Gaseous elemental mercury (GEM) over the Kara to East Siberian Seas (Sep–Oct 2024) ranged 0.73–1.32 ng m−3 (mean 0.97), with methane seep evasion fluxes up to 3.5 ng m−2 h−1.
- Why it matters: Arctic warming and complex mercury cycling make it unclear where GEM originates and how much sea-air exchange contributes, especially near potential hotspots like methane seeps.
- What they did: Continuous GEM measurements were made during a cruise across the Kara, Barents, Laptev, and East Siberian Seas, with backward and concentration-weighted trajectories used to identify three potential source regions.
- The result: Sea-air GEM evasion over active methane seeps reached 3.5 ng m−2 h−1, but ship thruster operation enhanced measured fluxes by a factor of 1.3–1.7, so seep attribution remains exploratory.
