Transect sulfur chemistry, SUP05 cell densities, denitrification and carbon fixation rates for the Peruvian oxygen minimum zone sampled in February-March 2013

The data set includes, sulfide and sulfur concentrations, SUP05 cell densities, as well as denitrification and carbon fixation rates (based on 15N- and 13C-labelled in situ incubation experiments). The transect extends from the sulfidic upper shelf into the sulfide-free offshore oxygen minimum zone.
