51Ocean thermal energy conversion — Temperature differences between the surface and 1000m depth in the oceans Ocean Thermal Energy Conversion (OTEC) uses the difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work,… …
52Downwelling — is the process of accumulation and sinking of higher density material beneath lower density material, such as cold or saline water beneath warmer or fresher water or cold air beneath warm air. It is the sinking limb of a convection cell.… …
53DSV Alvin — ALVIN redirects here. For other uses, see Alvin. Alvin in 1978, a year after first exploring hydrothermal vents. Alvin (DSV 2) is a manned deep ocean research submersible owned by the United States Navy and operated by the Woods Hole… …
54Seafloor spreading — Age of oceanic crust; youngest (red) is along spreading centers. Seafloor spreading is a process that occurs at mid ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor… …
55Transform fault — (the red lines) A transform fault or transform boundary, also known as conservative plate boundary since these faults neither create nor destroy lithosphere, is a type of fault whose relative motion is predominantly horizontal in either sinistral …
56Marginal sea — Marginal seas as defined by the IMO …
57Divergent boundary — In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent… …
58Convergent boundary — In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As …
59Seawater — in the Strait of Malacca Seawater is water from a sea or ocean. On average, seawater in the world s oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one litre by volume) of seawater has… …
