different research project do not allow to provide a quantitative dataset, also considering that many occurrences were gathered as by-catch, still providing basic metadata such as the geographic coordinates, sampling depth and date and a general description of the adopted sampling methodology. For this reason, this resource must be considered exclusively as a contribution to the distributional knowledge of Antarctic Holothuroidea, especially for the Ross Sea, where most of the occurrences are located, and with a special focus on the Terra Nova Bay area.

Darwin Core Archive of Bacteria and Archaea biodiversity in Arctic and Subarctic terrestrial ecosystems in Alaska
The ascidian, S. adareanum, from the Antarctic Peninsula near Anvers Island, is known to produce a bioactive compound, palmerolide A (PalA) that has specific activity to melanoma, a particularly invasive and metastatic form of skin cancer. The combined non-ribosomal peptide-polyketide structure of PalA has similarities to microbially-produced macrolides which motivated this study utilizing culture-dependent and -independent investigations coupled with PalA detection to improve our understanding of the host-associated microbiome and relationship to PalA. Microbiome composition investigations were conducted to describe the microbiome structure and composition of the Antarctic ascidian, Synoicum adareanum. Metadata sets include (1) ascidian sample collections (63 samples) from the Anvers Island archipelago and associated 16S rRNA gene Illumina tag sequence data sets (V3-V4); palmerolide chemistry data was determined for the same set of 63 samples, and is included with the metadata;(2) bacterioplankton sample collections (14 samples) from the Anvers Island archipelago and associated 16S rRNA gene Illumina tag sequence data sets (V3); (3) bacterial isolate 16S rRNA gene sequences (16 isolates, nearly full length 16S RNA gene), cultivated from Synoicum adareanum homogenates.

The Biodiversity of Ice-free Antarctica Database
Antarctica is one of Earth’s most untouched, inhospitable, and poorly-known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging and spatially explicit compilation of the biodiversity that inhabits Antarctica’s permanently ice-free areas is unavailable. This absence hinders both Antarctic biodiversity research and the integration of Antarctica in global biodiversity-related studies. Fundamental and applied research on biodiversity patterns, ecological structure and function, and options for conservation are reliant on spatially-resolved, taxonomically-consistent observations. Such information is especially important for modern, data-driven biodiversity science, both in Antarctica and globally, and forms the backbone of biodiversity informatics, reflected for example in the Darwin Core Standard used by the Global Biodiversity Information Facility. Biodiversity data are also essential to fulfil the conservation requirements for Antarctica, as set out in the Protocol on Environmental Protection to the Antarctic Treaty and inform the design of systematic surveys to address biodiversity and ecological knowledge gaps, for both specific taxa and ecosystems. Such surveys are key requirements for understanding and mitigating the impacts of environmental change on the region’s biodiversity. Here, we address these requirements through the public release of The Biodiversity of Ice-free Antarctica Database. In 2008, we extracted a subset of biodiversity records only from terrestrial ice-free areas, from the Scientific Committee on Antarctic Research (SCAR) Antarctic Biodiversity Database. We have subsequently added thousands of records from a range of sources; checking, and where necessary (and possible), correcting the spatial location, clarifying, cross-referencing and harmonizing taxonomy with globally-recognized sources, and documenting the original source of records. The Biodiversity of Ice-free Antarctica Database spans the early 1800s to 2019 (with most records collected after 1950) and represents the most comprehensive consolidation of Antarctic ice-free biodiversity occurrence data yet compiled into a single database. The Biodiversity of Ice-free Antarctica Database contains 35,654 records of 1,890 species in over 800 genera across six kingdoms and spans all Antarctic Conservation Biogeographic Regions.Detailed metadata can be found in the Supplementary Materials of: Terauds, A., Lee, J.R., Wauchope, H., Raymond, B., Bergstrom, D.M., Convey, P., Mason, C., Patterson, C.R., Robinson, S.A, Van de Putte, A., Watts, D. and Chown, S.L.

Inter-Valley Soil Comparative Survey of the McMurdo Dry Valleys
Recent applications of molecular genetics to edaphic microbial communities of the McMurdo Dry Valleys and elsewhere have rejected a long-held belief that Antarctic soils contain extremely limited microbial diversity. The Inter-Valley Soil Comparative Survey aims to elucidate the factors shaping these unique microbial communities and their biogeography by integrating molecular genetic approaches with biogeochemical analyses. Although the microbial communities of Dry Valley soils may be complex, there is little doubt that the ecosystem’s food web is relatively simple, and evidence suggests that physicochemical conditions may have the dominant role in shaping microbial communities. To examine this hypothesis, bacterial communities from representative soil samples collected in four geographically disparate Dry Valleys were analyzed using molecular genetic tools, including pyrosequencing of 16S rRNA gene PCR amplicons. Results show that the four communities are structurally and phylogenetically distinct, and possess significantly different levels of diversity. Strikingly, only 2 of 214 phylotypes were found in all four valleys, challenging a widespread assumption that the microbiota of the Dry Valleys is composed of a few cosmopolitan species. Analysis of soil geochemical properties indicated that salt content, alongside altitude and Cu2+, was significantly correlated with differences in microbial communities. Our results indicate that the microbial ecology of Dry Valley soils is highly localized and that physicochemical factors potentially have major roles in shaping the microbiology of ice-free areas of Antarctica. These findings hint at links between Dry Valley glacial geomorphology and microbial ecology, and raise previously unrecognized issues related to environmental management of this unique ecosystem.

