Salinity sensors

Electrode Conductivity principle

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. More..

Welcome to the Coastal Wiki, your guide to coastal knowledge and experience
You may find information on any coastal topic by entering a corresponding term in the search window. “Go” will direct you to an article with this title (if such an article exists); “Search” will provide an overview of articles in which your search term appears. You will find an explanation of coastal terms and concepts in the Glossary.

We also invite coastal and marine practitioners, policymakers and scientists to make a contribution to this new concept in sharing European knowledge and experience in integrated coastal zone management. You may contribute in several ways: you may improve or update an existing article, you may add a discussion page to an existing article or you may add a new topic.

How to contribute to the Coastal Wiki
You have unrestricted access to the Coastal Wiki. But for adding or editing articles an authorisation is required. This is a major difference with the general wikipedia. For obtaining an editing authorisation you may contact your national coordination office. You will receive a request to provide contact information for the Wiki Contact Database. Anonymous contributions to the Coastal Wiki are precluded. Authors, co-authors and editors of articles are explicitly acknowledged. Your contribution will be reviewed by the coordinator of the theme where your article best fits. The theme coordinators also check that your contribution is adequately linked to existing articles on similar or related topics.

You should remember that the Coastal Wiki is primarily meant for disseminating knowledge to a broader audience than the circles of specialists working at the frontiers of science. It is not meant for publishing original research; it is a vehicle for disseminating knowledge complementary to the traditional peer-reviewed scientific journals. Please read the Basic setup, rules and guidelines and How to edit an article before you start writing an article.
