gsw_Hesol_SP_pt

Contents

USAGE:

Hesol = gsw_Hesol_SP_pt(SP,pt)

DESCRIPTION:

Calculates the helium 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
as listed in  Weiss (1971). 

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:

Hesol = solubility of helium                                  [ 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;]

Hesol = gsw_Hesol_SP_pt(SP,pt)
