gsw_temps_maxdensity
temperatures of maximum density of seawater
Contents
USAGE:
[t_maxden, pt_maxden, CT_maxden] = gsw_temps_maxdensity(SA,p)
DESCRIPTION:
Calculates the temperatures of maximum density of seawater. This
function returns the in-situ, potential, and Conservative temperatures
at which the density of seawater is a maximum, at given Absolute
Salinity, SA, and sea pressure, p (in dbar).
INPUT:
SA = Absolute Salinity [ g/kg ]
p = sea pressure [ dbar ]
(ie. absolute pressure - 10.1325 dbar)
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA is MxN.
OUTPUT:
t_maxden = In-situ temperature at which the density of seawater
is a maximum for given Absolute Salinity and pressure,
measured on the ITS-90 temperature scale. [ deg C ]
pt_maxden = potential temperature at which the density of seawater
is a maximum for given Absolute Salinity and pressure.
This is the potential temperature referenced to a sea
pressure of 0 dbar. [ deg C ]
CT_maxden = Conservative Temperature at which the density of
seawater is a maximum for given Absolute Salinity
and pressure. [ deg C ]
EXAMPLE:
SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p = [ 10; 50; 125; 250; 600; 1000;]
[t_maxden, pt_maxden, CT_maxden] = gsw_temps_maxdensity(SA,p)
