Characteristic Settling Time and Interface Height Dependence on Pore Fluid Chemistry for Sediment Collected From Area B, During India's National Gas Hydrate Program Expedition NGHP-02

One goal of the Indian National Gas Hydrate Program's NGHP-02 expedition was to examine the geomechanical response of marine sediment to the extraction of methane from gas hydrate found offshore eastern India in the Bay of Bengal. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages in a lattice of water molecules. Methane gas hydrate is a potential energy resource, but whether extracting methane from gas hydrate in the marine subsurface is technically and economically viable remains an open research topic as of 2018. This data release provides insight about a poorly quantified aspect of this process: the reaction of fine-grained sediment particles (fines) to the change [...]
