Oceanic evasion fuels Arctic summertime rebound of atmospheric mercury and drives transport to Arctic terrestrial ecosystems by Shaojian Huang, Tengfei Yuan, Zhengcheng Song, Ruirong Chang, Dong Peng, Peng Zhang, Ling Li, Peipei Wu, Guiyao Zhou, Fange Yue, Zhouqing Xie, Feiyue Wang, Yanxu Zhang

“…Enhanced Hg0 dry deposition across the Arctic coastal regions, especially in the Arctic tundra, during the summer rebound highlights the potential transport of Hg from the pristine Arctic Ocean to Arctic terrestrial ecosystems. Arctic warming, with a transition from multi-year to first-year ice and tundra greening, is expected to amplify oceanic Hg evasion and intensify Hg0 uptake by the Arctic tundra due to increased vegetation growth, underlining the urgent need for continued research to evaluate Hg mitigation strategies effectively in the context of a changing Arctic.…”

“…To collect data that help to constrain the models, the HALO–(<span class="inline-formula">𝒜𝒞</span>)<span class="inline-formula">³</span> aircraft campaign was conducted over the Norwegian and Greenland seas, the Fram Strait, and the central Arctic Ocean in March and April 2022. The campaign focused on one specific challenge posed by the models, namely the reasonable representation of transformations of air masses during their meridional transport into and out of the Arctic via northward moist- and warm-air intrusions (WAIs) and southward marine cold-air outbreaks (CAOs). …”