MNA Italica 2004_Rauschert dredge_Ross_sea_Mollusca_lgp
Information regarding the molluscs in this dataset is based on the Rauschert dredge samples collected during the Latitudinal Gradient Program (LGP) on board the R/V “Italica” in the Ross Sea (Antarctica) in the austral summer 2004. A total of 18 epibenthic dredge deployments/samplings have been performed at four diffrent locations at depths ranging from 84 to 515m by using a "Rauschert" dredge with a mesh size of 500μm. In total 8,359 specimens have been collected belonging to 161 species and corresponding to 505 species distributional records. Of these, in order of abundance, 5,965 specimens were Gastropoda (accounting for 113 species), 1,323 were Bivalvia (accounting for 36 species), 949 were Aplacophora (accounting for 7 species), 74 specimens were Scaphopoda (3 species), 38 were Monoplacophora (1 species) and, finally, 10 specimens were Polyplacophora (1 species). This data set represent the first large-scale survey of benthic micromolluscs for the area and provides important information about the distribution of several species which have been seldom or never recorded before in the Ross Sea. All vouchers are permanently stored at the Italian National Antarctic Museum (MNA), Section of Genoa, enabling future comparison and crosschecking. This material is also currently under study, from a molecular point of view, by the barcoding project "BAMBi" (PNRA 2010/A1.10).

Antarctic, Sub-Antarctic and cold temperate echinoid database
This database includes spatial data of Antarctic, Sub-Antarctic and cold temperate echinoid distribution (Echinodermata: Echinoidea) collected during many oceanographic campaigns led in the Southern Hemisphere from 1872 to 2010. The dataset lists occurrence data of echinoid distribution south of 35°S latitude, together with information on taxonomy (from species to genus level), sampling sources (cruise ID, sampling dates, ship names) and sampling sites (geographic coordinates and depth). Echinoid occurrence data were compiled from the Antarctic Echinoid Database (David et al., 2005a), which integrates records from oceanographic cruises led in the Southern Ocean until 2003. This database has been upgraded to take into account data from oceanographic cruises led after 2003. The dataset now reaches a total of 6160 occurrence data that have been checked for systematics reliability and consistency. It constitutes today the most complete database on Antarctic and Sub-Antarctic echinoids.

The phylogenetic relationships of 14 species of the Antarctic amphipod families Epimeriidae and Iphimediidae were investigated using 553 bp of the gene for the mitochondrial cytochrome oxidase subunit I (COI) and 98 morphological characters. Both families are dominant members of the Antarctic benthic amphipod community. In contrast to previous studies, our molecular and morphological data suggest that the families Epimeriidae and Iphimediidae may not be sister taxa. Our study suggests that Iphimediidae are more closely related to Eusirus (Eusiridae) than to Epimeria (Epimeriidae). Phylogenetic analyses based on maximum parsimony (MP) and maximum likelihood (ML) indicate that the genera Iphimediella and Gnathiphimedia are not monophyletic.

The total number of bacteria and culturable bacteria in Ade´lie penguin (Pygoscelis adeliae) guano was determined during 42 days of decomposition in a location adjacent to the rookery in Admiralty Bay, King George Island, Antarctica. Of the culturable bacteria, 72 randomly selected colonies were described using 49 morpho-physiological tests, 27 of which were subsequently considered significant in characterizing and differentiating the isolates. On the basis of the nucleotide sequence of a fragment of the 16S rRNA gene in each of 72 pure isolates, three major phylogenetic groups were identified, namely the Moraxellaceae/Pseudomonadaceae (29 isolates), the Flavobacteriaceae (14), and the Micrococcaceae (29). Grouping of the isolates on the basis of morpho-physiological tests (whether 49 or 27 parameters) showed similar results to those based on 16S rRNA gene sequences. Clusters were characterized by considerable intra-cluster variation in both 16S rRNA gene sequences and morpho-physiological responses. High diversity in abundance and morphometry of total bacterial communities during penguin guano decomposition was supported by image analysis of epifluorescence micrographs. The results indicate that the bacterial community in penguin guano is not only one of the richest in Antarctica, but is extremely diverse, both phylogenetically and morpho-physiologically.

Myctobase, a circumpolar database of mesopelagic fishes for new insights into deep pelagic prey fields - data
The global importance of mesopelagic fish is increasingly recognised, but they remain relatively poorly studied. This is particularly true in the Southern Ocean, where mesopelagic fishes are both key predators and prey, but where the remote environment makes sampling challenging. Despite this, multiple national Antarctic research programs have undertaken regional sampling of mesopelagic fish over several decades. However, data are dispersed, and sampling methodologies often differ precluding comparisons and limiting synthetic analyses. We identified potential data holders by compiling a metadata catalogue of existing survey data for Southern Ocean mesopelagic fishes. Data holders contributed 17,491 occurrence and 11,190 abundance records from 4780 net hauls from 72 different research cruises. Data span across 37 years from 1991 to 2019 and include trait-based information (length, weight, maturity). The final dataset underwent quality control processes and detailed metadata was provided for each sampling event. This dataset can be accessed through the Antarctic Biodiversity Portal. Myctobase will enhance research capacity by providing the broadscale baseline data necessary for observing and modelling mesopelagic fishes. The paper which this dataset refers to is available at https://doi.org/10.1038/s41597-022-01496-y. The original dataset as submitted for the paper is also available on Zenodo at https://doi.org/10.5281/zenodo.6131579. This dataset is published by SCAR-AntOBIS under the license CC-BY 4.0.

