Compute seawater Conservative Temperature, according to the GSW/TEOS-10 formulation.
swConservativeTemperature(salinity, temperature = NULL,
pressure = NULL, longitude = NULL, latitude = NULL)either practical salinity (in which case temperature
and pressure must be provided) or an oce object (in
which case salinity, etc. are inferred from the object).
in-situ temperature [\(^\circ\)C], defined
on the ITS-90 scale; see “Temperature units” in the documentation for
swRho.
pressure [dbar]
longitude of observation.
latitude of observation.
Conservative temperature in degrees Celcius.
If the first argument is an oce object, then values for salinity,
etc., are extracted from it, and used for the calculation, and the
corresponding arguments to the present function are ignored.
The conservative temperature is calculated using the TEOS-10 function
gsw_CT_from_t from the gsw package.

The related TEOS-10 quantity ``absolute salinity'' may be computed
with swAbsoluteSalinity. For a ctd object, conservative
temperature may also be recovered by indexing as e.g.
ctd[["conservativeTemperature"]] or ctd[["CT"]].
