Abstract:
The file contains dissolved and total dissolvable trace metal concentrations (Fe, Co, Mn, Ni, Cd, Cu, Pb, Zn and V), hydrogen peroxide (H2O2), Fe(II), and iodide and iodate concentrations of surface water samples and station depth profiles. Trace metal concentrations were measured by ICP-MS after preconcentration (Rapp et al. 2017, Anal. Chim. Acta). Fe(II) and H2O2 were analyzed on-board using chemiluminescence flow injection analysis (Hopwood et al. 2017, Sci. Rep.). Iodide concentrations were analyzed by cathodic stripping square wave voltammetry (Luther et al. 1988, Anal. Chem.) and Iodate concentrations were measured spectrophotometrically (Chapman and Liss 1977, Mar. Chem.).
