Title:
Computed tomography (CT) scans of gravity cores and push cores from the Escanaba Trough (Gorda Ridge)
Abstract:
This portion of the data release presents computed tomography (CT) images from gravity core and push core sediment samples collected from the Escanaba Trough vent field, Gorda Ridge, in the northeast Pacific Ocean (USGS Field Activity 2022-621-FA). These data were collected in 2022 and 2023. A Geotek Rotating X-Ray CT (RXCT) system was used to acquire x-ray images and perform CT reconstructions of unsplit core segments. The full three-dimensional data set consists of individual axial slices which are reconstructed images in TIFF format. These axial slices are oriented perpendicular to the long axis of the core. Two-dimensional orthogonal views are also provided that illustrate representative downcore slabs of each core. Geotek software-proprietary XML files are provided in each folder containing axial slices and orthogonal views, containing more image-scaling and information on x-ray system settings and reconstruction parameters.

      The flattening of the ellipsoid used is 1/298.257223563.
  7. How does the data set describe geographic features?
    zip files containing CT images
    The name of each zip file corresponds to the core id. The latitude, longitude, and water depth for each core id can be found in TN403_CoreLocations. Each zip file contains 2 subfolders named 'SliceViews' and 'OrthogonalViews'. The 'SliceViews' folder contains TIFF files of each axial slice and two Geotek software-proprietary metadata files, 'index.xml' and 'WholeCoreRecon.txt'. The 'index.xml' file is generated during reconstruction and contains detailed acquisition and reconstruction metadata. The 'WholeCoreRecon.txt' file summarizes x-ray settings, the source and detector geometry, and core depth information. In the 'OrthogonalViews' folder, 4 TIFF files and their respective Geotek software-proprietary metadata .xml files are included. The 'Orthogonal000' and 'Orthogonal090' components of the TIFF filenames signify two-dimensional downcore views of slabs that are orthogonal to each other. Axial slice TIFFs and orthogonal view TIFFs are 16-bit images with a pixel size of 96 microns, or 104 pixels per centimeter. There are 7 push cores that were scanned as split cores, rather than whole cores (J2-1418-PC08, J2-1418-PC12, J2-1418-PC15, J2-1419-PC05, J2-1419-PC14, J2-1420-PC02, J2-1420-PC14). The zip files for these cores contain an ‘OrthogonalViews’ subfolder with reconstructed TIFF images of the split core, and a ‘SliceViews’ text file with directory information for raw data. The raw data (axial slice TIFF images) for these 7 split core scans can be found in the ‘SliceViews’ subfolder of ‘TN403_SplitCores_CT.zip’. (Source: producer defined)

Why was the data set created?

Images were obtained to characterize sediment in gravity cores and push cores. These data are intended for science researchers, students, policy makers, and the general public.

How was the data set created?

  1. From what previous works were the data drawn?
    TN403_CoreLocations (source 1 of 1)
    Adamczyk, Katlin, Gartman, Amy, Favela, Jaycee, and Tidwell, Jacob, 2025, Location and water depth for gravity cores and push cores from the Escanaba Trough (Gorda Ridge): U.S. Geological Survey, online.

    Latitude, longitude, and water depth information for gravity cores and push cores from this same data release
  2. How were the data generated, processed, and modified?
    Date: 13-Jun-2022 (process 1 of 2)
    Push core and gravity core 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. Push cores were pushed into sediment at 37 locations by ROV Jason’s manipulator arm in water depths between 3201 and 3301 meters. Gravity cores were collected using a gravity corer at 7 locations in water depths between 3209 and 3304 meters. Gravity cores greater than 60 cm in length were cut into sections onboard the ship and labeled ‘X’ (0-60 cm), ‘Y’ (60-120 cm), and ‘Z’ (>120 cm). All cores were stored upright and refrigerated until return to shore.
    Date: 20-Nov-2023 (process 2 of 2)
    CT scans were acquired at the USGS Pacific Coastal and Marine Science Center core facility using a Geotek Rotating X-Ray CT (RXCT) Scanner system, running acquisition software version XCT4. Rotational x-ray images were acquired with a Thermo Kevex PSX10-65W x-ray source every 0.2 degrees at 115 kilovolts (kV) and 450 microamperes. Each whole core segment was scanned individually. Rotational images were reconstructed into axial slice TIFFs using Geotek’s Reconstructor Software. Once reconstructed, the axial slice TIFFs were imported into GeoTek's Image Viewer software and representative two-dimensional orthogonal views were selected. Axial slice TIFF images are organized into a subfolder folder named ‘SliceViews’, and orthogonal TIFF images are in the subfolder ‘OrthogonalViews’. These folders are compressed into single zip files with filenames corresponding to each core scanned. There are 7 push cores that were scanned as split cores, rather than whole cores (J2-1418-PC08, J2-1418-PC12, J2-1418-PC15, J2-1419-PC05, J2-1419-PC14, J2-1420-PC02, J2-1420-PC14). The zip files for these cores contain an ‘OrthogonalViews’ subfolder with reconstructed TIFF images of the split core, and a ‘SliceViews’ text file with directory information for raw data. The raw data (axial slice TIFF images) for these 7 split core scans can be found in the ‘SliceViews’ subfolder of ‘TN403_SplitCores_CT.zip’. Person who carried out this activity:

  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?
    The core depths listed in the Geotek software’s proprietary metadata files are not corrected for sediment compaction and are relative to the surface of the sediment. No formal attribute accuracy tests were conducted.
  2. How accurate are the geographic locations?
    The locations of push core samples were determined using ROV Jason’s ultra-short baseline (USBL) navigation. Accuracy for this depth is approximately 6-26 m. The locations of gravity core samples were determined using the R/V Thomas G. Thompson’s GPS navigation, which is accurate to less than 5 m. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted.
  3. How accurate are the heights or depths?
    For push core samples, the vertical accuracy was determined with ROV Jason’s altimeter, which is accurate to less than 1 m. For gravity core samples, the vertical accuracy was determined with the R/V Thomas G. Thompson’s multibeam bathymetry system. No formal positional accuracy tests were 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?
    Relative variability in CT density was consistent with visual changes in sediment composition.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
