RIV01 Stream water isotopes in wooded riparian areas and areas where canopy had been cut at Konza Prairie

The stream water samples are the same as collected for the NWC01 dataset.  Water samples are frozen (-3 C) in sealed polyvinyl bottles until time of processing. These water samples are thawed, subsampled at 1 mL, and analyzed for delta18O and delta2H using a Picarro L2130-i isotopic water analyzer. Samples are corrected using in-house standards calibrated to the international standard, V-SMOW.  The long-term precision for delta18O is 0.1 permil and for delta2H is 1 permil.
