Thwaites Glacier is an unusually broad and vast Antarctic glacier located east of Mount Murphy, on the Walgreen Coast of Marie Byrd Land. It was initially sighted by polar researchers in 1940, mapped in 1959–1966 and officially named in 1967, after the late American glaciologist Fredrik T. Thwaites. [ 1][ 3] The glacier flows into Pine Island ...
The lists include outlet glaciers, valley glaciers, cirque glaciers, tidewater glaciers and ice streams. Ice streams are a type of glacier [ 5] and many of them have "glacier" in their name, e.g. Pine Island Glacier. Ice shelves are listed separately in the List of Antarctic ice shelves. For the purposes of these lists, the Antarctic is defined ...
Ice calving, also known as glacier calving or iceberg calving, is the breaking of ice chunks from the edge of a glacier. [ 1] It is a form of ice ablation or ice disruption. It is the sudden release and breaking away of a mass of ice from a glacier, iceberg, ice front, ice shelf, or crevasse. The ice that breaks away can be classified as an ...
The glacier has since had a negative mass balance trend. [20] The Juneau Icefield Research Program also has studied the mass balance of the Lemon Creek Glacier since 1953. The glacier has had an average annual balance of −0.44 m per year from 1953 to 2006, resulting in a mean loss of over 27 m of ice thickness.
In glaciology, an ice sheet, also known as a continental glacier, [ 2 ] is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km 2 (19,000 sq mi). [ 3 ] The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice sheets are bigger than ice shelves or alpine glaciers.
Wheeler Peak Glacier is a glacier situated at the base of Wheeler Peak within Great Basin National Park in the U.S. state of Nevada. [2] It is the only glacier in the state, and one of the southernmost glaciers in the United States. [3] At a height of 13,063 feet (3,982 m), Wheeler Peak is the tallest mountain in the Snake Range and the second ...
The World Glacier Monitoring Service (WGMS) was started in 1986, combining the two former services PSFG (Permanent Service on Fluctuations of Glaciers) and TTS/WGI (Temporal Technical Secretary/World Glacier Inventory). It is a service of the International Association of the Cryospheric Sciences of the International Union of Geodesy and ...
Perito Moreno Glacier. / 50.500°S 73.133°W / -50.500; -73.133. The Perito Moreno Glacier ( Spanish: Glaciar Perito Moreno) is a glacier located in Los Glaciares National Park in southwest Santa Cruz Province, Argentina, and originated in the Magallanes Region in Chile. It is one of the most important tourist attractions in the ...
