FIGURE 1.
Map of sampling sites. Sample locations for the southern hemisphere overlaid on sea surface temperature (SST, °C; shaded) and dynamic height (m; black contours in 0.2 m intervals from -1.4 m to 1.4 m). Closed contours indicate eddies. The Agulhas Return Current (ARC) is indicated by the band of tightly spaced contours at ~40°S; south of the ARC is the Antarctic Circumpolar Current (ACC). (A) Refers to 15/02/12, (B) refers to 29/02/2012, and (C) refers to 14/03/2012.
