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 vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haswell Island
Haswell Island is the largest of the Haswell Islands, lying off the coast of Antarctica, about north of Mabus Point in Queen Mary Land. It was discovered by the Western Base Party of the Australasian Antarctic Expedition, 1911–14, under Mawson, and named by him for Professor William A. Haswell, a zoologist at Sydney University and a member of the expedition's Advisory Committee. Birds The island is a unique site for almost all bird species breeding in East Antarctica, including Antarctic petrels, Antarctic fulmars, Cape petrels, snow petrels, Wilson's storm petrels, south polar skuas and Adélie penguins. To the south-east of the island, there is a large colony of emperor penguins breeding on fast ice. The island and the adjacent emperor penguin rookery site are protected under the Antarctic Treaty System as Antarctic Specially Protected Area (ASPA) No.127. The same 500 ha site, comprising the whole island as well as the adjoining sea ice where the emperor penguins br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haswell Islands
The Haswell Islands are a group of rocky coastal islands lying off Mabus Point, Antarctica, and extending about seaward. They were charted by the Australasian Antarctic Expedition under Douglas Mawson (1911–14), who applied the name "Rookery Islands" because of a large emperor penguin rookery on Haswell Island, the largest and seaward island in the group. In 1955 the Antarctic Names Committee of Australia proposed that the name Haswell be extended to the entire group.