Antarctic Starfish (Echinodermata: asteroidea) from the ANDEEP3 expedition
This dataset includes information on sea stars collected during the ANDEEP3 expedition, which took place in 2005. The expedition focused on deep-sea stations in the Powell Basin and Weddell Sea. Sea stars were collected using an Agassiz trawl (3m, mesh-size 500µm), deployed in 16 stations during the ANTXXII/3 (ANDEEP3, PS72) expedition of the RV Polarstern. Sampling depth ranged from 1047 to 4931m. Trawling distance ranged from 731 to 3841m. The sampling area ranges from -41°S to -71°S (latitude) and from 0 to -65°W (longitude). A complete list of stations is available from the PANGAEA data system (http://www.pangaea.de/PHP/CruiseReports.php?b=Polarstern), including a cruise report (http://epic-reports.awi.de/3694/1/PE_72.pdf). The dataset includes 50 records, with individual counts ranging from 1-10, reaching a total of 132 specimens. The andeep3-Asteroidea is a unique dataset as it covers an under-explored region of the Southern Ocean, and that very little information was available regarding Antarctic deep-sea star fish. Before this study, most of the information available focused on star fish from shallower depths than 1000m. This dataset allowed to make unique observations, such as the fact that some species were only present at very high depths (Hymenaster crucifer, Hymenaster pellucidus, Hymenaster praecoquis, Psilaster charcoti, Freyella attenuata, Freyastera tuberculata, Styrachaster chuni and Vemaster sudatlanticus were all found below -3770m), while others displayed remarkable eurybathy, with very high depths amplitudes (Bathybiaster loripes (4842m), Lysasterias adeliae (4832m), Lophaster stellans (4752m), Cheiraster planeta (4708m), Eremicaster crassus (4626m), Lophaster gaini (4560m) and Ctenodiscus australis (4489m)). Even if the number of records is relatively small, the data bring many new insights on the taxonomic, bathymetric and geographic distributions of Southern starfish, covering a very large sampling zone. The dataset also brings to light six species, newly reported in the Southern Ocean. The quality of the data was controlled very thoroughly, by means of on-board Polarstern GPS systems, checking of identification by a renowned specialist (Prof. Michel Jangoux, Université Libre de Bruxelles), and matching to the Register of Antarctic Marine Species (RAMS) and World Register of Marine Species (WoRMS). The data is therefore fit for completing checklists, for inclusion in biodiversity patterns analysis, or niche modeling. It also nicely fills an information gap regarding deep-sea starfish from the Southern Ocean, for which data is very scarce at this time. The authors may be contacted if any additional information is needed before carrying out detailed biodiversity or biogeographic studies.

Surface sediment samples were collected using a Van Veen grab and biological samples were collected using a Van Veen grab, a Rauschert dredge and a rock dredge deployed at multiple stations around King George Island and Deception Island (South Shetland Islands), in the Bransfield Strait and in Hope Bay (Antarctic Peninsula). Sediment samples were collected and dried on board with decontaminated equipment and analyzed for trace element concentrations using ICP-MS in the lab of the Analytical, Environmental & Geo-Chemistry research group of the VUB, Belgium. Biological samples could not be sorted on board but were conserved for further analysis at the Royal Belgian Institute of Natural Sciences, Belgium. The dataset gives an overview on the distribution and abundance of species in the north of the Antarctic Peninsula during the summer season as well as baseline trace element concentrations and distribution in the surface sediments. Sediment samples are published in Delhaye et al. (2023). Please follow the guidelines from the SCAR Data Policy (SCAR, 2023) when using the data.

Information regarding the molluscs in this dataset is based on the epibenthic sledge (EBS) samples collected during the cruise BIOPEARL II / JR179 RRS James Clark Ross in the austral summer 2008. A total of 34 epibenthic sledge deployments have been performed at five locations in the Amundsen Sea at Pine Island Bay (PIB) and the Amundsen Sea Embayment (ASE) at depths ranging from 476 to 3501m. This presents a unique and important collection for the Antarctic benthic biodiversity assessment as the Amundsen Sea remains one of the least known regions in Antarctica. Indeed the work presented in this dataset is based on the first benthic samples collected with an EBS in the Amundsen Sea. However we assume that the data represented are an underestimation of the real fauna present in the Amundsen Sea. In total 9261 specimens belonging to 6 classes 55 families and 97 morphospecies were collected. The species richness per station varied between 6 and 43. Gastropoda were most species rich (50 species) followed by Bivalvia (37), Aplacophora (5), Scaphopoda (3) and one from each of Polyplacophora and Monoplacophora.

Large sessile habitat-forming organisms such as sponges, corals, bryozoans and hydroids play a crucial role in the structure of Antarctic marine communities and enhance the local biodiversity. Not only are there many species of these groups found in the Antarctic (387 sponges, 141 corals, 320 bryozoans and 337 hydroids) but they also form vital habitats for countless other organisms. The habitats formed by these megafaunal organisms are increasingly being recognized as both vulnerable and important ecosystems. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) adopted a proposal to declare two areas of the Southern Ocean as Vulnerable Marine Ecosystems (VMEs). Both areas proposed are highly biodiverse, particularly with respect to habitat-forming hydrocorals, sponges and associated fauna.

