Short summary
Methane (CH4) bubbles emitted from the anoxic sediments of northern lakes constitute a significant methane flux to the atmosphere, but entrapment by seasonal lake ice impedes bubble release to the atmosphere. Using numerical modeling and field measurement of a lake in Alaska, we found that 80% of CH4 in ice-trapped bubbles dissolves into the water column. Microbes consume half of that CH4. Emission by bubbling is greatest in summer but continues in winter through some open holes in lake ice.
