91Marine geology — Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. Marine geology or geological oceanography involves geophysical, geochemical, sedimentological and paleontological… …
92Outer trench swell — The outer trench swell, outer trench high, or outer rise is a subtle ridge on the seafloor near an oceanic trench, where a descending plate begins to flex and fault in preparation for its descent into the mantle at a subduction zone. The… …
93Coastal geography — is the study of the dynamic interface between the ocean and the land, incorporating both the physical geography (i.e coastal geomorphology, geology and oceanography) and the human geography (sociology and history) of the coast. It involves an… …
94Deep ocean water — (DOW) is the name for cold, salty water found deep below the surface of Earth s oceans. Ocean water differs in temperature and salinity, with warm, relatively non salty water found at the surface, and very cold salty water found deeper below the… …

96Swell (ocean) — Ocean swell redirects here. For the thoroughbred racehorse, see Ocean Swell. Breaking swell waves at Hermosa Beach, California …
97Deep sea — zones For the IMAX film, see Deep Sea 3D. The deep sea, or deep layer[1], is the lowest layer in the ocean, existing below the thermocline and above the seabed, at a depth of 1000 fathoms …
98Pelagic sediments — Pelagic sediment or pelagite is a fine grained sediment that has accumulated by the settling of particles through the water column to the ocean floor beneath the open ocean far from land. These particles consist primarily of either the… …
99Eddy (fluid dynamics) — Downwind of obstacles, in this case, the Madeira and the Canary Islands off the west African coast, eddies create turbulent patterns called vortex streets …
100Oceanic plateau — An oceanic plateau (also submarine plateau) is a large, relatively flat submarine region that rises well above the level of the ambient seabed.[1] While many oceanic plateaus are composed of continental crust, and often form a step interrupting… …
