USAGE:
O2sol = gsw_O2sol_SP_pt(SP,pt)
DESCRIPTION:
Calculates the oxygen, O2, concentration expected at equilibrium with
air at an Absolute Pressure of 101325 Pa (sea pressure of 0 dbar)
including saturated water vapor. This function uses the solubility coefficients
derived from the data of Benson and Krause (1984), as fitted by Garcia
and Gordon (1992, 1993).
INPUT:
SP = Practical Salinity (PSS-78) [ unitless ]
pt = potential temperature [ deg C ]
with reference sea pressure (pr) = 0 dbar.
SP & pt need to have the same dimensions.
OUTPUT:
O2sol = solubility of oxygen [ umol/kg ]
EXAMPLE:
SP = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
pt = [28.8099; 28.4392; 22.7862; 10.2262; 6.8272; 4.3236;]
O2sol = gsw_O2sol_SP_pt(SP,pt)
