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 multidisciplinary project carried out within the MAST framework. MATER combined physical and ecological modeling with intensive field activity carried out in the three sub–basins of the Mediterranean Sea that show a progressive eastward gradient of oligotrophy. The project objectives were:
to study and quantify the triggering and controlling transfer processes of mass (water, particles, natural and anthropogenic, stable and radioactive elements) and energy between the different compartments (land-sea, sea-atmosphere, upper-deep waters, water-sediment, living-nonliving, pelagos-benthos) in contrasting environments (from eutrophic to oligotrophic);
to appraise the time and space scales of the phenomena, in identified structures of the Mediterranean system; and
to investigate the ecosystem response to these transfers.

A multidisciplinary study of VERtical Transport and EXchange of material in the upper ocean performed in the California Current. It was organized to investigate the vertical exchange of materials between the photic zone and deeper waters in the Pacific Ocean. VERTEX was one of the first larger scale programs to focus on the couplings between new production and export. Components involved the use of particle traps and subsequent analyses of trapped particles for major elements, trace elements, radionuclides, fecal pellets and microbial populations to estimate vertical particulate fluxes.

A multi-national and multi-platform field program carried out in the Greenland and Norwegian Seas (north to Svalbard) from Sept. 1988 through May 1989. It was a collaboration between Canada, Denmark, France, Norway and the United States and consisted of four phases: the Polarbjorn Drift Phase, the Whaler’s Bay/SIZEX Phase, the Oceanography Camp Phase, and the Acoustic Camp Phase.
Industry:Earth science
A multiple net system used in biological oceanography to sequentially sample zooplankton at different depths or for collecting serial samples at the same depth.

A name given to strong, squally, southwest winds in the Straits of Gibraltar and off the east coast of Spain. It is associated with depressions and occurs mainly between September and March. They usually bring stormy weather and heavy rain.
Industry:Earth science
A name given to the region between the Kuroshio Extension and the Oyashio Front because it is a location where waters of subtropical, subpolar, and Sea of Japan origin meet and are transformed. This has also been referred to as the ”perturbed area” by Kawai.
Industry:Earth science
A name of a 1973 expedition, led by Henry Stommel, to perform trans-Pacific hydrographic sections at 28 and 43° S.
Industry:Earth science
A narrow channel in which sound waves can be effectively trapped. A region of minimum sound speed is created where the bottom of the thermocline meets the top of the deep isothermic layer. The velocity of sound slows as water temperatures decrease approaching the thermocline from above. The temperature is relatively constant below the thermocline, but increasing pressure causes the speed of sound to increase downwards. This causes obliquely traveling horizontal sound waves to vertically bend back and forth within the sound channel and travel great distances with relatively minor energy loss. This is also known as the SOFAR channel.
Industry:Earth science
A narrow constriction between South America and Antarctica between 56 and 63° S through which the Antarctic Circumpolar Current (ACC) must accelerate and squeeze in its trip around the globe. It is about 780 km wide at a depth of 500 m. Direct current and bottom pressure measurements in the Passage have led to estimates of ACC flow of around 110-130 Sv through it.
