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 tool to analyze the water mass mixture in a water sample by calculating the contributions from the original water masses (the source water masses) to the sample. OMP is based on a simple linear mixing model that assumes all water mass properties undergo the same mixing processes, i.e. their mixing coefficients are identical. This allows their distribution is space to be determined via a linear set of mixing equations. Mathematically speaking, OMP is an inversion of an overdetermined system performed individually for each observation point. The source water type contributions for each data point are obtained by finding the best linear mixing combination in parameter space defined by temperature, salinity, oxygen, nutrients and other water mass properties that minimizes the resisuals in a non–negative least squares sense.

A transition water mass found between the overlying Levantine Intermediate Water (LIW) and the underlying Eastern Mediterranean Deep Water (EMDW) in the eastern Mediterranean Sea. The TMW is relatively colder (14.25°C) and slightly less saline (38.88– 38.90) than LIW.

A two year Woods Hole study beginning in 1983 designed to acquire and analyze a continuous set of measurements of currents and temperatures throughout the water column in the open ocean. A total of ten moorings were deployed in about 5365 meters of water near 33deg N, 70deg W.
Industry:Earth science
A two-dimensional fluid flow theorem that states that geostrophic motion of a homogeneous fluid will be the same in all planes perpendicular to the axis of rotation. This has also been known as the Proudman-Taylor, Proudman or Taylor theorem.
Industry:Earth science
A type of bottom sampler used in biological oceanography to for the quantitative investigation of benthic organisms in relatively shallow waters. It comprises a set of heavy hinged jaws that are held open during descent but are released when the device hits bottom. The jaws close on an area of benthic material (usually around 0.1 m2) when the cable is drawn tight and the device returned to the surface. The organisms thus caught are screened from the bottom sediments, classifed and counted to develop statistics for organisms per square meter in the study area.
Industry:Earth science
A type of calcareous ooze composed of the shells of unicellular creatures called globigerina that live in the waters of warmer ocean regions. These oozes are seldom found above 5000 m depth and cover about 35% of the surface of the sea floor.
Industry:Earth science
A type of cloud hypothesized to form when water vapor within jet aircraft plumes undergoes homogeneous and/or heterogeneous nucleation processes upon which ice particles form and grow. They persist for only a short time if the ambient air is dry, but may last for minutes to hours and spread into linear formations a few kilometers in width and tens of kilometers in width if humid conditions prevail. They also tend to cluster in groups. Various investigations attempting to show a connection between them have at least showed a correlation between increased use of jet fuel in some regions and the average annual number of clear days.
