Аннотация
Mud volcanoes are a source of greenhouse gas emissions into the atmosphere. We carried out gas-geochemical monitoring at the Gladkovsky and Oldenburgsky's mud volcanoes for the first time. It was found that the flow rate of mud volcanic gases from salses is much more variable than their chemical composition. In various salses of the same volcano, the chemical composition of mud volcanic gases has significant differences. The measured CH4 flow from macroseeps (salses) is 0.5±0.1 and 2.84±0.32 t/year for Gladkovsky and Oldenburgsky's volcanoes, respectively. The theoretical estimate of CH4 total flow (from mini- and macroseeps) is about 5 and 6 t/year for Gladkovsky and Oldenburgsky's volcanoes, respectively. The Bernard's coefficient for mud volcanic gases shown to be inversely correlated to their emission rate.
