## USAGE:

    Krsol = gsw_Krsol(SA,CT,p,long,lat)

## DESCRIPTION:

    Calculates the krypton, Kr, 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 Weiss and Kyser (1978).

    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:

    SA  =  Absolute Salinity                                        [ g/kg ]
    CT  =  Conservative Temperature                                [ deg C ]
    p   =  sea pressure                                             [ dbar ]
           (i.e. absolute pressure - 10.1325 dbar)
    long  =  longitude in decimal degrees                     [ 0 ... +360 ]
                                                       or  [ -180 ... +180 ]
    lat   =  latitude in decimal degrees north               [ -90 ... +90 ]

    SA & CT need to have the same dimensions. p, lat and long may have
    dimensions 1x1 or Mx1 or 1xN or MxN, where SA and CT are MxN.

## OUTPUT:

    Krsol = solubility of krypton                                [ umol/kg ]

## EXAMPLE:

    SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
    CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
    p =  [     10;      50;     125;     250;     600;    1000;]
    lat =  [      4;       4;       4;       4;       4;       4;]
    long = [    188;     188;     188;     188;     188;     188;]

    Krsol = gsw_Krsol(SA,CT,p,long,lat)

    Krsol =
