Extended Data Fig. 7: Latitude–depth sections across each Southern Ocean basin showing contraction of densest waters.
From: Recent reduced abyssal overturning and ventilation in the Australian Antarctic Basin
Thick lines map contraction of densest water masses where blue-yellow-red colours track depths of each isoline during select years from 1990 to 2020 (isoline density indicated in each panel and colour scale in middle row). Moving eastwards, top row shows A12 and I06S across the Weddell–Enderby Basin, middle row shows I09S across the Australian Antarctic Basin, and bottom row shows P16 and P18 across the Amundsen-Bellingshausen Basin. Central map shows circum-Antarctic coverage of the repeat hydrographic sections.
