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 ...
Killworth and Edwards (1999) review the use of these in numerical ocean models and present another model.

Krill and Environment, a study conducted off east Antarctica in the Austral summer of 1995–96. The primary focus was to describe the distribution and abundance of Antarctic krill and to determine possible sources of Antarctic bottom water in the region.

Large semipermanent belts of high or low sea level pressure distributed around the Earth that largely control the general circulation of the atmosphere and the concomitant long-term weather patterns. The term was originally used by Teisserenc de Bort in 1881 to describe maxima and minima of pressure on daily charts, but has evolved to have the more global meaning. These centers include the Icelandic Low, the Aleutian Low, the Pacific High, the Azores High, the Siberian High, and the Asiatic Low.

Large, solitary meanders in the path of the Agulhas Current between Cape St. Lucia and the Agulhas Bank south of Africa. The pulses seem to originate in the region of the Natal Bight, a distinct offset in the coastline north of Durban. They manifest themselves as a cyclonic eddy in the current, move downstream at 10–20 km per day, and have diameters ranging from 30 to 200 km (growing steadily in size as they move downstream). It has been suggested that the Pulse may play a central role in the upstream retroflection of the Agulhas Current, and in the shedding of eddies from the seaward side of the current.

Lines joining the points where high water occurs at the same time. The lines show the lapse of time between the moon’s transit over a reference meridian (usually the Greenwich meridian) and the occurrence of high water for any point lying on the line.

Living upon the high seas as opposed to living in coastal waters, i.e. neritic.

MArine and TErrestrial data for the North Atlantic region from 25 to 9 ka BP. The goal of this INQUA project is to integrate data sets from ice-core, marine and land records to produce a series of paleoenvironmental maps for the interval between the Last Glacial Maximum and the Early Holocene. The primary objective is to study the ice-sealand- atmosphere interactions and the feedbacks operating during a glacial-interglacial transition.

Marine organisms associated with the water surface or the uppermost water layer that possess special adaptations allowing them to passively float there. This term was originally used in freshwater biology to refer to microscopic plants and animals associated with the surface film and supported by surface tension, but it is now also used by marine biologists to describe organisms found in the upper 100 meters of the ocean. Pleuston was historically used especially by Soviet scientists, with their western counterparts more likely to group the pleuston in with the neuston.

Models of the surface layer of the ocean can be classified into two groups: differential models and depth–integrated bulk models. The bulk models originate with Kraus and Turner (1967), and are developed by integrating the heat and energy conservation equations over the mixed layer. These models are limited by the assumptions used in the model formulations, two notable ones being that (i) a well–mixed layer exists a priori and (ii) there is a density discontinuity at the base of the mixed layer. The differential models can be traced to the paper of Mellor and Yamada (1974) on turbulent closure models for boundary layers. These are useful but limited by substantial computational requirements.
