, in oceanography.



independent fluctuations of the surface of the ocean or sea during a complete calm, consisting of long and sloping waves up to 10–15 m high and 300–400 m long and with phases of up to 17–20 sec. They result from the conversion of wind waves during their departure from an area of wind activity or after the dying down of winds. Waves of a swell are nearly indistinguishable in terms of size and shape. Particles of water in such waves move in regular circular orbits.


The volumetric increase of soils on being removed from their compacted beds due to an increase in void ratio.
A local enlargement or thickening in a vein or ore deposit.
A low dome or quaquaversal anticline of considerable areal extent; long and generally symmetrical waves contribute to the mixing processes in the surface layer and thus to its sound transmission properties.
Gently rising ground, or a rounded hill above the surrounding ground or ocean floor.
