The "IGeo" represents an interface between basic and applied research. We are interested in natural climate variability as well as climate and human impact on aquatic ecosystems in both urban and remote, near-natural regions.
Our core areas in research and teaching are based on geoscientific, limnological, ecological and sediment-geological methods, GIS-based landscape reconstructions, and bioindication, the analysis and application of organisms as environmental and climate indicators. We use sediments as environmental archives for long-term monitoring of aquatic ecosystem dynamics.
We train our students in geo-ecosystem understanding so that they are well prepared to assess interdependencies and feedbacks within and outside the geo-ecosystem. Students are qualified for employments in the fields of landscape management, water quality assessment, conservation, (paleo-) climate research and able to develop concepts for environmental protection, especially under the aspects of future climate development and landuse, or to collaborate in international and interdisciplinary research programs.
June 30th, 2026 – “Traces of industry in Asia’s water tower” - A study by an international research team led by the Technical University of Braunschweig has now shown that greenhouse gas emissions and industrial air pollution have significantly altered the sensitive ecosystem of the lakes over the past millennium. As part of their research, the scientists analysed sediments from Lake Nam Co, amongst other sources. The findings have now been published in the journal *Nature Communications*. – Press release from the TU Braunschweig (link)
