A glacial terminus Satellite view of changing glacier termini in the Bhutan-Himalaya, showing glacial lakes formed by the retreating termini on the surface of the debris-covered glaciers over the last several decades. A glacier terminus, toe, or snout, is the end of a glacier at any given point in time.
In case of the termination of the last glacial cycle, the retreat of continental ice sheets in the Northern hemisphere began about 20,000 calendar years ago. By about 7,000 calendar years ago, a small ice cap on Baffin Island was all that was left of the great Laurentide Ice Sheet that had once covered northern North America. In Antarctica, the ...
Ice worms (also written as ice-worms or iceworms, or also called glacial or glacier worms) are enchytraeid annelids of the genus Mesenchytraeus. The majority of the species in the genus are abundant in gravel beds or the banks of riverine habitats, [ 2 ] [ 3 ] but the best-known members of the genus are found in glacial ice.
During the Last Glacial Maximum, much of the world was cold, dry, and inhospitable, with frequent storms and a dust-laden atmosphere. The dustiness of the atmosphere is a prominent feature in ice cores; dust levels were as much as 20 to 25 times greater than they are in the present.
Aerial view of the glacier, taken two weeks before the 2004 rupture. The Perito Moreno (Spanish: Glaciar Perito Moreno), Francisco Gormaz or Bismarck Glacier [1] is a glacier located in Los Glaciares National Park in southwest Santa Cruz Province, Argentina, and originated in the Magallanes Region in Chile, being also part of the Bernardo O'Higgins National Park.
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. [1] The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. [ 2 ]
Multiple erratics on the terminal moraine of the Okanogan Lobe. The Cascade Mountains are in the background.. The term "erratic" is commonly used to refer to erratic blocks, which geologist Archibald Geikie describes as: "large masses of rock, often as big as a house, that have been transported by glacier ice, and have been lodged in a prominent position in the glacier valleys or have been ...
Satellite image of kettle lakes in Yamal Peninsula (Northern Siberia), adjacent to the Gulf of Ob (right). The lake colors indicate amounts of sediment or depth. A kettle (also known as a kettle hole, kettlehole, or pothole) is a depression or hole in an outwash plain formed by retreating glaciers or draining floodwaters.
