  "description": "Water stable isotope ratios (<delta>2H and <delta>18O) from the Willamette River Basin in Oregon, USA.  Isotope values in the Willamette River are from both Portland and Corvallis Oregon, and were collected once or twice a month for 13 years (2011 - 2013).  Isotope data are provided for small spatially distributed watersheds across the basin and samples were collected once a year during summer lowflow, and used to test the temporal stability of the Willamette River Basin Isoscape developed in the following paper: Brooks, J. R., Wigington, P. J., Phillips, D. L., Comeleo, R., & Coulombe, R. (2012). Willamette River Basin surface water isoscape (d18O and d2H): temporal changes of source water within the river. Ecosphere, 3(5), 39. doi: http://dx.doi.org/10.1890/ES11-00338.1  In addition, precipitation isotopes from Corvallis and Newport were collected weekly. \n\n",