Biogeographic distribution of the Antarctic and Sub-Antarctic brachiopods (living forms)
The only Antarctic review about brachiopods has been done by Forster in 1974. Since about 100 publications dealing with living Antarctic brachiopods have been issued and nearly 50 on fossil Antarctic brachiopods, until 2009. The classification of the Brachiopoda has been basically changed in 1996 and developed in the 6 volumes of the “Treatise” (1997-2007). All specialists of living brachiopods are now retired (less than 5!). Consequently, the distributional biodiversity of the extant brachiopods must be stored online as soon a possible. This task will be difficult to be completed in a next future. For the proposed work all the available publications (about 150) on living brachiopods will be analyzed, as well the citations on living forms included in the palaeontological papers. The dataset holds taxonomic and distribution data on Brachiopoda (lamp-shells) from the Antarctic and Subantarctic regions. The sources of the information (bibliography and expeditions) are also provided.

Walter Herwig 1978 (FFS): SeaStars (Echinodermata, Asteroidea)
This dataset includes information on sea stars collected during one of the Walter Herwig expeditions (1978). Sampling took place during the FFS (Fischereiforschungsschiff) voyage. The expedition focused on the continental shelf of Patagonia, down to the Falklands (Malvinas) Islands. The asteroids of the Walter Herwig FFS expedition have been identified in detail, based on the observation of external morphological characters using a binocular microscope. A wide variety of morphological characters was taken into consideration for the identification of the asteroids. For instance, shape and size of the pedicellaria, the skeletal structure (réseau squelettique) and the ossicles that form the mesh (number of spines/ossicle), thickness and aspect of the body wall, the position of the papula, the number of podia rows and the shape of the podia, structure and armature of the marginal plates, number and form of the adambulacral spines as well as the spines of the dental plates, etc. By means of a preexisting identification key of Atlantic asteroids (A.M. Clark, 1994), the observation of the morphological characters permitted to identify the order, the family, the genus and sometimes the species to which the considered individual belonged to. For the time being, there are no existing identification keys for Antarctic asteroids. For this reason, we consulted in addition multiple works of previous Antarctic expeditions (A.M. Clark (1962, 1994), R. Köhler (1906, 1907, 1908, 1911, 1912, 1917, 1920, 1923), W.K. Fisher (1911,1940), Sladen (1889), Mortensen (1932), E. Perrier (1891a), H. Ludwig (1905), Th. Studer (1874), I. Bernasconi (1967, 1964, 1966, 1972), Madsen (1950)) which allowed us to improve the identifications in dubious cases, thanks of their numerous detailed illustrations and descriptions of Antarctic asteroids. Synonymy was resolved by consulting the Register of Antarctic Marine Species (RAMS), that is accessible via internet and that compiles the most recent information about Antarctic asteroid taxonomy (Danis & Jangoux, 2007), delivering us in this way the valid species names.

Marine bacterioplankton community structure in the vicinity of Antarctic icebergs
We studied marine bacterioplankton in the Scotia Sea in June 2008 and in the northwest Weddell Sea in March to mid April 2009 in waters proximal to three free-drifting icebergs (SS-1, A-43k, and C-18a), in a region with a high density of smaller icebergs (iceberg alley), and at stations that were upstream of the iceberg trajectories designated as far-field reference sites that were between 16-75 km away. Hydrographic parameters were used to define water masses in which comparisons between bacterioplankton-associated characteristics within and between water masses could be made. Influences of the icebergs on early winter Scotia Sea bacterioplankton were minimal, if not deleterious, as we found lower levels of heterotrophic production near A-43k in comparison to stations > 16 km away. Small but significant differences in bacterioplankton community structure were observed between two icebergs studied in early winter Scotia Sea. These icebergs differed greatly in size and the findings suggest that the larger iceberg had a greater effect. In the NW Weddell Sea in March–mid April there were some significant differences in community structure in the winter water and underlying upper circumpolar deep water masses between stations occupied close to C-18a and at stations 18 km away (i.e. Polaribacter and Pelagibacter-related 16S rRNA gene fragments were at low levels at the 18 km stations), though higher resolution, high throughput profiling tools will be needed to pinpoint specific organisms and ecological types. Likewise, a better understanding of local to regional scale structure of bacterioplankton communities is necessary. Overall, the results show that bacterioplankton, dominated by Rhodobacteracae Pelagibacter, and uncultivated Gammaproteobacteria groups were minimally influenced by icebergs in the regions and seasons studied here – at least directly – though further work addressing different scales, sizes of icebergs, and seasons is needed to better understand bacterioplankton-associated ecological processes and carbon cycling in regions of high iceberg production.

Winter Picoplankton Diversity and Distribution in the US Antarctic Marine Living Resources Study Area - Northern Antarctic Peninsula
Picoplankton (bacteria, archaea, and eukaryotic organisms < 3.0 micron) surveys conducted in collaboration with the U.S. Antarctic Marine Living Resources (AMLR) field research program aimed to study the pelagic ecosystem during month-long winter research cruises in the South Shetland Islands, Scotia Sea and the NW Weddell Sea regions in August, 2012, 2013, and 2014. This inter-annual study on the winter pelagic ecosystem follows a 25-year time series program studying austral summer waters, though is the first survey to also include the characterization of the picoplankton in this study area. The primary goal of the AMLR winter cruise was to establish the ecological importance of winter processes and plankton distributons particularly as related to sea ice and to capture the hydrography and winter distributions of krill for comparisons with summer conditions over this long times series study. The winter time study will help determine how the template for ecological success is set up for summertime production across all trophic levels. The picoplankton research will improve the understanding of winter distributions and provide sample collection opportunities for diversity and biogeochemical studies to create an integrated ecosystem picture that will be developed with the NOAA AMLR group. In particular, this effort will extend the geographic coverage of winter picoplankton in the South Shetland Islands region, both on and off the continental slope. This is important to test hypotheses concerning high latitude winter processes that were observed in coastal Antarctic Peninsula waters suggesting the relative importance of chemolithoautotrophy is a key winter-time metabolic process.

