The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water.

Chars are common in the low-salinity waters of the Olenyok Gulf and genetic studies were conducted on them.

For instance, the cod stocks of the Baltic Sea are adapted to low-salinity water.

Fahrbach et al. propose that low-salinity bottom water is formed near the Larsen Ice Shelf.

The freshwater inflow generates an estuarine circulation in the main channel, with low-salinity water moving outwards at the surface, and higher-salinity water flowing inwards below.

(Tisbury Great Pond would be a splendid natural laboratory for a fisheries biologist interested in measuring the bluefish's capacity to survive and thrive in low-salinity water.)

The resulting pressure gradient pushes relatively cool, low-salinity water from the Atlantic Ocean across the basin.

The Hog Island Oyster Company and two competitors raise prize-winning oysters in the pristine, low-salinity waters of Tomales Bay.

Wells in the vicinity of structures contained low-salinity water.

The water-mass characteristics vary widely because of the low-salinity waters of the southeast coasts of Korea and China.
