Coldregionscience was originally set up as a website describing my research and teaching in the High Arctic and Antarctica.
With time it developed organically, and now you will also find here usueful information on both Polar Regions, interesting resurces for research, teaching or exploration, polar environmental reports or window into the Arctic and Antarctica via webcams. 
Coldregionscience focuses on the influence of changing climate on hydrology (e.g. runoff, water balance), biogeochemistry, and microbial activity within the snow and ice.

Dr Aga Nowak

I am an interdisciplinary environmental scientist specialising in freshwater runoff 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 High Arctic and Antarctica. Read more..

Currently, I am the researcher on the BIOICE project investigatigating Blue Ice Oases of microbial life on the Antarctic Ice Sheet. 

I am also 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..
