Session Proposal: Water Isotope Systematics: Improving Understanding of Past, Present, and Future Hydroclimate (AGU25)

PP034
Water Isotope Systematics: Improving Understanding of Past, Present, and Future Hydroclimate

Session ID#: 247471

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, present, and future 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 machine learning-based methods, and advances in theoretical descriptions of isotopic processes have enabled a wide array of new research questions to be addressed. This session welcomes papers that focus on in-situ and satellite measurements, numerical modeling, or the application of water isotopes to improve our understanding of both the mean state and extreme events of past, present, and future hydroclimate.
