swConservativeTemperature: Seawater conservative temperature, as defined in TEOS-10.

Description

Compute seawater conservative temperature, according to TEOS-10.

Usage

swConservativeTemperature(salinity, temperature, pressure)

Arguments

salinity

either salinity (in which case temperature and pressure must be provided) or a ctd object (in which case salinity, etc. are determined from the object, and must not be

temperature

in-situ temperature [$^\circ$C]

pressure

pressure [dbar]

Value

• Conservative temperature in degrees Celcius.

Details

If the first argument is a ctd object, then values of salinity, etc, are extracted from it, and used for the calculation.

The conservative temperature is calculated using the TEOS-10 function gsw_ct_from_t.

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"]].

Examples

ct <- swConservativeTemperature(35.7, 15, 300)
stopifnot(abs(14.930280459895560 - ct) < 00.000000000000010)
