PCCT measurements of stress and strain during direct shear tests of fine-grained sediment collected from Area C, Krishna-Godavari Basin during India's National Gas Hydrate Program, NGHP-02
Understanding how effectively methane can be extracted from a gas hydrate reservoir requires knowing how compressible, permeable, and strong the overlying seal sediment is. This data release provides results for flow-through permeability, consolidation, and direct shear measurements made on fine-grained seal sediment from Site NGHP-02-08 offshore eastern India. The sediment was collected in a pressure core from the Krishna-Godavari Basin during the 2015 Indian National Gas Hydrate Program Expedition 2 (NGHP ... |

Grain size analysis and total carbon content of augered sediment samples from Barter Island, Alaska
This data release contains grain size and total carbon analysis of sediment samples from 1 inch hand-augered cores collected from Barter Island, Alaska. These data were collected in 2016 and 2019 (USGS Field Activity 2016-645-FA and 2019-634-FA). Data include location information (latitude, longitude, depth), and the weight percent of 65 phi bins, four size fractions (gravel, sand, silt, clay), total carbon, inorganic carbon, organic carbon, and calcium carbonate. |
