Online_Linkage: https://doi.org/10.5066/P1DJPX9G Description: Abstract: This data release contains x-ray diffraction data of rock samples collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 (USGS Field Activity 2022-621-FA). Samples were taken to the USGS Pacific Coastal Marine Science Center for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for the rind layer of the rocks are provided in this dataset. Location information (latitude, longitude, depth) for each sample are provided in each Attribute Definition of this metadata file. Purpose: These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the US Exclusive Economic Zone and global ocean. Supplemental_Information: Additional information about the field activities from which these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=2022-621-FA Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

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: Validity of XRD data verified by comparing returned peaks to values based on expected minerology from each sample location and type. 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: The location of rock samples were determined using ROV Jason's ultra-short baseline (USBL) navigation. Accuracy for this depth is approximately 6-26 meters. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Vertical accuracy was determined with ROV Jason's altimeter, which is accurate to less than 1 m. No formal positional accuracy tests were conducted. Lineage: Process_Step: Process_Description: Rock samples were collected on the R/V Thomas G. Thompson between May 24, 2022, and June 13, 2022, during the TN403 Escanaba Trough expedition, which was led and staffed by USGS employees. Rocks were collected from the seafloor using the ROV Jason's manipulator arm at water depths between 3192 and 3319 meters. Rock samples were frozen immediately upon recovery from the ROV, stored frozen, and shipped on ice to the USGS Pacific Coastal and Marine Science Center in Santa Cruz, CA. Process_Date: 20220613 Process_Step: Process_Description: In the USGS Pacific Coastal and Marine Science Center Global Seabed Mineral Resources Lab, rock samples were subsampled, freeze dried, then ground to a powder (approximately 75 micrometers) using a shatterbox and ceramic-lined bowls and ceramic pucks. Ceramic-lined bowls and pucks were cleaned thoroughly with quartz powder and detergents between samples to avoid cross-contamination. Process_Date: 20230824 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 at intervals of 0.2 degrees 2-theta between 4 degrees and 70 degrees 2-theta at 40 kilovolts and 45 milliamps. Process_Date: 20230830 Process_Step: Process_Description: Results from the diffraction analyses were combined into a comma-delimited text values document (TN403_Oxidized_XRD.csv).

Location information for the samples are 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. The marine subsamples headers follows the scheme of Dive#-Rock#-rind (for example, J2-1424-R07-rind is ROV Jason dive number J2-1424, rock number 7, rind composition). Deviations from this naming convention include samples ending in _carbon, which indicate a graphitic tar composition, and samples ending in colors such as _orange_black_rind, which indicate the specific color of the oxidized layer that was subsampled.
