    • Factors Driving Mercury Variability in the Arctic Atmosphere and Ocean over the Past 30 Years 

      Fisher, Jenny A.; Jacob, Daniel James; Soerensen, Anne Laerke; Amos, Helen Marie; Corbitt, Elizabeth Sturges; Streets, David G.; Wang, Qiaoqiao; Yantosca, Robert M.; Sunderland, Elynor M (Wiley-Blackwell, 2013)
      [1] Long-term observations at Arctic sites (Alert and Zeppelin) show large interannual variability (IAV) in atmospheric mercury (Hg), implying a strong sensitivity of Hg to environmental factors and potentially to climate ...
    • Gas-Particle Partitioning of Atmospheric Hg(II) and Its Effect on Global Mercury Deposition 

      Amos, Helen Marie; Jacob, Daniel J.; Holmes, C. D.; Fisher, Jenny Allison; Wang, Qiaoqiao; Yantosca, Robert M.; Corbitt, Elizabeth Sturges; Galarneau, E.; Rutter, A. P.; Gustin, M. S.; Steffen, A.; Schauer, J. J.; Graydon, J. A.; Louis, V. L. St.; Talbot, R. W.; Edgerton, E. S.; Zhang, Y.; Sunderland, Elynor M (Copernicus GmbH, 2012)
      Atmospheric deposition of Hg(II) represents a major input of mercury to surface environments. The phase of Hg(II) (gas or particle) has important implications for deposition. We use long-term observations of reactive gaseous ...
    • Global atmospheric model for mercury including oxidation by bromine atoms 

      Holmes, C. D.; Jacob, Daniel James; Corbitt, Elizabeth Sturges; Mao, J.; Yang, X.; Talbot, R.; Slemr, F. (Copernicus GmbH, 2010)
      Global models of atmospheric mercury generally assume that gas-phase OH and ozone are the main oxidants converting Hg0 to HgII and thus driving mercury deposition to ecosystems. However, thermodynamic considerations argue ...
    • Global Biogeochemical Implications of Mercury Discharges from Rivers and Sediment Burial 

      Amos, Helen Marie; Jacob, Daniel James; Kocman, David; Horowitz, Hannah Marie; Zhang, Yanxu; Dutkiewicz, Stephanie; Horvat, Milena; Corbitt, Elizabeth Sturges; Krabbenhoft, David P.; Sunderland, Elynor M (American Chemical Society (ACS), 2014)
      Rivers are an important source of mercury (Hg) to marine ecosystems. Based on an analysis of compiled observations, we estimate global present-day Hg discharges from rivers to ocean margins are 27 plus or minus 13 Mmol a ...
    • Global Source–Receptor Relationships for Mercury Deposition Under Present-Day and 2050 Emissions Scenarios 

      Corbitt, Elizabeth Sturges; Jacob, Daniel James; Holmes, Christopher D.; Streets, David G.; Sunderland, Elynor M (American Chemical Society (ACS), 2011)
      Global policies regulating anthropogenic mercury require an understanding of the relationship between emitted and deposited mercury on intercontinental scales. Here, we examine source–receptor relationships for present-day ...
