Data Series 169
The image above shows locations of water data in the Western United States. Clicking on it will take you to the data search from an image page. Requires the Flash plug-in.
Chemical and isotope data accumulated by two USGS Projects (led by I. Barnes and R. Mariner) over a time period of about 40 years can now be found using a basic web search or through an image search (left). The data are primarily chemical and isotopic analyses of waters (thermal, mineral, or fresh) and associated gas (free and/or dissolved) collected from hot springs, mineral springs, cold springs, geothermal wells, fumaroles, and gas seeps. Additional information is available about the collection methods and analysis procedures.
The chemical and isotope data are stored in a MySQL database and accessed using PHP from a basic search form below. Data can also be accessed using an Open Source GIS called WorldKit by clicking on the image to the left. Additional information is available about WorldKit including the files used to set up the site.
Systems requirements: Standard web browser. The search from the image page requires flash.
We gratefully acknowledge the chemists and laboratory technicians who produced the chemical, gas, and isotope values listed in the accompanying tables. Water analyses are principally the work of T.S. Presser, W.C. Evans, M. Huebner, J.B. Rapp, and L.M. Wiley. Gas analyses are principally by W.C. Evans with the earlier analyses by J.B. Rapp. Hydrogen, oxygen, nitrogen, and stable carbon isotope analyses are principally the work of L.D. White either in the Jim O'Neil USGS Laboratory in Menlo Park or the Ivan Barnes USGS Laboratory in Menlo Park. Samples for oxygen isotopes of sulfate were prepared by Cathy Janik and run by L.D. White. A few samples for hydrogen and oxygen isotopes on water were run in the Tyler Coplen USGS Laboratory in Reston, Virginia. Lead and strontium isotope analyses were run by Tom Bullen and John Fitzpatrick in the USGS Water Resources Radiogenic Isotope Laboratory in Menlo Park. Helium isotope values were run by Thijs van Soest or Mack Kennedy in Lawerence Berkeley National Laboratory, Berkeley, California. Tritium analyses are by Bob Michaels in the Carol Kendall USGS Isotope Laboratory in Menlo Park, CA or the Denver, CO USGS Tritium Laboratory.Contact Information: Robert Mariner
