2017-10-05 eng 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).

The material was collected during the Italica 2004 LGP Italica 2004 Expedition by Dr. Peter Rehm (see Rehm et al., 2006) under the framework of the PNRA Project 2002/8.6. In the specific, the Rauschert samples were preserved immediately in pre-cooled 90% ethanol and kept in -25°C for later DNA extraction. Sorting of molluscs was performed at the Italian National Antarctic Museum. Taxonomic identification was performed at the Italian Antarctic National Museum (MNA, Section of Genoa) and at the British Antarctic Survey (BAS) laboratories. All living specimens were sorted under a stereomicroscope and, whenever possible, classified down to the specific level. More minute species were photographed at ESEM (Leo Stereoscan 440) facility at DISTAV. Dead shells have not been taken into account in the present study. The present molluscs dataset has been formatted in order to fulfil the standards (Darwin Core) required by the OBIS scheme (http://iobis.org/data/schema-and-metadata) according the SCAR-MarBIN Data Toolkit (available at http://www.scarmarbin.be/documents/SM-FATv1.zip). The dataset was uploaded in the ANTOBIS database (the geospatial component of SCAR-MarBIN) and added to SOMBASE (Southern Ocean Mollusc Database www.antarctica.ac.uk/sombase). SOMBASE generated initial core data system upon which SCAR’s Marine Biodiversity Information Network (SCAR-MarBIN) was built. Taxonomy was matched against the Register of Antarctic Marine Species, using the Taxon Match tool (http://www.scarmarbin.be/rams.php?p=match). Data from both the RV “Italica” and the RV “Tangaroa” (“BioRoss”, TAN0402) voyages were published in Schiaparelli et al. (2006). A detailed analysis of the distribution of mollusc species sampled by the Rauschert dredge as well as the illustration of all new records for the Ross Sea is in Ghiglione et al. (submitted). The dataflow is illustrated in Figure 1. This dataset lists the species that have been collected by deploying for the first time a Rauschert dredge in the Ross Sea (Rehm et al. 2006). Samples were obtained during the Austral summer 2004 in the framework of the 19th PNRA Antarctic expedition, on board the R/V “Italica”. The study area was the continental shelf along the latitudinal transect comprised between Cape Adare (~71°S) and Terra Nova Bay (~75°S). On the whole,eighteen stations, comprised between 84 and 515m of depth, were sampled. Sampling activities were done in four main areas of the Ross Sea: Cape Adare, Cape Hallett, Coulman Island, Cape Russell (Fig 2). The eighteen Rauschert dredge samples were obtained at Cape Adare (five sampling sites: A1, A2, A3, A4, A5), at Cape Hallett (seven sampling sites: H out 1, H out 2, H out 4, H in 2, H in 3; H in 4, H in 5), at Coulmann Island (two sites: C1, C2) and at Cape Russell (four sites: SMN, R2, R3, R4) (Rehm et al. 2006). Specimens were classified at the lowest possible taxonomic level. A 18% of species were classified at the or above the generic level due to an uncertainty about their status. The same was for another 6% of species that potentially represent new species. Although these taxa will require further studies (e.g. morphological and genetic, currently underway) these have been included in this dataset as they could be clearly distinguished during sorting activities and were therefore considered as morphospecies. During all the phases of sorting, classification and storage of samples at the Italian National Antarctic Museum, quality controls and data cleaning have been undertaken at various steps in order to produce quality data and make consistent cross-references between the database and samples' labels. The MNA uses an SQL-based database (Specify 6) to manage its collections and link all the data (photos, sequences, etc.) to the physical samples. Georeferencing on board the RV "Italica" is based on TCP/IP protocols and NetNav2000 and NetNav WEB systems. Latitudinal Gradient Program (LGP) R/V "Italica" voyage 2004 - Mollusca - Rauschert Dredge Stefano Schiaparelli contentProvider This study is part of the Project 2002/8.6 (“The coastal ecosystem of Victoria Land Coast: distribution and structure along a latitudinal gradient”) and of the Project 2010/A1.10 (Barcoding of Antarctic Marine Biodiversity, BAMBi) funded by the Italian National Antarctic Research Program (PNRA). Vouchers are maintained at the Italian National Antarctic Museum (MNA), Section of Genoa. This dataset lists the species that have been collected by deploying for the first time a Rauschert dredge in the Ross Sea (Rehm et al. 2006). Samples were obtained during the Austral summer 2004 in the framework of the 19th PNRA Antarctic expedition, on board the R/V “Italica”. The study area was the continental shelf along the latitudinal transect comprised between Cape Adare (~71°S) and Terra Nova Bay (~75°S). The Rauschert dredge was deployed in its ‘standard’ structure, i.e. having a mesh size of 500µm and with an opening of 0.5 m (Lörz et al, 1999). The dredge has been towed at a mean velocity of 1 knot to collect benthic samples at eighteen stations, comprised between 84 and 515m of depth. More details about sampling stations are reported in Rehm et al. (2006). In the past decade, the Ross Sea has been the area studied by the Latitudinal Gradient Program (LGP; www.lgp.aq) which aimed at: i) understanding the complex ecosystems that exist along the Victoria Land coast; and ii) determining the effects of environmental change on these ecosystems; iii) maximising the transfer of information and ideas, by utilising joint logistic facilities. To achieve these targets, two temporally parallel research voyages took place during the Austral summer 2004: one on board the Italian RV “Italica” and one on board the RV “Tangaroa” (“BioRoss” voyage, TAN0402) organized, respectively, by NIWA (National Institute of Water and Atmospheric Research, Wellington) and PNRA (Antarctic National Research Project). In the field, samples were collected by using a Rauschert dredge with a mesh size of 500μm. Samples were fixed on board in precooled Ethanol in order to have material suitable for genetic studies. Sorting and classification was performed at the Italian National Antarctic Museum (MNA), Section of Genoa, where all the samples were acquired as permanent vouchers. The digital and SEM images of the mollusc species studied will be made available through the ANTABIF Antarctic Field Guide Project. The LGP contributed to the SCAR biology programme Evolution and Biodiversity in the Antarctic (EBA) and now to the SCAR programme State of the Antarctic Ecosystem (AntEco). The dataflow is illustrated in Figure 1.
