Title:
Major and trace element geochemistry data for hydrothermal manganese oxide rocks from the Samoa hotspot region in the South Pacific Ocean collected during research expedition KM0506
Abstract:
Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and sent to SGS laboratories, Canada for major and trace element geochemistry. Major and trace element concentrations and thickness for the hydrothermal manganese oxides as well as location information (latitude, longitude, depth) for samples are provided here. This data release is comprised of legacy samples that have not been previously published. We acknowledge the National Science Foundation for funding cruise KM0506 during which these rocks were collected (Grant OCE-0351437).

Why was the data set created?

These data serve to expand the knowledge and statistics for deep ocean seabed mineral occurrences and their composition throughout the global ocean.

How was the data set created?

  1. From what previous works were the data drawn?
    geochemistry (source 1 of 1)
    SGS Minerals Laboratory, Mississauga, Ontario, Canada, 2006, Geochemical Element Analysis.

    Online Links:

    Type_of_Source_Media: geochemical analyses
    Source_Contribution:
    Fe, Mn, Si, Al, Ca, Mg, K, Na, P, Mo, and Ti were determined by X-Ray Fluorescence (XRF) on borate fused disks; S, Ba, Cr, Cu, Li, Sr, and Zn were determined by four acid digestion combined ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy); Ag, As, Be, Bi, Cd, Co, Cs, Ge, Hf, In, Nb, Ni, Pb, Rb, Sb, Sc, Sn, Ta, Th, Tl, U, V, W, and Zr were determined by four acid digestion combined ICP-MS (Inductively Coupled Plasma Mass Spectrometry); H2OM percent moisture was determined by gravimetric analysis; Cl was determined by ion selective electrode; Hg was determined by Cold-Vapour Atomic Absorption Spectrometry. Se and Te were determined by Hydride generation followed by atomic absorption spectroscopy (AAS); Rare Earth Elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) were determined by lithium metaborate fusion followed by ICP-MS.
  2. How were the data generated, processed, and modified?
    Date: 05-Apr-2005 (process 1 of 3)
    Rock samples were collected via dredge on R/V Kilo Moana from Samoa hotspot region and shipped to USGS scientists by mail after returning to shore.
    Date: 01-Feb-2006 (process 2 of 3)
    At the USGS Pacific Coastal and Marine Science Center Marine Minerals Lab, bulk portions, individual layers, or other parts of rock sample were subsampled using a ceramic knife and then ground using an agate mortar and pestle to approximately 75 micrometer fineness. Powdered samples were then sent by USGS to commercial analytical labs, SGS Mineral Laboratory. See Source Citations for information on geochemical techniques.
    Date: 15-Feb-2025 (process 3 of 3)
    Results from the SGS Mineral Laboratory analyses, detection limits, analytical method information, location data, and sample information were combined into a comma-delimited text values document. Data sources used in this process:
    • geochemistry
  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 by SGS Minerals Laboratory as part of their standard protocols. 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. Reproducibility as percent difference is better than 5 percent for most elements except Pr, Sm, Se, Hf, Pb, Ta, Te, Eu, 5 to 9 percent, Ba, Dy, Sn, 11 to 13 percent, Ho, Sc, U, Ag, 17 to 22 percent, Tm 25 percent, and Er 29 percent. Values of -9999 for concentration attributes indicate that no analysis was performed. Values of Nan for Sample Depth interval attributes indicate that this measurement is not applicable for the given sample.
  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?
    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.
  4. Where are the gaps in the data? What is missing?
    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.
  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?
