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 egregious misnomer for a type of wave that has nothing to do with tides or tide-producing forces. See the more apt term seismic sea wave for a description.
Industry:Earth science
An element of EOSDIS and located at JPL, is responsible for archiving and distributing data relevant to the physical state of the ocean. Most of the data archived at PODAAC is derived from sensors on satellites.
Industry:Earth science
An ENSO-related phenomenon conventionally defined as SSTs greater than or equal to 28 °C. It is a large area of heat accumulation in the global ocean and related to the development of El Nino.
Industry:Earth science
An equation expressing a correlation between deuterium and oxygen-18 in meteoric waters. The equation is expressed as del D = 8 * del oxygen-18 + 10.
Industry:Earth science
An equation with which one can determine the frequency (and thus phase speed) of waves of a given wavenumber, or occasionally vice versa.
Industry:Earth science
An equatorially trapped wave that behaves like a mixture of gravity and Rossby waves. Yanai waves exhibit an eastward group velocity at all wave numbers k, although for large positive k is behaves like a Rossby wave and for large negative k like a gravity wave. For the case k=0 it is a standing wave for which the surface moves sinusoidally up and down with opposite sign on opposite sides of the equator. Fluid particles move anticyclonically around elliptical orbits. with eastward motion when the surface is elevated and westward motion when it is depressed. To be completed.
Industry:Earth science
An error that is a function of the instrument design and the ambient conditions under which it must operate. For example, the mercury barometer for surface (not mean sea level) pressure measurements has an expected instrument error of about 0.25 mb for a single reading due to ambient temperature and wind effects.
Industry:Earth science
An EU-funded program to understand the physical and biological processes which control the population dynamics of the copepod Calanus finmarchicus, a key zooplankton species in the northeast Atlantic. A key goal is to establish the relationship between the physical and biological factors affecting annual recruitment and reproduction of the species as a step towards predicting the consequences of future climate change.
Industry:Earth science
An experiment (also called ERS–SYMPLEX) carried out in the Sicily Channel during April– May 1996 to compare sea level anomalies obtained from ERS–1/2 and TOPEX/POSEIDON altimeters with in situ data. A dense network (about 5 km spacing) of XBT and CTD casts were made along all ERS–1/2 and TOPEX/POSEIDON tracks at the same time of each satellite pass.
Industry:Earth science
An experiment conceived to provide a data base to resolve the disparity among different Synthetic Aperture Radar (SAR) ocean surface imaging theories. The specific objectives were to investigate the hydrodynamics of short waves and their modulation by long waves, to assess the assumptions stipulated in radar backscatter theory that are used in SAR ocean surface imaging, and to develop a verifiable theory for SAR imaging of the ocean surface.
