Dataset of diatom controls on the sedimentation behavior of fine-grained sediment collected offshore of South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2 One of the primary goals of South Korea’s second Ulleung Basin Gas Hydrate Expedition (UBGH2) was to examine the geotechnical properties of the marine sediment associated with methane gas hydrate occurrences found offshore of eastern Korea in the Ulleung Basin, East Sea. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages formed by a lattice of water molecules. During UBGH2, concentrated gas hydrate was found in two sedimentary environments: gas hydrate was found in thin, coarse-grained sediment layers interbedded with fine-grained sediment (fines, such as clays and muds) and as veins of essentially pure gas hydrate within predominantly fine-grained...

Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages formed by a lattice of water molecules. Offshore Korea, gas hydrate is found in thin, coarse-grained sediment layers that are interbedded with fine-grained sediment. Methane gas hydrate is a potential energy resource, but whether extracting methane from gas hydrate in these layered marine environments is technically and economically viable remains an open research...

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... Categories: Data; Tags: Bay of Bengal, Geochemistry, Geophysics, Indian Ocean, Krishna-Godavari Basin, All tags...

Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages formed by a lattice of water molecules. During UBGH2, concentrated gas hydrate was found in two sedimentary environments: thin, coarse-grained sediment layers interbedded with fine-grained sediment (fines, such as clays and muds) and as veins of essentially pure gas hydrate within beds of predominantly fine-grained sediment....
