Session 3. Biogeochemical Cycles, Biota and Evolution


 

 

 

Ocean biogeochemistry strongly responds to and impacts climate change. Sediment records from the ocean floor and results from earth system and ocean biogeochemical models are increasingly providing novel insights into the interactions between changes in ocean circulation, biota, temperature, salinity, ocean pH, processes at the land-sea interface and ocean biogeochemical cycles at various spatial and temporal scales.

This session will focus on what we know about these past changes in biogeochemical cycles, ecosystem function and evolution and all relevant interactions with climate. We are interested in both qualitative and quantitative paleoenvironmental reconstructions with an emphasis on the elucidation of mechanisms driving past environmental change and major consequences.

Examples of topics we would like to see include studies of ocean deoxygenation, ocean acidification, ocean carbon dynamics and storage, nutrient cycling, methane dynamics, and trace element and isotope studies (e.g. N, Si, Fe).
