The marine environment is being profoundly modified by climate change. Changes in physical and chemical conditions will cascade on ecosystems with consequences that remain difficult to project. Biogeochemical models are key tools for the exploration of possible future states of marine ecosystems. These models have gained in complexity over the past two decades to become simplified representations of first levels of the marine foodweb. The development of models is paralleled by the development of molecular biology, the “omics” revolution. The potential of these novel observations to further our understanding of responses of organisms to environmental changes, but also to drive the development of the next generation of marine biogeochemical/ecosystem components of Earth system models only starts to be exploited. In this lecture I will present the concept of “seascapes”, a possible structuring basis to guide future model development and data analysis. I will report on studies exploring ways to link omics data and biogeochemical models.
About the speaker:
Marion Gehlen (IPSL/LSCE, Gif-sur-Yvette, France) is an ocean biogeochemical modeller. Her research foci include climate change impacts on ocean processes, ocean acidification impacts on marine biogeochemical cycles, ecosystems and feedbacks, recent past and future evolution of the marine carbon cycle, as well as predictability of biogeochemical state and its variability. She is an SSC member of the FutureEarth core project IMBER. She is well known to the Bergen community also as a core theme leader of the EU projects CARBOOCEAN, CARBOCHANGE, and COMFORT, as well as BCCR SAC member.
Time: 4 November, 9.30 AM at BCCR lecture room 4020, Jahnebakken 5, 4th floor.
