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: 06-Feb-2020 (process 1 of 4)
    Samples are rocks and were collected by the ROV's manipulator arm. Once recovered shipboard photographed and returned to shore. Amy Gartman attended 2020-602-FA, cruise name AT42-22.
    Date: 01-Aug-2020 (process 2 of 4)
    At USGS, bulk samples and subsamples were collected from relevant regions of the rocks. Data sources produced in this process:
    • samples
    Date: 01-Sep-2020 (process 3 of 4)
    Subsamples were powdered using a shatterbox and powders were mailed to SGS Laboratories, Lakefield, Ontario, Canada. Data sources used in this process:

This reference contains the original map and location names included in this dataset.

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

  1. How well have the observations been checked?
    All geochemistry data were calibrated against certified reference materials. The instruments and techniques used to generate the geochemical data are included in the data table. Limits for each analyte's detection by an instrument are reported in the table. The value -8888 indicates that the measurement for an analyte was below the detection limit. The value -7777 indicates that the value was above the technique limit. Values of -9999 for concentration attributes indicate that no analysis was performed. Values of NaN and -9999 for method and detection limit attributes respectively indicate that no information was available. For this dataset, the Certified Reference Material used include OREAS753, 680, 13b, all by Ore Research and Exploration Pty Ltd, and Mount Pleasant (MP)-2a, by Natural Resources Canada. Accuracy is better than 5 percent for all elements except for As, V, and Hg, for which accuracy was better than 10 percent, and Te, which was 10.7 percent.
  2. How accurate are the geographic locations?
    The horizontal accuracy for each sample was obtained from the ROV's Ultra Short Baseline Positioning System (USBL) navigation after calibration to the CASIUS (Calibration of Attitude Sensors In USBL Systems) calibration system. Accuracy for this depth is approximately 10- 20 m.
  3. How accurate are the heights or depths?
    The vertical accuracy was determined using multiple DVLs (Doppler Velocity Loggers) on the ROV, which are accurate to less than 1 m.
  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?
