This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh. Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as ...
Lake Van viewed from the Space Shuttle Challenger during flight STS-41-G. Southwest is at top. Prior to 2018, the only fish known to live in the brackish water of Lake Van was Alburnus tarichi or Pearl Mullet (Turkish: inci kefali), a Cyprinid fish related to chub and dace, which is caught during the spring floods.

A river or lake water with a salinity of around 70 mg/L will typically have a specific conductivity at 25 °C of between 80 and 130 μS/cm. The actual ratio depends on the ions present. [ 14 ] The actual conductivity usually changes by about 2% per degree Celsius, so the measured conductivity at 5 °C might only be in the range of 50–80 μS/cm.
T-S diagram of a station in the North Pacific. In oceanography, temperature-salinity diagrams, sometimes called T-S diagrams, are used to identify water masses.In a T-S diagram, rather than plotting each water property as a separate "profile," with pressure or depth as the vertical coordinate, potential temperature (on the vertical axis) is plotted versus salinity (on the horizontal axis).
There may exist proxies for salinity, but to date the main way that salinity has been measured has been by directly measuring chlorinity in pore fluids. [2] Adkins et al. (2002) used pore fluid chlorinity in ODP cores, with the paleo-depth estimated from nearby coral horizons. Chlorinity was measured rather than pure salinity because the major ...

In oceanography, a halocline (from Greek hals, halos 'salt' and klinein 'to slope') is a cline, a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. [1] Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification.
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. [1] Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. [1]
