WebWe finally take the median of all the combinations: temperature or salinity, NADW properties from SPG or GIN, and AABW or NADW contents. For the NADW layer, we detect the NADW core as the maximum NADW content with the extra criterion that the maximum must be larger than 80 % NADW. WebJan 1, 2024 · CDW is present around much of the Antarctic continental shelf edge except in the Weddell Sea (Dinniman et al., 2010). Mixing of CDW with locally generated waters such as AASW and high salinity shelf water creates modified CDW (MCDW) whose properties vary depending upon the mixing regime (Whitworth et al., 1998).

WebAn artificial dye, as well as temperature, is used to diagnose the flux of CDW onto the shelf. Model results for the Ross Sea show a vigorous onshore flux of oceanic water across the shelf break both at depth and at the surface as well as creation of dense water (High Salinity Shelf Water) created by coastal polynyas in the western Ross Sea. WebThe formation of High-Salinity Shelf Water (HSSW), which is the major source of Antarctic bottom water (AABW), has been observed in Terra Nova Bay (TNB) in Antarctica. We believe that a description of the spatio-temporal variation of salinity in TNB would help understand the production of HSSW in the region.
