Weddell Sea

(wĕd`əl), arm of the Atlantic Ocean, W Antarctica, SE of South America, bordered by the Antarctic Peninsula and Coats Land. The vast Ronne and Filchner ice shelves are at the head of the sea. Named for James Weddell, a British navigator who claimed to have discovered the sea in 1823, it was investigated by the Scottish explorer William BruceBruce, William Speirs
, 1867–1921, Scottish explorer and authority on the polar regions. He first went to the Antarctic as ship's surgeon in 1892 and later did survey work in Franz Josef Land and oceanographic work in the Arctic Ocean.

 from 1902 to 1904. It was studied fully during the International Geophysical Year (1957–58) and has since been a site of continuing investigation.

Weddell Sea

 

a marginal sea indenting the coastline of Antarctica. It lies between the Antarctic Peninsula on the west and Coats Land on the east, and its southern shores form the edges of the Ronne and Filchner ice shelves. The Weddell Sea has an area of 2,796,400 sq km. Prevailing depths are 3,000 m, and maximum depths exceed 4,500 m in the northern part. The southern and southwestern parts are shallow, with depths of up to 500 m. Much of the sea is covered throughout the year by pack ice; there are many icebergs.

On the coast of the Weddell Sea are located the British Antarctic station at Halley Bay and four Argentine stations, three of which are on the Antarctic Peninsula. In late 1975 the Soviet seasonal station Druzhnaia was established on the southern shore of the sea. The Weddell Sea was first entered in 1823 by an English expedition led by J. Weddell, who named it George IV Sea. In 1900 the sea was renamed in honor of Weddell.

He said: "Much of our time has been spent along the edge of the Larsen-C Ice Shelf where science operations involved repeated oceanographic measurements of the water column adjacent to the ice shelf to determine the volume and rate of fresh, cold ice-shelf water formation due to the melting of the ice shelf base and the intrusion of relatively warmer water masses from the Weddell Sea under the ice shelf.
The search team - led by Prof Julian Dowdeswell - cracked through part of the 17,000 sq mile Larson C ice shelf in the Weddell Sea.

A block of ice the size of Delaware broke away from the Larsen C ice shelf and is now floating the Weddell Sea. overtime, this massive iceberg will break into smaller ones, further enhancing a spectacle that is already sparking a surge in iceberg-watching cruises, like those of French line Ponant, which uses advanced sonar for tracking t keep the ship in perfect position without dropping anchor, so as not to disturb the ocean floor.
"I was very honoured he did that, and Sir Ranulph Fiennes gave me a quote for the cover, and I've joked I'm going to have to get the quotes tattooed on my forehead!" The photos Sue took for the book are also being used in a campaign to protect the Weddell Sea, where she spent a lot of her time.

Antarctic scientists are drawing up the technical plans for marine protected areas in the Antarctic Ocean, one of which is expected to cover around 1.8 million square kilometers in the Weddell Sea. The final decision will be taken by the CCAMLR in October 2018, when it convenes in Hobart, Tasmania.
