Fig. 3: Ocean temperature anomalies associated with contracted and expanded gyre states.
From: Ross Gyre variability modulates oceanic heat supply toward the West Antarctic continental shelf
Map of the annual mean temperature anomaly (relative to the 2013-2018 mean) on the γn = 27.9 kg m−3 surface for a 2014 and c 2018, reflecting the contracted and expanded gyre states, respectively. In both panels, the green contour represents the mean gyre boundary for that year, while black contours mark bathymetry in 1000 m intervals with the 1000 m isobath plotted thicker to indicate the approximate location of the Antarctic Slope Front. The dashed black line indicates a meridional transect moving offshore from the Amundsen Sea continental shelf (along 105∘W). The annual mean temperature anomaly in the top 1400 m on this transect is plotted for b 2014 and d 2018. Black contours denote isopycnals for each year, with the 27.9 γn surface highlighted in bold.
