This dataset contains relative abundance (%) of diatom species, and includes the Eucampia antarctica terminal/intercalary valve ratio (Eucampia index), biogenic silica and Si/Al values from core TAN1302-44, which was collected from the WEGA channel on the continental slope, offshore Adélie Land, Eas...
