The bottom of the ocean is a very important place for marine life. We call this mode of life 'benthic. Some species even live under the surface of the bottom of the ocean called infauna. The bottom of the ocean is a major area of decomposition where organic material is recycled cells are broken down and nutrients are released by bacteria and fungi. Ocean bottom sediment map. The actual physical bottom of the ocean or substrate is generally some type of rock or sediment and can be categorized as terrogenous, biogenous or hydrogenous.
The seabed also known as the seafloor , sea floor , or ocean floor is the bottom of the ocean. Most of the oceans have a common structure, created by common physical phenomena, mainly from tectonic movement, and sediment from various sources. The structure of the oceans, starting with the continents, begins usually with a continental shelf , continues to the continental slope — which is a steep descent into the ocean, until reaching the abyssal plain — a topographic plain , the beginning of the seabed, and its main area. The border between the continental slope and the abyssal plain usually has a more gradual descent, and is called the continental rise , which is caused by sediment cascading down the continental slope. The mid-ocean ridge , as its name implies, is a mountainous rise through the middle of all the oceans, between the continents.
The shipwreck has been excavated before, but this particular find uncovered 60 gold artifacts from the area where eleven Spanish ships sank on July 31, Previous excavations have turned up other important pieces, giving the stretch of Florida coastline the name Treasure Coast. Florida-based company Queens Jewels owns the rights to the exploration of the wreck and announced the find on Monday.
May 22, Pompeii worms, clams, and snails with iron scales armoring their feet are not exactly the cuddly icons that open checkbooks during environmental fundraisers. For decades, the prospect that companies would seek fortunes on the seafloor has seemed remote, says Porter Hoagland , a marine-policy specialist at the Woods Hole Oceanographic Institution in Woods Hole , Mass. Deep-sea exploration and extraction technologies have improved.
