PP24B:
Water Isotope Systematics - Improving Modern and Paleoclimate Interpretations III

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17487

Session Description:
Isotopes of hydrogen and oxygen are powerful and unique tools for understanding the earth system.  This includes acting as recorders of past climate change, tracers of hydrologic sources and sinks, and indicators of physical processes in the atmosphere and biosphere.  New techniques that allow for the observation of water isotopes at high temporal frequency and large spatial scales, combined with new theoretical and modeling capabilities, allow for a wide array of new research possibilities.  This session welcomes any paper that focuses on the measurement, modeling, or application of these water isotopes to better understand past and modern climate and hydrology.
