Short summary
Precipitation-based deposition of mercury and other trace metals throughout Alaska provides a significant input of pollutants. Deposition shows significant seasonal and spatial variability, largely driven by precipitation patterns. Annual wet deposition of Hg at all AK collection sites is consistently lower than other monitoring stations throughout the CONUS. Hg showed no clear relationship to other metals, likely due to its highly volatile nature and capability of long-range transport.
