Exploring the Nexus of Past Climate, Environment, and Humans: Combining Molecular Tools and Other Novel Proxies, Techniques, and Methods
Session ID#: 162218
Session Description:
While gaining a better understanding of past climate-human-environment interactions is a challenge, it is crucial in order to assess the future of the earth system under anthropogenic activities. Recent methodological advances allow for the high-resolution analyses of molecular compounds and physical properties in natural chronostratigraphic archives, which offer different perspectives into paleoenvironmental histories. The combination of multiple proxies along with the employment of novel data analysis tools provide more comprehensive insights into paleoclimatic conditions.
In this session we aim at fostering interdisciplinarity connections between researchers in paleoclimatology, biogeochemistry, geomicrobiology, archaeology, etc. We particularly encourage submissions that (1) combine lipid biomarkers and other novel proxies (e.g., DNA), (2) apply new analytical approaches, including hyperspectral imaging techniques and other cutting-edge high-resolution techniques (e.g., μXRF, SEM, CT-scans), (3) use new computational and/or statistical methods (e.g., machine learning), (4) utilize proxies providing unique insights in the history of past human activities, and associated ecosystem and environmental changes.
