dc.description.abstract In the eastern mud-belt of Korea, geophysical and geochemical survey from sedimentary layer and water column were performed to confirm the shallow gas accumulation gas release feature.The active seepage of hydrocarbon gases has been observed by high-resolution (3.5 kHz) seismic profiling both in March and July 2007, occurring through a large number of plumes from the topmost sedimentary layer. The gas seepage appears to be explosive to form craters, although pockmarks are rare. In water column and sediments, the stable carbon isotopes in gases are characterized by large difference between δ13C (-59.8 to -48.6 ‰ PDB) and δ13C (-62.0 to -39.7‰ PDB) values, respectively. The biogenic gases are considered to be generated from high amount of organic carbon (1.5-4.0%) in the sedimentary layer with mixing of small amount of thermogenic gas which derived through faults. -
