Seawater Preformed Salinity (GSW Formulation)

Description

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.
