Salinity data from eWOCE Atlas

Pacific = Cruise 18DD9403/1, Station W043

Atlantic = Cruise 32OC202/1, Station 50

Chloride was estimated from the formula 28176.5*Salinity/1.80655/(1000-1.81578*Salinity/1.80655)

where 1.80655 is the Salinity/Chlorinity ratio and 28176.5 is the number of mmoles of Chlorinity -
