gsw_kappa_const_t
isothermal compressibility
Contents
USAGE:
kappa_const_t = gsw_kappa_const_t(SA,t,p)
DESCRIPTION:
Calculates isothermal compressibility of seawater.
Note. This is the compressibility of seawater AT CONSTANT IN-SITU
TEMPERATURE
INPUT:
SA = Absolute Salinity [ g/kg ]
t = in-situ temperature (ITS-90) [ deg C ]
p = sea pressure [ dbar ]
( ie. absolute pressure - 10.1325 dbar )
SA & t need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.
OUTPUT:
kappa_const_t = Isothermal compressibility [ 1/Pa ]
Note. The output units are 1/Pa not 1/dbar.
EXAMPLE:
SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
t = [28.7856; 28.4329; 22.8103; 10.2600; 6.8863; 4.4036;]
p = [ 10; 50; 125; 250; 600; 1000;]
kappa_const_t = gsw_kappa_const_t(SA,t,p)
