sound channel
Earth science; Physical oceanography
A narrow channel in which sound waves can be effectively trapped. A region of minimum sound speed is created where the bottom of the thermocline meets the top of the deep ...
Drake Passage
Earth science; Physical oceanography
A narrow constriction between South America and Antarctica between 56 and 63° S through which the Antarctic Circumpolar Current (ACC) must accelerate and squeeze in its trip ...
Intertropical Convergence Zone
Earth science; Physical oceanography
A narrow low-latitude zone in which air masses originating in the northern and southern hemispheres converge and generally produce cloudy, showery weather. Over the Atlantic and ...
rip current
Earth science; Physical oceanography
A narrow seaward return flow caused by waves breaking in the surf zone and piling up water against the coast. This establishes a hydraulic head which, combined with bathymetric ...
SEASAT
Earth science; Physical oceanography
A NASA satellite that operated from June 1978 to October 1978. Instruments on board included SASS, an altimeter, SMMR, a microwave SAR, and VIRR. The altimeter was an active radar ...
