Since as far as Ancient Greece times, attempts have been made to try to measure the "saltiness" of seawater. However, methods' efficiency was very incipient and their sensitivity and repeatability was very limited. During the Modern History more precise methodologies were developed: weighing after evaporation (Boyle,1693; Birch, 1965), solvent extraction (Lavoisier, 1772) and precipitation (Bergman, 1784).

In 1865, Forchhammer introduced the term salinity and dedicated himself to measure individual components of seasalt rather than the total salinity. He found that the ratio of major salts in samples of seawater from various locations was constant.

Salinity is a ratio and not a physical parameter that can be measured(under PSS-78, see box). Thus, “Salinity sensors” do not exist. What is commonly referred to as a salinity sensor is in fact a conductivity sensor.

Compendium for Coast and Sea - creating a marine science-policy interface


The Compendium for Coast and Sea is an integrated knowledge document about the socio-economic, environmental and institutional aspects of the coast and sea in Flanders and Belgium. As such, it constitutes a one-stop shop for data and information from the Flemish and Belgian marine and maritime research community and experts. The Compendium for Coast and Sea is an initiative of the Flanders Marine Institute (VLIZ) and was developed in close collaboration with experts from the research community, government, industry and civil society organisations. The first version of the Compendium was launched in 2013, a second edition was presented in 2015.
