Dataset: Dissolved trace metal (Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb) concentrations from depth profile samples collected on the 2018 EXPORTS cruise (RR1813) to the subarctic North Pacific near Ocean Station PAPA (Station P) on R/V Roger Revelle

Samples for dissolved trace metal concentrations were collected using a trace metal clean (TMC) rosette (Measures et al. 2008) on the R/V Roger Revelle on 8 September 2018 (R2R event #RR1813-SE-20180908.1732.001). A total of 10 depths were sampled for dissolved (<0.2 micrometers (μm), Pall Acropak) trace metals, between 95 meters (m) to 825 m. All depths were sampled in triplicate for intercalibration; only the results from the Buck lab are reported here. Samples were collected in acid-cleaned 125-milliliter (mL) low-density polyethylene (LDPE, Nalgene) bottles, and acidified to 0.024 M hydrochloric acid (HCl, Fisher Optima). Dissolved trace metal (Fe, Cu, Mn, Co, Ni, Cu, Zn, Cd, Pb) concentrations were determined by high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS) at the University of South Florida (Burns et al. 2023).

Sample analyses for dissolved trace metals were performed by Shannon Burns (USF).
