Godel Iceport
Godel Iceport is an iceport about wide, which marks a more-or-less permanent indentation in the seaward front of the extensive ice shelf fringing the coast of Queen Maud Land. Discovery and naming Godel Iceport was named by United States Navy Operation Deep Freeze I personnel on the USS ''Glacier'' (AGB-4), who made a running survey of this coast in March 1956, for William H. Godel, deputy director of the Office of Special Operations, Department of the Navy, who assisted in formulating expedition plans and policy. The term "iceport" was suggested by the Advisory Committee on Antarctic Names in 1956 to denote an ice shelf indentation, subject to configuration changes, which may offer anchorage or possible access to the upper surface of an ice shelf via ice ramps along one or more sides of the feature.

Iceport
An iceport is a more-or-less permanent indentation in the front of an ice shelf, that can serve as a natural ice harbour. Though useful, they are not always reliable, as calving of surrounding ice shelves can render an iceport temporarily unstable and unusable. Historical and present use of iceports Iceports have played a critical role in Antarctic exploration. For example, the Bay of Whales (discovered and named by Ernest Shackleton in the ''Nimrod'' in 1908) served as the base for several important Antarctic expeditions, including: * 1910-1912: Amundsen's South Pole expedition, led by Roald Amundsen * 1928-1930: Richard Evelyn Byrd - First expedition * 1933-1935: Richard Evelyn Byrd - Second expedition * 1939-1941: United States Antarctic Service Expedition, led by Richard Evelyn Byrd Norsel Iceport was used by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) to moor and unload the expedition ship in 1949. The NBSAE established Maudheim Station about 1 mile south of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Whales
The Bay of Whales was a natural ice harbour, or iceport, indenting the front of the Ross Ice Shelf just north of Roosevelt Island, Antarctica. It is the southernmost point of open ocean not only of the Ross Sea, but worldwide. The Ross Sea extends much further south – as far as the Gould Coast, some from the South Pole – but most of that area is covered by the Ross Ice Shelf rather than open sea. Discovery and naming Ernest Shackleton named the feature on January 24, 1908, during the Nimrod Expedition, because of the large number of whales seen near this location. History During his quest for the South Pole, Norwegian explorer Roald Amundsen established a temporary base, which he named Framheim, at the Bay of Whales. The base was used between January 1911February 1912, and was named after Amundsen's ship ''Fram''. The Bay of Whales has also served as a logistical support base for several other important Antarctic expeditions, including: * 1928–1930: Richard Evelyn ...

Norsel Iceport
Norsel Iceport (), also known as Norselbukta or Bukhta Nursel, is a small iceport in the front of the Quar Ice Shelf, along the coast of Queen Maud Land. Discovery and naming This feature was named by the Norwegian–British–Swedish Antarctic Expedition (NBSAE), 1949–52, which used it to moor and unload the expedition ship . The low ice front permitted easy access onto Quar Ice Shelf, where the NBSAE established Maudheim Station about 1 nautical mile south of the iceport.

Erskine Iceport
Erskine Iceport (), also known as Erskine Bay or General Erskine Bay, is an iceport about wide and long, which marks a more-or-less permanent indentation extending southeast into the seaward front of the extensive ice shelf fringing Queen Maud Land. Discovery and naming United States Navy Operation Deep Freeze I personnel on the USS ''Glacier'' made a running survey of this coast in March 1956. They applied the name "General Erskine Bay" for General Graves B. Erskine, United States Marine Corps, director of the U.S. Navy Office of Special Operations, who assisted in formulating expedition plans and policy. The term "iceport" was suggested by the Advisory Committee on Antarctic Names in 1956 to denote an ice shelf indentation, subject to configuration changes, which may offer anchorage or possible access to the upper surface of an ice shelf via ice ramps along one or more sides of the feature.

Atka Iceport
Atka Iceport, also known as Atka Bay, is an iceport about long and wide, marking a more-or-less permanent indentation in the front of the Ekstrom Ice Shelf on the coast of Queen Maud Land. Discovery and naming Atka Iceport was mapped in detail by Norwegian cartographers from surveys and air photographs taken by the Norwegian-British-Swedish Antarctic Expedition (1949-1952), led by John Schjelderup Giæver. It was named by personnel of the USS ''Atka'', under U.S. Navy Commander Glen Jacobsen, which moored here in February 1955 while investigating possible base sites for International Geophysical Year operations. Station Atka Bay is the site of Germany's Neumayer-Station III. Important Bird Area A 425 ha tract of sea ice in the bay has been identified as an Important Bird Area by BirdLife International because it supports a breeding colony of about 12,000 emperor penguins.

Ice Pier
An ice pier or ice wharf is a man-made structure used to assist the unloading of ships in Antarctica. It is constructed by pumping seawater into a contained area and allowing the water to freeze. By repeating this procedure several times, additional layers are built up. The final structure is many metres in thickness, and strong enough to support container trucks. Operation Deep Freeze personnel constructed the first floating ice pier at Antarctica’s southernmost sea port at McMurdo Station in 1973."Unique ice pier provides harbor for ships," Antarctic Sun. January 8, 2006; McMurdo Station, Antarctica. Ice piers have been in use each season since, at McMurdo's natural [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anchor
An anchor is a device, normally made of metal , used to secure a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin ''ancora'', which itself comes from the Greek ἄγκυρα (ankȳra). Anchors can either be temporary or permanent. Permanent anchors are used in the creation of a mooring, and are rarely moved; a specialist service is normally needed to move or maintain them. Vessels carry one or more temporary anchors, which may be of different designs and weights. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. A drogue is a drag device used to slow or help steer a vessel running before a storm in a following or overtaking sea, or when crossing a bar in a breaking sea.. Overview Anchors achieve holding power either by "hooking" into the seabed, or mass, or a combination of the two. Permanent moorings use large masses (common ...

United States Department Of The Navy
The United States Department of the Navy (DoN) is one of the three military departments within the Department of Defense of the United States of America. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN);Bernard C. Steiner and James McHenry, The life and correspondence of James McHenry' (Cleveland: Burrows Brothers Co., 1907). since 1834, it has exercised jurisdiction over the U.S. Marine Corps (USMC) and, during wartime, the U.S. Coast Guard (USCG), though each remains an independent service branch. It is led by the Secretary of the Navy (SECNAV), a statutory civilian officer. The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military service ...

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Running Survey
A running survey is a rough survey made by a vessel while coasting. Bearings to landmarks are taken at intervals as the vessel sails offshore, and are used to fix features on the coast and further inland. Intervening coastal detail is sketched in. The method was used by James Cook, and subsequently by navigators who sailed under—or were influenced by—him, including George Vancouver, William Bligh and Matthew Flinders Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a British navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to u .... References Navigation Surveying James Cook {{Hydrography-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
