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 ...
An oceanographic experiment which took place in the Alboran Sea (in the western Mediterranean) during June–October 1982. It was conducted to study the large anticyclonic gyre formed by the inflowing jet of low salinity Atlantic Water. The objective was to better understand the kinematics and dynamics of the gyre using numerical modeling, remote sensing, and field measurements.

An oceanographic instrument for the determination of wind stress from measurements of ambient noise.
Industry:Earth science
An oceanographic program to measure the eddy currents in the North Atlantic Equatorial Current for several months using moored current meters and hydrographic surveys. This was a program carried out in 1970 by the Soviet Union.

An ONR research program primarily directed toward improvement of the description of the subtropical South Atlantic. It focused on the poleward corners of the subtropical gyre, i.e. the separation of the Brazil Current and its confluence with the Malvinas or Falkland Current in the southwest, and the Agulhas Retroflection and Benguela Current in the southeast.

An ONR sponsored joint operation between the NRL Acoustic Signal Processing Branch and Woods Hole. The goal is to explore the effects on acoustic propagation of random ocean environments in the water column and the bottom sediments. The experiment was performed on the continental shelf about 100 miles of the coast of New Jersey in the Hudson Canyon area in July–August 1995, and deployed a significant number of acoustic and oceanographic equipment to characterize the acoustic propagation environment.
Industry:Earth science
An open international forum of research ship operators from 14 countries and representatives of EC, FAO and OCEANIC who meet annually to discuss research fleet barter/exchange arrangements and research fleet status as well as report on staff exchanges and lost equipment.
Industry:Earth science
An open ocean undulating data acquisition vehicle originally designed and built by the Institute of Oceanographic Sciences (now the Southampton Oceanography Center, UK). SeaSoar is capable of undulating from the surface to 500 m at tow speeds of up to 12 knots (with a faired cable) following a controlled and adjustable undulating path through the ocean. Data obtained from sensors mounted in SeaSoar are transmitted to the towing vessel via a multi–core tow cable.
Industry:Earth science
An opening in pack ice which forms as the result of a local divergence in its drift. These occur at weak points in the ice and are characteristically long, narrow channels meters to hundreds of meters wide and kilometers to tens of kilometers long. They have no fixed location, although their occurrence may be predictable by region or season, and the are more prevalent in regions of thinner ice and marginal ice zones. Leads typically cover at least 1% of the total ice area, with the average distance between them varying from 5 km in the marginal ice zone to 275 in the central Arctic pack ice. A lead is defined by the WMO as: Any fracture or passage-way through sea ice which is navigable by surface vessels.
Industry:Earth science
An orbit in which a satellite passes directly over or close to the poles. The characteristic orbital period is around 90 minutes at an altitude of between 500 and 1500 km. Such satellites are usually Sun synchronoussunsynchronous, and have a field of view such that it takes about 15 orbits to cover the globe, with a specific location being seen about twice a day.
Industry:Earth science
An organization created to advanced sea surface state models.
