Isotope Ratios for Taylor Valley Streams

Summary

Abstract: 

As a part of the McMurdo Dry Valleys LTER program, isotope ratios have been determined for 166 samples of stream water in Taylor Valley, Antarctica. Hydrogen/deuterium isotope ratios are given for all samples, and for a subset, there are oxygen isotope ratios, and a deuterium-excess. Values are reported relative to VSMOW, +/- 1.0 per mil for hydrogen, and +/- 0.1 for oxygen.
