Water isotope group
Investigating past climatic conditions using water stable isotopes
The water stable isotope measured in Greenland ice cores can be used to estimate key meteorological parameters such as temperatures and accumulation rates on the Greenland ice sheet back in time. The water isotopes are even a key component, when we model how the ice sheet is moving near an ice core drill site.
Hence, the water isotope record is a cornerstone of ice core glaciology, and if you are interested in helping us understand the climate of the past in Greenland, then we can always develop project ideas taking a modelling approach on existing ice core data, and often offer projects that also includes a significant measuring component, where you will be expected to carry out new ice core sampling and measurements in the water isotope lab.
It is also possible to look deeper into the meteorology driving the water isotope signal we see in our cores together with colleagues with a meteorology background both here at NBI and at DMI.

Modelling the termination of the last Ice Age in Greenland with the Community Firn Model
Are you looking for an exciting Msc thesis project where you can combine your Python computational skills with inverse methods and state of the art datasets of N2 and Ar isotopes in order to look far back in Greenland's past climate? If you are fascinated by polar research and curious about climate change processes this may be a unique chance for you to join a dynamic group with decades of history in polar and ice core research.
You will be looking into the abrupt warming signals during the sudden end of the last Ice Age about 12,000 ago and using a state-of-the-art model of snow densification and gas diffusion you will work towards quantifying the magnitude and rapidity of the abrupt climate change during this time. We require that you are familiar with Python and you can expect your skills to get very sharp during the duration of the project. You will get hands-on experience with polar snow/firn modelling tools and high quality datasets of N2 and Ar isotopes from the air bubbles in the ancient ice. We are a very open and dynamic group with a variety of nationalities and backgrounds as well as a wide international network of collaborations.
