Pathways of methane removal in the sediment and water column of a seasonally anoxic eutrophic marine basin

Frontiers in Marine Science, 2023
Methane (CH4) is a key greenhouse gas. Coastal areas account for a major proportion of marine CH4 emissions. Eutrophication and associated bottom water hypoxia enhance CH4 production in coastal sediments.
