Weyerhaeuser Glacier
Weyerhaeuser Glacier () is a large glacier flowing north into Mercator Ice Piedmont close west of Mobiloil Inlet, on the east coast of Antarctic Peninsula. This glacier lies in the area first explored from the air by Sir Hubert Wilkins in 1928 and Lincoln Ellsworth in 1935, but it was first clearly delineated in aerial photographs taken by the United States Antarctic Service (USAS) in 1940. The glacier was resighted in 1947 by the Ronne Antarctic Research Expedition (RARE) under Ronne. He named it for F. K. Weyerhaeuser, of the Weyerhaeuser Timber Co., who contributed lumber and insulating material to the expedition.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Mercator Ice Piedmont
Mercator Ice Piedmont () is a gently-sloping ice piedmont at the head of Mobiloil Inlet, formed by the confluence of the Gibbs, Lammers, Cole and Weyerhaeuser Glaciers in eastern Graham Land, Antarctica. The feature was first photographed from the air by Lincoln Ellsworth in November 1935, and was plotted from these photos by W.L.G. Joerg as the lower end of a "major valley depression" along the coast. It was first seen from the ground by Finn Ronne and Carl R. Eklund of the United States Antarctic Service, 1939–41, which also obtained air photos. The ice piedmont was surveyed by the Falkland Islands Dependencies Survey in December 1958, and was named by the UK Antarctic Place-Names Committee after Flemish mathematician and geographer Gerardus Mercator, the originator, in 1568, of the map projection which bears his name.

Mobiloil Inlet
Mobiloil Inlet () is an ice-filled inlet, nurtured by several northeast and east flowing glaciers, lying between the Rock Pile Peaks and Hollick-Kenyon Peninsula along the east coast of the Antarctic Peninsula. It was discovered by Sir Hubert Wilkins in a flight on December 20, 1928, and named by him after a product of the Vacuum Oil Company of Australia.

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Sir Hubert Wilkins
Sir George Hubert Wilkins MC & Bar (31 October 188830 November 1958), commonly referred to as Captain Wilkins, was an Australian polar explorer, ornithologist, pilot, soldier, geographer and photographer. He was awarded the Military Cross after he assumed command of a group of American soldiers who had lost their officers during the Battle of the Hindenburg Line, and became the only official Australian photographer from any war to receive a combat medal. He narrowly failed in an attempt to be the first to cross under the North Pole in a submarine, but was able to prove that submarines were capable of operating beneath the polar ice cap, thereby paving the way for future successful missions. The US Navy later took his ashes to the North Pole aboard the submarine USS ''Skate'' on 17 March 1959. Early life Hubert Wilkins was a native of Mount Bryan East, South Australia, the last of 13 children in a family of pioneer settlers and sheep farmers. He was born at Mount Bryan East, ...

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

United States Antarctic Service
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Ronne Antarctic Research Expedition
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica. Background Finn Ronne led the RARE which was the final privately sponsored expedition from the United States and explored and mapped the last unknown coastline on earth and determined that the Weddell Sea and the Ross Sea were not connected. The expedition included Isaac Schlossbach, as second in command, who was to have Cape Schlossbach named after him. The expedition, based out of Stonington Island was the first to take women to over-winter. Ronne's wife, Edith Ronne was correspondent for the North American Newspaper Alliance for expedition and the chief pilot Darlington took his wife.

Weyerhaeuser Timber Co
Weyerhaeuser () is an American timberland company which owns nearly of timberlands in the U.S., and manages an additional of timberlands under long-term licenses in Canada. The company also manufactures wood products. It operates as a real estate investment trust. History In 1904, after years of successful Mississippi River-based lumber and mill operations with Frederick Denkmann and others, Frederick Weyerhäuser moved west to fresh timber areas and founded the Weyerhäuser Timber Company. Fifteen partners and of Washington timberland were involved in the founding, and the land was purchased from James J. Hill of the Great Northern Railway. In 1929, the company built what was then the world's largest sawmill in Longview, Washington. Weyerhaeuser's pulp mill in Longview, which began production in 1931, sustained the company financially during the Great Depression. In 1959, the company eliminated the word "Timber" from its name to better reflect its operations. In 1965, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
