Smith Peninsula
The Smith Peninsula () is an ice-covered, "dog-legged" peninsula long and wide, extending in an easterly direction between Keller Inlet and Nantucket Inlet from the east coast of Palmer Land, Antarctica. Location The Smith Peninsula is in southeast Palmer Land, on the Lassiter Coast of the Weddell Sea. It lies between Nantucket Inlet to the southwest and Keller Inlet to the northeast. Johnston Glacier flows past the west of the peninsula to Nantucket Inlet. Barcus Glacier flows past the north of the peninsula to Keller Inlet. The Hutton Mountains are to the north of the peninsula. Cape Fiske is the easternmost point. Discovery and naming The Smith Peninsula was photographed from the air in December 1940 by members of the United States Antarctic Service Expedition (USAS), and in 1947 by members of the Ronne Antarctic Research Expedition (RARE) under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner–Ronne Ice Shelf, Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emperor Penguin
The emperor penguin (''Aptenodytes forsteri'') is the tallest and heaviest of all living penguin species and is Endemism in birds, endemic to Antarctica. The male and female are similar in plumage and size, reaching in length and weighing from . Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all species of penguin, the emperor is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of . It has several adaptations to facilitate this, including an unusually structured Hemoglobin, haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential ...

Important Bird Areas Of Antarctica
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been witho ...

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] |
United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

Nantucket Island
Nantucket () is an island in the state of Massachusetts in the United States, about south of the Cape Cod peninsula. Together with the small islands of Tuckernuck and Muskeget, it constitutes the Town and County of Nantucket, a combined county/town government. Nantucket is the southeasternmost town in both Massachusetts and the New England region. The name "Nantucket" is adapted from similar Algonquian names for the island. Nantucket is a tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to around 80,000 during the summer months. The average sale price for a single-family home was $2.3 million in the first quarter of 2018. The National Park Service cites Nantucket, designated a National Historic Landmark District in 1966, as being the "finest surviving architectural and environmental example of a late 18th- and early 19th-century New England seaport town." History Etymology Nantucket probably takes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
