TLDR
A new high pressure equation of state for water and seawater has been derived from the experimental results of Millero and coworkers in Miami and Bradshaw and Schleicher in Woods Hole as mentioned in this paper.Abstract:
A new high pressure equation of state for water and seawater has been derived from the experimental results of Millero and coworkers in Miami and Bradshaw and Schleicher in Woods Hole The form of the equation of state is a second degree secant bulk modulus
K = Pv0(v0−vp=K0+AP+BP2
K = Kw0+aS+bS32
A = Aw+cS+dS32
B = Bw+eS
where ν0 and νP are the specific volume at 0 and P applied pressure and S is the salinity (ℵ) The coefficients KWO, AW, and BW for the pure water part of the equation are polynomial functions of temperature The standard error of the pure water equation of state is 43 × 10−6 cm3 g−1 in νWP The temperature dependent parameters a, b, c, d, and e have been determined from the high pressure measurements on seawater The overall standard error of the seawater equation of state is 90 × 10−6 cm3 g−1 in νP Over the oceanic ranges of temperature, pressure, and salinity the standard error is 50 × 10−6 cm3 g−1 in νP This new high pressure equation of state has recently (1979) been recommended by the UNESCO Joint Panel on Oceanographic Tables and Standards for use by the oceanographic communityread more

The composition of Standard Seawater and the definition of the Reference-Composition Salinity Scale
TL;DR: Reference Seawater is defined as any seawater that has the Reference Composition and a new Reference-Composition Salinity S R is defined to provide the best available estimate of the Absolute Salinity of both Reference Seawaters and the Standard SeawATER that was used in the measurements of the physical properties as discussed by the authors.

A method for computing horizontal pressure-gradient force in an oceanic model with a nonaligned vertical coordinate
TL;DR: A pressure-gradient algorithm that achieves more accurate hydrostatic balance between the two components and does not lose as much accuracy with nonuniform vertical grids at relatively coarse resolution, and generalized the monotonicity constraint to guarantee nonnegative physical stratification of the reconstructed density profile in the case of compressible equation of state.
