Against the backdrop of the Lacandon rainforest, Southern Mexico, with its impressive vegetation and exotic animals, seven students had the opportunity to investigate tropical lakes ecologically and geophysically. Along the way, they gained insights into the life of the Lacandons, who belong to the Mayan ethnic group, and were able to taste local culinary specialties. In the magazine of the TU Braunschweig, physics students Bastian Brömer and Ruth Glebe report about the trip - organized by Liseth Pérez from the Institute for Geosystems and Bioindication and Matthias Bücker from the IGEP.
