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 ...
A proposed remote sensing technique for monitoring the large scale distribution of surface salinity. It depends on the influence of salinity on microwave emissions, strongest at 1.4 GHz. Since temperature has a larger effect, high accuracy temperature measurements must also be made using another band at either 2.65 or 5.0 GHz. This yields a salinity accuracy of 0.05 parts per thousand, although this can be achieved only via long time (30 days) and space (100 km) averaging. A resolution of 10 km would degrade salinity measurement accuracy to 2 parts per thousand.

A protected areas network of federal, state and local partnerships to enhance informed management and scientific understanding of the U.S. estuarine and coastal habitats. It was created with the 1972 Coastal Zone Management Act. As of 272 1996, 22 estuarine reserves encompassing over 425,000 acres of estuarine waters, wetlands, and uplands have been designated, with another 6 reserves in development.

A ratio of buoyancy to inertial forces which measures the stability of a fluid layer. There are several different definitions of this for various situations,including the overall, gradient, and flux Richardson numbers.

A reasonably strict definition of this (also called a random process) is a family of random variables indexed by t, where t belongs to some index set T (which may denote time, space, or whatever else one wishes). A more intuitive definition might call this the set of all possible outcomes of an experiment (this set also being called the ensemble) inherently involving some degree of randomness along with the mechanism by which individual outcomes, or realizations, selected.

A recording thermometer which measures a continuous trace of temperature called a thermogram. The classical version of this featured a bi-metallic strip attached to a lever holding a pen. As the strip expanded and contracted in response to temperature changes, the pen moved across a piece of paper on a drum rotating via some clockwork mechanim. Such things are done using solid state devices sending binary data to other solid state devices in these modern times.

A reference level at which it is assumed the horizontal velocities are practically zero.

A reference level at which the horizontal velocities are thought to be practically zero.

A region centered to the west of Central America around 8–10°N and 88–90°W and about 200 to 400 km wide. Open ocean upwelling causes a domelike configuration of the local well–defined thermocline, bringing nutrients to the photic zone and sustaining increased biological productivity. This cyclonic gyre is located between the North Equatorial Countercurrent (NECC) to the south, the Costa Rica Coastal Current (CRCC) to the east and north, and the extension of the California Current and beginnings of the North Equatorial Current (NEC) to the north and northwest.

A regional sea contained within the Australasian Mediterranean Sea at the southwestern edge of the Pacific Ocean. It is centered at about 120° E and 8° N and connected to the Sulawesi Sea to the southeast via many passages through the Sulu Archipelago, the Bohol Sea to the east, and the South China Sea to the west and northwest chiefly via the Mindoro, Linapacan, North Balabac, and Balabac Straits. It borders the Philippine islands of Mindanao, Negros, and Panay to the east, Mindoro and the Calamin Group to the north, Palawan to the west, and the aforementioned Sulu Archipelago to the southeast. The Malaysian portion of the island of Borneo lies to the southwest.
