 My research is about microalgae that live on the Greenlandic ice sheet and they produce dark pigments inside of their cells and due to these pigments they darken the ice surface in the areas where you find blooms of them and thereby they accelerate the ice melt and then I particularly was interested in how their pigments impact their darkening potential on the ice and also to what extent the nutrient availability and nutrient supply controls their growth. So we know very little about the natural biological processes of these remote regions like the Greenlandic ice sheet or in general about the Arctic and the cryosphere and yet these regions are strongly impacted by climate warming so that gives us a lot of time pressure to start finding out what are the natural processes that are occurring there before the impact that we have on these ecosystems is already so big here. For me being a researcher and especially in my field it's very special that we get to go to these remote places like the Greenlandic ice sheet and see this ecosystem with our own eyes and learn from it and also get surprised about how nature functions there and also to work together in a team because for doing this type of research you really need to work together in a team and collaborate also across different disciplines and by that then you can fit together the different pieces of information and see what we can find out and learn for a bigger picture. I hope that my research can help to fill some of the remaining big knowledge gaps that we have about the darkening of the Greenland ice sheet and also I hope that the research can be used to help to also communicate our scientific findings to the society and to the politicians for example to give them a little motivation to further invest in actually protecting these ecosystems and investing into slowing down and reducing greenhouse gas emissions.
