| Summary: | a salinity criterion corresponding to the base of the and is 34.40 on average. Antarctic Surface Water has Antarctica are examined and their spatial distributions are at the Antarctic continental slope, the water masses near Bellingshausen-Amundsen sector (between 63' and 155'W) along break between Shelf Water and Antarctic Slope Front Water. Circumpolar Deep Water and Antarctic Slope Front Water, and Circumpolar Deep Water with low-salinity Shelf Water, is defined as water over the Antarctic shelf regime with described. Antarctic Surface Water over the Antarctic shelf diapycnal mixing of low-salinity Antarctic Slope Front Water distinguished from high-salinity Shelf Water by the maximum Front Water, produced by isopycnal mixing of Lower greater than the maximum density of Lower Circumpolar Deep High-salinity Antarctic Slope Front Water, produced by is found wherever Antarctic Slope Front Water exists. To isopleths, shallow and deep references are required for the kg m-3). Antarctic Slope Front Water is characterized by observed everywhere around Antarctica except in the obtain westward geostrophic flows associated with the V-shape potential density of Lower Circumpolar Deep Water ([] = 27.87 potential temperature between -1.7'C and about 0.2'C, and potential temperature minimum layer of Antarctic Surface referred to as low-salinity Antarctic Slope Front Water. regime is distinguished from underlying other water masses by salinities less than the cut-off salinity. Shelf Water is salinity greater than the cut-off salinity and potential salinity greater than the cut-off salinity. Antarctic Slope shelf regime and the oceanic regime, respectively. temperature less than -1.7'C. Low-salinity Shelf Water is the Antarctic continental slope. The presence of different The former is referred to as the Antarctic Slope Front, which the other (sloping down toward the north) over the shelf To better understand and describe the Antarctic Slope Front toward Antarctica) over the continental slope between Lower V-shaped double meridional gradients: one (sloping down varies with space and time from approximately 34.35 to 34.45, Water (go = 27.87 kg m-1). Antarctic Slope Front Water is Water in the neighboring oceanic regime. This salinity water masses over the Antarctic continental margin produces with high-salinity Shelf Water, is observed with densities |
