X-ray diffraction data (XRD) for ferromanganese crusts, nodules, coated cobbles, and sediments from seamounts in the Papahanaumokuakea Marine National Monument
Powder x-ray diffraction data (XRD) for samples are provided in this portion of the data release. Ferromanganese crusts, nodules, coated cobbles, and push core sediments were collected via ROV from seamounts off the coast of Hawaii and within the Papahanaumokuakea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. Samples were sent to USGS for subsampling and x-ray diffraction analyses. Location information for the samples is included in each Attribute Definition of this metadata file, as well as in the geochemical data table (Hawaii_Seamounts_marine_minerals_geochemistry_data.csv) of this multi-table data release.
