Increases in salinity have been observed in lakes and rivers in the United States, due to common road salt and other salt de-icers in runoff. [ 20 ] The degree of salinity in oceans is a driver of the world's ocean circulation , where density changes due to both salinity changes and temperature changes at the surface of the ocean produce ...
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
Approximately 37% of the drainage in the United States has been affected by salinization in the past century. [1] The EPA has defined two thresholds for healthy salinity levels in freshwater ecosystems: 230 mg/L Cl − for average salinity levels and 860 mg/L Cl − for acute inputs. [5]
The Caspian Sea is the world's largest lake and contains brackish water with a salinity about one-third that of normal seawater. The Caspian is famous for its peculiar animal fauna, including one of the few non-marine seals (the Caspian seal ) and the great sturgeons , a major source of caviar .
One of two salt lakes in the northern end of the Danakil Depression known as Lake Karum. A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per liter).

The Bonneville Salt Flats in Utah, where many land speed records have been set, are a well-known salt pan in the arid regions of the western United States. The Etosha pan, in the Etosha National Park in Namibia, is another prominent example of a salt pan. The Salar de Uyuni in Bolivia is the largest salt pan in the world.
A characteristic of seawater is that it is salty. Salinity is usually measured in parts per thousand (‰ or per mil), and the open ocean has about 35 grams (1.2 oz) solids per litre, a salinity of 35 ‰. The Mediterranean Sea is slightly higher at 38 ‰, [22] while the salinity of the northern Red Sea can reach 41‰. [23]
