gsw_O2sol_SP_pt

solubility of O2 in seawater

Contents

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)
O2sol =
