Water and gas chemistry data from: Mariner, R.H., Swanson, J.R., Orris, G.J., Presser, T.S. and Evans, W.C., 1980. Chemical and isotopic data for water from thermal springs and wells of Oregon: U.S. Geological Survey Open File Report 80-737, 53 p., https://doi.org/10.3133/ofr80737. Water chemistry data was digitized for 184 samples. Reported attributes include: Sample name, Type, Collection date, Reported location, Reported latitude, Reported longitude, State, County, Latitude, Longitude, Location resolution, Location error, Source, Temperature, pH, Aluminum (Al), Boron (B), Bromine (Br), Calcium (Ca), Chloride (Cl), Cesium (Cs), Fluoride (F), Iron (Fe), Alkalinity as bicarbonate (HCO3), Mercury (Hg), Iodide (I), Potassium (K), Lithium (Li), Magnesium (Mg), Manganese (Mn), Sodium (Na), Nitrate (NO3), Rubidium (Rb), Silica (SiO2), Sulfate (SO4), Strontium (Sr), Cations, Anions, Salinity, Charge balance, Specific conductance, Isotopic composition of hydrogen (Delta 2H), Isotopic composition of oxygen in water (Delta 18O H2O), Isotopic composition of oxygen in water (Delta 18O SO4), Author comment, Digitizer comment. Gas chemistry data was digitized for 23 samples. Reported attributes include: Sample name, Type, Collection date, Reported location, Reported latitude, Reported longitude, State, County, Latitude, Longitude, Location resolution, Location error, Source, Temperature, Total gas, Argon (Ar), Oxygen and argon (O2 + Ar), Methane (CH4), Carbon dioxide (CO2), Nitrogen (N2), Oxygen (O2), Digitizer comment. Data was digitized from Tables 1, 2, and 3. The following tables were not digitized: Table 2 (partial): topographic map coverage. Table 4: estimated aquifer temperature. The data represents a subsection of data previously stored in the U.S. Geological Survey's GEOTHERM computer resources database. GEOTHERM was in use from 1977 - 1983 (United States Geological Survey, 1983; Swanson, 1977). The complete GEOTHERM database can be retrieved from the Geothermal Data Repository at: https://doi.org/10.15121/1149729 (United States Geological Survey, 1983). The GEOTHERM open-file report can be found at: https://doi.org/10.1016/0098-3004(83)90034-1 (Bliss and Rapport, 1983). References: Bowen, R. G., Peterson, N. V., and Riccio, J.
