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 WCRP program whose goal to to ascertain the role of the Arctic in global climate. The primary scientific objectives are:
* understanding the interactions between the Arctic Ocean circulation, ice cover and the hydrological cycle;
* initiating long-term climate research and monitoring programs for the Arctic; and
* providing a scientific basis for an accurate representation of Arctic processes in global climate models.
The components of ACSYS include:
* Arctic Ocean Circulation Program;
* Arctic Sea-Ice Program;
* Arctic Atmosphere Program;
* Hydrological Cycle in the Arctic Region;
* ACSYS Modeling Program; and
* Data Management and Information.
Industry:Earth science
The area comprising the Greenland Sea, the Iceland Sea, the Norwegian Sea and the Arctic Ocean. The first three are sometimes referred to as the Nordic Seas.
The area has restricted communication with the rest of the world ocean, with the passages being:
* to the Pacific via the Bering Strait;
* to the North Atlantic via the Greenland-Scotland Ridge; and
* through the Canadian Arctic Archipelago and the Davis Strait west of Greenland.

An ocean basin located to the west of Africa at about 15° S in the south-central Atlantic Ocean. It is demarcated to the north by the Guinea Ridge, south of which lies the Angola Abyssal Plain which is fed by the Congo Canyon, the largest in the eastern Atlantic. This has also been known as the Buchanan Deep.
Industry:Earth science
A method for locally refining grids in finite difference ocean models. The basic idea behind the method is to attain a given accuracy for a minimum amount of work. This is done by computing estimates of the truncation error, and creating refined grids (or removing existing ones) where and when it is necessary. The approach is also recursive so that fine grids can contain even finer grids.

A project of the APL at the University of Washington that took place in 1985.
Industry:Earth science
A small cyclonic gyre, centered near 10° S and 9° E, driven by the South Equatorial Undercurrent in the eastern Atlantic Ocean. It is called a dome due to the elevation or doming of the thermocline in the middle of the gyre. This is distinct from the larger gyre that incorporates the Angola Current.
Industry:Earth science
The repetition rate of a cyclic process measured in radians/sec. If the frequency in cycles/sec is f, then the angular frequency ω = 2πf.
Industry:Earth science
A type of water in the seas surrounding Antarctica with temperatures ranging from 0 to 0. 8° C, salinities from 34. 6 to 34. 7 ppt, and a depth range from a few hundred meters to about 1000-2000 m (3000 m (Tchernia)) It is formed from a mixture of overlying North Atlantic Deep Water (NADW) and underlying (at 1000-2000 m) Antarctic Bottom Water (AABW). It has a temperature maximum around 500-600 m and a salinity maximum between 700-1300 m. This was originally called Warm Deep Water (WDW) by Deacon, but renamed AACW by Sverdrup.
Industry:Earth science
The direction of rotation around a center of high pressure. This is clockwise in the northern hemisphere and counter-clockwise in the southern.
Industry:Earth science
One of three regions into which the North Atlantic Ocean is sometimes divided for the purposes of describing water mass formation processes in the region, with the other two being the (northward lying) arctic domain and the polar domain. Surface source water masses from the Atlantic domain (called Atlantic Water (AW), are carried into the arctic domain by the Norwegian Atlantic Current and, to a much smaller extent, by the North Icelandic Irminger Current.
