Salinity in saltwater is a measurement of salts dissolved in water that come from rocks and soil. The average salinity of the ocean is 35 ppt (parts per thousand).
Outside of the laboratory, salinity is most commonly measured by aquarium hobbyists and farmers concerned about possible salt buildup in the soil.
May 8, 2014 salinity is the measure of dissolved salt content in water. Salinity is typically measured in parts per thousand (ppt) or specific gravity (sg).
Salinity is a true measurement of the concentration of salt in the ocean and is the generally accepted standard salinity for natural seawater, (nsw), is 35ppt.
Salinity, temperature and pressure are parameters which govern the oceanographic state of a marine water body and together they make up density of seawater.
Microsiemens per centimeter is the standard unit for freshwater measurements.
Salinity is simply a measure of the amount of salts dissolved in water.
Excerpt from measurement of salinity of sea water two inexpensive methods have been found that are satisfactory. When the motion of the ship is not great, hydrometers of good quality that have been calibrated have been found to give satisfactory results when properly used; and for use in any ordinary weather suitable for hydrography a chemical titration method has been worked out that requires.
This website is about the laboratory measurements of seawater salinity – the most interesting and fundamental physical property of the seawater. Despite the great progress achieved for the last 50 years in the development of the in situ measuring salinity ctd systems, laboratory salinometers are still in service by oceanographers.
Salinity is the measurement of the total dissolved materials in a solution.

Measuring the salinity or the dissolved salt content of water is important as aquatic organisms, livestock, and crops thrive at different salinity levels. Salinity is the measure of the amount of dissolved salts in water.
Sea water salinity is expressed as a ratio of salt (in grams) to liter of water. Locked into a crystalline structure with a resulting nine percent expansion in size.
Seawater - seawater - salinity distribution: a discussion of salinity, the salt content of the oceans, requires an understanding of two important concepts: (1) the present-day oceans are considered to be in a steady state, receiving as much salt as they lose, and (2) the oceans have been mixed over such a long time period that the composition of sea salt is the same everywhere in the open ocean.
