Glacier Morphology
Glacier morphology, or the form a glacier takes, is influenced by temperature, precipitation, topography, and other factors. The goal of glacial morphology is to gain a better understanding of glaciated landscapes and the way they are shaped. Types of glaciers can range from massive ice sheets, such as the Greenland ice sheet, to small cirque glaciers found perched on mountain tops. Glaciers can be grouped into two main categories: * Ice flow is constrained by the underlying bedrock topography * Ice flow is unrestricted by surrounding topography Unconstrained Glaciers Ice sheets and ice caps Ice sheets and ice caps cover the largest areas of land in comparison to other glaciers, and their ice is unconstrained by the underlying topography. They are the largest glacial ice formations and hold the vast majority of the world's fresh water. Ice sheets Ice sheets are the largest form of glacial formation. They are continent sized ice masses that span areas over . They are dome s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Johns Range
Saint Johns Range () is a crescent-shaped mountain range about long, in Victoria Land. It is bounded on the north by the Cotton, Miller and Debenham Glaciers, and on the south by Victoria Valley and the Victoria Upper Glacier, Victoria Upper and Victoria Lower Glaciers. Its eastern end is formed by a spur called Lizards Foot. Named by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition, 1956–58, which surveyed peaks in the range in 1957. Named for St John's College, Cambridge, St. John's College at Cambridge, England, with which several members of the Terra Nova Expedition, British Antarctic Expedition (1910–13) were associated during the writing of their scientific reports, and in association with the adjacent Gonville and Caius Range. Kuivinen Ridge Kuivinen Ridge () is a transverse ridge extending southwest–northeast across the Saint Johns Range between an unnamed glacier and the Ringer Glacier in Victoria Land.

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson. In 1979, scientists discovered a group of 309 meteorites in Antarctica, some of which were found near the Allan Hills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Harker
Mount Harker is a mountain peak located east of Willis Glacier in the Saint Johns Range, Victoria Land, Antarctica. The mountain was first mapped by the Terra Nova Expedition (1910–1913) led by Robert Falcon Scott. The mountain is named for Alfred Harker (1859–1939), an English geologist who specialised in petrology Petrology () is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together ... and petrography.

Debenham Glacier
Wilson Piedmont Glacier () is a large piedmont glacier extending from Granite Harbour to Marble Point on the coast of Victoria Land. Scheuren Stream takes meltwater from the glacier into the Bay of Sails, while South Stream flows southeastward to Bernacchi Bay. Discovered by the ''Discovery'' expedition, 1901–04. The British Antarctic Expedition, 1910–13, named the feature for Dr. Edward A. Wilson, surgeon and artist with Scott's first expedition and chief of the scientific staff with the second. Wilson lost his life on the way back from the South Pole with Scott. See also *Ball Stream *King Pin King Pin () is a nunatak, high, rising above the Wilson Piedmont Glacier, Antarctica, about midway between Mount Doorly and Hogback Hill.

Victoria University Of Wellington Antarctic Expedition
The Antarctic Research Centre (ARC) is part of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. Its mission is to research "Antarctic climate history and processes, and their influence on the global climate system. The current director of the Antarctic Research Centre is Associate Professor Robert McKay. Directors * 1972 - 2007: Professor Peter Barrett * 2008 - 2016: Professor Tim Naish * 2017 - 2019: Professor Andrew Mackintosh * 2020 - Present: Professor Robert McKay History In December 1957, geology students Barrie McKelvey and Peter Webb along with biologist Ron Balham conducted an expedition to the then unexplored McMurdo Dry Valleys via the Royal New Zealand Navy Antarctic support ship HMNZS ''Endeavour''. This expedition formed the basic for the annual Victoria University of Wellington Antarctic Expeditions, which continue to the present day. Since this first expedition, over 400 staff and students have travelled to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
