About Me

I am a climate physicist and oceanographer specializing in high-latitude climate dynamics and atmosphere-ocean-ice interactions. With a PhD from the Alfred-Wegener-Institute for Polar and Marine Science, my current work at the Alfred-Wegener-Institute focusses on understanding Southern Ocean sea ice variability and model-observation mismatches. I am particularly interested in the yet underrepresented role of ocean-cryosphere interactions, such as cavities and icebergs and their impact on the Southern Ocean. I have extensive experience in applying state-of-the-art ocean and climate models, in particular the Alfred-Wegner-Institute Climate Model and the Finite Volume Ocean and Sea Ice Model FESOM2.1, with strong programming skills in Python, MATLAB, and Fortran90. My research is documented in high-impact journals, and I thrive in interdisciplinary collaborations to address pressing climate challenges. Passionate about advancing Earth system modeling, I also enjoy sharing scientific insights through teaching, outreach, and engaging with diverse audiences.

Research Spotlight

Heukamp et al. 2025 | Nature Communications

Over the past 50 years, Arctic sea ice has declined in all seasons, with particularly pronounced winter reductions in the Barents Sea. While temperature changes in the Atlantic Water inflow and atmospheric-driven melt have been identified as key drivers of this decline, the role of the return-flow of Atlantic Water in the northern Barents Sea Opening, linked to its recirculation back into the Nordic Seas, has remained largely unrecognized. Using a global ocean and sea ice model, we find that the volume transport of the Atlantic Water return-flow is strongly correlated with the sea ice area in the Barents Sea. In addition, we find that, over the past 40 years, the return-flow has steadily weakened without a corresponding change in inflow. Here, we show that reduced Atlantic Water removal by a weakened return-flow contributes to both interannual variability and the sustained loss of Barents Sea sea ice.
