Scotia Sea

 

part of the Atlantic section of the Antarctic Ocean between South Georgia and the South Sandwich and South Orkney islands; in the west, it is linked to the Pacific Ocean by Drake Passage. The Scotia Sea has an area of more than 1.3 million sq km and depths of 5,870 m. The average surface temperature of the water varies from 6 °C to - 1 °C; the salinity is approximately 34 parts per thousand. For a considerable part of the year, the southern part of the sea is covered with drift ice. The area is commercially important for whaling. The Scotia Sea was named in 1932 in honor of the ship used by W. Bruce on his Scottish expedition to Antarctica.

Researchers at University of Cologne, Oregon State University, the Alfred-Wegener-Institute, University of Hawaii at Manoa, University of Lapland, University of New South Wales, and University of Bonn, examined two sediment cores from the Scotia Sea between Antarctica and South America that contained "iceberg-rafted debris" that had been scraped off Antarctica by moving ice and deposited via icebergs into the sea.
Washington: A powerful 7.8 magnitude undersea earthquake struck in the Scotia Sea, a remote region in the far south Atlantic near Antarctica, US earthquake monitors reported on Sunday.
The epicenter was at a depth of 10 kilometers (6.2 miles), and was near that of a 6.8 magnitude undersea earthquake that the USGS registered in the Scotia Sea some 30 hours earlier.
Major and trace element geochemistry suggest an N- to E-MORB nature for the protolith, which cannot rule-out a back- or inter-arc basin origin, like is seen in the East Scotia Sea. This data supports a model in which the back-arc YZSZ ophiolites (in the Xigaze area) were trapped in a fore-arc setting by theinception of a subduction at the back-/inter-arc ridge.
In fact, the entire Scotia Sea seems to have had the rug pulled out from underneath it.

ABSTRACT Management of the Nova Scotia sea urchin fishery includes several unusual features: one license per fishing zone, fishers increase resource yields over natural levels by controlling the sea urchin-macrophyte cycle, fishers scale fishing effort to market demand, fishers map the resource in their zones, a reference point for good resource management based on a conspicuous habitat feature, an audit of zone management success, and low ongoing input from the management agency.
