swConservativeTemperature {oce} | R Documentation |
Compute seawater Conservative Temperature, according to the GSW/TEOS-10 formulation.
swConservativeTemperature(salinity, temperature = NULL, pressure = NULL, longitude = NULL, latitude = NULL)
salinity |
either practical salinity (in which case |
temperature |
in-situ temperature [degC], defined
on the ITS-90 scale; see “Temperature units” in the documentation for
|
pressure |
pressure [dbar] |
longitude |
longitude of observation. |
latitude |
latitude of observation. |
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.
Conservative temperature in degrees Celcius.

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"]]
.
