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 circulation pattern found in models of enclosed basins where the boundary condition is surface water forcing using the natural, mass-flux boundary condition rather than a rigid lid with virtual salt forcing. This results in a barotropic circulation pattern that is similar to the wind-driven subtropical and subpolar gyres but rotating in the reverse direction.

A class of chemicals being used to replace CFCs since they deplete stratospheric ozone to a much lesser extent than CFCs. These have ODPs ranging from 0.01 to 0.1. The production of these chemicals is being gradually phased out, with those with the highest ODPs going first. These will be replaced by HFCs or some other types of chemicals.

A class of chemicals being used to replace CFCs. They do not contain chlorine or bromine and therefore do not deplete ozone in the stratosphere. These all have an ODP value of zero but can have high GWP values.

A clearinghouse created at WHOI to collect and broadcast information about lost and found oceanographic research equipment. It is implemented as a moderated mailing list to which interested parties can subscribe.

A clockwise/counterclockwise circulation in the northern/southern hemisphere that is forced by the wind and features western intensification in the form of a western boundary current. In the northern hemisphere the gyres span the width of the oceans and extend from about 10 to 40 °N with the boundary currents in the Atlantic and Pacific called, respectively, the Gulf Stream and the Kuroshio. There are analogous features in the southern hemisphere. The polar boundaries between these and the subpolar gyres coincide with the latitude at which the curl of the wind stress vanishes, the latter being largely the mechanism of causation.

A coefficient measuring the rate of extinction, or diminution, with distance of transmitted light in sea water. It is the attenuation coefficient for visible radiation.

A coherent structure found in the upper ocean that has been observed in both stable and unstable conditions. These are found in the upper few meters, are aligned with the wind, and marked by horizontal temperature changes of 0.1 K over 0.1 m. They indicate the upward transport of cool/warm fluid during stable/unstable conditions, and are driven by an instability triggered by the wind thought to be similar to the Kelvin–Helmholtzinstability. These are as yet not well understood.

A cold current that flows from the Okhotsk Sea into the Japan Sea. Part of this current continues south along the western coast and eventually becomes the North Korea Current.

A collaboration between the E. Firing ADCP Laboratoary at the University of Hawaii and the NODC. This center, formerly known as the Shipboard ADCP Center (SAC), is responsible for the acquisition, review, documentation, archiving, and distribution of shipboard ADCP data sets. It primarily handles U.S. national cruises, but also supports such multi–national programs as TOGA COARE, WEPOCS, and US–PRC cruises. The JASADCP is also a Data Assembly Center for WOCE in collaboration with the JODC.

A collection of NOAA programs attempting to understand the influence of environment on the abundance of various commercially valuable fish and shellfish stocks in Alaskan waters and their role in the ecosystem.
