In May 2022, the Geophysics Section conducted a field trip of several days to the North Sea island of Spiekeroog, as part of the course Hydrogeophysics in the Master's degree program in Physics of the Earth and Atmosphere. Spiekeroog is located off the North Sea coast of Lower Saxony, can be reached by ferry from the coastal town of Neuharlingersiel, and is part of the Wadden Sea National Park. The students learned the practical use of geophysical methods, e.g. electrical resistivity tomography (ERT) and ground penetrating radar (GPR), by investigating the freshwater-saltwater interfaces of the island’s groundwater and its tidal dynamics.
