In this circulation type, the density-driven component dominates and two well-mixed layers are separated by a sharp halocline. The seawater entering the channel appears as a tongue or wedge.
Industry:Engineering
A series of islands that fringe, or mask, a mainland coast often known as barrier islands. The waters landward of such islands are sometimes treated as high seas enclaves or as inland waters.
Industry:Engineering
The movement of beach material in the littoral zone by waves and currents. Includes movement parallel (long shore drift) and sometimes also perpendicular (cross-shore transport) to the shore.

Industry:Engineering
The higher of the two high waters of any tidal day. The single high water occurring daily during periods when the tide is diurnal is considered to be a higher high water.
Industry:Engineering
A line on a map or chart representing points of equal elevation with relation to a datum. It is called an isobath when connecting points of equal depth below a datum. Also called depth contour.
Industry:Engineering
(1) Pattern of geographic distribution of individuals within a species. (2) Distortion of the shape of a seismic wave train or ocean wave train because of variations of velocity with frequency.
Industry:Engineering
