<Summary>Trace metal clean sampling equipment was deployed on a series of cruises along the Peruvian Oxygen Minimum Zone to facilitate the observation of contamination prone chemical parameters. All trace metal sample collection, handling, and analysis was conducted in accordance with GEOTRACES protocols which have been updated through the SFB754 program (Cutter et al., 2014). The deployment of an over-pressured clean container on deck facilitated sampling and collection of trace metal and other contamination-prone samples at sea. 24 Ocean Test Equipment (OTE) samplers were deployed mounted on a powder coated sampling CTD (Sea-Bird SBE25) rosette using a Kevlar conducting cable with sample handling and preservation as per Rapp et al., (2019). Samples were acidified, pre-concentrated and analyzed exactly as per Rapp et al., (2017). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.974053"!</Summary>
