Undersea Canyon
A submarine canyon is a steep-sided valley cut into the seabed of the continental slope, sometimes extending well onto the continental shelf, having nearly vertical walls, and occasionally having canyon wall heights of up to 5 km, from canyon floor to canyon rim, as with the Great Bahama Canyon. Just as above-sea-level canyons serve as channels for the flow of water across land, submarine canyons serve as channels for the flow of turbidity currents across the seafloor. Turbidity currents are flows of dense, sediment laden waters that are supplied by rivers, or generated on the seabed by storms, submarine landslides, earthquakes, and other soil disturbances. Turbidity currents travel down slope at great speed (as much as 70 km/h), eroding the continental slope and finally depositing sediment onto the abyssal plain, where the particles settle out.Continental Margin Sedimentation: From Sediment Transport to Sequence Stratigraphy (Special Publication 37 of the IAS) Mar ...

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 ...

Oates Coast
Oates Coast () is that portion of the coast of Antarctica between Cape Hudson and Cape Williams. It forms the coast of Oates Land, part of the Australian claim to the Antarctic. The eastern portion of this coast was discovered in February 1911 by Lieutenant Harry Pennell, Royal Navy, commander of the expedition ship '' Terra Nova'' during the British Antarctic Expedition, 1910–13. He named the coast after Captain Lawrence E.G. Oates who, with Captain Robert F. Scott and three British Antarctic Expedition companions, perished on the return journey from the South Pole in 1912. Captain Oates' death was described by Robert Falcon Scott as "the act of a brave man and English gentleman". The western portion of the coast, the vicinity of the Mawson Peninsula Mawson Peninsula () is a high (), narrow, ice-covered peninsula on the George V Coast, on the west side of the Slava Ice Shelf, Antarctica, terminating in Cape Hudson. It extends for over in a northwesterly direction. The pe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
