Abbot Ice Shelf
The Abbot Ice Shelf is an ice shelf long and wide, bordering Eights Coast from Cape Waite to Pfrogner Point in Antarctica. Thurston Island lies along the northern edge of the western half of this ice shelf; other sizable islands ( Sherman, Carpenter, Dustin, Johnson, McNamara, Farwell and Dendtler) lie partly or wholly within this shelf. The ice shelf was sighted by members of the U.S. Antarctic Service in flights from the ship ''Bear'', in February 1940, and its western portion was delineated from air photos taken by U.S. Navy (USN) Operation HIGHJUMP, 1946–47. The full extent was mapped by the U.S. Geological Survey from USN air photos of 1966. It was named by the Advisory Committee on Antarctic Names for Rear Admiral James Lloyd Abbot, Jr., Commanding Officer, U.S. Naval Support Force, Antarctica, February 1967 to June 1969.

Sherman Island (Antarctica)
Sherman Island is an ice-covered island of Antarctica about long and wide, lying south of Thurston Island in the middle of Peacock Sound. The feature rises above the Abbot Ice Shelf which occupies the sound. It was delineated from aerial photographs taken by US Navy Operation HIGHJUMP in December 1946, and named by the Advisory Committee on Antarctic Names for Admiral Forrest Sherman, USN, Chief of Naval Operations, when preparations were being made for U.S. Naval support during the forthcoming International Geophysical Year operations.

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farwell Island
Farwell Island is an ice-covered island, about long and wide, lying between McNamara Island and Dendtler Island in the eastern part of the Abbot Ice Shelf in Antarctica. The feature was positioned by parties from the USS ''Glacier'' and USS ''Staten Island'' in February 1961, and was mapped by the United States Geological Survey from U.S. Navy air photos of 1966. It was named by the Advisory Committee on Antarctic Names for Captain Arthur F. Farwell, Chief of Staff to the Commander, U.S. Naval Support Force, Antarctica, during Operation Deep Freeze Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on.
