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 marginal sea of the North Atlantic Ocean which consists of the waters between the continental shelves of Norway and Spitsbergen to the east and the Mohn Ridge and Jan Mayen Ridge to the west. It adjoins the Barents Sea to the northeast, the Greenland Sea to the northwest, the Iceland Sea to the west, and the North Sea to the southeast. It covers an area of 1,383,000 km2, has a volume of 2,408,000 km3, and a mean depth of 1742 m. The term Norwegian Sea has also been used to collectively refer to the sea described here along with the Greenland Sea and the Iceland Sea.

A marine geologist (1920-1986) at Scripps who in 1958 suggested a continuous process of mid-ocean ridge development.

A MAST program for the observation and modeling of the large–scale movement of the Mediterranean Water (MW) and Labrador Sea Water (LSW) in the eastern North Atlantic Ocean. The principal objectives are: determining the mean circulation of the MW and LSW in the intergyre region of the eastern North Atlantic, and discovering if there is a Stokes drift or eddy mixing of the MW and LSW. A large part of EUROFLOAT will be a lagrangian circulation experiment wherein subsurface neutrally buoyant floats will be used to observe the movement of deep water masses over a period of 3 years. The ARCANE project is a companion study to this.

A MAST-3/MATER program and companion to the ALGERS project. ELISA was an interdisciplinary project to investigate the Western Mediterranean Sea, looking at the role of the Algerian Basin through the detailed study of the Algerian Current. The field work took place between July 1997 and July 1998 and involved 44 scientists from 8 countries. The objectives were to study:
the general circulation of the water masses, i.e. MAW, LIW and WMDW;
the Algerian eddies origin, structure and trajectories;
the biological activity associated with the mesoscale dynamic phenomena; and
the role of the mesoscale dynamics on the biological functioning of the Algerian Basin.
Industry:Earth science
A mean Lagrangian current that can be generated by surface gravity waves. This is caused when water particle orbits are not closed in surface gravity waves. A steady drift results even if no mean currents are present.
Industry:Earth science
A measure of the attenuation of solar radiation by the atmosphere that allows the convenience of considering as a single unit the losses due to scattering and absorption processes. The greater the thickness, the greater the attenuation of incoming solar radiation. This is also referred to as the optical depth.

A measurement program taking place from August 1987 to June 1988 that focused on the interactions of atmospheric forcing, mixed layer dynamics and inertial motions, with the aim of improving understanding of upper ocean response to atmospheric forcing. The experiment took place in the autumn in the northeast Pacific, and was concentrated just south of the normal storm track since historical data suggested that it would be a place of rapid mixed layer deepening and strong, storm–forced inertial currents. It was also an area where a low level of mesoscale eddy energy minimized advection and the interaction of eddies and inertial currents.
Industry:Earth science
A measuring system that uses high frequency radio pulses to probe the ocean surface to deduce near–surface currents. The shore–based system consists of two units which are deployed several kilometers apart. Each unit makes independent measurements of current speed along radials emanating from its phased–array antennae system. The data are then combined via UHF or telephone communication to produce accurate vector currents, store them to disk, and display them in near real time. Measurements can be made simultaneously at up to 700 grid points at either 1 km or 250 m resolution. The OSCR samples for about 10 minutes and then processes radar returns for about 10 minutes to create a quasi-synoptic surface current map every 20 minutes.
Industry:Earth science
A mechanism that acts in diatom–dominated communities to enhance the loss of silicate from the euphotic zone to deep water compared to nitrogen, which is more readily recycled in the grazing loop, thus leading the system to silicate limitation. The silicate pumping to deep water results in low silicate, high nitrate conditions in the mixed layer. In such situations silicate dynamics may control and dominate new production processes and consequently control the rate at which newly upwelled CO2 in the surface regions is reduced by the phytoplankton.
Industry:Earth science
A meteorologist (1910–1997) who was one of the best long–range forecasters.
