  1. Equation of State (EOS-80) A through N are polynomials T is temperature in oC S salinity P pressure in bars Determines water density from T, S, and P

  2. Check values:

  3. 90 % of Ocean Water Mean T & S for World Ocean Greater influence of salinity on density

  4. Effects of Temperature and Salinity on Density x 10-4 oC-1 x 10-4 S-1 Saline Contraction Thermal Expansion Density changes by 0.2 kg/m3 for a T change of 1oC, and by 0.8 kg/m3 for a S change of 1.
