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 ...
That part of a boundary layer where the viscous stress and the Reynolds stress have the same order of magnitude and the linear velocity profile turns smoothly into the logarithmic profile.
Industry:Earth science
In physical oceanography, a phenomenon that occurs when two water masses with identical densities but different temperatures and salinities mix to form a third water mass with a greater density than either of its constituents. This is hypothesized to be a major cause of sinking in high northern latitudes.
Industry:Earth science
A fine-grained, deep-sea deposit of pelagic origin containing more than 30% calcium carbonate derived from the skeletal material of various plankton. It is the most extensive deposit on the ocean floor but restricted to depths less than about 3500 m due to the carbon compensation depth.
Industry:Earth science
A soft, siliceous, deep-sea deposit of which more than 30% is composed of silica-rich diatom cell walls. This type of siliceous ooze (another of which is radiolarian ooze) predominates in high latitudes around the coast of Antarctica and in the North Pacific, but is overwhelmed by sediment of continental origin in the North Atlantic. This type of ooze covers about 9% of the sea floor. Compare to calcareous ooze.

A graph showing the dependence of the frequency on the wavenumber for dispersive waves. This is usually created by first using a dispersion relation to obtain frequency/wavenumbers pairs, and then plotting them.

In physical oceanography, this refers to the difference in the molecular diffusion rates of heat and salt in sea water, the molecular diffusion rate of heat being about 100 times that of salt. If two water masses with the same density but different combinations of temperature and salinity are in contact, the double (or differential) diffusion can give rise to density changes that render the layers unstable. Two phenomena that are possible consequences of this are double diffusive instability and layering.
Industry:Earth science
In oceanography, a field of horizontally varying dynamic heights in the ocean, analogous to, for example, a topography field on land. This is also called geopotential topography.
Industry:Earth science
EOF analysis provides a convenient method for studying the spatial and temporal variability of long time series of data over large areas. It splits the temporal variance of the data into orthogonal spatial patterns called empirical eigenvectors. A set of orthogonal spatial modes can be identified such that, when ordered, each successive eigenvector explains the maximum amount possible of the remaining variance in the data, and each eigenvector pattern is associated with a series of time coefficients that describe the time evolution of the particular spatial mode. The modes are orthogonal, which means that any two modes are uncorrelated in space and time and, as such, no one mode is related to any other.
Industry:Earth science
A shallow inland sea with limited connection to the open ocean and having depths less than 250 meters.
Industry:Earth science
The layer of water above the thermocline in a fresh water lake, as opposed to the hypolimnion. This is equivalent to the mixed layer in the ocean.
