Trace metal data from water samples during METEOR cruise M121

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
