Salinity data from eWOCE Atlas

Pacific = Cruise 18DD9403/1, Station W043

Atlantic = Cruise 32OC202/1, Station 50

Lithium was estimated from the formula 1323*Salinity/1.80655/(1000-1.81578*Salinity/1.80655)

where 1.80655 is the Salinity/Chlorinity ratio and 1323 is the number of µmoles of Li/Chlorinity -
