B21H:
Investigating Biological Processes: Insights from New Stable Isotope Methods I Posters

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#: 12819

Session Description:
This session will bring together biogeochemists, ecologists, atmospheric scientists and paleoclimatologists using isotopologue, isotopomer or clumped isotope signatures of organic molecules to track biochemical and physiological processes in biotic (plants, microbes, and algae) and abiotic (soil, sediment, water, and aerosol) samples across different scales. We encourage people working with all techniques (MS-, NMR- or spectroscopy-based) to present methods and applications on biologically or biogeochemically interesting molecules. This session will offer an overview of what proxies are available and what information can be extracted from them. This session will also provide an opportunity for method and proxy developers to present their researches to scientists eager to use new tools to investigate biological processes such element allocations, plant responses to environmental changes, and ecosystem functioning, opening a dialogue that will enhance insight into the current and the next-generation of cutting-edge techniques to study the Earth system.
