"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. " - How do oceanographers measure density
