WebOur results show the evidence of an overflow of dense water, originated on the continental shelf, on the shelf-break. This supercold water signal is found on the continental slope down to 1200 m depth. The shape of this tongue of modified ISW, whose thickness reaches up to 100 m, is very narrow, suggesting that the overflow occurs in very ...

WebDec 28, 2024 · The offshore edge of the relatively shallow continental shelf, the shelf break, is the boundary between the cooler and fresher water on the continental shelf (shelf water) and the warmer and saltier water offshore (slope water). This water boundary at the shelf break is thought to support high chlorophyll concentrations. karen tweed billy and bob"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. lawrence taylor attorney portland oregonWebWe also describe an additional cross-shelf intrusion of ring water in September 2014 to demonstrate that the occurrence of high-salinity waters extending across the continental shelf is rare.
