BG6.1 Multiproxy organic geochemical and micropalaeontological appoaches in Earth Sciences |
Conveners: Jung-Hyun Kim , Carme Huguet | Co-Convener: Carys Bennett |
Microfossils can often be recovered in large quantities from relatively small samples. Diatoms, pollen, foraminifera, dinoflagellates, ostracods, chironomids and others are picked, identified and enumerated and eventually lead to a comprehensive and often detailed interpretation of the past environment. Multiproxy micropalaeontological approaches are increasingly common but it is not always easy to find interpretations that are consistent with the indications of all the proxies utilized, and such studies would often benefit from a more critical consideration of the assumptions and limitations of the methods used. The aim of this session is to explore the potential and constrains of biomarker-based proxies in palaeoceanographic and palaeoclimatic studies. We invite presentations of palaeoenvironmental studies (marine and freshwater) that focus on two or more biological proxy groups and their interpretation; we particularly welcome critical evaluations of the effectiveness of multiproxy approaches.
