Short summary
Mercury exchange between the ocean and atmosphere is poorly understood due to limited in situ data. Here, using atmospheric mercury observations from ground-based monitoring stations along with air mass trajectories, we found that atmospheric Hg levels increase with air mass ocean exposure time, matching predictions for ocean Hg emissions. This finding indicates that ocean emissions directly influence atmospheric Hg levels and enables us to estimate these emissions on a global scale.
