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 ...
The tides produced when the gravitational pull of the Sun is in quadrature, i.e. at right angles to, with that of the Moon. These occur twice a month at about the times of the first and last quarters. In these situations the gravitational pull of the Sun/Moon produces high/low water or vice-versa, and as such the differences between high and low tides are unusually small, with both the high tide lower and the low tide higher than usual. The tidal height is about .375 that of maximum during neap tides.

The time interval between the transit of the moon over either the local or Greenwich meridian and the next lower high water (LHW). This is generally used when the diurnal inequality is large.

The trade winds, or tropical easterlies, are the winds which diverge from the subtropical high-pressure belts, centered at 3-40° N and S, towards to equator, from north to east in the northern hemisphere and south to east in the southern hemisphere.

The Turbulence andWaves over Irregularly Sloping Topography Experiment is a WHOI program to discover what dictates the magnitude, frequency and spatial scales of internal waves in continental slope regions. The study area is on the continental slope of the North Atlantic Ocean near Norfolk Canyon. The area is centered at 37.25°N and 74.66° W and was chosen for the evenly spaced topographic waves that run orthogonal to the slope. In the deployment phase, planned to last from May 10 to June 8, 1998, three Moored Profilers (MP) will be deployed in a closely spaced array (about 500 m separation). This should allow the assessment of horizontal internal wave scales. High Resolution Profiler (HRP) dives will also be made to quantify the smallest scale components of vertical mixing.

The U.K. contribution to LOICZ. The project aims to quantify and simulate the fluxes and transformations of materials, e.g. sediments, nutrients, contaminants, into and out of the coastal zone, extending from the catchment to the edge of the continental shelf. The main study area is the U.K. East Coast from Berwick upon Tweed to Great Yarmouth, concentrating on the Humber River and its catchment.

The United Nations declared 1998 to be the International Year of the Ocean with the overall objective being to focus and reinforce the attention of the public, governments and decision makers at large on the importance of the oceans and the marine environment as resources for sustainable development.

The upper layer of the ocean as defined by Defant in 1928. The troposphere is a region of relatively high temperature where there are strong vertical and horizontal variations of properties. It is a zone of perturbations and strong currents.

The uptake of ammonium by phytoplankton in the euphotic zone. It is so-called because ammonium is a product of internal processes within the euphotic zone and it is therefore recycled or regenerated nitrogen.

The use of a radiometer to quantitatively describe the power from a specific light field. The description can be made in terms of several properties including magnitude, geometrical distribution (or direction), spectral distribution, state of polarization, and time variability. Before the advent of satellite oceanography, the primary use of radiometry was to sample the radiant power in the vicinity of an organism to obtain quantitative information about how it reacts to light. Now the use of radiometers in instruments aboard satellites to measure various properties of incident, reflected and emitted radiation is nearly ubiquitous, with new types of radiometers seemingly developed for each new mission.