Porifera collection of the Italian National Antarctic Museum (MNA) - Data
This new dataset presents occurrence data for Porifera collected in the Ross Sea, mainly in the Terra Nova Bay area, and curated at the Italian National Antarctic Museum (MNA, section of Genoa). Specimens were collected in 331 different sampling stations at depths ranging from 17 to 1100 meters in the framework of 17 different Italian Antarctic expeditions funded by the Italian National Antarctic Research Program (PNRA). A total of 807 specimens, belonging to 144 morphospecies (i.e. 95 taxa identified at species level and 49 classified at least at the genus level), are included in the dataset. Nearly half (45%) of the species reported here correspond to species already known for Terra Nova Bay. Out of the remaining 55% previously unknown records, under a third (~29%) was classified at the specific level, while over a quarter (~26%) was ascribed to the genus level only and requires further study. All vouchers are permanently curated at the MNA and are available for study to the scientific community. A 3D model of an uncommon species from the Ross Sea, i.e. Tethyopsis brondstedi (Burton, 1929), is also presented here and will be made available for outreach purposes.

Antarctic krill (Euphausia superba) and salps are major macroplankton contributors to Southern Ocean food webs and krill are also fished commercially. Managing this fishery sustainably, against a backdrop of rapid regional climate change, requires information on distribution and time trends. Many data on the abundance of both taxa have been obtained from net sampling surveys since 1926, but much of this is stored in national archives, sometimes only in notebooks. In order to make these important data accessible we have collated avail- able abundance data (numerical density, no. m−2) of postlarval E. superba and salp individual (multiple species, and whether singly or in chains). These were combined into a central database, KRILLBASE, together with en- vironmental information, standardisation and metadata. The aim is to provide a temporal-spatial data resource to support a variety of research such as biogeochemistry, autecology, higher predator foraging and food web mod- elling in addition to fisheries management and conservation. Previous versions of KRILLBASE have led to a series of papers since 2004 which illustrate some of the potential uses of this database. With increasing numbers of requests for these data we here provide an updated version of KRILLBASE that contains data from 15 194 net hauls, including 12 758 with krill abundance data and 9726 with salp abundance data. These data were collected by 10 nations and span 56 seasons in two epochs (1926–1939 and 1976–2016). Here, we illustrate the seasonal, inter-annual, regional and depth coverage of sampling, and provide both circumpolar- and regional-scale distri- bution maps. Krill abundance data have been standardised to accommodate variation in sampling methods, and we have presented these as well as the raw data. Information is provided on how to screen, interpret and use KRILLBASE to reduce artefacts in interpretation, with contact points for the main data providers.

This dataset describes a 16S ribosomal DNA clone library analysis, performed to assess archaeal diversity within three surficial sediment samples obtained from the bathypelagic zone (depth : 2,165 -3,406 m) of the Weddell Sea, Antarctica. The nearly complete 16S rDNA gene (1440 bp) was obtained for 146 clones and 46 phylotypes were defined. The majority of the sequences (> 99%) formed three clusters within the Marine Group I Crenarchaeota. The most important cluster, with 78.8% of the clones, included Candidatus Nitrosopumilus maritimus, a mesophilic archaeon able to oxidize ammonia. The most important subgroup in that cluster was the APA4-0cm subgroup (with 62.3% of the clones). This subgroup might represent important Crenarchaeota in the functioning of the bathypelagic sedimentary ecosystems of the Weddell Sea because it dominated the clone libraries in all sampling stations, and was found in sediments separated by very large geographic distances. Only one clone grouped within the Euryarchaeota. This euryarchaeal clone could not be affiliated with any of the previously defined clusters and might represent a novel Euryarchaeal lineage

SOMBASE – Southern Ocean mollusc database: a tool for biogeographic analysis in diversity and evolution
Databases and Geographical Information Systems are becoming increasingly popular tools for biogeographic analysis. The reliability of the analysis depends on the accuracy of the entered data and the ability to add changes in systematics and taxonomy. The main aim of the Southern Ocean Mollusc Database (SOMBASE) project is to set up a database linked with a GIS and user-friendly front end. This system allows for the inclusion of other taxa in the future. Currently the database consists of records for 950 shelled gastropod and 136 bivalve species and 2800 sites from the Southern Ocean.The database contains fields including: 1) Taxonomic authorship, synonyms, higher level classifications, diagnostic morphological characters, and ecological features; 2) Distributional information including substrate and depth; 3) Bibliographic information.The maps can display selected sites based on any query of any field or combination of fields in the database. An online version of the database is available with distribution maps for all taxonomic levels (www.antarctica.ac.uk/SOMBASE). SOMBASE is a contribution to the Biogeiegraphic Atlas of the Southern Ocean

Argentina–Chile National Geographic Pristine Seas Expedition To The Antarctic Peninsula - Deep Sea Cam Data
In January 2019, the governments of Chile and Argentina, in collaboration with National Geographic Pristine Seas, organized an expedition to the Antarctic Peninsula, with the aim to provide political, scientific, and communication support, at a global scale, to the Marine Protected Area proposal for the Antarctic Peninsula-South Scotia Arc (Domain 1 MPA or D1MPA) that was put forward jointly by the two countries in October 2018. To this end, they set out to explore the ecosystems of the continental shelf along the WAP and associated islands using National Geographic’s deep-sea cameras to capture high quality imagery of areas of the Antarctic sea floor and the associated fauna, which have been comparatively less well explored. This bi-national expedition was conducted on the Chilean Navy vessel, the OPV-83 Marinero Fuentealba, with scientists from both countries national Antarctic Institutes. In order to study the continental shelf faunal biodiversity of Antarctica , baited cameras were deployed at 20 locations along ~ 500 km of the Western Antarctic Peninsula (WAP) at depths from 90 to 797 m.

