    "descript": "This portion of the data release presents computed tomography (CT) images from push cores collected from Loki's Castle and Favne vent fields, on the Mohns Ridge, in the Norwegian Sea. These data were collected in 2018 and 2019 (USGS Field Activity 2018-691-DD and 2019-624-FA). 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.",

Distributions are recorded observations or models of mineral grain size, composition, and deposit thickness in a location or area, including maps of these resources derived through observations, interpreted data, remote sensing data, geologic maps, and hydrodynamic models. Assessments are evaluations of total mineral availability; models of present deposition, resuspension, erosion, or accretion; models of difficulty of extraction or relocation; and models of ecological and economic values. Predictions are the results of models or projections of future distributions, values, or ecological impacts of mineral resources; these data include predicted changes due to natural and human forces. Predictions are also the results of scenario-based models of resource losses, gains, or impacts on ecological or economic values under different management strategies (for example, mining, extraction, or relocation) or other human alterations."
