Development of a Laser Spectroscopy System for Analysis of 17Oexcess on Ice Cores
Entry ID: USAP-1341360

Abstract: This award supports a two-year project to develop a method for rapid and precise measurements of the difference in 18O/16O and 17O/16O isotope ratios in water, referred to as the 17O-excess. Measurement of 17O-excess is a recent innovation in geochemistry, complementing traditional measurements of the ratios of hydrogen (D/H) and oxygen (18O/16O). Conventional measurements of 17O/16O are limited ... View entire text
