A number of members from the DFG Priority Programme “Tropical Climate Variability & Coral Reefs” (SPP 2299) attended the annual European Geosciences Union (EGU) General Assembly of 2023 in April. The EGU General Assembly 2023 brought together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The SPP 2299 members, Jessica Hargreaves (MARUM, University of Bremen), Thomas Felis (MARUM, University of Bremen), Sophie Warken (Heidelberg University) and Andrew Dolman (AWI Potsdam) all presented posters across a number of different sessions during the conference and on different topics, demonstrating the variety of expertise of researchers involved in SPP 2299. This was the first opportunity for the SPP 2299 to be presented at an in-person international conference. The poster (seen in the image, or to the right) represented the 19 projects within the programme from all across Germany (with a map representing each of our participating institutions). The projects were represented with a short highlight, displaying some of the excellent science across our programme.
The EGU23 General Assembly welcomed 18,831 registered attendees, of which 15,453 made their way to Vienna from 107 countries and 3,378 joined online from 105 countries. Each of the SPP 2299 member (highlighted in bold) abstracts can be found here;
