Coastal ecosystems can efficiently remove carbon dioxide (CO) from the atmosphere and are thus promoted for nature-based climate change mitigation. Natural methane (CH) emissions from these ecosystems may counterbalance atmospheric CO uptake. Still, knowledge of mechanisms sustaining such CH emissions and their contribution to net radiative forcing remains scarce for globally prevalent macroalgae, mixed vegetation, and surrounding depositional sediment habitats.

- Coastal methane emissions significantly impact the global methane budget and can limit the carbon storage potential of coastal ecosystems, but current estimates are unreliable due to insufficient high-resolution and long-term data.
- Research shows that methane concentrations in coastal habitats vary widely across meter-scales and fluctuate over time, exhibiting extreme variations and unique seasonal and daily patterns depending on habitat type.
- To accurately assess methane emissions and variability, about 50 measurement samples per day are necessary; the study emphasizes that previously overlooked northern temperate coastal areas are essential sources of atmospheric methane, especially during summer months.
We demonstrate direct eddy covariance (EC) observations of methane (CH) fluxes between the sea and atmosphere from an icebreaker in the eastern Arctic Ocean. EC-derived CH emissions averaged 4.58, 1.
