Arctic mercury depletion and its quantitative link with halogens

Gas phase elemental mercury (Hg°) was measured aboard the NASA DC-8 research aircraft during the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) campaign conducted in spring 2008 primarily over the North American Arctic. We examined the vertical distributi...

Zusammenfassung:Gas phase elemental mercury (Hg°) was measured aboard the NASA DC-8 research aircraft during the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) campaign conducted in spring 2008 primarily over the North American Arctic. We examined the vertical distributions of Hg° and ozone (O 3 ) together with tetrachloroethylene (C 2 Cl 4 ), ethyne (C 2 H 2 ), and alkanes when Hg°- and O 3 -depleted air masses were sampled near the surface (
