Ferromanganese crusts, nodules, and coated cobbles were collected via ROV from seamounts off the coast of Hawaii and within the Papahānaumokuākea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. Ferromanganese rock samples were sent to USGS for subsampling, major and trace element geochemical analyses, and x-ray diffraction analyses.
