Dense shelf water formation along the south‐west Australian inner shelf

摘要: [1] Hydrological data from a repeated cross-shore transect obtained using Teledyne Webb Research Slocum Electric gliders offshore Two Rocks in south-western Australia over 13 months are presented. The revealed that formation of dense water inshore and its transport across the shelf as near bed gravity current (defined Dense Shelf Water Cascade, DSWC) was regular occurrence, particularly during autumn winter months. In autumn, is mainly formed through changes salinity resulting evaporation, whilst winter; temperature change surface cooling dominant factor. mean wind speeds also decrease transition autumn. speed DSWC estimated to be 0.01–0.02 m s−1, similar measured other selected regions globally. significant component alongshore wind-driven transport.
