Title:
X-ray diffraction data (XRD) for ferromanganese crusts, nodules, coated cobbles, and sediments from seamounts in the Papahanaumokuakea Marine National Monument
Abstract:
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.
Supplemental_Information:
We acknowledge funding from the USGS Coastal and Marine Hazards and Resources program through the USGS Pacific Coastal and Marine Science Center. This work was funded in part by the U.S. Department of the Interior, Bureau of Ocean Energy Management through Interagency Agreement M22PG00026 with the USGS. Sample collection was enabled by a grant from NOAA Ocean Exploration (NA21OAR0110199) to Beth Orcutt and supported by operational funds to the Ocean Exploration Trust by NOAA funding of the Ocean Exploration Cooperative Institute (NA19OAR4320072). The research within the Papahanaumokuakea Marine National Monument was permitted by the US Fish and Wildlife Service of the Department of the Interior (PMNM-2021-021) in consultation with the Office of Hawaiian Affairs and the Papahanaumokuakea Native Hawaiian Cultural Working Group.

  7. How does the data set describe geographic features?
    Hawaii_Seamounts_marine_minerals_XRD_data.csv
    Comma-delimited file containing results from x-ray diffraction analyses of ferromanganese crusts. Position indicates the two-theta angle at which the x-ray diffractometer measured the X-ray diffraction of the powdered sample and counts indicate intensity which is the measurement of the number of X-rays detected at a specific angle. Location information for the samples areis included in each Attribute Definition of this metadata file and not the data table. The header for each column of diffraction data is a sample name. Unique sample names include a cruise ID, a sample number, and may include further dashed numbers and/or letter(s) to denote the sample number/subsample. Some NA134 samples were subsampled shipboard by non-USGS collaborators and are differentiated by "_shipboardsubsample", while other samples with same numbers are sampled by USGS. For NA138 samples, "_bulksediment" indicates bulk push core sediments. For NA138 samples, a number or letter after the sample number indicates a specific subsample. For NA138 samples, "Bulk" and "Bulk-2" indicates analysis done without substrate, and "Bulk-1" indicates with substrate. (Source: Producer defined)

Why was the data set created?

These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the global ocean.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 01-May-2022 (process 1 of 5)
    Samples 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. USGS scientists contributed to sample collection as remote participants from shore. Non-USGS collaborators were responsible for shipboard sample collection and initial sample handling. Subsamples were then sent to PCMSC and analyzed by USGS scientists to generate the data reported here.
    Date: 07-Feb-2023 (process 2 of 5)
    Samples were sent to USGS for further subsampling and major and trace element geochemical analyses.
    Date: 29-Sep-2023 (process 3 of 5)
    At USGS, bulk portions, individual layers, or other parts of sample were sampled using a ceramic knife and then ground using an agate mortar and pestle to approximately 75 micrometers. Data sources produced in this process:
    • samples
    Date: 30-Oct-2024 (process 4 of 5)
    Powdered samples were backloaded and tamped into sample holders and run in a Panalytical XPert3 x-ray diffractometer (XRD; https://www.malvernpanalytical.com/) with CuK-alpha radiation and graphite monochromator. Measurements were taken at intervals of 0.2 degrees 2-theta between 4 degrees and 70 degrees 2-theta at 40 kilovolts and 45 milliamps. Data sources used in this process:
    • samples
    Data sources produced in this process:
    • results
    Date: 14-Nov-2024 (process 5 of 5)
    Results from the diffraction analyses were combined into a comma-delimited text values document (Hawaii_Seamounts_marine_minerals_XRD_data.csv). Data sources used in this process:
    • results
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    X-ray diffraction data were tested for accuracy by intermittently analyzing a powdered quartz reference sample to verify the one hundred intensity peak at 26.6 degree two-theta. When the quartz peak was in the proper position, we infer that other measured peak positions in the sample are accurate. Peak intensities are considered semiquantitative since no quantitative standards were analyzed for this dataset.
  2. How accurate are the geographic locations?
    A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. The horizontal accuracy was determined with the ship's GPS navigation, which is accurate to less than 5 m.
  3. How accurate are the heights or depths?
    Depth information for samples was collected using ship sonar technology. A formal accuracy assessment of the vertical positional information in the dataset has not been conducted.
  4. Where are the gaps in the data? What is missing?
    Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    No formal logical accuracy tests were conducted.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
