    • Mercury isotope evidence for Arctic summertime re-emission of mercury from the cryosphere 

      Araujo, Beatriz Ferreira; Osterwalder, Stefan; Szponar, Natalie; Lee, Domenica; Petrova, Mariia V.; Pernov, Jakob Boyd; Ahmed, Shaddy; Heimbürger-Boavida, Lars-Eric; Laffont, Laure; Teisserenc, Roman; Tananaev, Nikita; Nordstrom, Claus; Magand, Olivier; Stupple, Geoff; Skov, Henrik; Steffen, Alexandra; Bergquist, Bridget; Pfaffhuber, Katrine Aspmo; Thomas, Jennie L.; Scheper, Simon; Petäjä, Tuukka; Dommergue, Aurélien; Sonke, Jeroen E. (Peer reviewed; Journal article, 2022)
      During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0), which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak that is thought to result mostly from terrestrial ...

      Cohen, Mark D.; Draxler, Roland R.; Artz, Richard S.; Blanchard, Pierrette; Gustin, Mae Sexauer; Han, Young-Ji; Holsen, Thomas M.; Jaffe, Daniel A.; Kelley, Paul; Lei, Hang; Loughner, Christopher P.; Luke, Winston T.; Lyman, Seth N.; Niemi, David; Pacyna, Jozef M; Pilote, Martin; Poissant, Laurier; Ratte, Dominique; Ren, Xinrong; Steenhuisen, Frits; Steffen, Alexandra; Tordon, Rob; Wilson, Simon J. (Journal article; Peer reviewed, 2016)

    • Modelling the coupled mercury-halogen-ozone cycle in the central Arctic during spring 

      Ahmed, Shaddy; Thomas, Jennie L.; Angot, Hélène; Dommergue, Aurélien; Archer, Stephen D.; Bariteau, Ludovic; Beck, Ivo; Benavent, Nuria; Blechschmidt, Anne-Marlene; Blomquist, Byron; Boyer, Matthew; Christensen, Jesper H.; Dahlke, Sandro; Dastoor, Ashu; Helmig, Detlev; Howard, Dean; Jacobi, Hans-Werner; Jokinen, Tuija; Lapere, Rémy; Laurila, Tiia; Quéléver, Lauriane L.J.; Richter, Andreas; Ryjkov, Andrei; Mahajan, Anoop S.; Marelle, Louis; Pfaffhuber, Katrine Aspmo; Posman, Kevin; Rinke, Annette; Saiz-Lopez, Alfonso; Schmale, Julia; Skov, Henrik; Steffen, Alexandra; Stupple, Geoff; Stutz, Jochen; Travnikov, Oleg; Zilker, Bianca (Peer reviewed; Journal article, 2023)
      Near-surface mercury and ozone depletion events occur in the lowest part of the atmosphere during Arctic spring. Mercury depletion is the first step in a process that transforms long-lived elemental mercury to more reactive ...

    • Updated trends for atmospheric mercury in the Arctic: 1995–2018 

      MacSween, Katrina; Stupple, Geoff; Aas, Wenche; Kyllönen, Katriina; Pfaffhuber, Katrine Aspmo; Skov, Henrik; Steffen, Alexandra; Berg, Torunn; Mastromonaco, Michelle N. (Peer reviewed; Journal article, 2022)
      The Arctic region forms a unique environment with specific physical, chemical, and biological processes affecting mercury (Hg) cycles and limited anthropogenic Hg sources. However, historic global emissions and long range ...