CEAMARC Eastern Antarctic Gelatinous Mesozooplankton (Cnidaria and Ctenophora)
This dataset holds occurrence data of gelatinous mesozooplankton species (Cnidaria and Ctenophora) that was collected during the Japanese contribution to the Collaborative East Antarctic Marine Census (CEAMARC) project. CEAMARC was a multinational contribution to the Census for Antarctic Marine Life (CAML, IPY Project 53). It involved scientists and students from several nations using three ships from Australia, Japan and France surveying the one area. This collaboration was a highly coordinated and comprehensive survey of the plankton, fish, benthos, oceanography and geophysical conditions of the waters north of Terre Adélie and George V Land of Eastern Antarctica. CEAMARC has provided a robust benchmark of the marine life in this poorly studied sector and will help to establish the monitoring of future changes in this region.

Asteroids, ophiuroids and holothurians from the South-Eastern Weddell Sea (Southern Ocean)
The South-Eastern Weddell Sea in the Atlantic Sector of the Southern Ocean is a typical high-latitude Antarctic region. It is located in the circumpolar permanent pack-ice zone (Hempel 1985a), characterized by summary polynyas (areas of open water surrounded by sea ice). Due to its remoteness and persistent sea-ice cover, it was not accessible for extensive scientific surveys before the availability and support of modern research platforms that are capable to operate independently in sea-ice covered waters. First multidisciplinary marine research was carried out in this area in the 1980s during the first Antarctic cruises of the German icebreaking research and supply vessel "Polarstern”. Embedded in a broad ecological research programme, addressing a range of evolutionary, systematic, zoogeographical and ecological issues, first comprehensive faunistic inventories of the asteroid (starfish), ophiuroid (brittle star) and holothurian (sea cucumber) bottom fauna were conducted, based on field sampling efforts during “Polarstern” cruises ANT-I/2 (PS01), ANT-II/04 (PS04), and ANT-III/3 (PS06) (for cruise reports see Hempel 1983, Drescher et al. 1983, Kohnen 1984, and Hempel 1985b, respectively). The major objective of this collection work was to provide material for subsequent zoogeographical and ecological studies on the asterozoan (asteroid and ophiuroids together; Voß 1988, Piepenburg et al. 1997) and holothurian fauna (Gutt 1988, Gutt 1991), as well as for analyses of entire macrozoobenthos communities (Gutt 2000; for a compilation: Gutt et al. 2013). Here, we publish the complete original dataset of asteroid, ophiuroid and holothurian abundances (and absences) that formed the basis of the scientific findings published in the research papers mentioned above, to allow for the general accessibility to such data associated with starfishes, brittle stars and sea cucumbers from the South-Eastern Weddell Sea. Asteroid, ophiuroid, and holothurian specimens were sampled at a total of 59 sites distributed across the South-Eastern Weddell Sea at water depths between 160 and 1,180 m (for more detailed information see section on “Geographic coverage” below). In general, this region characterized by a relatively homogenous physical environment, especially in terms of water masses, poorly sorted sediments, persistent sea-ice cover and hardly predictable occurrence of coastal polynyas. As such, it is representative for the entire high-latitude Antarctic habitat. Some drivers of faunistic heterogeneity, in addition to biological interactions and unknown unpredictable factors, are briefly summarized in the section on “Project Data - Study area description” below. The field samples were mainly taken by means of an Agassiz trawl, but also with a commercial bottom trawl and, in one case, a smaller dredge. During the cruises, GPS positions were available approximately each six hours. Between the GPS fixes, the ship's positions were death reckoned. Swept areas were estimated for each haul as described in Voß (1988) and Gutt (1988). Water depths were measured by a DWD echo sounder. For more detailed information see section on “Sampling methods - Sampling description” below. Specimens were collected from either total catches or, in some cases subsamples, counted and preserved on board. Using the swept-area estimates, individual counts were standardized to abundance values (ind m^-2). After the cruises, the preserved specimens were identified to species in the lab. Some holothurian species, which were assumed to be new to science, were formally described (Gutt 1990a, b). Some of these new descriptions were later revised. The specimens were not integrated into a museum's collection, and original data were never published at that time when electronic data bases did not yet exist. The quality of the data and metadata published here was enhanced prior to publication following the best practices suggested in the literature during the digitalization and geo-referencing processes. Moreover, the current accurate spelling of scientific names - except for the ophiuroid Theodoria conveniens ("nomen dubium") - was reviewed based on the World Register of Marine Species (www.marinespecies.org/). For more information see “Sampling methods - Quality control” below. The dataset comprises a total of 4,509 records of absences and abundances of 35 asteroid species (with a total of 2,089 specimens) and 38 opiuroid species (with a total of 18,484 specimens) from 34 stations, as well as of 66 holothurian species (with a total of 20,918 specimens) from 59 stations. Asteroid, ophiuroid and holothurian species were present at all sites investigated in the study area but composition and abundance of the asterozoan and holothurian assemblages varied considerably. In the case of asterozoan patterns (Voß 1988, Piepenburg et al. 1997), water depth and latitude seemed to be the most important drivers of assemblage distribution and composition. At shallow shelf sites rare asteroid and ophiuroid predators, such as, e.g., Acodontaster conspicuus and Odontaster validus, respectively, as well as epibiotic ophiuroids, e.g., Astrotoma agassizii, occurred in addition to the common and widely distributed opportunistic feeders. In the case of holothurians (Gutt 1988, Gutt 1991), one assemblage co-occurred with the rich macrozoobenthic community dominated by dense epifauna consisting of, e.g., sponges and gorgonians, which are often used as substratum by epibiotic filter feeders. Others live mainly as vagrant deposit feeders on the predominantly non-colonised substratum, such as typical deep-sea species, e.g. Elpidia glacialis and Protelpidia murrayi (Gutt and Piepenburg 1991). In addition, a mixed holothurian assemblage was identified. Virtually nothing was known about echinoderms in the south-eastern Weddell Sea before the field sampling work, in the course of which the data published here have been gained. Also from other Antarctic regions only sporadic information on the three echinoderm classes, especially holothurians, was available at that time, mainly found published in the taxonomic literature. However, the application of a whole-assemblage approach was novel, and comparable surveys are even nowadays rare. The unique dataset encompasses some of the first observations of asteroids, ophiuroids and holothurians in this area and represents a significant contribution of primary data about Antarctic benthos assemblages. Moreover, it provides unique baseline data for future faunistic, ecological and conservation studies to evaluate the effects of climate change and possible future fishing activities in this area. At present and in the future these faunistic data can gain further importance in the context of a number of further applications: (1) More comprehensive circumpolar analyses and comparative studies with other large taxa become possible if these data are merged with similar datasets from other regions, see e.g., http://ipt.biodiversity.aq/resource.do?r=asteroidea_zoogeography and http://ipt.biodiversity.aq/resource.do?r=biopearl_asteroida. Data on these three echinoderm classes can also be compared within the same region with other taxa or environmental parameters, as compiled, e.g., by De Broyer et al. (in press). (2) At the time of sampling in the 1980s, the study area was almost pristine and hardly affected by any anthropogenic activities. In the meantime, exploratory fishing started on the deeper shelf, and the knowledge on the fauna before the onset of these activities can serve as a valuable baseline for an assessment of the impact of further fishing. (3) The same holds true for the study of the effects of climate change. The area is so far climatologically relatively stable but an increase of bottom-water temperatures is expected during the 21st century (Hellmer et al. 2012). (4) The data can also be used for nature conservation initiatives (Teschke et al. 2013). They are especially suited for such applied ecological comparative studies, since all specimens - with few well-defined exceptions - were sorted from the catches, meaning that not only the presence of the species were registered but also very valuable absence data and the even more informative abundances. In general, the latter data are known to be more sensitive indicators of environmental change than binary presence-absence data.

