Dissolved Gas Flux in Yellowstones hydrothermal system

As of January 2007, YVO collects samples of water from Yellowstone's rivers approximately 28 times per year.  These waters are analyzed for a variety of dissolved components such as Cl, F,  Br, SO₄^2- and HCO₃^-. Combined with data on streamflow, these data allow calculation of the amounts of dissolved gases that flow out of Yellowstone's hydrothermal system.  The information is useful for measuring changes to the hydrothermal system caused by meterological, human or geological factors.

Yellowstone Gas Flux Data

Long-term chloride flux 1996-2000 can be found in the electronic data sets in "TIME-VARIATION OF HYDROTHERMAL DISCHARGE AT SELECTED SITES IN THE WESTERN UNITED STATES: IMPLICATIONS FOR MONITORING" by Ingebritsen, S.E., Galloway, D.L., Colvard, E.M., Sorey, M.L., and Mariner, R.H., U.S. Geological Survey, Menlo Park, California 94025." The data are available in PDF and MS Excel format.

Anion flux data since 2002 (Cl, F,  Br, SO₄^2- and HCO₃^-) is updated yearly in Digital Data Series 278: Hurwitz, S., Eagan, S., Heasler, H., and Lowenstern, J.B.,  2007, revised 2009, River chemistry and solute flux in Yellowtone National Park, U.S. Geological Survey Data Series 278, version 3.0: http://pubs.usgs.gov/ds/2007/278/ (File in Excel Format).
