83National Oceanographic Data Center — The National Oceanographic Data Center (NODC) is one of the national environmental data centers operated by the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce. The main NODC facility is located in Silver …
84Oceanic crust — Age of oceanic crust. The red is most recent, and blue is the oldest. Oceanic crust is the part of Earth s lithosphere that surfaces in the ocean basins. Oceanic crust is primarily composed of mafic rocks, or sima, which is rich in iron and… …
85Volcanic arc — Mariana Islands, an oceanic island arc A volcanic arc is a chain of volcanoes positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in a volcanic island arc. Generally they result from the subduction of an… …

87Tide gauge — A tide gauge. A tide gauge is a device for measuring sea level and detecting tsunamis. Sensors continuously record the height of the water level with respect to a height reference surface close to the geoid. Water enters the device by the bottom… …
88Cross sea — In surface navigation, a cross sea is a sea state with two wave systems traveling at oblique angles.[1] This may occur when water waves from one weather system continue despite a shift in wind. Waves generated by the new wind run at an angle to… …
89Oceanic basin — Diagrammatic cross section of an ocean basin, showing the various geographic features Hydrologically, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically ocean basins are large geologic basins that are below… …
90Dispersion (water waves) — This article is about dispersion of waves on a water surface. For other forms of dispersion, see Dispersion (disambiguation). In fluid dynamics, dispersion of water waves generally refers to frequency dispersion, which means that waves of… …
