For a given thermodynamic state, calculate the derivatives of specific volume with conservative temperature and absolute salinity, using the TEOS10 expressions.

Parameters:

t	Conservative temperature [degC].
s	Absolute salinity [g kg-1].
pressure	pressure [Pa].
dsv_dt	The partial derivative of specific volume with conservative temperature [m3 kg-1 degC-1].
dsv_ds	The partial derivative of specific volume with absolute salinity [m3 kg-1 (g/kg)-1].
start	The starting point in the arrays.
npts	The number of values to calculate.

subroutine, public calculate_compress_teos10(
    T T,
    S S,
    pressure pressure,
    rho rho,
    drho_dp drho_dp,
    start start,
    npts npts
    )

This subroutine computes the in situ density of sea water (rho in [kg m-3]) and the compressibility (drho/dp = C_sound^-2) (drho_dp [s2 m-2]) from absolute salinity (sal in g/kg), conservative temperature (T [degC]), and pressure [Pa]. It uses the subroutines from TEOS10 website.

Parameters:

t	Conservative temperature [degC].
s	Absolute salinity [g kg-1].
pressure	Pressure [Pa].
rho	In situ density [kg m-3].
drho_dp	The partial derivative of density with pressure (also the inverse of the square of sound speed) [s2 m-2].
start	The starting point in the arrays.
npts	The number of values to calculate.
