NEWS:
GSA Special Session

T41. High-Resolution Terrestrial and Marine Geochemical Proxies of  
Global Change: Problems, Progress and Utility (see rationale below),  
aims to highlight new research from terrestrial and aquatic (marine  
and freshwater) environmental and climatic proxies. We have  
commitments from invited speaks which will present data from diverse  
substrates such as corals (Hali Kilbourne), tree-rings (Kevin  
Anchukaitis) and bivalves/ otoliths (Anne Lorrain).

The abstract deadline is fast approaching (August 11!) and we hope  
that you will consider submitting an abstract to what is likely to be  
a stimulating and informative session. More information about the  
meeting can be found here: http://www.geosociety.org/meetings/2009/

If you have any questions please feel free to contact us.

Best regards,

*SESSION RATIONALE: *
High-resolution elemental, isotopic, and growth data preserved in  
bioarchives and inorganic carbonates are important proxies of  
environmental, ecological, and physiological conditions throughout  
geologic time. However, many of these proxies still need to be  
calibrated/validated with instrumental records before they can be  
confidently utilized in paleoenvironmental studies. We would like to  
attract papers utilizing geochemical signals in biological carbonates  
(e.g., molluscs, brachiopods, corals, sponges, algae), abiogenic  
carbonates (e.g., speleothems) and other bioarchives (e.g., trees),  
which can be used to study past environmental change at high- 
resolution. Studies focusing the life history and ecology of these  
organisms and/or the calibration and validation of these potential  
geochemical proxies are also welcome. Unfortunately, many research  
groups which focus on one substrate (e.g., molluscs) do not  
intermingle with researchers working on other substrates (e.g.,  
trees).  The objective of this topical session is to convene the paleo- 
community with geochemists, and biologists working on diverse  
substrates to present recent findings on the nature, interpretation,  
and utility of such geochemical archives.
