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). WebApr 18, 2024 · The low salinity shelf outflow directly enters the upper estuarine loop, and the shelf seas farther east, the East Siberian and Chukchi Seas, almost exclusively feed the upper loop. The waters on the shelves are supplied by river runoff and also by a more saline water mass that provides the saline mixing end member.