SCAR Biogeographic Atlas of the Southern Ocean - Benthic Ostracoda - Data
This dataset represents a literature study on the distribution of fossil and recent benthic Ostracoda (Crustacea) from the Southern Ocean, with only a few records of planktonic taxa. Dataset supplied in the framework of the SCAR Biogeographic Atlas of the Southern Ocean (BASO). The Biogeographic Atlas of the Southern Ocean is a collection of representative maps and syntheses on the distribution of the Southern Ocean organisms, providing a general overview of the biogeography of the Southern Ocean (s.l.) and a benchmark of current biogeographic knowledge at the end of the Census of Antarctic Marine Life. This updates the well-known and useful but largely outdated biogeographic Folios of the Antarctic Map Folio Series (American Geographical Society). These records were compiled from 81 papers. A few papers were not included in the dataset because they were either compilations of previous studies: i.e., Brandt, Gooday, Brandão,et al., 2007; Dingle, Lord, Boomer, 1989; Majoran, Dingle, 2001; Majoran, Dingle, 2002; Seeling, Colin, Fauth, 2004. Some "old" papers are included in the dataset but their records should not be included in biogeographic, macroecological analyses, because there are too many misidentifications (i.e. Brady, 1880; Chapman, 1915; CHapman, 1919). The following papers contain information on Southern Ocean Ostracoda, but were not included in the dataset because I (Brandao, S.N.) did not have access to them: Chapman, 1916a; Chapman, 1916; Cusminsky, Whatley, 2008; Gao, Zhang, 1986; Gazdzicki, 1996; Gazdzicki, 2001; Gou, 1994; Lofthouse, 1967; Müller, 1911; Poulsen, 1962; Setty, 1984; Scott, 1912; Whatley, Ramos, Moguilevsky, Chadwick, 1998.

The biodiversity research expedition TAN0204 with RS Tangaroa to the Ross Sea in 2004 yielded a new collection of 2,687 specimens of pycnogonids. As much as 25 dfferent species encompassing 14 genera and eight families were identified and their records are discussed herein. The collection is archived in the Marine Invertebrate Collection of the New Zealand National Institute of Water and Atmospheric Research (NIWA). The majority (69%) of specimens are from the Nymphon australe group (Nymphonidae), although species richness and abundance varied among the stations sampled. The collection includes several specimens from polymerous taxa; Pentanymphon antarcticum (Nymphonidae), Decolopoda australis (Colossendeidae) and Pentapycnon bouvieri (Pycnogonidae). All species were classified based on morphological characters, and DNA sequences (from the 18S, 12S, 16S and COI regions) for 21 of the representative morphotypes are given. The DNA sequences confirmed the species-level distinctiveness of these morphotypes.

