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 This updates the well-known and useful but largely outdated Hedgpeth 1969’s Folio on “Distribution of selected groups of marine invertebrates in waters south of 35°S latitude” in the Antarctic Map Folio Series (American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.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 200 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

The “Biogeographic Atlas of the Southern Ocean” is a legacy of the International Polar Year 2007-2009 ( and of the Census of Marine Life 2000-2010 (, contributed by the Census of Antarctic Marine Life ( and the SCAR Marine Biodiversity Information Network (; The “Biogeographic Atlas” is a contribution to the SCAR programmes Ant-ECO (State of the Antarctic Ecosystem) and AnT-ERA (Antarctic Thresholds- Ecosystem Resilience and Adaptation) ( The Census of Marine Life, was an ambitious ten-year long international project that was to examine the world’s oceans and log the occurrence and demise of marine species. Its principal objective was to assess the state of marine biodiversity at the start of the 21st century to enable predictions to be made about what species might inhabit oceans in the future. By supporting scientific coordination, rather than putting ships in the water, the Foundation leveraged over USD 650 million in total outlays. The Census ran until a final meeting in October 2010 in the Royal Society in London at which outcomes from the six ocean realms under study were presented. In total, some 2700 scientists from 80 nations participated in the Census, undertaking 540 research expeditions and producing over 2600 publications. The ocean realm “Ice Ocean; Arctic and Antarctic” was the responsibility of two projects – Arctic Ocean Diversity (ArcOD) for the north of the globe, and the Census of Antarctic Marine Life (CAML) for the south. Both projects worked closely together and engaged in a number of joint initiatives. CAML started its activities mid-way through the Census, in 2005, following a deci- sion to hold a third International Polar Year (IPY) in 2007–2009. The Scientific Committee on Antarctic Research (SCAR) accepted a proposal from its Life Sciences committee that CAML should go ahead as one of fifteen biological projects to be undertaken in Antarctica during the IPY; in the event CAML turned out to be the largest of them. A key element in CAML’s success as a project was its close association with SCAR’s Marine Biodiversity Information Network (SCAR-MarBIN, www., a data portal initiated by the Royal Belgian Institute of Natural Sciences in Brussels, implemented by the Belgian Biodiversity Platform and supported financially by the Belgian Science Policy Office. It was accepted by SCAR as the main repository for marine biodiversity data in 2005. SCAR- MarBIN became CAML’s database.
