Multidisciplinary field operations were performed at a study area （approximately\n16 × 20 km2）to investigate seepage characteristics and understand gas hydrate formation\nmechanisms. A continuous profiling survey was conducted to obtain a distribution map of\nseepage structures on the floor by using a deep-tow, side-scan-sonar equipment. The distribution\nmap reveals that the dense area of seepage structures coincides with a sea-floor area of deformed\nsediments caused possibly by repeated sediment slumping and debris flows in the past. We speculate\nthat this deformation may have created shallow faults that are suitable to conduits for the\nmigration and discharge of gas and fluid.\n　　Three seepage structures were selected to study about their fluid-seep conditions around the\nsea floor level. Hieroglyph seepage structure is located at the northern end of the dense area of\nthe structures. Kitami and Chaos structures are located about 2 and 7 km respectively apart\nfrom the Hieroglyph structure within the dense area. Large plumes on echograms and higher\nmethane contents in the water column confirm gas seepage activities at the three structures.\nThere observed at least two and four plumes at the Hieroglyph and Chaos structures, respectively.\nEach gas chimney image in seismic reflection profiles was traced to connect each BSR and\nseepage structure. Both pull-up and disturbed structures of BSR around the gas chimney images\nwere interpreted as to be indications of significant heat flows caused by ascending fluid at\nboth Kitami and Chaos structures. On the other hand, almost no pull-up/disturbance of BSR was observed at the Hieroglyph structure, suggesting little water seepage.\n　　The seep activity may vary with time off the Sakhalin. The Hieroglyph structure is located\nat the edge of a dense area of the seepage structures. It might serve as an indicator for the longterm\nactivity of the fluid seepage system off the Sakhalin.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"38681","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHOJI,
