Online_Linkage: https://doi.org/10.5066/P1DJPX9G Description: Abstract: This data release contains geochemical data of oxidized subsamples of rock samples collected from the Escanaba Trough 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 geochemical analyses. Data include major, minor, and trace element concentrations, location information (latitude, longitude, depth), analytical methods, and instrument detection limits where available. Purpose: These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the global ocean.

The average RPD between duplicate measurements was 10-20 percent for Y, Er, Pr, Eu, K, W, Tb, Tl, Rb, and In. Higher RPDs (>20 percent) were observed for Au, Ir, Pd, Pt, Rh, Ru, Gd, Dy, Te, Ca, Cs, Ni, Yb, Sm, Nd, and Nb.

The instruments and techniques used to generate the geochemical data are included in the data table and also summarized below in the Source Citations since data were generated by commercial laboratories. 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 and the value -7777 indicates that the measurement for an analyte was above the detection limit. Values of -9999 indicate that no analysis was performed. 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. Many samples do not have chemistry data because analyses were performed on representative samples only. 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 m. 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: Source_Information: Source_Citation: Citation_Information: Originator: Activation Laboratories Ltd.

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 freeze dried, then the weathered or depositional outer later of the rock was carefully scraped off using a ceramic blade. This outer layer was 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. Powdered samples (10-50 grams) were then mailed to commercial analytical labs, Actlabs and Intertek, in individual plastic screw-top containers for geochemical analyses. See Source Citations for information on geochemical techniques. Source_Used_Citation_Abbreviation: geochemistry Source_Used_Citation_Abbreviation: PGE data Process_Date: 20230824 Process_Step: Process_Description: Total rare earth elements plus yttrium (Total_REY) were calculated by summing the concentration of rare earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Y in each sample. Percentage of the heavy rare earth elements was calculated by taking the sum of heavy rare earth elements (Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) and Y and dividing the sum by the Total_REY value for each sample.
