Cape Polar Sea
Cape Polar Sea () is a rock cape that forms the west extremity of Coulman Island in northwest Ross Sea. Named in 1998 by Advisory Committee on Antarctic Names (US-ACAN) after USCGC Polar Sea, an icebreaker in support of United States Antarctic Program (USAP) activities in the Ross, Amundsen and Bellingshausen Seas, and other Antarctic coastal areas during 11 seasons, 1980–1997. The cape lies in proximity to Cape Polar Star and Glacier Strait The Glacier Strait () is a natural waterway through the Canadian Arctic Archipelago within Qikiqtaaluk Region, Nunavut, Canada. It separates Ellesmere Island (to the north) from Coburg Island (to the south). To the north-east it opens into Baffin B ..., two features named earlier for American icebreakers.

Coulman Island
Coulman Island is an ice-covered island in the Ross Sea, located southeast of Cape Jones, Victoria Land, Antarctica. It is long, wide and in elevation. Emperor penguins inhabit this island. It was discovered in 1841 by Sir James Clark Ross who named it for his father-in-law, Thomas Coulman. A notable landmark of this island is Cape Anne, the south-easternmost point of the island, so named by Sir James Clark Ross for his wife. Cape Wadworth is the northernmost point of the island. The island is composed of several overlapping shield volcanoes that form part of the Hallett Volcanic Province of the McMurdo Volcanic Group. A wide and deep caldera called the Hawkes Heights can be found on the south end of the island. Important Bird Area (IBA) The island was founded in 1841, however, the island is currently recognized as an important bird area because it holds a huge super-colony of emperor penguins and is the largest colony of this species in the world. However, scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Sea
The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth. It derives its name from the British explorer James Clark Ross who visited this area in 1841. To the west of the sea lies Ross Island and Victoria Land, to the east Roosevelt Island and Edward VII Peninsula in Marie Byrd Land, while the southernmost part is covered by the Ross Ice Shelf, and is about from the South Pole. Its boundaries and area have been defined by the New Zealand National Institute of Water and Atmospheric Research as having an area of . The circulation of the Ross Sea is dominated by a wind-driven ocean gyre and the flow is strongly influenced by three submarine ridges that run from southwest to northeast. The circumpolar deep water current is a relatively warm, salty and nutrient-rich water mass that flows onto the continental shelf at certain locations. The Ross Sea is covered with ice ...

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] |
USCGC Polar Sea (WAGB-11)
USCGC ''Polar Sea'' (WAGB-11) is a United States Coast Guard heavy icebreaker. Commissioned on 23 February 1977, the ship was built by Lockheed Shipbuilding and Construction Company of Seattle along with her sister ship, ''Polar Star'' (WAGB-10). Her home port is Seattle, Washington. ''Polar Sea'' has been out of service due to failure of five of her six Alco main diesel engines. Machinery ''Polar Sea'' has a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the operation of the ship. Its three shafts are each turned by either one gas turbine or two diesel-electric power plants. Each shaft is connected to a 16-foot (4.9-m) diameter, four-bladed, controllable-pitch propeller. For all three shafts, the diesel-electric plants can produce a total of 18,000 shaft horsepower (13,425 kilowatts) and the gas turbine plants ...

United States Antarctic Program
The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean. United States Antarctic Program The United States established the U.S. Antarctic Research Program (USARP) in 1959—the name was later changed to the U.S. Antarctic Program—immediately following the success of the International Geophysical Year (IGY). Today, the National Science Foundation (NSF) has a Presidential Mandate to manage the United States Antarctic Program, through which it operates three year-round research stations and two research vessels, coordinates all U.S. science on the southernmost continent, and works with other federal agencies, the U.S. military, an ...

Headlands Of Victoria Land
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
