We obtained samples of natural\ngas hydrate and measured the molecular and isotopic compositions of hydrate-bound gas.\nMethane \u03b413C and \u03b4D were in the range of \uff0d67 to \uff0d63\u2030 and \uff0d207 to \uff0d193\u2030, respectively.\nThese results indicate a microbial origin produced by CO2 reduction according to Whiticar\u0027s diagram.\nBecause ethane \u03b413C showed a thermogenic origin, hydrate-bound gas contains a small\namount of thermogenic gas. The hydration numbers of the samples were estimated as 6.19 \u00b1\n0.02 using the Raman spectra of the C?H stretching mode and a thermodynamic calculation.\nHeat flow calorimetry revealed that the values for dissociation heat of the samples were 18.1 \u00b1\n0.3 kJ mol\uff0d1\uff08 from hydrate phase to gas and ice phases\uff09 and 55.4\u00b10.4 kJ mol\uff0d1\uff08 from hydrate\nphase to gas and water phases\uff09, which agree well with the values in of literature.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "38666", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "HACHIKUBO, Akihiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "38667", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SAKAGAMI, Hirotoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "38668", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "MINAMI, Hirotsugu"}]}, {"nameIdentifiers": [{"nameIdentifier": "38669", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NUNOKAWA, Yutaka"}]}, {"nameIdentifiers": [{"nameIdentifier": "38670", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SHOJI, Hitoshi"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5730\u5b66\u5354\u4f1a"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.5026/jgeography.118.207", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u516b\u4e45\u4fdd, \u6676\u5f18"}], "nameIdentifiers": [{"nameIdentifier": "89765", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "50312450", "nameIdentifierScheme": "KAKEN -
