Practical Salinity, S_P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). The practical salinity at the sea floor is that adjacent to the ocean bottom, which would be the deepest grid cell in an ocean model. This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity_at_sea_floor.
