Do you want to help uncover how meltwater moves beneath the Greenland Ice Sheet, and how this affects ice flow and sediment transport? GEUS' Department of Glaciology and Climate is offering a 3-year PhD position starting 1st January 2027, based in our Copenhagen office, as part of the REGLA project.
About the position
This PhD project investigates how meltwater moves through and beneath the Greenland Ice Sheet, and how this shapes both ice flow and sediment transport to the ocean. Using satellite radar interferometry, you will map subglacial water routes and how they evolve over time, then apply machine learning methods to explore how meltwater — at the surface and at the ice sheet bed — is coupled to ice flow. Building on this, you will also examine how meltwater and ice dynamics influence sediment output from glaciers, combining new remote-sensing and in-situ datasets.
The position is part of Prof. Nanna B. Karlsson’s REGLA project, who will be your main supervisor. You will be co-supervised by Prof. Louise S. Sørensen and Anders Kusk from DTU-Space and also work in close collaboration with Anne Solgaard (GEUS) and REGLA project team members. You will be based at GEUS' Department of Glaciology and Climate, and enrolled as a PhD student at DTU-Space, the Technical University of Denmark.
Who are you?
You have, or are about to complete, a master's degree within geoscience, physics, geophysics, engineering, or a related field. We imagine you are interested in remote sensing, glaciology, and/or data-driven methods such as machine learning, and that you are motivated to develop these skills further during your PhD. We expect that you are curious about glaciology, ice sheet processes and/or satellite remote sensing and motivated to learn or further develop programming and data analysis skills (e.g. Python, machine learning methods). We are looking for a person who can work independently but also thrive in a collaborative project team.
It is an advantage, but not a requirement, that you have prior experience with machine learning, satellite remote sensing (e.g. InSAR/DInSAR), or one or more programming languages. Insights into glaciological topics are also an advantage but not a requirement.
You must be able to communicate in English, and since Danish is GEUS’s primary language, you should be prepared to attend Danish language lessons if you do not speak Danish.
Meet your new colleagues
You will join the Department of Glaciology and Climate at GEUS. Our department studies current and past changes in the Greenland Ice Sheet and the surrounding ocean, with one of our main activities being long-term monitoring of the ice sheet through programmes such as PROMICE and the Greenland Climate Network (GC-Net). In addition to conducting research, we advise government agencies and the private sector and supervise university students.
The department has an international staff of researchers, PhD students and postdoctoral fellows working across topics such as ice dynamics, glacier hydrology, remote sensing and climate monitoring. We have a strong focus on multi-disciplinary collaboration across the department and hold regular seminars and other activities to foster this. We also prioritise social arrangements to welcome and integrate new employees into our informal and friendly working environment.
You will be enrolled at the DTU Space PhD student program and become part of the PhD community there. Read more about the PhD education at DTU Space here: https://www.space.dtu.dk/english/phd-education
A working environment with a focus on professional development and well-being
There are many good reasons why you should choose a working life at GEUS.
We are a diverse staff of about 300 committed employees. Trust and flexibility are keywords. The working environment is lively, informal and international. Our tasks are versatile and there are plenty of opportunities for you to influence the development of your task portfolio.
We prioritise professional development, among other things, by offering access to courses and other relevant activities. Socialising is also very important at GEUS, and we have a rich social life with a staff club, an art association and a gym with associated physiotherapists..
At GEUS, we prioritise the well-being of every single employee. We prioritise that the Heads of Departments are close to the employees, and we have flexible working hours that allow you to organise your life so that there is time for what matters to you. If you need to work from home occasionally, that is also possible.
