Function beta 

pub fn beta(sa: f64, ct: f64, p: f64) -> Result<f64>

Saline contraction coefficient at constant Conservative Temperature (75-term polynomial approximation)

Arguments

• sa: Absolute Salinity [ g kg-1 ]
• ct: Conservative Temperature (ITS-90) [ deg C ]
• p: sea pressure [ dbar ] (i.e. absolute pressure - 10.1325 dbar)

Returns

Saline (i.e. haline) contraction [ kg/g ] coefficient at constant Conservative Temperature
