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 name given to about eight species of seaweed that float in clumps and long windrows in the Sargasso Sea. It was so named by Portuguese sailors who followed the voyages of Columbus through the region and noticed the resemblance of the small air bladders that allow Sargassum to float to a type of grape called Salgazo.

The name given to the atmospheric component of the El Nino/Southern Oscillation (or ENSO) phenomenon. The SO is a large-scale shift in atmospheric mass between the western and eastern Pacific, monitored by computing the SOI. An SOI indicating El Nino conditions means that there is reduced rainfall over the Indonesian region and that the west Pacific convective center is displaced eastward along the equator.
Industry:Earth science
The name given to the changes in the amount or seasonal distribution of solar radiation that reaches the Earth as caused by the orbital changes predicted by Milankovitch theory.
Industry:Earth science
The name given to the cycling of CaCO3 in the ocean. Plants and animals living in the euphotic zone have CaCO3 skeletons (tests) which they precipitate from dissolved calcium and carbonate ions. The CaCO3 formed this way eventually sinks and is dissolved back to calcium and carbonate ions in the deeper parts of the water column and in the sediments. The ocean circulation closes the loop by transporting the ions back to the surface waters. This pump creates a surface depletion and a deep enrichment of both DIC and alkalinity. An increase in the strength of this pump will serve to increase atmospheric CO2 since the pump variations have twice as great an effect on alkalinity as on DIC.

The name given to the region in the Southern Ocean between the Subantarctic Front to the south and the Subtropical Front to the north. This zone is characterized by the presence of SAUW at and near the surface. The SAZ is one of four distinct surface water mass regimes in the Southern Ocean, the others being (to the south) the Polar Frontal Zone (PFZ), the Antarctic Zone (AZ) and the Continental Zone (CZ).
Industry:Earth science
The name given to what was once thought to be a semipermanent anticyclone north of the North Brazil Current (NBC) retroflection. Better temporal and spatial sampling has shown this to be a series of eddies pinched off by the retroflection rather than a persistent feature.

The name of what is now known as the IAPSO from 1929 to 1948.

The name of what is now known as the IAPSO from 1948 to 1967.

The name sometimes given to the combination of the Chile Coastal Current (CCC) and the Peru Coastal Current (PCC).
Industry:Earth science
The narrowest of the atmospheric layers, extending from the surface of the Earth to about 10 km at the Equator and 6 km at the poles near the 200 mbar level. This layer contains about 80-85% of the atmosphere’s total mass and almost all of the water vapor and clouds. Temperatures fall with height at the rate of about 0.5° F per 100 feet. It is bounded above by the tropopause which varies with latitude and season. This layer is characterized by strong vertical mixing associated with latent heat effects and clouds.
