The OCCR’s Laboratory for the Analysis of Radiocarbon with AMS (LARA) and its Quaternary Geology and Paleoclimatology group are part of an interdisciplinary research project that was initiated by the Archeological Survey of the Canton of Thurgau.
The project was started in 2015, after a Neolithic structure with over 170 mounds was detected in Lake Constance by a high-resolution bathymetric survey.
This finding triggered large interest in many disciplines as well as public debates. In order to determine the age of the discovered mounds, the OCCR team recovered a series of up to 6 m deep drill cores. They provide a sedimentologic archive, spanning from the last glaciation 18'000 years ago to today. The sedimentology, stratigraphy and paleoenvironmental significance of these cores are now beeing investigated. A first radiocarbon analysis has revealed an age of the mounds of approximately 5'500 years before present, placing them in the Neolithic epoch. Future investigations will refine the knowledge of origin and purpose of this aligned mounds that form one of the largest Neolithic structures worldwide.

The University of Bern has decided to join a new initiative called International Universities Climate Change Consortium (IUC3) that was launched by the University of New South Wales, Sydney. IUC3 intends to form a group of around 50 leading universities, representing all regions of the world, to provide a strong and respected international voice on matters related to climate change science, impacts, mitigation and adaptation. The future role of IUC3 should be to engage with policymakers on international climate agreements, analyse reports and statements to synthesise and disseminate the latest science, and deliver clear communications on carbon mitigation, renewables, local and international climate solutions and climate change adaptation.
On a regular basis, the management of the OCCR meets the University Board of Directors for strategy talks. The outcome of these recent talks was very positive – according to the Board, the OCCR has met all its goals, which are included in its performance mandate, and it continuously makes progresses in its performance.
The leading German news magazine Der Spiegel reports on EXPLO (Exploring the dynamics and causes of prehistoric land use change in the cradle of European farming) in its online edition. The magazine covers field work on Lake Ohrid in North Macedonia in a long read as well as in a video. EXPLO is an interdisciplinary project initiated by Alfred Hafner (Prehistory Archeology group) and Willy Tinner (Palaeoecology group). It was awarded an “ERC Synergy Grant” and is supported by the EU with €6.4 million.
Karin Ingold (Policy Analysis and Environmental Governance group) has been granted SNFS funding for a project entitled “Same, same but different? Multiplex networks in Swiss and German Climate Mitigation Policy. ”The project will finance a PostDoc position over the next three years and a Ph.D. position over the next four years. The research proposal reads: ”The first contribution of this project is to evaluate the conditions under which actors involved in climate policymaking start coordinating their actions. The second contribution is of practical relevance. Climate policymaking is rather an example of policy failure than of policy success. This holds true already for the policy design, when only second-best options can gain enough support by the political elite. We give more evidence about how a joint problem understanding or how bringing diverse stakeholders around one table might enhance climate policy coordination at the domestic level“.
The Mobiliar Lab for Natural Risks has just published the latest issue of its biannual newsletter (in German). Topics featured include: new approach to heavy precipitations scenarios, climate change and flood protection and how to combine global climate models and damages functions for single houses.
The LARA radiocarbon dating laboratory at OCCR is a leading tool when it comes to analysing small material samples. This know-how was also in demand for dating the bronze hand of Prêles, a find that has made international headlines. The laboratory is equipped with highly specialised technology that makes it possible to carry out 14C age determinations using even tiny material samples. For example, when OCCR researchers need age data about the individual layers of lake sediments used as climate and environmental archives, samples of just a few milligrams – or sometimes even smaller – must suffice. In the case of the Prêles find, the 14C laboratory also dated bone finds – a big challenge from a methodological and technical point of view. Over the last years, LARA has refined a method that uses ultrafiltration to prepare bone samples.

Andreas Zischg (Mobiliar Group for Climate Impact Research) has been promoted to Assistant Professor (non-tenure-track).
Christoph Schwörer (Palaeoecology group) is building up his own research group on Paleoecology - Population Dynamics. He is able to do so thanks to an SNFS grant of CHF 443’000 he has been awarded for a project called “Tracking Holocene genetic diversity of Swiss mountain forests using ancient DNA”. Earlier this year, he had already been awarded a substantial grant by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). The project summary of his new project reads: “To study past climate-driven range shifts and their effects on genetic diversity and the adaptive potential of trees, I propose a novel, holistic approach that combines established palaeoecological methods with the analysis of ancient DNA (aDNA) and dynamic vegetation modelling.”
Thomas Frölicher (Ocean Modelling group) was awarded the Theodor Kocher Prize by the University of Bern. The prize, which is an award of CHF 50,000, is conferred on young researchers at the University of Bern for outstanding and innovative scientific achievement in any faculty or field. It is traditionally handed over at the University of Bern’s Dies academicus which took place on 7 December.
Michael Sigl (Past Volcanism and Climate Impact group) was interviewed for the education website Royal Society of Chemistry (“We support teachers to inspire future generations of scientists around the world article”). The article "Frozen in time", in which Michael is quoted, shows the lengths scientists go to for their research and was specially written for students. The note for teachers reads: “Environmental issues including climate change now have a high profile in the mainstream media, presenting students with a wide range of commentary and opinion. This should make atmospheric chemistry an easy subject to teach, yet it can seem dry and theoretical when presented in the curriculum context. This article helps students to see how scientists are collecting data that is providing evidence for atmospheric changes in the past, a long time before scientific records began.”
Caroline Heitz (Prehistory Archeology group) has been rewarded for her PhD-thesis by the Faculty of Humanities of the University of Bern. She won the thesis of the year award of 10’000 CHF. Her work is part of the SNFS project “Mobilities, entanglements and transformations in Neolithic societies on the Swiss Plateau (3900-3500 BC)”.
