Le jeudi 7 décembre à 10:30, en salle Bernard Auvray (RDC bât. 15), Peter Bayer propose un séminaire intitulé "Heated foundations and climate change below: Exploring thermal footprints in shallow groundwater"

Abstract:
Shallow aquifers are sluggish systems in comparison to the connected atmospheric environment. They act like batteries that memorize thermal variations induced from above. We observe delayed thermal responses to global climate change in measured long-term time series of groundwater temperatures. Strongest thermal anomalies are found beneath cities, where the combined effect of multiple factors induces evolving subsurface urban heat islands. This presentation reveals spatial and temporal trends observed in Germany and Switzerland. Utilizing measurements from groundwater, land-surface and air temperature, thermal coupling is studied through correlation analysis and analytical simulation.
