Thurston Glacier is a glacier about 28 km (17 mi) long which drains the south-eastern slopes of Mount Siple on Siple Island. The glacier trends eastward and then east-north-eastward to reach the northern shore of the island. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy aerial photography, 1959–65.

Discovery and naming

The glacier was named by the Advisory Committee on Antarctic Names (US-ACAN) for Thomas R. Thurston, a United States Antarctic Research Program (USARP) meteorologist at Byrd Station in 1965. [1]

Important Bird Area

A 293 ha site, comprising the marine area and fast ice that forms near the terminus of the glacier, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 3,000 emperor penguins, estimated from 2009 satellite imagery. [2]

The Amundsen Sea, an arm of the Southern Ocean off Marie Byrd Land in western Antarctica, lies between Cape Flying Fish to the east and Cape Dart on Siple Island to the west. Cape Flying Fish marks the boundary between the Amundsen Sea and the Bellingshausen Sea. West of Cape Dart there is no named marginal sea of the Southern Ocean between the Amundsen and Ross Seas. The Norwegian expedition of 1928–1929 under Captain Nils Larsen named the body of water for the Norwegian polar explorer Roald Amundsen while exploring this area in February 1929.

Thurston Island Antarctic island

Thurston Island is an ice-covered, glacially dissected island, 215 km (134 mi) long, 90 km (56 mi) wide and 15,700 km2 (6,062 sq mi) in area, lying a short way off the northwest end of Ellsworth Land, Antarctica. It is the third largest island of Antarctica, after Alexander Island and Berkner Island.

Several large islands are partially or wholly embedded in the ice shelf, pinning the calving front.

Stancomb-Wills Glacier Glacierof Antarctica

The Stancomb-Wills Glacier is a large glacier that debouches into the eastern Weddell Sea southward of Lyddan Island. The glacier was discovered in the course of the U.S. Navy LC-130 plane flight over the coast on November 5, 1967, and was plotted by the United States Geological Survey (USGS) from photographs obtained at that time. The name was applied by the Advisory Committee on Antarctic Names (US-ACAN) in 1969.

Sikorski Glacier Glacier of Antarctica

The Sikorski Glacier is a small glacier in the north-eastern part of the Noville Peninsula, Thurston Island, Ellsworth Land, Antarctica. It flows north-east to the Bellingshausen Sea between Mount Palmer and Mount Feury. It was first roughly delineated from aerial photos taken by the USN's Operation Highjump in 1946–47. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for Stephen Sikorski, electronics technician on USS Glacier, who assisted in setting up an automatic weather station on Thurston Island during the USN's Bellingshausen Sea Expedition in February 1960.

It was named by the Advisory Committee on Antarctic Names after JoAnn Isbrecht of the United States Geological Survey (USGS), Flagstaff, Arizona, a satellite image processing specialist who was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.

Acosta Glacier

Acosta Glacier is a glacier about 2 miles (3 km) long flowing north from Thurston Island just east of Dyer Point in Antarctica. It was named by the Advisory Committee on Antarctic Names (US-ACAN) after Alex V. Acosta of the United States Geological Survey (usgs) in Flagstaff, Arizona. He is a computer and graphic specialist, and was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer satellite image maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.

The Blob is a fairly conspicuous, mound-shaped knoll that is almost completely snow-covered, standing midway between Thurston Glacier and Armour Inlet on the north coast of Siple Island. This feature was first plotted by United States Geological Survey (USGS) from air photos taken by U.S. Navy Operation Highjump in January 1947. The descriptive name was suggested by a member of the Advisory Committee on Antarctic Names (US-ACAN) staff on the basis of the appearance of the feature in the aerial photographs.
