With this project, we aimed to evaluate the temporal dynamics of Hg in three adjacent streams draining different landscape types--peatland-rich, peatland-forest mixed, and forest or meadow only. The main objectives of this study are to (1) measure Hg concentrations in water, sediment, and biota of three streams in Glacier Bay National Park and Preserve (GBNPP), Alaska, and to assess differences in Hg and MeHg (if any) among the streams, (2) examine the extent of temporal variation in concentrations and fluxes of total Hg and MeHg in the streams over an annual time period, and (3) provide a detailed baseline dataset for three streams in GBNPP to which future contaminant monitoring efforts may be compared. This report contains water-quality and climate data collected by the U.S. Geological Survey (USGS) and other agencies from November 2009 to October 2011 at three stream sites, one atmospheric deposition site, and one climate station in GBNPP. Because some of the data presently (2012) cannot be stored in the USGS National Water Information System (NWIS), this report provides a single source to disseminate data that might not otherwise be available to the public.
