Flotsam Moraines
The Flotsam Moraines () are the moraines trailing northeastward from Mount Morrison, trapped in the ice eddies between Midship Glacier and ice from local mountainside glaciers, in the Prince Albert Mountains of Victoria Land, Antarctica. They were so named by a 1989–90 New Zealand Antarctic Research Program field party from association with Jetsam Moraine and because all supraglacial moraines are "floating" on the glacier ice, and drift in a manner similar to marine flotsam and jetsam In maritime law, flotsam'','' jetsam'','' lagan'','' and derelict are specific kinds of shipwreck. The words have specific nautical meanings, with legal consequences in the law of admiralty and marine salvage. A shipwreck is defined as the remai ....

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from ProvenĂ ...

Mount Morrison (Victoria Land)
Benson Glacier () is a glacier about long, draining the east part of Flight Deck Névé and continuing east between Fry Glacier and Mackay Glacier into the north part of Granite Harbour where it forms a floating tongue. Exploration and naming Benson Glacier was mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–1958), and indicated as a somewhat longer glacier including the present Midship Glacier. It was named by the party after Noel Benson, formerly professor of geology at the University of Otago, New Zealand, whose publications include a major contribution to the petrology of Victoria Land. Location The Benson Glacier forms in the northeast end of Alatna Valley in the Convoy Range and flows northeast to the south of Mount Razorback, Dotson Ridge, Flagship Mountain, Mount Davidson (Antarctica) and Mount Nesbelan, which surround Flight Deck Névé. To the south the Benson Glacier flows past Mount Morrison, Mount ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midship Glacier
Midship Glacier () is a broad flat glacier filling the bulk of Alatna Valley and having its origin on the slopes of Mount Morrison (Victoria Land), Mount Morrison to the south, in the Convoy Range, Victoria Land, Antarctica. From 1957 this ice body was considered part of Benson Glacier, however, it was determined by a 1989–90 New Zealand Antarctic Research Programme field party (led by Trevor Chinn (glaciologist), Trevor Chinn) that although it abuts against the main Benson Glacier at Jetsam Moraine, this glacier makes no contribution of ice to the Benson as its dominant ice flow is northward across its length. With the identification of Midship Glacier as a distinct feature, the application of Benson Glacier has been restricted to the ice flowing eastward from Flight Deck Névé to the terminus in Granite Harbour. The name was approved by the Advisory Committee on Antarctic Names in 1993 as recommended by the New Zealand Geographic Board. References Glaciers of Victoria L ...

Prince Albert Mountains
The Prince Albert Mountains () are a major mountain group in Antarctica over 320 km (200 mi) long. Located in Victoria Land, they run north–south between the Priestley and Ferrar glaciers. They were named for Prince Albert, the consort of the British Queen Victoria. Although they were discovered by Sir James Clark Ross on February 17, 1841, they were not first explored until the early 1900s, when British cartographers came. They were mapped and surveyed carefully by explorers from the United States and New Zealand in the 1950s and 1960s. Major peaks This range include the following mountains: Other features Other features or groups of features in the Prince Albert Mountains have been named by various survey groups and expeditions. Sheppard Rocks () is a group of rocks first mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1956–62. Named by Advisory Committee on Antarctic Names (US-ACAN) for Paul D. Sheppard, storeke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
New Zealand Antarctic Research Program
The New Zealand Antarctic Research Programme (NZARP) was a research program that operated a permanent research facility in Antarctica from 1959 to 1996. It was created by the Geophysics Division of New Zealand's Department of Scientific and Industrial Research (DSIR), originally based in Wellington. The programme promoted research in geochemistry, zoology, geology, botany, meteorology, and limnology. History NZARP began as a proposal by the New Zealand government, in 1953, for a research base in Antarctica. Its mission was to provide support for a variety of scientific fieldwork in Antarctica. Members worked as researchers, assistants, tour guides, operators, and administrators to Scott Base. Ground was broken for Scott Base on 10 January 1957. Assembly of the base began 12 January, conducted by the eight men who first assembled the base in Wellington, and was completed by 20 January. In 1959, the NZARP was established to work with the Ross Dependency Research Committee in the Ros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flotsam And Jetsam
In maritime law, flotsam'','' jetsam'','' lagan'','' and derelict are specific kinds of shipwreck. The words have specific nautical meanings, with legal consequences in the law of admiralty and marine salvage. A shipwreck is defined as the remains of a ship that has been wrecked—a destroyed ship at sea, whether it has sunk or is floating on the surface of the water. Overview A wreck is categorized as property belonging to no apparent owner that either sinks to the seabed or floats on the surface of the water, whether it be intentionally cast overboard or as the result of an accident. The term encompasses the hull of the vessel and its fixtures as well as any other form of object on board, such as cargo and stores, and personal effects of the crew and passengers. This also encompasses the narrower definition of salvage, that is, property that has been recovered from a wreckage, or the recovery of the ship itself. There are a number of factors that contribute to the formation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landforms Of Victoria Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
