Physics of Ice, Climate and Earth
The section for the Physics of Ice, Climate and Earth at the Niels Bohr Institute studies the elements of the Earth and climate system – the atmosphere, oceans, ice sheets and glaciers, sea ice, and the solid Earth itself – and the interactions between them.
At the Niels Bohr Institute's section for the Physics of Ice, Climate and Earth, we are world leaders in drilling deep ice cores from the Greenland and Antarctic ice sheets. We analyse the ice samples in our laboratories and study water stable isotopes, greenhouse gas, impurity concentrations, and ice properties. We interpret the data together with results from computer models of all parts of the climate system, including general circulation models and models of ice flow. We also work with theoretical aspects of meteorology, oceanography and complex system dynamics to understand both gradual and abrupt climatic changes of the past, present, and future. We study the physics of the solid Earth with seismic data, gravity and magnetic observations from satellites, inverse method theory and numerical modelling.
The Niels Bohr Institute’s section for the Physics of Ice, Climate and Earth (PICE) was created in 2019 by merging the former sections for Ice and Climate and Climate and Computational Geophysics. It includes the Centre for Ice and Climate which encompasses the section's research in ice-core-related climate physics. Centre for Ice and Climate builds on a long tradition that goes back to the birth of ice-core palaeoclimatology. The Centre for Ice and Climate home page contains extensive data and publication collections within ice and climate research. During the period 2007-2017 the center was funded by the Danish National Research Foundation.
The research in the section for Ice, Climate and Earth deals with all elements of the climate system and the processes and feedbacks that connect them.
We perform field work to obtain samples and data and employ a combination of state-of-the-art measurements, computational methods, and novel theoretical approaches to improve our knowledge of past, present, and future climate. Choose a topic below to learn more.
Ice and Climate
We study the ice caps and the climate by drilling and analysing ice cores from Arctic and Antarctica. We investigate the physical properties of ice on all scales from the individual crystals to the entire ice sheet. We analyse greenhouse gasses and impurities caught in the ice to understand the climate of the past, present, and future. Our research combines field work and glaciology with computer modelling, laboratory work, and mathematical data analysis.
The Climate Theory group is engaged in understanding the Earth's climate. The surface temperature on the planet depends on solar radiation, composition of the atmosphere, heat flow in the atmosphere and oceans, ice masses and many other factors. Further, fundamental research in turbulence, multi scale processes, bifurcation theory, critical transitions and complex systems is conducted.
Weather and Climate
We study and develop models of the physical processes of the atmosphere, e.g. for numerical weather prediction. Other topics are air quality and pollution.
Ocean Dynamics and the Carbon Cycle
The research is focused on ocean processes that contribute to water mass transformations and the large climate fluctuations observed in the last million years.
Solid Earth Physics and Computational Geoscience
We study the solid Earth using field experiments, theory and numerical modelling based on seismic data and satellite measurements of gravity and magnetism.

Bachelor or master thesis projects at PICE
You can find a list with inspiration/suggestion for projects here: student projects at PICE.
A list of theses and dissertations from previous students is also available.
Do your bachelor or master thesis project at the section for Physics of Ice, Climate and Earth. As a bachelor or master student at the section, you will work in active and dynamic groups on a real research project. We offer both 30 or 60 ECTS points projects.
You are also very welcome to come by the section and ask the researchers for further options or present your own idea that we can develop together. You are also welcome to contact the section for hear more about options for doing your project at the section.
It is at the moment not possible to visit the section due to the conora virus situation in Denmark.
Web pages, movies, popular science papers about our research
Under Research you will find A lot of the section’s ice-core-based climate research described for non-specialists. You can also find information about our available high-school projects “studieretningsprojekter”. Finally, we provide a list of popular science texts in Danish.
Willi Dansgaard founded the world’s first research group focused on climate research based on ice-core analysis (read a short version of the background story here).
After his retirement in 1992, Willi Dansgaard wrote an autobiograhic book in Danish, Grønland i Istid og Nutid (Rhodos, 2000, ISBN 8772457996). Later, he compiled an English version, Frozen Annals, which focuses more on the scientific part of the story. The book can be downloaded here as a pdf file.
