Industry:Earth science
A movement of ocean water characterized by regularity, either of a cylic nature, or more commonly as a continuous stream flowing along a definable path. Three general classes, by cause may be distinguished: ( a) currents related to sea water density gradients, comprising the various types of gradient current ; ( b) wind-driven currents , which are those directly produced by the stress exerted by the wind upon the ocean surface; ( c) currents produced by long-wave motions. The latter are principally tidal currents , but may include currents associated with internal waves , tsunamis , and seiches . The major ocean currents are of continuous, stream-flow character, and are of first-order importance in the maintenance of the earth's thermodynamic balance.
Industry:Earth science
A measure of the intensity of radiation thermally emitted by an object, given in units of temperature because there is a proportional correlation between the intensity of the radiation emitted and physical temperature of the radiating body.

Un movimento di acqua dell'oceano, caratterizzata dalla regolarità, sia di natura cylic, o più comunemente come un flusso continuo che scorre lungo un percorso definibile. Tre classi generali, di causa possono essere distinti: (a) correnti legate a gradienti di densità acqua mare, composto da vari tipi di gradiente corrente; (b) correnti wind-driven, che sono quelle prodotte direttamente da stress esercitate dal vento sulla superficie del mare; (c) correnti prodotte da moti di onde lunghe. Questi ultimi sono principalmente correnti di marea, ma possono includere correnti associate seiches, tsunami e le onde interne. Le correnti oceaniche principali sono di carattere di flusso-flusso continuo e sono di importanza di primo ordine nel mantenimento dell'equilibrio termodinamico della terra.
Industry:Earth science
Un pluriennale accumulo surplus di nevicata, eccesso di neve sciogliere sulla terra e conseguente a una massa di ghiaccio almeno 0. 1 km2 nella zona che mostra alcune prove di movimento in risposta alla gravità. Un ghiacciaio può terminare a terra o in acqua. Ghiaccio del ghiacciaio è il più grande serbatoio di acqua dolce sulla terra e la seconda solo agli oceani come il più grande serbatoio di acqua totale. Ghiacciai si trovano in tutti i continenti tranne l'Australia.
Industry:Earth science
A nautical unit of horizontal distance, equal to 600 feet (100 fathoms ) and approximately one-tenth of a nautical mile .
Industry:Earth science
A method of determining water depths by measuring the time lapse between the generation of an initial sound pulse on the ship and the return of the echo. With knowledge of the speed of sound in water, the depth of water can be calculated.
Industry:Earth science
A collection of waves the amplitudes of which are largest for waves with frequency and wavelength in a range about some central frequency and wavelength.
Industry:Earth science
A remote sensing instrument capable of identifying sub-surface archaeological features by measuring the difference in their magnetic properties against the surrounding soils.
Industry:Earth science
A contour of equal depth in a body of water, represented on a bathymetric chart.
