gsw_entropy_from_pt
specific entropy of seawater as a function of
potential temperature
Contents
USAGE:
entropy = gsw_entropy_from_pt(SA,pt)
DESCRIPTION:
Calculates specific entropy of seawater.
INPUT:
SA = Absolute Salinity [ g/kg ]
pt = potential temperature (ITS-90) [ deg C ]
SA & pt need to have the same dimensions.
OUTPUT:
entropy = specific entropy [ J/(kg*K) ]
EXAMPLE:
SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
pt = [28.7832; 28.4210; 22.7850; 10.2305; 6.8292; 4.3245;]
entropy = gsw_entropy_from_pt(SA,pt)
entropy =
400.3895
395.4384
319.8674
146.7905
98.6469
