Since 2006, the German Geopyhsical Society (DGG) promotes the C.F. Gauss Lecture within the frame of the General Assembly of the European Geosciences Union (EGU). Selected authors give an in-depth overview on a specific field of geophysics. The C.F. Gauss Lecture will be accompanied by a reception for members and friends of the DGG before it starts. All delegates of the EGU2014 are invited to participate.
