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 ridge located at approximately 75° E in the Southern Ocean that impedes the flow of the Antarctic Circumpolar Current at depths below 2000 m. Most of this broad plateau is between 2000 and 3000 m deep with some flow occurring below 3000 m in a narrow gap between itself and Antarctica.

A ridge of sand running roughly parallel to the shoreline which may become exposed at low tide. There can be a series of these running parallel to one another at different water depths.

A rotor originally developed for power generation (i.e. it’s a propellor in reverse that spins when placed in moving water) that has been extensively used as a sensor on various ocean current meters. Its advantages are that it is rugged, omni-directional and linear in steady flow, but its response to time-varying flow and susceptibility to contamination by vertical flows make it unsuitable for measurements near the surface where wave action creates both time-varying and vertical flow fields.

A Russian remote sensing module (named for the Russian word for nature) planned to provide the experimental basis for a scientific research program for the development and verification of remote sensing methods and investigations of regional and global problems in climatology, oceanography, and ecology. The module carries optical and infrared scanners, an imaging spectrometer, a LIDAR, scanning and pointing microwave radiometers, SAR, and high resolution digital (stereo) cameras. The launch data for PRIRODA is March 1996 and the operation is expected to cover 1996–97. This mission is conducted by the Russian Space Agency (RKA).

A satellite SST data set derived from the TIROS-N/NOAA series satellite AVHRR. SST estimates are obtained from AVHRR radiances by first using radiative transfer theory to correct for the effects of the atmosphere on the observations. This is done in so–called windows of the spectrum where little or no atmospheric absorption occurs. Channel radiances are transformed (through the use of the Planck function) to units of temperature, and then compared to a prior temperatures measured at the sruface. This yields coefficient which, when applied to AVHRR data, provide SST estimates with a nominal accuracy of 0.3°C.

A scheme for classifying the optical properties of various waters based on their irradiance transmissivity in the upper 10 m. The scheme divides them into oceanic (Types I to III) and coastal (Types 1 to 9) categories.

A scientific collaboration between the U.S., China, Korea, Japan, Taiwan, Russia and Singapore. The ASIAEx major field experiments began in 2000, one focusing on acoustic bottom reverberation and the other on acoustic cross–shelf progagation.
Industry:Earth science
A scientific research program built around a family of core projects whose mission is to deliver scientific knowledge to help human societies develop in harmony with Earth’s environment. The core projects are:
BAHC (Biospheric Aspects of the Hydrological Cycle);
GAIM (Global Analysis, Integration and Modeling);
GCTE (Global Change and Terrestrial Ecosystems);
GLOBEC (Global Ocean Ecosystem Dynamics);
IGAC (International Global Atmospheric Chemistry);
IGBP–DIS (Data and Information Services);
JGOFS (Joint Global Ocean Flux Study);
LOICZ (Land–Ocean Interactions in the Coastal Zone);
LUCC (Land–Use and Land–Cover Change);
PAGES (Past Global Changes);
START (System for Analysis, Research and Training);
Industry:Earth science
A sea ice process defined by the WMO as: Pressure process whereby one piece of ice overrides another. Most common in new ice and young ice. 354 A type called “finger rafting” involves the formation of interlocking thrusts, with each floe thrusting “fingers” alternately over and under each other. This is commonly found in nilas and grey ice.
