Glimpse Glacier
Koettlitz Glacier () is a large Antarctic glacier lying west of Mount Morning and Mount Discovery in the Royal Society Range, flowing from the vicinity of Mount Cocks northeastward between Brown Peninsula and the mainland into the ice shelf of McMurdo Sound. Naming and exploration Koettlitz Glacier was discovered by the British National Antarctic Expedition (1901–04) which named it for Dr. Reginald Koettlitz, physician and botanist of the expedition. Glaciology The Koettlitz Glacier appears to have been smaller during the Last Glacial Maximum (LGM) than it is today, while the Ross Ice Shelf was larger. There is evidence that during the LGM the mouth of the Pyramid Trough was blocked by grounded Ross Sea ice until at least 11,000 years ago. In the last 3,000 years the glacier has advanced, and today the mouth of ice-free Pyramid Trough is blocked by the Koettlitz Glacier. Under this hypothesis, the glacier may have been thicker at the coast due to buttressing, but may have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Dependency
The Ross Dependency is a region of Antarctica defined by a circular sector, sector originating at the South Pole, passing along longitudes 160th meridian east, 160° east to 150th meridian west, 150° west, and terminating at latitude 60th parallel south, 60° south. It is claimed by New Zealand, a claim mutually accepted only by Australia, the United Kingdom, UK, France and Norway, which are countries that also have territorial claims in Antarctica. Under the 1961 Antarctic Treaty System, Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". The Dependency takes its name from James Clark Ross, Sir James Clark Ross, who discovered the Ross Sea and includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
