Summary

During the spring and summer of 2015, the U.S. Geological Survey participated in India’s National Gas Hydrate Program NGHP-02 expedition in the Krishna-Godavari Basin offshore eastern India. The expedition included conventional and pressure coring of sediment, samples of which were transferred to the U.S. Geological Survey in Woods Hole, MA for post-cruise testing. This data release contains measurement results for physical properties measured on recovered core material, including measurements on gas-hydrate-bearing sediment preserved in pressure cores, and physical properties of gas hydrate-free sediment recovered from conventional cores. This work is part of an international NGHP-02 collaboration culminating in a comprehensive collection [...]

Purpose

The coring sites chosen for NGHP-02 target a range of subsurface geologic settings in the Krishna-Godavari Basin offshore eastern India. Previous research has indicated a connection between the sediment grain size distribution and the capacity for that sediment to host gas hydrates. The grain size data in this data release are used to advance the understanding of lithological controls on the distribution and concentration of gas hydrate within the geologic framework established by the NGHP-02 sites. As shown in the browse graphic, gas hydrate occurs primarily in the low clay-content sediment (1-4R), not the coarsest sediment (e.g. 1I, 3I).
