Short summary

In this study we investigated marine algae as a source of CH₄ in oxic surface waters of oceans. Algae-derived CH₄ may explain the CH₄ oversaturating state within the surface mixed layer, sometimes also termed the "oceanic methane paradox". This finding of an overlooked source of CH₄ in marine environments will be of considerable importance to scientists in many disciplines because algae play a crucial role in organic matter cycling in marine and freshwater ecosystems.
