Description:
Abstract:
Ferromanganese crusts were collected via dredge from seamounts within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for bulk and layer fractions of the ferromanganese crusts are provided here. Location information for the sample is included in each Attribute Definition of this metadata file, as well as in the geochemical data table (Tuvalu_RR1310_FeMn_geochem_data.csv) of this multi-table data release.
Purpose:
These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the global ocean.
Supplemental_Information:
Samples analyzed for this data release were collected on a cruise funded by National Science Foundation grant #1154070. All metadata associated with cruise RR1310 is available upon request from the Oregon State University Marine and Geology Repository (http://osu-mgr.org).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
X-ray diffraction data were tested for accuracy by intermittently analyzing a powdered quartz reference sample to verify the one hundred intensity peak at 26.6 degree two-theta. 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.

Process_Step:
Process_Description:
USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and mineralogical analyses.
Process_Date: 20160926
Process_Step:
Process_Description:
At USGS, bulk portions or individual layers were sampled from the ferromanganese crusts using a ceramic knife and then ground using an agate mortar and pestle to approximately 75 micrometers.
Process_Date: 20170501
Process_Step:
Process_Description:
Powdered samples were backloaded and tamped into sample holders and run in a Panalytical XÕPert3 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.

Entity_Type:
Entity_Type_Label: Tuvalu_RR1310_FeMn_Primary XRD_RawData.csv
Entity_Type_Definition:
Comma-delimited file containing results from x-ray diffraction analyses of ferromanganese crusts. 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, which follows the scheme of dredge number followed by an underscore and then the sample interval type, B for bulk or L for layer, and finally the numerical millimeter range that the interval spans as counted from the surface of the sample. One sample, D20-54, has nodule instead of the bulk and layer distinction, since it was a nodule sample. The addition of an underscore and two after the primary dredge and sample numbers indicates that more than one rock was given the same Sample ID and that rock two of two was analyzed.
