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. Web7. Can oceanographers measure the horizontal pressure gradients that matter for large-scale ocean flow? NO. Why not, meteorologists use barometers? Meteorologists can do it because air is so light that it doesn't matter if one barometer is on the floor and the adjacent one is slightly higher or lower. did frank sinatra fight in ww2WebMar 28, 2024 · Oceanographers do measure the density of ocean water by actually taking a sample of sea water out of the ocean and then taking it to the laboratory to be measured. … did frank sinatra have any grandchildren
