saline evaporation pond: http://purl.obolibrary.org/obo/ENVO_00000055
A shallow man-made pond designed to produce salt from sea water. The seawater is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested.
saline lake: http://purl.obolibrary.org/obo/ENVO_00000019
A lake whose water contains a considerable concentration of dissolved salts.
saline marsh: http://purl.obolibrary.org/obo/ENVO_00000054
A marsh whose water contains a considerable quantity of dissolved salts.
saline pan: http://purl.obolibrary.org/obo/ENVO_00000279
A flat expanse of ground covered with salt and other minerals, usually shining white under the sun. A salt pan is formed where water pools. A saline pan would be a lake or a pond if it were located in a climate where the rate of water evaporation were not faster than the rate of water precipitation, i.e., if it were not in a desert. If the water is unable to drain into the ground, it remains on the surface until it evaporates, leaving behind whatever minerals were dissolved. Over thousands of years, the minerals (usually salts) accumulate on the surface.

It is dominated by halophytic (salt tolerant) herbaceous plants. The daily tidal surges bring in nutrients, which tend to settle in roots of the plants within the salt marsh. The natural chemical activity of salty (or brackish) water and the tendency of algae to bloom in the shallow unshaded water also allow for great biodiversity.
