Western Interior Seaway. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, and the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years. The ancient sea, which existed from the early Late Cretaceous (100 Ma ...
The location of the state of New Mexico. Paleontology in New Mexico refers to paleontological research occurring within or conducted by people from the U.S. state of New Mexico. The fossil record of New Mexico is exceptionally complete and spans almost the entire stratigraphic column. [1] More than 3,300 different kinds of fossil organisms have ...
Basins of the Rio Grande Rift Map of physiographic provinces of New Mexico. New Mexico is entirely landbound, with just 0.2% of the state covered with water, [1] and most of the state has an arid to semiarid climate. [2] Much of the state is mountainous, except for the easternmost Great Plains region. [3]
e. A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf. The continental margin, between the continental shelf and the abyssal ...
A stand of rare elkhorn coral off Mexico shows the effects of bleach from rising sea temperatures, which also have hammered reefs off the Florida Keys over the last few years.
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features. Topographic maps display elevation above ground ...
Sea surface temperature (or ocean surface temperature) is the temperature of ocean water close to the surface. The exact meaning of surface varies in the literature and in practice. It is usually between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. Sea surface temperatures greatly modify air masses in the Earth's ...
Sea surface temperature (SST), or ocean surface temperature, is the water temperature close to the ocean 's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. For comparison, the sea surface skin temperature relates to the ...
