Dissolved Ga and Ba from surface tows from R/V Knorr cruises KN199-04, KN199-05, and KN204-01 in the Subtropical northern Atlantic Ocean from 2010-2011 (U.S. GEOTRACES NAT project)

<p>Lab-based measurements of dissolved Gallium (Ga)&nbsp;and Barium (Ba)&nbsp;from surface tows from the 2010 and 2011 US GEOTRACES cruises (GT10 and GT11).</p> <p><strong>STATUS NOTE:</strong>&nbsp;These data were significantly updated on 30 August 2016. A volume correction had not been applied to the previous version, and thus all of the original values&nbsp;needed to be multiplied by 0.9805. This correction has been applied in the 30 August version, now available online. There were also some samples that were&nbsp;re-analyzed for Ba with the values revised accordingly. Additionally, the PIs&nbsp;withdrew the Pb data (in the original version) because higher quality&nbsp;Pb data are already available&nbsp;from these&nbsp;cruises.</p> <p>Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis.
