Fig. 3: Correlation maps of satellite variables.
From: A chlorophyll halo over Maud Rise in the Southern Ocean

Correlation maps between a SST and Chl-a concentration and b between SST and SSH. Isobaths, plotted as black solid contours, are drawn every 500 m. The 3500 m isobath is drawn in blue. Hatched areas show significant correlations (p < 0.05). See Figure S13 for more information on the slope of the regression.
