WebSep 21, 2024 · The geostrophic stress has been overlooked in the dynamics of shelf break fronts, which have a depth of O (100 m) or deeper. In related research, Moffat and Lentz ( 2012) discussed a similar but shallower overturning adjacent to the coast with a depth of approximately 15 m. WebJan 18, 2024 · The coastal ocean is a body of water that connects the coast to the shelf break. As a highly dynamic region lying on the outer edge of a continent, the coastal ocean's various processes interactively influence its physical, chemical, and biological dynamics. To promote a holistic understanding of the coastal ocean and its influences, we collected …

Shelf sea exchange with the ocean - Coastal Wiki

"Shelf seas" refers to the ocean waters on the continental shelf. Their motion is controlled by the combined influences of the tides, wind-forcing and brackish water formed from river inflows (Regions of Freshwater Influence). These regions can often be biologically highly productive due to mixing caused by the shallower waters and the enhanced current speeds. Despite covering only about 8% of Earth's ocean surface area, shelf seas support 15–20% of global primary productivity. WebAlan R.
