We will purchase and use a spectroscopic water isotope analyzer that will enhance multiple Caltech projects within the RSI's Climate Science, Water Resources and Ecology and Biosphere Engineering Initiatives. The stable isotope composition of water ( 2H/1H, 17O/16O, and 18O/16O ratios) has very broad utility as a tracer for this ubiquitous compound, and the instrument thus facilitates investigation across many relevant disciplines including: (paleo)climate and meteorology, hydrology, limnology, global biogeochemistry, microbiology, ecology, and soil science.
