Salinity

The number of grams of salt per thousand grams of sea water, usually expressed in parts per thousand.

Glossary of Terms

Lands whose saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities that live in the soil and on its surface (e.g. Mangrove forests).

Scarp, beach

An almost vertical slope along the beach caused by erosion by wave action. It may vary in height from a few cm to a metre or so, depending on wave action and the nature and composition of the beach.

A steep slope, usually along the foreshore and/or at the vegetation line formed by wave attack.

Mud

A fluid-to-plastic mixture of finely divided particles of solid material and water.

Longshore Transport

Sediment transport down the beach (parallel to the shoreline) caused by longshore currents and/or waves approaching obliquely to the shoreline.

Wave Propagation

The transmission of waves through water.

Reference Station

A place for which tidal constants have previously been determined and which is used as a standard for the comparison observations at a second station.

A station for which independent daily predictions are given in the tide or current tables from which corresponding predictions are obtained for other stations by means of differences or factors.
