    "descript": "This portion of the data release presents linescan images (photographs) from push cores and gravity core sections collected from the Escanaba Trough vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 (USGS Field Activity 2022-621-FA). Images were obtained from 18 gravity core sections and 39 push cores at 50-micron (200 pixel per cm) resolution. Color images in 16-bit TIFF format are provided for each core segment, along with proprietary metadata files containing image scaling information. Push core images contain an additional TIFF image with a centimeter scale ruler (denoted with _R in filename).",

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."
