Project 655 - Toarcian Oceanic Anoxic Event: Impact on marine carbon cycle and ecosystems

IGCP project meeting in 2019

3rd International Workshop on the Toarcian Oceanic Anoxic Event (3rd IW-TOAE)

  • 2-5 September 2019, Erlangen (Germany)

The Workshop is open to members of the IGCP 655 and anybody interested in the biotic crisis related to the Pliensbachian-Toarcian boundary and the TOAE. The workshop should be of interest to both academic and industrial participants.

It is specifically open to young researchers students and researchers coming from emerging countries. The meeting will be hosted by the Geozentrum Nordbayern.

Brief outline of the project

The aim of this IGCP Project is the characterization and interpretation of the palaeoenvironmental changes related to the biotic crisis occurred during the Early Jurassic, mainly linked to the Toarcian Oceanic Anoxic Event (T-OAE). The approach to this event will be boarded by diverse researchers from multidisciplinary analysis taking into account biotic (microfossils, macroinvertebrates and vertebrate assemblages) and abiotic data (sedimentology, cyclostratigraphy, mineralogy, elemental geochemistry, organic geochemistry and isotopic geochemistry) from the stratigraphic record from many sections over the world. The T-OAE was related to increasing CO2, global warming and sea-level rise and produced an important extinction mainly on marine ecosystems.

This kind of multidisciplinary approach will provide important information for the History of Climatic Changes and contribute to a better understanding of causes, effects and recovery of climatic changes in the past that can be applied to current studies.

This project will improve the contact and collaboration among scientists working on deciphering the origin of these environmental changes, the impact on marine ecosystems and the recovery after the event. The analysis of catastrophic events that affected the ecosystems of the past allow us to learn and to establish models for identifying and correcting present and future environmental changes.
