Abstract:
Eight methane hydrate samples for analysis of gas compositions, bulk stable isotopes and methane clumped isotope are collected from the Site GMGS2-08 during the second Gas Hydrate Drilling Expedition of Guangzhou Marine Geological Survey (GMGS2), Dongsha Sea area of northern South China Sea. Abundances of singly and doubly-substituted isotopologues of methane (13CH4, 12CH3D, 13CH3D, and 12CH2D2) are measured on a Panorama (Pan004), an ultra–high–resolution gas–source multiple collector Mass Spectrometer at Guangzhou Institute of Geochemistry (GIG).
