Statement

Water samples were collected directly from springs and rivers, and in rain collectors. Samples were filtered through 0.2micron PES membranes, with cation samples acidified to pH 2 while anion samples were left unacidified. HCO3- was determined by gran titration in the field. Cations were determined using an Agilent 5100 and anions using a Dionex ICS-5000. Both have an analytical uncertainty of 5%. Some samples were run for minor cations on an iCap-Q ICP-MS with an uncertainty of 10%. Stable water isotopes were measured on a Picarro L2140-i with uncertainties of 0.1,0.15 and 1.2‰ for δ17O, δ18O and δ2H respectively. δ13C was measured on a MAT253 mass spectrometer with uncertainty 0.2‰. Isotopes and uncertainties measured on a Neptune ICP-MS include 87Sr/86Sr (70ppm), δ88Sr (0.03‰), δ30Si (0.06‰) and δ7Li (1‰) Additional 87Sr/86Sr isotopes were made on a TIMS VG Sector 54 (70ppm).
