The Alph River is a small river in Antarctica, running into Walcott Bay, Victoria Land. It is in an ice-free region at the west of the Koettlitz Glacier , Scott Coast . The Alph emerges from Trough Lake and flows through Walcott Lake , Howchin Lake , and Alph Lake .
Tidewater glacier on the Antarctic coast. There are many glaciers in the Antarctic.This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice.
The Antarctic Ice Sheet is drained to the sea by several ice streams. The largest in East Antarctica is Lambert Glacier.In West Antarctica the large Pine Island and Thwaites Glaciers are currently the most out of balance, with a total net mass loss of 85 gigatonnes (84 billion long tons; 94 billion short tons) per year measured in 2006.
An icefall feeding into the Lambert Glacier, Antarctica Lambert Glacier is a major glacier in East Antarctica.At about 80 km (50 mi) wide, over 400 km (250 mi) long, and about 2,500 m (8,200 ft) deep, it is the world's largest glacier.
The Henriksen Nunataks (coordinates: 71°30′S 9°0′E) are a group of scattered nunataks about 10 nautical miles (20 km) north of the Kurze Mountains in Queen Maud Land, Antarctica. They were plotted from air photos by the Third German Antarctic Expedition (1938–39), mapped from surveys and air photos by the Sixth Norwegian Antarctic ...
Using satellite observations and ice-penetrating radar, scientists are now getting a glimpse of Antarctica's lost world. Ancient landscape formed by rivers revealed deep under Antarctic ice Skip ...
Satellite image of subglacial Lake Vostok in Antarctica. Image credit: NASA. A subglacial lake is a lake that is found under a glacier, typically beneath an ice cap or ice sheet. Subglacial lakes form at the boundary between ice and the underlying bedrock, where liquid water can exist above the lower melting point of ice under high pressure.
McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999 The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross
