This portion of the data release presents linescan images (photographs) from push cores collected from Loki's Castle and Favne vent fields, on the Mohns Ridge, in the Norwegian Sea. These data were Rcollected in 2018 and 2019 (USGS Field Activity 2018-691-DD and 2019-624-FA). Images were obtained from seventeen 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.

This portion of the data release presents X-ray fluorescence (XRF) data 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). The XRF data were collected with the sensor in "geochem" mode and are provided in comma-delimited files (.csv).

This portion of the data release presents X-ray diffractograms of sediment subsamples 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). Location information for the sample is included in each Attribute Definition of this metadata file, as well as in the geochemical data table (LokisMohns_marine_mineral_geochemistry.csv) of this multi-table data release.
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...

For more than 25 years, the U.S. Geological Survey Gas Hydrates Project has compiled and maintained an internal database of locations where the existence of gas hydrate has been confirmed or inferred in research studies. The existence of gas hydrate was considered confirmed when gas hydrate was recovered by researchers or videotaped from a vehicle (such as a submersible or remotely operated vehicle) near the sea floor. The existence of gas hydrate was considered inferred when seismic data, borehole logs, or certain geochemical characteristics match anomalies known to characterize gas hydrate. This data release provides a text description of the region, geographic coordinates, and the citation for the published reference...
