©2020 Biological and Chemical Oceanography Data Management Office.Dissolved lead (Pb), the Pb passing through a 0.2µm Acropak capsule filter, is reported in picomoles Pb per kg of seawater. (The sample size was quantified volumetrically at room temperature, then converted to weight units assuming a density of 1.027 g/cc.) Samples were collected on the U.S. GEOTRACES North Atlantic Zonal Transect, Legs 1 and 2, in 2010 and 2011.
Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis.
