Deschanel Peak
Deschanel Peak () is the summit of an isolated, partly ice-covered mountain, high, rising from the south part of the glacier close southeast of Cape Berteaux on the west coast of the Antarctic Peninsula. The approved name derives from "Sommet Deschanel" given by J.B. Charcot, leader of the French Antarctic Expedition The French Antarctic Expedition is any of several French expeditions in Antarctica. 1837–1840 In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' alo ..., in January 1909.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...

Cape Berteaux
Mikkelsen Bay () is a bay, wide at its mouth and indenting , entered between Bertrand Ice Piedmont and Cape Berteaux along the west coast of Graham Land, Antarctica. Location Mikkelsen Bay is in the east of the larger Marguerite Bay in Graham Land on the Fallières Coast of the Antarctic Peninsula. It is south of Rymill Bay and the Bertrand Ice Piedmont, southwest of the Hadley Upland, west of the Godfrey Upland and north of the Hariot Glacier. Clarke Glacier flows into the southeast corner of the bay. Other features of the coast include Moraine Cove, Pavie Ridge, Dee Ice Piedmont, Doggo Defile, Baudin Peaks and Cape Berteaux. Islands in the bay, or to the west of the bay, include from east to west, Query Island, Keyhole Island, the Terra Firma Islands, Compass Island and the Flyspot Rocks. Exploration and name Mikkelsen Bay was first seen from a distance in 1909 by the French Antarctic Expedition (FrAE) under Jean-Baptiste Charcot, but was not recognized as a large ba ...

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martin 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 in Antarctica, clima ...

French Antarctic Expedition, 1908–10
The French Antarctic Expedition is any of several France, French expeditions in Antarctica. 1837–1840 In 1837, during an 1837–1840 Jules Dumont d'Urville#Second voyage of Astrolabe, expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this expedition, Dumont d'Urville team performed the first experiments to determine the approximate position of the South magnetic pole, and landed on Débarquement Rock in the Géologie Archipelago, () just 4 km from the mainland, where he took mineral and animal samples. On his return to France in 1840 he was made rear admiral. 1904–1907 Jean-Baptiste Charcot was appointed leader of a 1904–1907 French Antarctic Expedition, aboard the ship ''Français'', exploring the west coast of Graham Land portion of the Antarctic Peninsula. The expedition reached ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Graham Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mou ...
