PP012:
Deciphering Environmental and Ecological Controls on the Biogeochemistry of Marine Fossils





Session ID#: 23198

Session Description:
As anthropogenic forcing generates unprecedented changes across marine ecosystems, biogeochemical proxies derived from calcareous and siliceous marine fossils become increasingly vital resources for insights into long-term climate change and organismal responses. While many geochemical signals serve as proxies for environmental variables, the influences of ecology and biology (“vital effects”) can convolute these signals (e.g. carbonate system vs. biological controls on foraminiferal B/Ca ratios). Deciphering the ecological and biological components of geochemical signatures in marine fossils and disentangling these from external controls improves our understanding of traditional geochemical proxies. It furthermore increases the potential for development of novel proxies probing ecological, biological or evolutionary responses in the fossil record. We invite studies offering insight into the incorporation and deconvolution of environmental, biological and ecological variables on the geochemistry of marine organisms. We particularly encourage submissions combining methodologies (field/culture-based, modeling, fossil) or incorporating projection of organism responses to future climate scenarios.
