Founded in 1876, Texas A&M University is a U.S. public and comprehensive university offering a wide variety of academic programs far beyond its original label of agricultural and mechanical trainings. It is one of the few institutions holding triple federal designations as a land-, sea- and ...
The level of the sea with high frequency motions such as wind waves averaged out. See also mean sea level.

The long–term coexistence of plankton species that might be expected to compete. This is due to the degree to which chance encounters dictate the degree to which intra– or interspecific competition occurs. This, in turn, is due to plankton be unusually dependent on their physical environment for support, transport and food.
Industry:Earth science
The lower of two low waters on a day when the tide is neither predominantly diurnal nor predominantly semidiurnal but rather intermediate to either (a situation sometimes called a mixed tide).

The main source of sulfate particles and CCN over the oceans is the oxidation of DMS. As such the DMS may determine the concentrations and size spectra of cloud droplets and therefore the cloud albedo over large regions of the oceans. Marine stratiform clouds are of particular importance in this regard as they cover about one-quarter of the world’s oceans and therefore play a major role in the Earth’s radiative balance. This scenario is the basis for what is called the DMS-cloud-climate hypothesis.

The method developed by Knudsen and others in 1902 to determine the chlorinity and therefore salinity of a sea water sample.

The mission of which is to provide an observation–based description of the resources of California’s coastal ocean in support of science, coastal resource management and emergency response.
Industry:Earth science
The most voluminous of three major components of deep sea sediments, the other two being authigenic and biogenic. Detrital material is derived from the mechanical and chemical fragmentation of continental materials, most of which is in the form of alumino-silicate minerals. It is transported chiefly by rivers into coastal waters and by the wind onto the sea surface.
Industry:Earth science
The mutual adaptation of mass and momentum toward a steady geostrophic state in rotating fluids. The adjustment problem was first considered by Rossby (1938), who derived the geostrophically balanced steady end state for an ocean to which momentum is impulsively imparted. The end state always possesses less energy than the initial state, a fact due to the end state being achieved through decaying inertial oscillations which disperse energy away in pulses of Poincare waves.

The name given by Deacon (Deacon (1933), Deacon (1937)) to the hydrographic boundary between the Southern Ocean and subtropical waters to the north. This was replaced by the term Subtropical Front (STF) in the mid-1980s.
Industry:Earth science
The name given to a hypothetical northern hemisphere supercontinent consisting of North America, Europe, and Asia north of Himalayas prior to breaking up into its separate components. It was formed in the early Mesozoic by the rifting of Pangaea along the line of the North Atlantic Ocean and the Tethys Sea. The southern hemisphere analogue was called Gondwanaland and both comprised a hypothetical single supercontinent called Pangaea before their splitting up.
