WThe Amerasia Basin, or Amerasian Basin, is one of the two major basins from which the Arctic Ocean can be subdivided. The triangular-shaped Amerasia Basin broadly extends from the Canadian Arctic Islands to the East Siberian Sea, and from Alaska to the Lomonosov Ridge. The basin can be further subdivided based on bathymetric features; these include the Canada Basin, the Makarov Basin, the Podvodnikov Basin, the Alpha-Mendeleev Ridge, and the Chukchi Plateau.
WThe Amundsen Basin, with depths up to 4.4 km (2.7 mi), is the deepest abyssal plain in the Arctic Ocean. The Amundsen Basin is embraced by the Lomonosov Ridge and the Gakkel Ridge. It is named after the polar researcher Roald Amundsen. Together with the Nansen Basin, the Amundsen Basin is often summarized as Eurasian Basin.
WThe Arctic Basin is an oceanic basin in the Arctic Ocean, consisting of two main parts separated by the Lomonosov Ridge, a mid-ocean ridge running between north Greenland and the New Siberian Islands. The basin is bordered by the continental shelves of Eurasia and North America. The Eurasian Basin consists of the Nansen Basin and the Amundsen Basin The Amerasia Basin consists of the Canada Basin and the Makarov Basin
WThe Canada Basin is a deep oceanic basin within the Arctic Ocean. It is part of the Amerasian Basin.
WThe Canadian Arctic Rift System is a major North American geological structure extending from the Labrador Sea in the southeast through Davis Strait, Baffin Bay and the Arctic Archipelago in the northwest. It consists of a series of interconnected rifts that formed during the Paleozoic, Mesozoic and Cenozoic eras. Extensional stresses along the entire length of the rift system have resulted in a variety of tectonic features, including grabens, half-grabens, basins and faults.
WThe Eurasia Basin, or Eurasian Basin, is one of the two major basins into which the Arctic Basin of the Arctic Ocean is split by the Lomonosov Ridge. The Eurasia Basin may be seen as an extension of the North Atlantic Basin through Fram Strait. It is further split by the mid-ocean Gakkel Ridge into the Nansen Basin and the Amundsen Basin. The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole is located there.
WFoxe Basin is a shallow oceanic basin north of Hudson Bay, in Nunavut, Canada, located between Baffin Island and the Melville Peninsula. For most of the year, it is blocked by sea ice and drift ice made up of multiple ice floes.
WThe Greenland Abyssal Plain at 75°N 3°W is a bathymetric depression in the Greenland Sea. It is delimited by Mohns Ridge and Jan Mayen pressure zone in the South and separated by a smaller ridge to the Boreas Abyssal Plain in the North.
WThe Molloy Deep is a bathymetric feature in the Fram Strait, within the Greenland Sea east of Greenland and about 160 km west of Svalbard. It is the location of the deepest point in the Arctic Ocean.
WThe Nansen Basin is an abyssal plain with water-depths of around 3 km in the Arctic Ocean and part of the Eurasian Basin. It is named after Fridtjof Nansen. The Nansen Basin is bounded by the Gakkel Ridge on the one side and by the Barents Sea continental shelf on the other.
