This subroutine computes the in situ specific volume of sea water (specvol in [m3 kg-1]) from absolute salinity (S [g kg-1]), conservative temperature (T [degC]) and pressure [Pa], using the TEOS10 equation of state. If spv_ref is present, specvol is an anomaly from spv_ref.

Parameters

[in]	t	Conservative temperature relative to the surface [degC].
[in]	s	salinity [g kg-1].
[in]	pressure	pressure [Pa].
[out]	specvol	in situ specific volume [m3 kg-1].
[in]	start	the starting point in the arrays.
[in]	npts	the number of values to calculate.
[in]	spv_ref	A reference specific volume [m3 kg-1].
