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). WebJun 28, 2005 · This paper presents results from a model study of the interannual variability of high salinity shelf water (HSSW) properties in the Ross Sea. Salinity and potential temperature of HSSW formed in the western Ross Sea show oscillatory behaviour at periods of 5–6 and 9 years superimposed on long-term fluctuations. While the shorter oscillations …
