This data release presents the concentration of zinc, oxygen, pH, temperature, and the time point at which measurements were taken for experimental oxidation work regarding zinc and copper sulfide minerals. These data accompany the following publication: Gartman, A., Whisman, S.P., and Hein, J.R., 2020, Interactive oxidation of sphalerite and covellite in seawater: implications for seafloor massive sulfide deposits and mine waste: ACS Earth and Space Chemistry, https://doi.org/10.1021/acsearthspacechem.0c00177, where they are also presented as Supplemental Table 1.

Ferromanganese crust samples were collected via dredge during four oceanographic research cruises to the western equatorial Pacific Ocean. The location (latitude, longitude, depth) and concentrations of 27 major and trace elements in the most recent growth layers of ferromanganese crusts from 57 dredge sites are presented here, as well as select seawater chemistry at each location. These data were used in statistical analyses to determine how oceanographic conditions affect the chemical composition of ferromanganese crusts throughout the region. The changes in ferromanganese crust composition show that modern measurements of these primary oceanographic parameters, as well as paleoceanographic reconstructions, can...
