McCarthy Point
McCarthy Point () is an ice-covered point that marks the northeastern extremity of Grant Island on the seaward edge of the Getz Ice Shelf, Antarctica. It was discovered and charted from the on February 4, 1962, and was named by the 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.

Grant Island
Grant Island is an ice-covered island, long and wide, lying east of the smaller Shepard Island off the coast of Marie Byrd Land, Antarctica. Like Shepard Island, Grant Island is surrounded by the Getz Ice Shelf on all but the north side. Grant Island was discovered and charted by personnel aboard on February 4, 1962. Grant Island was named by the United States 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 ... (US-ACAN) for Commander E. G. Grant, Commanding Officer of USS ''Glacier'' at the time of discovery.

Getz Ice Shelf
The Getz Ice Shelf is the largest Antarctic ice shelf along the SE Pacific-Antarctic coastline, over long and from wide, bordering the Hobbs and Bakutis Coasts of Marie Byrd Land between the McDonald Heights and Martin Peninsula. Several large islands are partially or wholly embedded in the ice shelf, pinning the calving front. Summer temperature and salinity measurements from 1994 to 2010 show the shelf is subject to more changeable oceanic forcing than other Antarctic shelves. Beneath cold surface waters, the thermocline was ~200 m shallower in 2007 than in 2000, indicative of shifting access of deep water to the continental shelf and ice shelf base. The calculated area-average basal melt rates was between 1.1 and 4.1 m of ice per year, making Getz the largest source of meltwater to the Southern Ocean. The ice shelf westward of Siple Island was discovered by the United States Antarctic Service (USAS) in December 1940. The portion eastward of Siple Island was first delineat ...

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] |
