Besides being part of METALLICA, Silje is also a doctoral candidate of the MSCA Doctoral Network ICEBIO, which aims to investigate the biogeochemistry and microbiology related to glaciers (MSCA DN 1072761: ICEBIO - Center for Glacial Biome Doctoral Network). Silje’s work revolves around how rock flour generated by glaciers interacts with marine biogeochemical and microbiological cycles. Depending on the parent rock composition, the glacial rock flour can contain both nutrients and trace metals essential, but also potentially harmful to marine organisms. She shares updates on her fieldwork and life as a PhD student in Tromsø primarily through Instagram as @SiljeWaaler.

The aim of the blog is to get you, the reader, excited about all things related to ice, whether it be the tiniest ice crystals, snow drifts, beautiful mountain glaciers or the vast polar ice sheets. Here, the latest fieldwork programmes, research projects or scientific results will be showcased by bloggers from the cryospheric community. The blog is currently run by Loeka Jongejans, Lina Madaj and Maria Scheel. Would you like to write a blog entry about your research?
