A sample of hydrothermally mineralized foraminifera ooze (D28A) was collected via dredge from a seamount within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for three layer-fractions of the hydrothermal sample are provided here. Measurements were made after heating to 115 C for 48 hours to test the stability of the phyllomanganate...

This portion of the data release presents X-ray diffractograms of sediment subsamples from push cores collected from Loki's Castle and Favne vent fields, on the Mohns Ridge, in the Norwegian Sea. These data were collected in 2018 and 2019 (USGS Field Activity 2018-691-DD and 2019-624-FA). Location information for the sample is included in each Attribute Definition of this metadata file, as well as in the geochemical data table (LokisMohns_marine_mineral_geochemistry.csv) of this multi-table data release.

This data release compiles element composition data for more than 600 deep-ocean mineral samples from more than 25 research cruises in the Pacific Ocean since 1979 that involved USGS researchers. Deep-ocean mineral sample types encompassed in this data release include ferromanganese crusts, manganese nodules, phosphorites, and hydrothermal minerals. This data release is comprised of both unpublished as well as previously published data and reports and includes analytical methods and instrument detection limits whenever available.

This data release contains geochemical data of sediment subsamples collected in 2018 and 2019 from Loki’s Ridge and Favne Vent Fields, Mohns Ridge, part of the Arctic Mid-Atlantic Ridge. Data include major, minor and trace element concentrations, location information (latitude, longitude, depth), analytical methods, and instrument detection limits where available.

Ferromanganese crusts were collected via dredge from seamounts within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and major and trace element geochemical and x-ray diffraction mineralogy analyses. Geochemical and mineralogy data, bulk and layer thickness information, as well as location information (latitude, longitude, depth) for each ferromanganese crust sample are provided here. These...

This data release contains computed tomography (CT) scans, photographs, X-ray fluorescence (XRF) scans, geochemical data, X-ray diffractograms (XRD), and gamma-ray bulk density of push cores and sediment subsamples from those cores collected in 2018 and 2019 from Loki’s and Favne Vent Fields, Mohns Ridge, part of the Arctic Mid-Atlantic Ridge. For the geochemical section of the release, data include major, minor and trace element concentrations, location information (latitude, longitude, depth), analytical methods, and instrument detection limits where available.

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...
