    <skos:definition xml:lang="en">Ocean salinity is an essential climate variable within the global climate observing system, and plays important roles in ocean physics and biogeochemistry, climate variability, and the water cycle. The main goal of the NASA Ocean Salinity Science Team (OSST) is to understand the roles of ocean salinity within the Earth system. In addition to conducting the related ocean salinity science investigations, NASA OSST also retrieves and improves sea surface salinity (SSS) measurements from NASA’s Aquarius and Soil Moisture Active Passive (SMAP) satellites, and develops concepts for next-generation salinity satellites to improve global SSS measurements. NASA in-situ salinity field campaigns are part of the NASA OSST effort to use satellite and in-situ SSS measurements to enhance the knowledge of salinity processes.</skos:definition>
