Deep Sea
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 metres (656 feet) or the point of transition from continental shelves to continental slopes. Conditions within the deep sea are a combination of low temperatures, darkness and high pressure The deep sea is considered the least explored Earth biome, with the extreme conditions making the environment difficult to access and explore. Organisms living within the deep sea have a variety of adaptations to survive in these conditions. Organisms can survive in the deep sea through a number of feeding methods including scavenging, predation and filtration, with a number of organisms surviving by feeding on marine snow. Marine snow is organic material that has fallen from upper waters into the deep sea. In 1960, the bathyscaphe ''Trieste'' descended to the bottom of the Mariana Trench near Guam, at , the deepest known spot in any ocean. If Mount Everest () were submerged there, it ...

Deepsea ASA
Odfjell Drilling Ltd. is an oil drilling, well service, and engineering company. Current operations The company has 3 divisions: * Mobile Offshore Drilling - Owns 6 drillships and operates in Norway, United Kingdom, Angola, Vietnam, and Brazil. * Drilling & Technology - provides platform drilling, project management and engineering services from offices in Bergen, Stavanger, and Aberdeen. * Well Services - provides casing and tubing running services (TRS), drill tool rental, and well intervention services to the onshore and offshore oil and gas industry. History The company was established in 1973 as an affiliate of Odfjell. In 1974, the first rigs were delivered from Aker ASA, and started service for ELF and Saga Petroleum. The first production drilling contract was awarded by Statoil on the Statfjord oil field in 1979. In 1984, the company expanded to the United Kingdom with a semi-submersible rig for Hamilton Brothers Oil & Gas. In 1989 the company opened an office in Singap ...

Deep Sea 3D
''Deep Sea 3D'' is a 3D IMAX documentary film about sea life. The documentary is directed by Howard Hall who has also directed other undersea films such as ''Into the Deep'' and ''Island of the Sharks''. The film is narrated by Johnny Depp and Kate Winslet. It also features music by Danny Elfman. The film is 40 minutes long. The film shows various sea animals, such as jellyfish, octopuses, and turtles as well as coral reef A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Co ... life.

Deep-Sea Trench
Oceanic trenches are prominent long, narrow topographic depressions of the ocean floor. They are typically wide and below the level of the surrounding oceanic floor, but can be thousands of kilometers in length. There are about of oceanic trenches worldwide, mostly around the Pacific Ocean, but also in the eastern Indian Ocean and a few other locations. The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of below sea level. Oceanic trenches are a feature of the Earth's distinctive plate tectonics. They mark the locations of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year. Oceanic lithosphere moves into trenches at a global rate of about 3 km2/yr. A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to and about from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep-sea Exploration
Deep-sea exploration is the investigation of physical, chemical, and biological conditions on the sea bed, for scientific or commercial purposes. Deep-sea exploration is considered a relatively recent human activity compared to the other areas of geophysical research, as the depths of the sea have been investigated only during comparatively recent years. The ocean depths still remain a largely unexplored part of the planet, and form a relatively undiscovered domain. In general, modern scientific deep-sea exploration can be said to have begun when French scientist Pierre Simon de Laplace investigated the average depth of the Atlantic ocean by observing tidal motions registered on Brazilian and African coasts. He calculated the depth to be , a value later proven quite accurate by echo-sounding measurement techniques.Deep Sea Exploration." World of Earth Science. Ed. K. Lee Lerner and Brenda Wilmoth Lerner.

Deepsea Mining
Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of or greater. As of 2021, the majority of marine mining efforts are limited to shallow coastal waters only, where sand, tin and diamonds are more readily accessible. There are three types of deep sea mining that have generated great interest: polymetallic nodule mining, polymetallic sulphide mining, and the mining of cobalt-rich ferromanganese crusts. The majority of proposed deep sea mining sites are near of polymetallic nodules or active and extinct hydrothermal vents at below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be processed. Marine minerals include sea-dredged and seabed minerals. Sea-dred ...

Deep-sea Submersible
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs (Deep Submergence Rescue Vehicle), which can be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions (primarily installing wiretaps on undersea communications cables), or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole. The real-life feasibility of any DSRV-based rescue attempt is hotly debated, because the few available docking chambers of a stricken submarine may be flooded, trapping the sailors still alive in other dry compartments. The only attempt to rescue a stricken submarine with these so far (the Russian submarine ''Kursk'') ended in failure as the entire crew who survived the explosion had either suffocated or ...
