Online_Linkage: https://doi.org/10.5066/P13VZZEY Description: Abstract: Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and analyzed for mineralogy by x-ray diffraction. Powder x-ray diffraction data for the hydrothermal samples are provided here. Location information (longitude, latitude, and depth) for each sample is included in each Attribute Definition of this metadata file as well is in the co-released geochemistry data table. We acknowledge the National Science Foundation for funding cruise KM0506 during which these rocks were collected (Grant OCE-0351437). Purpose: These data serve to expand the knowledge and statistics for deep ocean seabed mineral occurrences and their composition throughout the global ocean.

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. Logical_Consistency_Report: No formal logical accuracy tests were conducted. Completeness_Report: 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The singular value for water depth for each sample was calculated from shipboard dredge log records to account for ship-based depth soundings, the length of dredge wire out, movement by the ship, approximate seamount slope, and multiple bites of the dredge along each dredge track in order to maximize location accuracy. A formal accuracy assessment of the vertical positional information in the dataset has not been conducted. Lineage: Process_Step: Process_Description: Rock samples were collected via dredge on R/V Kilo Moana from Samoa hotspot region and shipped to USGS scientists by mail after returning to shore. Process_Date: 20050405 Process_Step: Process_Description: At the USGS Pacific Coastal and Marine Science Center Marine Minerals Lab, bulk portions, individual layers, or other parts of rock samples were subsampled using a ceramic knife and then ground using an agate mortar and pestle to approximately 75 micrometer fineness. Process_Date: 20060201 Process_Step: Process_Description: Powdered samples were backloaded and tamped into sample holders and run in a Panalytical X Pert3 x-ray diffractometer (XRD; https://www.malvernpanalytical.com/) with CuK-alpha radiation and graphite monochromator. Measurements were taken with a step size of 0.02 degrees two-theta between 5 degrees and 70 degrees two-theta and power of 40 kilovolts and 45 milliamps.
