Stable Hydrogen and Oxygen Isotope Ratios for Selected
Sites of the U.S. Geological Survey's NASQAN and Benchmark
Surface-water Networks
U.S. Geological Survey Open-File Report 00-160, Version 1.0
By Tyler B. Coplen and Carol Kendall
Abstract
Increasingly, hydrologic studies require information on the
isotopic composition of natural waters. This report presents
stable hydrogen (delta2H) and oxygen isotope
ratios (delta18O) from 391 selected sites of the
U.S. Geological Survey's National Stream Quality Accounting
Network (NASQAN) and BENCHMARK surface water networks
collected during the years 1984-1987. Depth-integrated
samples were collected and analyzed from each site bimonthly
or quarterly for about 3 years.
