OCCR researchers featured in Greenland exhibition

Greenland exhibition

OCCR members Hubertus Fischer, Chantal Zeppenfeld (both Past Climate and Biogeochemical Studies on Ice Cores) and Thomas Stocker (Emeritus group Earth System Modelling – Climate Dynamics) are part of the exhibition "Greenland Everything Changes", which recently opened at the Alps Swiss Alpine Museum in Bern.

The three researchers are featured in the introductory part of the show, in which immersive projections serve as a counterpoint to some thirty filmed interviews with Greenlanders. A wide range of characters share their experiences and personal opinions about Greenland's intense, turbulent and contradictory transformation.

First meeting of the Advisory Board

The Advisory Board of the OCCR will hold its first meeting on 11 September 2025 in Bern. Various contacts with researchers are planned. The programme has not yet been finalised, but all OCCR members are asked to keep this date free for the time being. Further information will follow in February.

OCCR members continue drilling in Antarctica

drilling in Antarctica

The fourth campaign of the Beyond EPICA - Oldest Ice project has started in Antarctica. The aim is to retrieve a 2,750 metres deep ice core from the Antarctic ice sheet. In this crucial campaign, an international team aims to drill from the depth of 1,836 metres reached last season to 2,750 metres, where the bedrock is expected to be found.

Ice at this depth could contain records of the Earth's climate history going back up to 1.5 million years. OCCR members Lison Soussaintjean and Barbara Seth (both Past Climate and Biogeochemical Studies on Ice Cores group) are part of an international team of 16 scientists who will remain at the remote Little Dome C site until February 2025, with average summer temperatures of -35°C.

Writing for Publication in Climate Sciences

For several years, the Graduate School of Climate Sciences has offered a special writing course for our PhD students and Postdocs. The next course will start in February 2025. Our lecturer, Simon Milligan, one of the best in the field, will include sequences on using AI writing tools ethically and effectively, adapting texts to target audiences and journals, managing the writing process efficiently, structuring each section of the text optimally, producing fluent and reader-oriented sentences and paragraphs, editing the text before submission, and revising in response to reviewers' comments. More information and registration.

Funding for analysis of BeyondEPICA ice cores

Summerschool 2024

Hubertus Fischer (Past Climate and Biogeochemical Studies on Ice Cores group) has received funding (CHF 987,520) from the SNFS for his project CCC1.5 (Carbon Climate Coupling over the last 1.5 million years). The project aims to gain a deeper understanding of the Mid Pleistocene Transition (MPT), the period about 1 Myr ago when glacial cycles intensified and changed their cyclicity from about 40 kyr to 100 kyr. CCC1.5 will test hypotheses proposed to explain the MPT by obtaining unique direct atmospheric trace gas records from the first continuous ice core covering this enigmatic period, currently being drilled in Antarctica as part of the Beyond EPICA project (see above).

Science Night 2025

On Saturday 6 September 2025, the University of Bern will once again host a Science Night. This major event, aimed at the general public, offers researchers a unique opportunity to explain and publicise their work in an accessible way. As in previous editions of the event, the OCCR is considering a joint presentation with content from affiliated research groups. OCCR members with ideas for such a presentation should contact Communications Officer Kaspar Meuli (kaspar.meuli@unibe.ch). Proposals must be submitted to the University organisers by March.

ERC Consolidator Grant for Martin Hinz

Martin Hinz

Martin Hinz (Prehistoric Archaeology group) has been awarded an ERC Consolidator Grant for a project that aims to provide reliable and regionally differentiated estimates of prehistoric population dynamics in Europe and Western Asia from 12,000 to 2,000 years ago. Based at the Christian-Albrechts-University of Kiel, Germany, the project will use innovative statistical approaches such as hierarchical Bayesian modelling and data assimilation. By integrating archaeological and palaeo- ecological datasets, the project will address the limitations of outdated population estimates and provide new insights into the interactions between population dynamics, cultural innovation and environmental change.

SNSF Starting Grant for Franziska Lechleitner

Franziska Lechleitner

Franziska Lechleitner (Laboratory for the Analysis of Radiocarbon with AMS LARA) has been awarded an SNSF Starting Grant for her project "Refining terrestrial carbon export via observations of the deep Critical Zone (RESPIRE)". Based at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), the project will address critical knowledge gaps in understanding the export of carbon from terrestrial ecosystems to inland waters - an important but poorly constrained component of the global carbon cycle.

RESPIRE will focus on the complex and poorly understood processes governing carbon transport and transformation in the shallow subsurface, including deep soils and the unsaturated zone of aquifers.
