Abstract:
The file contains dissolved race metal concentrations (Fe, Co, Mn, Ni, Cd, Cu, Pb and Zn), Fe(II), and macronutrients (phosphate, nitrate + nitrite and silicic acid) concentrations of surface water samples (from Tow-Fish system) and station depth profiles (from Titanium CTD rosette). Trace metal concentrations were measured by ICP-MS after preconcentration (Rapp et al. 2017, Anal. Chim. Acta). Fe(II) were analyzed on-board using chemiluminescence flow injection analysis (Hopwood et al. 2017, Sci. Rep.). Number of data flag is following GEOTRACES Quality Flag Policy

Comment:
Seven Fe(II) concentrations were beyond the highest standard addition (20 nM) of calibration curve and are therefore reported as >20 nM.
