Compute the seawater Absolute Salinity, according to the GSW/TEOS-10
formulation with gsw::gsw_SA_from_SP()
in the gsw package.
Typically, this is a fraction of a unit
higher than practical salinity as defined in the UNESCO formulae.
swAbsoluteSalinity(
salinity,
pressure = NULL,
longitude = NULL,
latitude = NULL,
debug = getOption("oceDebug")
)
Absolute Salinity in \(g/kg\).
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).
pressure in dbar.
longitude of observation.
latitude of observation.
an integer specifying whether debugging information is
to be printed during the processing. This is a general parameter that
is used by many oce
functions. Generally, setting debug=0
turns off the printing, while higher values suggest that more information
be printed. If one function calls another, it usually reduces the value of
debug
first, so that a user can often obtain deeper debugging
by specifying higher debug
values.

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