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

Surface (~2 meters) water samples for dissolved trace metal concentrations were collected using a custom trace metal clean "towfish" sampling system (Mellett and Buck 2020) on the R/V Roger Revelle between 18 August and 6 September 2018 (during cruise RR1813). A total of 24 samples were filtered (<0.2 micrometers, Pall Acropak) inline, collected in acid-cleaned 125-milliliter 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 (Hollister et al. 2020). 

Samples were collected at sea by Ph.D. student Travis Mellett (USF) and Dr. Salvatore Caprara (USF). Sample analyses for dissolved trace metals were performed by Shannon Burns (USF) with assistance from Dr. Salvatore Caprara (USF).
