SCAR Biogeographic Atlas of the Southern Ocean - macroalgae - Data

Antarctic OBIS Open in mapper Explore occurrences

This dataset represents a literature study on the distribution of marcoalgae 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 This updates the well-known and useful but largely outdated biogeographic Folios of the Antarctic Map Folio Series (American Geographical Society). This dataset contains species records of macro algae from the Southern Ocean (locations below 40°S) reported in 72 publications published between 1890 and 2011.
