ESM at vEGU General Assembly 2021

This year’s virtual conference of the European Geoscience Union (EGU) will take place during 19-30 April 2021. The 2021 conference offers a well-organized forum for scientists to present their research and interact with experts in all fields of geoscience. More information and the full Program are available at
