Coastal methane emissions driven by aerotolerant methanogens using seaweed and seagrass metabolites - Nature Geoscience

Experiments suggest aerotolerant archaea produce methane in the surface layers of coastal sandy sediments and that this activity is driven by seaweed and seagrass metabolites.

Review of methane through space and time, coauthored with @planetdr.bsky.social, is out (OA) in @annualreviews.bsky.social.

Hopefully a helpful resource for community and courses. www.annualreviews.org/content/jour...

Schematics of atmospheric CH4 cycling on (a) modern Earth, (b) Archean Earth, and (c) Titan. (a) On modern Earth (20% O2), CH4 emissions originate primarily from wetlands, ruminants, and the fossil fuel industry. Methane is oxidized chemically in the troposphere by hydroxyl radicals (OH), with an average lifetime of 10 years. Hydroxyl radicals originate from reactions between ozone (O3), UV radiation (<320 nm), and H2O vapor. The O3 layer originates from reactions between UV radiation and O2. (b) On the Archean Earth (<0.0001% O2), in the absence of O3 and O2, CH4 would have had a much longer atmospheric lifetime (∼10,000 years), with eventual destruction by UV photolysis, leading to H escape and/or, when CH4/CO2 was greater than 0.1, polymerization to yield organic haze in the upper atmosphere. (c) On Titan, with temperatures near the CH4 triple point, there is a CH4 cycle of evaporation, photolysis to yield ethane (C2H6) and H2 (lost to space), and condensation of C2H6, whereupon it participates in surface processes.
