Fig. 1: Chlorophyll and sea surface temperature in the study area.

a and b, Maps of chlorophyll a concentration c. Sea Surface Temperature (SST) and d. Sea Level Anomaly (SLA) for Southern Ocean waters south of Australia. The diamonds represent the Cold Core eddy station (CCE), the Subantarctic zone station (SAZ) and the Southern Ocean Time Series station (SOTS) and the solid black line represents the Triaxus tow (Supplementary Fig. 1). The chlorophyll a satellite data represents a monthly average for March 2016. The SST data are for 3 April 2016 and SLA data are for 25 March 2016. In b and c the contours lines are SST.
