PP52B:
Water Isotope Systematics: Improving Modern and Paleoclimate Interpretations II

Submit an Abstract to this Session



Session ID#: 33952

Session Description:
Stable isotope ratios of hydrogen and oxygen in water are powerful tools for understanding the earth system, yielding unique insights into the dynamics of past and present climates. Indeed, studies employing water isotopes have provided records of past and present climate change, tracers of hydrologic sources and sinks, and indicators of physical processes in the atmosphere and biosphere. Recently, innovative techniques allowing for water isotope measurements at high temporal frequencies and large spatial scales, new capabilities in simple and complex modeling frameworks, and advances in theoretical descriptions of isotopic processes have enabled a wide array of new research questions to be addressed. This session welcomes any paper that focuses on the measurement, modeling, or application of these water isotopes to better understand past and modern climate dynamics and hydrology.
