How do oceanographers measure the salinity of ocean water? Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter. WebThese two factors led oceanographers to adopt a density unit called sigma- t ( σt ). This value is obtained by subtracting 1.0 from the density and multiplying the remainder by 1,000. The σt has no units and is an abbreviated density of seawater controlled by salinity and temperature only. ird fine

WebFor water of low salinity such as the Baltic Sea, however, there are greater discrepancies caused chiefly by variation of ionic relationships. No detailed investigations have been … WebSince the range of densities in the ocean is rather small, often the density value is shortened and is expressed as sigma-t or σ t. Sigma-t is calculated as: (density – 1) x 1000. So it essentially just looks at the last three decimal places of the density value. Thus a density of 1.0275 g/cm 3 would have a σ t of 27.5. ird first return
