This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included. Places where seawater and rainwater is pumped away are included.
Frisland was shown as a roughly rectangular island, with three triangular promontories on its western coast. In some mappings, it is identified as "Fixland". [4] (Matteo Prunes map of 1553, from Library of Congress, see upper right of map; see also, [5] page 88 for other clearer source; see also Catalan map of 1480 showing "Fixland"; [6] original source map copied in this article, page 64.
For example, snow cover and asphalt insulate the ground and homes can heat the ground (see also heat island). The line varies by latitude, it is deeper closer to the poles. The maximum frost depth observed in the contiguous United States ranges from 0 to 8 feet (2.4 m). [1] Below that depth, the temperature varies, but is always above 0 °C (32 ...
Cape Breton Island (French: île du Cap-Breton, formerly île Royale; Scottish Gaelic: Ceap Breatainn or Eilean Cheap Bhreatainn; Mi'kmaq: Unama'ki) [5] is a rugged and irregularly shaped island [6] on the Atlantic coast of North America and part of the province of Nova Scotia, Canada.
Map of Doggerland at its near maximum extent c. 10,000 years Before Present (~8,000 BCE) (top left) and its subsequent disintegration by 7,000 BP (~5,000 BCE). Doggerland was a large area of land in Northern Europe, now submerged beneath the southern North Sea.
Satellite image of sea ice forming near St. Matthew Island in the Bering Sea. Only the top layer of water needs to cool to the freezing point. [11] Convection of the surface layer involves the top 100–150 m (330–490 ft), down to the pycnocline of increased density.
Frost is a thin layer of ice on a solid surface, which forms from water vapor that deposits onto a freezing surface. Frost forms when the air contains more water vapor than it can normally hold at a specific temperature.
Oceanic islands between the Equator, 60°S, 20°W, and 115°E are the only Southern Hemisphere lands (besides East Timor) outside the five southern nuclear-weapon-free zones. Bouvet Island and the Kerguelen Islands are Antarctic islands on this map but outside the Antarctic NWFZ. Australian islands are parts of the South Pacific NWFZ.
