The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [1] [2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3]
Deep-sea organisms generally inhabit bathypelagic (1,000–4,000 metres (3,281–13,123 ft) deep) and abyssopelagic (4,000–6,000 metres (13,123–19,685 ft) deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1,000 metres (656–3,281 ft) deep) zone as well. The ...
This is an eel trap that has been modified to better catch deep sea fauna. Life on the Edge 2005 Expedition. Deep-sea exploration is the investigation of physical, chemical, and biological conditions on the ocean waters and sea bed beyond the continental shelf, for scientific or commercial purposes.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Deep sea benthic fishes are more likely to associate with canyons or rock outcroppings among the plains, where invertebrate communities are established. Undersea mountains can intercept deep sea currents, and cause productive upwellings which support benthic fish. Undersea mountain ranges can separate underwater regions into different ecosystems.
Here we debunk 10 period myths, including why it's ok (and safe) to swim on your period, why your period does not stop in water, and more.
Surface currents are the water currents that are produced by the atmosphere's currents and its winds blowing over the surface of the water, producing wind waves, setting up through drag slow but stable circulations of water, as in the case of the ocean sustaining deep-sea ocean currents. Deep-sea currents, known together as the global conveyor ...
Deep-sea chimaera photographed by the NOAAS Okeanos Explorer.Visible on its snout are tiny pores which lead to electroreceptor cells.. Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to 150 cm (4.9 ft) in length.
