Abstract: Biogenic methane mitigation systems and methods are provided comprising a floating island having two ends and being comprised of a biofilm-reactive matrix, an airlift system on one or both ends of the floating island, the airlift system comprising one or more pipes or hoses and an aeration system. Macro- and micro-treatment system bubbles are passed under and into the floating island, thereby exposing methane to active methanotroph culture and causing mitigation of the methane. A passive embodiment of the system does not require airlift technology but relies instead on natural or gravity-based circulation of methane containing water or methane in ebullition bubble form into floating island matrix, thereby exposing methane to active methanotroph culture and causing mitigation of the methane. Systems and methods for capturing and harvesting methane also are provided.
