Short summary
Sunlight-initiated photochemistry plays an important role in carbon and trace gases cycling in natural waters. We for the first time confirm that photochemical degradation of dissolved organic carbon (DOC) can produce methane, which is the second most important greenhouse gas in the atmosphere. Dissolved oxygen greatly affects the rates of DOC photodegradation and methane photoproduction. The implications of methane photoproduction for methane cycling in modern and ancient oceans are discussed.
