During and after glacial retreat, the rise of sea level and the action of tidal and storm currents marked the start of an erosional episode on the bank that continues today. Water depth is 73 meters. We have,'explored models involving both depth and temperature. The Seychelles Bank encompasses an area of 31,000 square km in the Indian Ocean. Updates? The cross-bank bottom topography rises steeply with a slope of about 0.01 from 1000 m on the slope to 100 m at the shelf break, increases slowly with a slope of 0.0004 to 40 m over a distance of about 150 km on the top of the Bank, and then decreases rapidly with a slope of about 0.03 to a depth of 300 m in the deep basin just north of GB. and 66 deg. The winnowing and redistribution of glacial sediment has formed modern habitats, which are altered as geological processes continue to operate. 1.

The edges of the bank plunge down to great depths of about 13,000 ft. 6. Therefore, the gravel may be essential for their survival and recruitment to the fishery. The giant sea scallop (Placopecten magellanicus) metapopulation on Georges Bank (GB) in the northwest Atlantic constitutes an economically important fishery, which is sustained by retention of planktonic larvae that are advected among three subpopulations.Dispersal of GB scallop larvae spawned in the fall is known to be sensitive to climate-related variability in the currents.

As in the COST wells, dolomite and anhydrite interbeds are common below about 12,000 feet (figure 4). In 1994 large areas of Georges Bank were closed indefinitely to ground fishing in order to protect depleted stocks of cod, haddock, and yellowtail flounder.
