Seawater Preformed Salinity (GSW Formulation)

Compute seawater Preformed Salinity (S*), according to the GSW/TEOS-10 formulation with gsw::gsw_Sstar_from_SA() in the gsw package.

Usage

swSstar(salinity, pressure = NULL, longitude = NULL, latitude = NULL)

Arguments

salinity: either practical salinity (in which case pressure must be provided) or an oce object with salinity and pressure in its data slot, and with longitude and latitude either there, or in the metadata slot.
pressure: pressure in dbar.
longitude: longitude of observation.
latitude: latitude of observation.

Value

Preformed Salinity, S*, in \(g/kg\).
