Fig. 6: Comparison of Ross Gyre forcing and Amundsen continental shelf break winds that drive onshore transport variability.
From: Ross Gyre variability modulates oceanic heat supply toward the West Antarctic continental shelf
a 2018 minus 2014 sea level pressure, with a green contour denoting the mean gyre boundary and black lines marking bathymetry in 1000 m intervals with the 1000 m isobath plotted thicker to indicate the approximate location of the Antarctic Slope Front. A purple box denotes the region of maximum negative wind stress curl that forces the gyre and a yellow box marks the offshore heat reservoir adjacent to the Amundsen. b Monthly time series of zonal wind stress anomaly (yellow) near the Amundsen continental slope (yellow box in a) and ocean surface stress curl (purple) averaged over the gyre forcing region (purple box in a). c Time series of upper ocean temperature in the offshore reservoir (yellow box in a) with isopycnals overlaid in black and the 27.9 γn surface highlighted in bold.
