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 ...
The use of the geostrophic wind as an approximation to the actual wind in the equations of motion.
Industry:Earth science
The use of various paleoclimate proxy data to attempt to gauge paleotemperatures.
Industry:Earth science
The variability of temperature and salinity along a surface of constant density due to air–sea fluxes, turbulent mixing and advection.
Industry:Earth science
The vorticity imparted to a parcel or column of fluid by fluid motion. It is a characteristic of the kinematics of the fluid flow which expresses the tendency for portions of the fluid to rotate. Technically speaking, this is the curl of the fluid velocity vector, although in oceanography and meteorology it is usually only the vertical component of the curl of the horizontal velocity vector since all other components are usually negligible.

The Warm Ring Inertial Circle Layer Experiment took place in March 1990 in the northwest Atlantic between 37–45° N and 75–60° W. The goal of the experiment was to investigate the rates and types of mixing associated with a Gulf Stream warm core ring. A high resolution profiler (HRP) was used to complete 78 profiles in and around one warm core ring during a 21 day cruise, with the complete depth of the ring resolved by profiling to 1000 m. The HRP measurements were accompanied by 26 CTD profiles, 55 expendable current profiler (XCP) profiles, a Richardson Number float deployment, and two XBT surveys to precisely define the position of the ring.

The westward flowing current close to the Antarctic continent driven by the polar easterlies.

The zone or portion of a beach profile extending seaward from the foreshore to just beyond the breaker zone.

Then name given to the cycle of organic matter and nutrients in the ocean. Since photosynthesis exceeds respiration only in the euphotic zone, there is a net sink of CO2, phosphate and nitrate in the euphotic zone and a net source in the aphotic zone. Thus a downward flux of organic matter and an upward flux of nutrients connects the euphotic zone sink and the aphotic zone source of nutrients. This has also been called the soft tissue pump, but the present name was suggested in recognition of the possible role of dissolved organic species in the transport cycle.

These represent the relatively constant proportions maintained between the elements C, N, P and O taken up during the synthesis and released by subsequent remineralization of organic matter by marine organisms. It was originally suggested that during organic matter cycling, carbon, nitrogen, phosphorous and oxygen are cycled in the ratio C:N:P:O2 = 106:16:1:138, i.e. for every phosphate ion taken up during photosynthesis, 16 nitrate ions and 106 molecules are taken up and 138 molecules of oxygen are produced. More recent studies have modified the ratios to 140:16:1:172.

These were undertaken every three months in the equatorial Atlantic from the Brazilian coastline to the Gulf of Guineau, starting in July 1982 and ending in August 1984. Temperature, salinity, and dissolved oxygen were measured between the surface and 500 m with a CTDO system, and horizontal velocities were measured via current profiling using a free floating surface buoy. FOCAL, along with SEQUAL, amounted to the first time an equatorial ocean was fully monitored over a period of two years.
