High-Resolution Analytical Techniques: Improving our Understanding of Past Climates

Session ID#: 158857

Session Description:
Researchers are now able to generate data from paleoclimate archives at microscale resolution with high precision and accuracy due to significant improvements in instrumentation and refined methodologies such as imagery-correlated analysis. Sampling paleoclimate archives with high spatial and temporal resolution allows for the generation of data and records that were inaccessible to conventional techniques. These high-resolution analytical approaches help to uncover critical processes involved in the formation and preservation of climate signals and thus lead to a better understanding of ‘traditional’ proxy records. We invite contributions from across the paleoclimate community and research encompassing both a broad selection of climate archives (marine microfossils, corals, mollusks, otoliths, teeth, pedothems, speleothems, etc.) and high-resolution analytical techniques (SIMS, LA-ICPMS, EPMA, micro-CT, atom probe, synchrotron, micromill, etc.). This session will provide a forum for new and exciting paleoclimate research as well as for sharing new analytical capabilities and methodological developments.
