The Fixation on Ice crew has been back in the United States for almost two months now! Time sure flies! Sample analysis in the laboratory is in full swing, and we have been working on some video production to help visually accentuate our experience! Below is a synopsis of our summer in Iceland in just over five minutes. Take a journey to Iceland with us as we collect samples, explore the country, and have the best time of our lives! Stay tuned for further videos that will include audio from team members.
We are a group of freshwater ecologists from the Biology Department at St. Catherine University in Saint Paul, Minnesota. Our research takes us to Iceland and other arctic regions where we are working to understand how temperature influences nitrogen fixation rates and metabolism in cyanobacterial assemblages. Nitrogen fixation is extremely sensitive to temperature and therefore nitrogen gas from the atmosphere may become more accessible to freshwater ecosystems as the climate warms. We are working to understand the potential ecological and environmental implications of changes in cyanobacteria species composition and nitrogen fixation rates in arctic lakes and streams.
