gsw_sigma1_CT
potential density anomaly with reference pressure
of 1000 dbar, this being this particular potential
density minus 1000 kg/m^3
Contents
USAGE:
sigma1_CT = gsw_sigma1_CT(SA,CT)
DESCRIPTION:
Calculates potential density anomaly with reference sea pressure of
1000 dbar.
INPUT:
SA = Absolute Salinity [ g/kg ]
CT = Conservative Temperature [ deg C ]
SA & CT need to have the same dimensions.
OUTPUT:
sigma1_CT = potential density anomaly with [ kg/m^3 ]
respect to a reference pressure of 1000 dbar,
that is, this potential density - 1000 kg/m^3.
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;]
sigma1_CT = gsw_sigma1_CT(SA,CT)
