The Scientific Committee on Antarctic Research has just published what it calls the most thorough audit of marine life in the Antarctic Ocean.
The new Biogeographic Atlas of the Southern Ocean records more than 9,000 species and was created with the expertise of 147 leading marine biologists and oceanographers from 22 countries. It's the first such undertaking in the region since 1969, when the American Society of Geography published its Antarctic Map Folio series.
Following are samples of photographs from the publication.
Shown here, the Antarctic sea anemone, Hormathia lacunifera, photographed from the eastern side of the Antarctic Peninsula.
