The map of North America with the Western Interior Seaway during the Campanian. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, the Western Interior Sea and sometimes nicknamed "Hell's Aquarium") was a large inland sea that split the continent of North America into two landmasses for 34 million years.
During the early Paleozoic, southern and western New Mexico were submerged by a warm shallow sea that would come to be home to creatures including brachiopods, bryozoans, cartilaginous fishes, corals, graptolites, nautiloids, placoderms, and trilobites. During the Ordovician the state was home to algal reefs up to 300 feet high.
Habitats, physical features, or prey attract many threatened or endangered species — such as black abalone, blue whales, leatherback sea turtles, and snowy plovers — to the sanctuary's waters. [3] [7] Over 400 species of fish, four species of sea turtle, six species of pinniped, and 33 species of cetacean are found in the sanctuary's waters ...
Mid-ocean ridge cross-section (cut-away view) A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate ...
Sea ice is a composite material made up of pure ice, liquid brine, air, and salt. The volumetric fractions of these components—ice, brine, and air—determine the key physical properties of sea ice, including thermal conductivity, heat capacity, latent heat, density, elastic modulus, and mechanical strength.

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 ...
Cathy Cook, Albuquerque Journal, N.M. February 26, 2024 at 10:01 AM. Feb. 26—New Mexico Congresswoman Melanie Stansbury is calling on the Department of Homeland Security secretary to explain ...
In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from May 16, 2013, through September 12, 2013, when the sea ice reached its minimum area of coverage for 2013. Measurement of sea ice is important for safety of navigation and for monitoring the environment, particularly the climate.
