Computed tomography (CT) scans of gravity cores and push cores from the Escanaba Trough (Gorda Ridge)
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.
