2. How were the data generated, processed, and modified?

   Date: 06-Sep-2022 (process 1 of 1)

   Results from lab analyses, detection limits, analytical method information, sample type, cruise identification, and location data were combined into a comma-delimited text values document (MarineMineralGeochemicalData_Part1.csv). URL link for published geochemical data or cruise reports were provided for each sample. Water normalized concentrations were calculated, when necessary, using the following formula: water normalized = [raw element concentration]/[(100 - wt.% water)/100]. Data sources used in this process:

   • All source contributions were used for this dataset

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?
   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 and the value -7777 indicates that the measurement for an analyte was above the detection limit. Values of -9999 for concentration attributes indicate that no analysis was performed. Values of -9999 for method and detection limit attributes indicate that no information was available.
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. Depth values were taken from cruise reports and publications (reference links provided). Average depth is reported for samples collected with a dredge. 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. 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.
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?
