Title:

Geochemical composition of ferromanganese crusts, nodules, and coated cobbles from seamounts in the Papahanaumokuakea Marine National Monument

Abstract:

This portion of the data release provides geochemical analyses data of ferromanganese rock samples collected off the coast of Hawaii. Ferromanganese crusts, nodules, and coated cobbles were collected via ROV from seamounts within the Papahanaumokuakea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. Ferromanganese rock samples were sent to USGS for subsampling and major and trace element geochemical analyses. Major and trace element data as well as location information (latitude, longitude, depth) for each sample are provided here.

Supplemental_Information:

We acknowledge funding from the USGS Coastal and Marine Hazards and Resources program through the USGS Pacific Coastal and Marine Science Center. This work was funded in part by the U.S. Department of the Interior, Bureau of Ocean Energy Management through Interagency Agreement M22PG00026 with the USGS. Sample collection was enabled by a grant from NOAA Ocean Exploration (NA21OAR0110199) to Beth Orcutt and supported by operational funds to the Ocean Exploration Trust by NOAA funding of the Ocean Exploration Cooperative Institute (NA19OAR4320072). The research within the Papahanaumokuakea Marine National Monument was permitted by the US Fish and Wildlife Service of the Department of the Interior (PMNM-2021-021) in consultation with the Office of Hawaiian Affairs and the Papahanaumokuakea Native Hawaiian Cultural Working Group.

Description of sample material (Source: Producer defined)

Value	Definition
bulk nodule	this is a bulk spherical nodule sample.
bulk crust	this is a bulk crust sample.
bulk coated cobble	this is a bulk sample of rounded cobble of rock that is broken from outcrop and changes position and orientation on the seafloor over time allowing ferromanganese crust to accrete on all or most of the surface of the substrate; crust layers may be non-uniform in thickness and/or sublayer orientation due to irregular growth, which differentiates coated cobbles from nodules.
crust layer	this is a layer of a crust sample.
nodule layer	this is a layer of a nodule sample.

How were the data generated, processed, and modified?
Date: 01-May-2022 (process 1 of 8)
Samples were collected via ROV from seamounts off the coast of Hawaii and within the Papahanaumokuakea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. USGS scientists contributed to sample collection as remote participants from shore. Non-USGS collaborators were responsible for shipboard sample collection and initial sample handling. Subsamples were then sent to PCMSC and analyzed by USGS scientists to generate the data reported here.
Date: 07-Feb-2023 (process 2 of 8)
Samples were sent to USGS for further subsampling and major and trace element geochemical analyses.
Date: 29-Sep-2023 (process 3 of 8)
At USGS, bulk portions, individual layers, or other parts of sample were sampled using a ceramic knife and then ground using an agate mortar and pestle to approximately 75 micrometers. Powdered samples were then sent by USGS to commercial analytical labs, Activation Laboratories Ltd. (Actlabs) and Intertek. See Source Citations for information on geochemical techniques.
Date: 07-Apr-2023 (process 4 of 8)
Four samples sent to Actlabs in duplicate: NA138-040-C-Bulk, NA138-054-1-Bulk, NA138-136-Bulk, and NA138-139-Bulk. Averaged concentrations of those duplicate samples are reported here. Duplicate Re concentrations for samples NA138-040-C-Bulk and NA138-054-1-Bulk included one value as below detection limit, so Re concentrations reported for these two samples is the value that was within the detection limit.

At USGS the water content (H2OM) of each sample was determined by gravimetric analysis (approximately 2 grams of material heated in a 105 degree Celsius oven for 2 hours and cooled in a desiccator prior to weighing). Weight percent water (H2OM values) calculated by USGS for all samples are reported here.
Date: 08-Aug-2024 (process 6 of 8)
For samples from cruise ID NA134, USGS H2OM values were used to correct element concentrations in each sample to sorbed-water-free values using the following formula: water normalized = [raw element concentration]/[(100 - wt. percent water)/100]. For samples from cruise ID NA138, Actlabs H2OM values were used to correct element concentrations due to different sample handling. USGS values are still reported here as they more accurately represent total sorbed water. NA138-033-Bulk and NA138-091-B-Bulk did not have USGS H2OM values due to limited sample, for these samples an average of NA138 USGS H2O- values was used. NA138-033-Bulk has no reported Actlabs H20M value, averaged Actlabs H2OM values were used to generate normalized concentrations for NA138-033-Bulk.

Water normalized results from the lab analyses, detection limits, analytical method information, location data, and sample information were combined into a comma-delimited text values document (Hawaii_Seamounts_marine_minerals_geochemistry_data.csv). Data sources used in this process:

This metadata file was edited to reflect that the overall data release was revised to include multiple datasets. No data were changed. (mau@usgs.gov)
What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

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 detection limit attributes indicate that no information was available. Values of NaN for method attributes indicate that no information was available in columns containing text.
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.
How accurate are the heights or depths?
Depth information for samples was collected using ship sonar technology. A formal accuracy assessment of the vertical positional information in the dataset has not been conducted.
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.
How consistent are the relationships among the observations, including topology?
No formal logical accuracy tests were conducted.
