Introduction to the Database

Image of western United States with circles indicating sites to click for more data.

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 the basic search below. 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.
