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 ...
Interannual variations in the atmospheric pressure at sea level, wind stress, sea surface temperature and sea-ice extent that propagate eastwards around the Southern Ocean. These anomalies propagate with the circumpolar flow with a period of 4-5 years and taking 8-10 years to circle the pole.

In meterology, a front which develops and persists around the Antarctic continent at about 60-65° S, and divides Antarctic Air from the maritime Polar Air to the north.

An international organization that promotes the interests of limnology, oceanography and related sciences,fosters the exchange of information across the range of aquatic science, and furthers investigations dealing with these subjects. ASLO originated with the Limnological Society of America (LSA), which was established in 1936 to furhter interest and research in limnological science. In 1948 LSA merged with the Oceanographic Society of the Pacific to become ASLO, and currently has over 3800 memebers from 50 countries.

A current flowing beneath the Agulhas Current. LADCP measurements indicate the core is centered around 1200 m, against the continental slope and directly below the surface core of the southwestward flowing Agulhas Current. Maximum velocities of 30 cm/s to the northeast are observed in the undercurrent, and its volume transport is 6 Sv, about a tenth that of the overlying Agulhas.

A global array of 3,000 free-drifting profiling floats that will measure the temperature and salinity of the upper 2000 m of the ocean. This will allow the continuous monitoring of the climate state of the ocean. Once the full network is in place in 2002 or thereabouts, Argo will provide 100,000 T/S profiles and reference velocity measurements per year from floats distributed over the oceans at about a 3 degree spacing. The floats will cycle to 2000 m depth every 10 days, with a planned 4-5 year lifetime for individual instruments. All data will be made publicly available in near real-time via the GTS, and in scientifically quality-controlled form within a few months.

A strong subsurface to intermediate depth front beneath the upper 100-150 m that originates at around 20°-25° E below the southern tip of Africa. It extends to between 65°-90° E where it merges with the Southern Subtropical Front in the Indian Ocean sector of the ACC. The chief identification criterion is usually the depth range of the 10° isotherm, about 300-800 m south of Africa at 16°-27° E. This range shrinks to about 400-650 m to the east in the Kerguelan-Amsterdam passage, indicating the gradual weakening of the AF. A thermostad on the warm side of the AF in the 150-300 m layer is another useful identification criterion. This thermostad cools and freshens to east, ranging from 17°-18° C/35. 5-35. 6 at 20° E to 12°-14° C/35. 2-35. 4 at 70° E.

A part of the Baltic Sea bordered by the Gulf of Bothnia to the north, the Gulf of Finland to the east, and the man part of the Baltic Sea to the south.
Industry:Earth science
A multi-function sampling device providing high resolution concurrent sampling of physical, chemical and biological parameters throughout the water column from a moving ship. ARIES is modular, being composed of a water sampling unit, a plankton sampling unit and an oceanographic sensor unit.
Industry:Earth science
An experiment to measure the magnitude of heat flux through the air-sea-ice interface and to describe the mechanisms that drive and control the fluxes of heat, salt and momentum. It took place aboard the RV Nathaniel B. Palmer in the Eastern Weddell Sea from June 27 to August 24, 1994.
