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 study of the physical and thermodynamic properties of the atmosphere. The properties mainly of concern are dry-bulb temperature, wet-bulb temperature, dew-point temperature, absolute humidity, relative (or percent) humidity, sensible heat, latent heat, enthalpy (or total heat), density and pressure.
Industry:Earth science
The study of the spatial distribution of ancient organisms, including analysis of the ecological and historical factors governing this distribution. In contrast to paleoecology, most paleobiogeographical studies have dealt with distributions of individual taxa or with questions of global or regional provincialism.
Industry:Earth science
The sum of the large-scale velocity and the eddy-induced transport velocity. This is velocity at which tracers are advected in large-scale circulation models.
Industry:Earth science
The suspended particle load that controls the chemistry of the oceans. The physical and chemical properties of the particles control how rapidly a chemical species is removed from solution and incorporated in sediment. The four main sources of this in the oceans are: (1) fluvial input of terrigenic material; (2) aeolian input from wind erosion of continental masses, volcanism and anthropogenic sources; (3) resuspension of sedimentary material by current erosion, earthquakes and slumping; and (4) authigenic production by biota, submarine volcanism and the precipitation of inorganic minerals.
Industry:Earth science
The temperature lapse rate of air which is undergoing a reversible natural adiabatic process. Abbreviated SALR.
Industry:Earth science
The temperature obtained by covering the bulb of a dry-bulb thermometer with a silk or cotton wick saturated with distilled water and drawing air over it at a velocity not less than 1000 ft/min. This is often accomplished by swinging the covered thermometer on the end of a string or rope. If the atmosphere is saturated with water vapor, the water in the wick will not evaporate and the dry and wet bulb temperatures will be the same. If the atmosphere is not completely saturated, the water will evaporate from the wick at a rate depedent upon the degree of saturation. The evaporation will cool the bulb and lower the temperature reading over that of the dry-bulb temperature to that of the wet-bulb temperature.
Industry:Earth science
The theoretical maximum amount of water vapor that can be convyed to the atmosphere by the combined processes of evaporation and transpiration by a surface covered by green vegetation with no lack of available water in the soil.
Industry:Earth science
The theory that changes in the geographic distribution of solar insolation due to planetary perturbations of the Earth’s orbital characteristics are the primary driving force for the cycles of glaciation seen in geological and fossil records.
Industry:Earth science
The tidal current existing during any time the height of the tide is decreasing. These generally flow in a seaward direction. This has been erroneously called ebb tide.
Industry:Earth science
The tide created in an estuary caused by the ocean tide at the entrance to the estuary acting as a driving force.
