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 experiment conducted off the coast of California in 1990 and concerned with wave breaking and the interaction between surface waves and upper ocean boundary layer dynamics. The scientific goals were to improve the understanding of processes involved in wave breaking (e.g. what determines the occurrence of breaking in space and time, the processes of bubble and fluid injection, the generation of turbulence in the upper layer of the ocean by waves) and in determining the structure of the upper ocean (e.g. the role of surface waves in air-sea transfers and in mixed layer dynamics, with particular emphasis on the structure and dynamics of Langmuir circulation.

An experiment conducted over the tropical oceanic area north of Australia in Jan.-Feb. 1987. It explored the vertical air motions and other kinematic properties of tropical mesocale convective-cloud systems by direct aircraft penetration. The objectives of EMEX were to document, as intensively and directly as possible, the vertical profile of vertical velocity and other kinematic structures over the ocean near the equator with the most up-to-date instrumentation available and to investigate the physical mechanisms responsible for the convective and stratiform components of the observed cloud systems.

An experiment performed in the fall of 1990 off the coast of Virginia which was primarily concerned with the evolution of the directional wave spectrum, wind forcing and wave dissipation, the effect of waves on air-sea coupling mechanisms, and the microwave radar response of the ocean surface. The scientific goals were to understand the dynamics of the evolution of the wave field in the open ocean; to determine the effect of waves on the air-sea transfers of momentum, heat and mass; to explore the response of the upper mixed layer to atmospheric forcing; to investigate the effect of waves on the response of various airborne microwave systems; and to improve numerical wave modeling.

An experiment planned by JAMSTEC to start in around 2006. The plan is to make tomographic observations of the North Equatorial Current bifurcation region in the Philippine Sea after the conclusion of the KESS program.
Industry:Earth science
An experiment scheduled to take place from Feb.-Mar. 1997 whose aim is to advance the understanding and prediction of wintertime, oceanic, extra-tropical weather systems. It is designed to improve the forecasting of North Atlantic storms.
Industry:Earth science
An experiment taking place during the summer of 1996 and the winter/early spring of 1997 that focused on the shelfbreak front just south of Cape Code on Nantucket Shoals.
Industry:Earth science
An experiment taking place in October 1993 that marked the first attempt to experimentally manipulate an ocean ecosystem. A single pulse of iron was added to a 64 square kilometer patch of water in the eastern equatorial Pacific HNLC zone. The fertilized patch was tracked using a Chl fluorescence and a sulfur-hexafluoride (SF6) inert tracer. After 2 to 3 days researchers measured a doubling of phytoplankton biomass, a tripling of Chl, and a fourfold increase in net primary productivity (NPP), with no measureable drawdown of either NO3 or CO2.
Industry:Earth science
An experiment taking place in the Pacific subarctic frontal zone in 1987.
Industry:Earth science
An experiment that took place in the east–central Atlantic Ocean in March 1992 between 20–35° N and 35–10° W.
Industry:Earth science
An experiment that took place in the northern Canary Basin from July to November 1993. A large data set was obtained from three hydrographic arrays, current meter moorings, surface drifters drogued at 150 m, and 2000 m deep RAFOS floats.
