SS-36 New insights into the study of episodes of abrupt environmental change in deep time
Convenors: Ricardo Silva (ricardo.silva@umanitoba.ca), Alina Shchepetkina (ashchep@uwo.ca), Muditha Goonetilleke
Since life emerged, Earth witnessed several episodes of abrupt change in the surface environment and biosphere. These included the Great Oxidation Event, mass extinctions, ocean anoxic events (OAEs), rapid climate warming/cooling episodes, and multiple other “sub-lethal” biotic crises. These episodes often coincide with perturbations in biogeochemical cycles and significant changes in internal and external geodynamic processes.
The study of abrupt environmental, climatic, and biogeochemical changes is complex. Although there are still considerable areas for improvement in our understanding of these critical events, progress has been made in uncovering some of the processes and feedback between the various Earth system components during these geological intervals. By unravelling these complex relationships, we gain a better understanding of how the Earth operates as an integrated system and add valuable insights into the future evolution of our planet.
We look forward to receiving your contributions towards researching these critical events, like the Great Oxidation Event, OAEs, Paleocene–Eocene Thermal Maximum, the end Permian and K/Pg extinctions, hyperthermals, etc. Additionally, insights into environment-biological interactions during periods of rapid transformation in the Phanerozoic are appreciated.
