gsw_O2sol_SP_pt

`solubility of O2 in seawater`

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).```
```Note that this algorithm has not been approved by IOC and is not work
from SCOR/IAPSO Working Group 127. It is included in the GSW
Oceanographic Toolbox as it seems to be oceanographic best practice.```

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 = `
`   1.0e+002 *`
