n. 1047: “High methane emissions from an anoxic fjord driven by mixing and oxygenation” by Stefano Bonaglia

Oceanic methane (CH4) budgets lack data from high-latitude fjords that often behave as intermittently anoxic ecosystems with potentially high methane emissions. We conducted 15 expeditions and 49 in situ lander deployments in an anoxic Scandinavian fjord between 2009 and 2021. Benthic fluxes were highest at the deepest anoxic site (average 516 μmol CH4 m−2 d−1), supporting bottom water methane exceeding 5000 nM.
