Abteilung Geochemie/Petrologie

Die Abteilung Geochemie/Petrologie befasst sich mit der Geochemie und Petrologie der festen Erde, d. h. mit der materiellen Struktur der Erde, der Verteilung, Stabilität und dem Kreislauf chemischer Elemente und Isotopen in Mineralien, Steinen und wässrigen Lösungen. Der Fokus der Forschungsprojekte der Abteilung liegen derzeit im Bereich der Vulkanologie, Geochronologie, metamorphen Petrologie und Strukturgeologie und der Interaktion zwischen Feststoffen und wässrigen Lösungen sowie in Bereichen der technischen und angewandten Mineralogie.

Anfang 2024 führt die Abt. Geophysik mit Projektpartnern von UNIS u. FZ Jülich Messungen auf Svalbard durch

Von Mitte Februar bis Mitte März 2024 führt ein Team der Bonner Abteilung Geophysik in Zusammenarbeit mit Projektpartnern des University Centre in Svalbard (UNIS) und des Forschungszentrums Jülich geophysikalische Messungen auf Svalbard durch. Das Team bildet den Untergrund mit verschiedenen geophysikalischen Methoden ab, um das Verständnis der Grundwasserströmungswege zu verbessern, die zu Oberflächenvereisungen in Gletschervorfeldern sowie an küstennahen Pingos führen, wo Methanausgasungen auftreten.

PrePEP conference 2025

The international conference on ‘Precipitation Processes - Estimation and Prediction (PrePEP)’ to be held 17-21 March 2025 in Bonn, Germany, will bring together scientists contributing with new approaches to improve the monitoring, understanding, nowcasting and prediction of precipitation processes. This includes advancements in integrated multi-sensor observations, their exploitation for parameterization developments, classical or AI-based Nowcasting techniques, microphysical retrieval development, data assimilation, the blending with numerical weather prediction, hydrological flood forecasts and warning strategies. Please visit the conference website https://indico.scc.kit.edu/event/prepep/ for more information. Looking forward to seeing you in Bonn!

Wissenschaftsrallye rund um Poppelsdorf

Am 27.01. haben wir mit zwei Stationen an der Wissenschaftsrallye rund um Poppelsdorf teilgenommen. Unter strahlendem Sonnenschein besuchten über 300 Schülerinnen verschiedene  wissenschaftliche Stationen. An unseren Stationen konnten die Schüler*innen Neues über Wetter und Klima erfahren. Neben Erläuterungen zu den Themen und Messmethoden hatten sie die  Möglichkeit, das Gelernte durch Experimente zu veranschaulichen.
