Publications Ice Shelf
Publications Ice Shelf is an Antarctic ice shelf about 35 nautical miles (60 km) long on the south shore of Prydz Bay, between Mount Caroline Mikkelsen and Stornes Peninsula. Several glaciers, listed from southwest to northeast, nourish the ice shelf: Polar Times Glacier, Il Polo Glacier, Polarforschung Glacier, Polar Record Glacier and Polararboken Glacier. The feature was first mapped from air photos by the Lars Christensen Expedition, 1936–37. The name "Publication Glacier Tongues" was applied by John H. Roscoe in 1952 following his study of U.S. Navy Operation Highjump Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The opera ... (1946–47) air photos of the area, but the term ice shelf is more descriptive. So named by Roscoe because the several glaciers in the area comm ...

Prydz Bay
Prydz Bay is a deep embayment of Antarctica between the Lars Christensen Coast and Ingrid Christensen Coast. The Bay is at the downstream end of a giant glacial drainage system that originates in the East Antarctic interior. The Lambert Glacier flows from Lambert Graben into the Amery Ice Shelf on the south-west side of Prydz Bay. Other major glaciers drain into the southern end of the Amery Ice Shelf at 73° S where the marine part of the system starts at the modern grounding zone. The Amery Ice Shelf extends about 550 km north of the Lambert Glacier grounding zone and occupies a valley between 80 and 200 km wide. Depths to the bed beneath the Amery Ice Shelf are poorly known in detail but it is clearly over-deepened, reaching around -2500 m MSL close to the grounding zone. The Amery Ice Shelf occupies a very large U-shaped valley with exposed nunataks along the flanks reaching 1500 m in elevation and total relief as high as 3000 m. Seaward of the Amery Ice Shelf ...

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] |
Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ...

Mount Caroline Mikkelsen
Mount Caroline Mikkelsen is a small coastal mountain discovered on February 20, 1935. Its height is and it is between Hargreaves Glacier and Polar Times Glacier on Ingrid Christensen Coast. The mountain overlooks the southern extremity of Prydz Bay, north-northwest of Svarthausen Nunatak, and is the highest summit in the vicinity. It was discovered by Captain Klarius Mikkelsen in the ''Thorshavn'', a Norwegian whaling ship sent out by Lars Christensen. It is named for Captain Mikkelsen's wife Caroline Mikkelsen, who accompanied her husband on this voyage and became the first woman to set foot on Antarctica.
