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 narrow low-latitude zone in which air masses originating in the northern and southern hemispheres converge and generally produce cloudy, showery weather. Over the Atlantic and Pacific it is the boundary between the northeast and southeast trade winds. The mean position is somewhat north of the equator, but over the continents the range of motion is considerable. Often abbreviated as ITCZ.
Industry:Earth science
A narrow seaward return flow caused by waves breaking in the surf zone and piling up water against the coast. This establishes a hydraulic head which, combined with bathymetric irregularities along the coast, causes the narrow seaward flow.

A NASA satellite that operated from June 1978 to October 1978. Instruments on board included SASS, an altimeter, SMMR, a microwave SAR, and VIRR. The altimeter was an active radar altimeter which produced earth location and time-tagged satellite heights, significant wave heights, and geoid information. The SAR produced 25 meter resolution surface roughness imagery on a 100 km wide ground swath.

A national agency of Ireland whose mission is to undertake, coordinate, promote and assist in marine research and development and provide such services related to ma rine research and development that, in the opinion of the institute, will promote economic development and create employment and protect the environment.

A network of automatic data buoys for monitoring synoptic-scale fields of pressure, temperature and ice motion throughout the Arctic Basin. See the IABP Web site59.
Industry:Earth science
A network of seismographs across the Pacific Ocean to serve as an early warning system against the arrival of seismic sea waves (SSW) (also called tsunamis or, in an egregious misnomer, tidal waves). The SSWWS was established in 1946 after a particularly destructive SSW originating at Unimak, Alaska struck Hawaii and killed 159 people. Its headquarters are in Honolulu, Hawaii and it is operated by the Coast and Geodetic Survey of the U.S. Dept. of Commerce.

A network of water level measurement stations in the U.S. coastal ocean, including the Great Lakes and connecting waterways, and in U.S. Trust Territories and Possessions. This is administered by OLLD through the National Water Level Program. The NWLON consists of about 140 continuously operating stations in U.S. tidal regions, 49 continuously operating stations in the Great Lakes, and about 50 temporary stations operated each year in support of NOS mapping, charting, and hydrography and Great Lakes water resources management.

A neutrally buoyant float used as a subsurface drifter to study mesoscale circulation and small-scale motions in the oceans. Swallow floats approximately track isobaric surfaces, and as such are not strictly Lagrangian followers of water parcels. Rossby et al. (1985) describe a modified version of the float that follows isopycnal rather than isobaric surfaces, and thus better approximates Lagrangian motion. This is accomplished by the addition of a compressor within the float that adjusts its effective compressibility to approximate that of seawater.

A NOAA AOML program whose objectives are to: (1) described mixed– layer velocity on a 5 degree resolution global basis and produce new charts of seasonal surface circulation; (2) provide an operational data stream for SST, sea level pressure, and surface velocity data; (3) verify global climate models; (4) compute single particle diffusivities, eddy statistics, and interannual to annual variability; (5) construct models of wind–driven currents; and (6) obtain high resolution coverage in special regions for process studies. The program was started in 1978.

A NOAA CMDL program whose goal was to determine the atmospheric mixing ratio of HCFC-22 and its partial pressure in surface waters of the Western Pacific Ocean and to assess the possible existence of an oceanic sink for this compound. This cruise took twelve weeks aboard the RV John V. Vickers in 1992, beginning at Long Beach, California and ending at Noumea, New Caledonia.
