Coldregionscience is a website describing my research in the High Arctic and Antarctica. I focus on the influence of changing climate on hydrology, biogeochemistry, and microbial activity within the snow and ice.

Dr Aga Nowak


I am an environmental scientist specialising in hydrology and biogeochemistry. 

My research focuses on investigation of short- as well as long-term effects of climate change on the terrestrial and marine ecosystems, with the focus on the Arctic and Antarctica. Read more..

Currently, I have a split position at the University Centre in Svalbard (UNIS).


Therefore, I am the researcher on the BIOICE project, where we investigate Blue Ice Oases of microbial life on the Antarctic Ice Sheet. 

I am also an Adjunct Associate Professor in Hydrology.

As with research, I am passionate about teaching, as I believe students are our future. Thus, I always strive to provide the highest quality of learning environment for my students using inquiry-based learning. Read more..
