Chen, Guanghui; Rapp, Insa; Sieber, Matthias; Achterberg, Eric Pieter; Conway, Tim M; Gledhill, Martha; Hopwood, Mark James; Xie, Ruifang C (submitted): Temporal variability in offshore Fe fluxes in the Peruvian oxygen minimum zone across an El Niño termination.
Dissolved and particulate Fe concentrations and Fe isotopic compositions (δ56Fe) were determined from two shelf-slope transects at 12 degree S and 14 degree S in the Peruvian upwelling zone. Samples were collected during cruises M136, M137 and M138 in April and June 2017 using trace metal-clean GO-FLO bottles (profiles) and a towed-fish sampler (surface samples). Dissolved samples were filtered through 0.2 μm polyethersulfone (PES) filters (profiles) or AcropackTM capsule filters (Pall®; 0.8/0.2 μm; surface samples) into acid-cleaned low-density polyethylene (LDPE) bottles. Particulate samples were collected on the PES filters. These data are used to evaluate the partitioning of Ba isotopes between the dissolved and particulate phases. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.995338"!
