Hummock Island is off the western coast of West Falkland, in a bay that leads to the estuary of the Chartres River.Strange, Ian (1983) ''The Falkland Islands'' The highest point on the island is in the north-east and is . There are cliffs which often reach over high. Hummock Island is situated between Rabbit Island and Middle Island. Other islands in the Hummock Island group include Green Island and Gid's Island. In the middle of the Twentieth Century the island was used as an extension of the New Island sheep farm, and heavy grazing caused much of the Tussac grass to be eaten out. This has left areas of bare 'black ground'. However, the present owner has indicated that he will not restock the island but will allow the vegetation to recover. Gid's and Middle Islands are nature reserves. Im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, 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 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by Scientific Committee on Antarctic Research, SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He was the first person to scientifically measure the mass of the planet Earth. He created the ''British Nautical Almanac and Astronomical Ephemeris for the Meridian of the Royal Observatory at Greenwich'' using Johann Tobias Mayer's corrections for Euler's ''Lunar Theory'' tables. Biography Maskelyne was born in London, the third son of Edmund Maskelyne of Purton in Wiltshire, and his wife, Elizabeth Booth. Maskelyne's father died when he was 12, leaving the family in reduced circumstances. Maskelyne attended Westminster School and was still a pupil there when his mother died in 1748.
