Coastal Upwelling Regions in Past Oceans: Paleoreconstructions from Proxies and Biogeochemical Modelling





Session ID#: 25819

Session Description:
Coastal upwelling regions play an important role in marine ecosystems and in global biogeochemical cycling. They have a strong socioeconomic impact, since they are most important areas for commercial fisheries due to their high productivity. Anthropogenic climate change strongly impacts these regions including ongoing deoxygenation, which influences global nutrient inventories. Understanding the sensitivity of these environments to climate change in the past is crucial for the prediction of potential future scenarios. Paleoenvironmental reconstructions from these regions of high productivity have been focused on a wide range of micropaleontological and (isotope-) geochemical proxies as well as biomarkers. The integration of biogeochemical modelling with proxy data will also improve the understanding of past ocean productivity and nutrient cycles. For this session, we invite submissions of studies aiming at the reconstruction of coastal upwelling ecosystems, surface productivity and redox conditions based on proxy applications as well as modelling approaches.
