EGU2020: Sharing Geoscience Online

4. Mai 2020
EGU has cancelled the physical General Assembly in Vienna for this spring and will instead host EGU2020: Sharing Geoscience Online (#shareEGU20).

From 4 to 8 May 2020 a series of online activities will help minimizing the impact of COVID-19 on scientific research and collaboration.

Many scientists from the Max Planck Institute for Biogeochemistry are co-organizing scientific sessions in various topics.
