Amount of Coldest Antarctic Water Near Ocean Floor Decreasing for Decades

A layer of Antarctic Bottom Water colder than 0ºC (colors, with darkest blue areas having the thickest layer, and white none) covers the ocean floor around Antarctica (center, shaded grey).  Rates at which this layer is thinning during the study period (red numbers in meters per decade) are shown for for each deep basin (outlined by thin grey lines).  These rates are estimated using data from repeated oceanographic expeditions (ship tracks…
