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 series of 1:250,000 maps of the bathymetric, geological and geophysical characteristics of the Mediterrean Sea area. This is an activity of the IOC.
Industry:Earth science
A series of field experiments at different ocean sites to obtain a comprehensive set of bio-optical measurements such as radiometry, pigment analysis, total suspended matter, beam transmittance, and physical properties.
Industry:Earth science
A series of research cruises in 1965-1966 that performed tightly organized surveys of the tropical Atlantic. Simultaneous data on temperature, salinity and currents were obtained for the then little-known area off the west coast of Africa. These cruises were done with ships from the U.S., the Soviet Union, France, Brazil and other nations.
Industry:Earth science
A series of satellites designed exclusively for geodetic studies. They were flown as part of the National Geodetic Satellite Program. The instrumentation varied with each mission. The objectives were to:
locate observation points (geodetic control stations) in a 3–D earth center–of–mass coordinate system within 10 m of accuracy;
determine the structure of the earth’s gravity field to 5 parts in 10 million;
define the structure of the earth’s irregular gravitational field and refine the locations and magnitudes of the large anomalies; and
compare results of the various systems on board the spacecraft to determine the most accurate and reliable system.

A series of three cruises taking place aboard the RV Marion Dufresne from 1985-1987. The INDIGO 14C activities69 are available from the CDIAC.
Industry:Earth science
A series of wavemodels, i.e.
WAVEWATCH I, developed at Delft University (Tolman (1991)),
WAVEWATCH II, developed at NASA GSFC (Tolman (1992)), and
WAVEWATCH III, developed at NOAA/NCEP. WAVEWATCH III is a third–generation wave model that solves the spectral action density balance equation for wavenumber–direction spectra. It is implicitly assumed that the medium (i.e. depth and current) as well as the wave field vary on time and space scales much larger than the corresponding scales of a single wave. The source code and complete documentation are available for WAVEWATCH III.
Industry:Earth science
A set of equations developed using the quasi-geostrophic approximation. These are formally valid only when the planetary vorticity is large compared to the relative vorticity of the fluid, when the variation in the Coriolis parameter over the domain is small compared to its mean value, and when free surface and topographic fluctuations are both much smaller than the average fluid depth.
Industry:Earth science
A set of filtered equations obtained from the fundamental equations of motion of a fluid by applying the hydrostatic approximation and neglecting the viscosity. They comprise three prognostic and three diagnostic equations, the former of which are the x and y (or horizontal) components of the momentum equation and the thermodynamic equation of energy, and the latter the continuity equation, the hydrostatic equation and the equation of state. These equations form a closed set in the dependent variables which are the three components of velocity, pressure, density and temperature. The PEs filter out vertically propagating sound waves.
Industry:Earth science
A set of filtered equations to the equations of motion governing atmospheric or oceanic flow, the chief of which is the vorticity equation. In this, the horizontal wind is replaced by the geostrophic wind in the term representing the vorticity but not in the term representing the divergence.
Industry:Earth science
A set of tables compiled by E. C. Lafond for the purpose of correcting reversing thermometers and computing dynamic height anomalies. These were published by the U.S. Navy Hydrographic Office as H. O. Pub. No. 617.
