Surface transects for arsenic speciation, antimony speciation, and alkaline phosphatase activity from R/V Knorr cruise KN204-01 in the Subtropical North Atlantic Ocean in 2011 (U.S. GEOTRACES NAT project)

<p>Surface transects for arsenic speciation, antimony speciation, and alkaline phosphatase activity</p>

<p>Data for the concentrations of the dissolved (&lt;0.4 µm) arsenic species: total inorganic As (III+V), arsenite (AsIII), As(V), monomethyl As, dimethyl As,&nbsp; and the activity of the enzyme alkaline phosphatase (unfiltered).</p>

<p>Please note that some US GEOTRACES data may not be final, pending intercalibration results and further analysis.