East Weddell Sea echinoids from the JR275 expedition
Information regarding the echinoids in this dataset is based on the Agassiz Trawl (AGT) and epibenthic sledge (EBS) samples collected during the British Antarctic Survey cruise JR275 on the RRS James Clark Ross in the austral summer 2012. A total of 56 (1 at the South Orkneys and 55 in the Eastern Weddell Sea) Agassiz Trawl and 18 (2 at the South Orkneys and 16 in the Eastern Weddell Sea) epibenthic sledge deployments were performed at depths ranging from ~280 to ~2060 m. This presents a unique collection for the Antarctic benthic biodiversity assessment of an important group of benthic invertebrates. In total 487 specimens belonging to six families, 15 genera, and 22 morphospecies were collected. The species richness per station varied between one and six. Total species richness represents 27% of the 82 echinoid species ever recorded in the Southern Ocean (David et al. 2005b, Pierrat et al. 2012, Saucède et al. 2014). The Cidaridae (sub-family Ctenocidarinae) and Schizasteridae are the two most speciose families in the dataset. They comprise seven and nine species respectively. This is illustrative of the overall pattern of echinoid diversity in the Southern Ocean where 65% of Antarctic species belong to the families Schizasteridae and Cidaridae (Pierrat et al. 2012).

In Antarctic waters, the superfamily Lysianassoidea is one of the most important amphipod groups both in terms of species number and abundance. Dominant members of this superfamily are species of the orchomenid complex, found throughout the Southern Ocean. This study presents the first molecular phylogenetic analysis based on a representative subset of the Antarctic species belonging to different orchomenid genera and hence provides a framework for a systematic revision of these taxa. The current classification of the orchomenid genera is mainly based on mouthpart morphology. The validity of these morphological characters was assessed by resolving phylogenetic relationships using nuclear 28S rRNA and mitochondrial cytochrome oxidase subunit I sequences. The molecular data rejected most of the previously proposed taxonomic subdivisions within this complex. The genera Abyssorchomene and Orchomenella as well as the subgenus Orchomenopsis appeared to be non-monophyletic. This implies that the supposed diagnostic characters are likely a result of convergent evolution. Further, our results indicated the necessity of a revision of the family-level systematics.

Epipelagic mesozooplankton distribution and abundance in Southern Ocean Atlantic sector and the North Atlantic and Arctic 1996-2013
Mesozooplankton were collected with a motion-compensated Bongo net (61 cm mouth diameter, 100 and 200 micrometre meshes) and a mini- Bongo net (18 cm mouth diameter, 50 micrometre mesh nets). Both nets fished to a maximum depth of 400 m but sometimes shallower. Specimens were categorised to the lowest possible taxonomic level, which in some cases encompassed developmental stages but in other cases was limited to higher order taxa. Each taxa was enumerated to determine abundance in units of individuals m-2. The dataset allows examination of the distribution and abundance of these species within the Atlantic sector of the Southern Ocean over a number of years and covering much of the productive season from spring to autumn. The data for the North Atlantic and Arctic covers one season only (summer) and is limited to providing a spatial perspective on the distribution and abundance of mesozooplankton.

Antarctic fish Gobionotothen gibberifrons
The diversification of the teleost suborder Notothenioidei (Perciformes) in Antarctic waters provides one of the most striking examples of a marine adaptive radiation. Along with a number of adaptations to the cold environment, such as the evolution of antifreeze glycoproteins, notothenioids diversified into eight families and at least 130 species. Here, we investigate the genetic population structure of the humped rockcod (Gobionotothen gibberifrons), a benthic notothenioid fish. Six populations were sampled at different locations around the Scotia Sea, comprising a large part of the species’ distribution range (N = 165). Our analyses based on mitochondrial DNA sequence data (352 bp) and eight microsatellite markers reveal a lack of genetic structuring over large geographic distances (¦ST £ 0.058, FST £ 0.005, P values nonsignificant). In order to test whether this was due to passive larval dispersal, we used GPS-tracked drifter trajectories, which approximate movement of passive surface particles with ocean currents. The drifter data indicate that the Antarctic Circumpolar Current (ACC) connects the sampling locations in one direction only (west–east), and that passive transport is possible within the 4-month larval period of G. gibberifrons. Indeed, when applying the isolation-with-migration model in IMA, strong unidirectional west-east migration rates are detected in the humped rockcod. This leads us to conclude that, in G. gibberifrons, genetic differentiation is prevented by gene flow via larval dispersal with the ACC. Keywords: adaptive radiation, population genetics, isolation-with-migration model, drifters

BCCM/ULC Cyanobacteria culture collection at the University of Liège (ISO9001 certified)
BCCM/ULC is a small and dedicated public culture collection, currently containing one of the largest collections of documented (sub)polar cyanobacteria worldwide. The BCCM/ULC collection is hosted by the Centre for Protein Engineering (the Unit) of the University of Liège. The host Unit is very active in research projects concerning the cyanobacterial diversity and biogeography, with a focus on polar biotopes. The approach used is polyphasic, including the isolation of strains and culture-independent methods (DGGE, clone libraries, pyrosequencing based on the ribosomal operon sequences). The participation to field expeditions in the Antarctic and Arctic has enabled to collect samples in many locations. Moreover, taxonomic research is carried out by the host Unit to improve the classification of the cyanobacterial phylum. It is based on a polyphasic approach combining the morphological and molecular characterizations of the strains.
