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.

Nature’s Fireworks

This glorious photo of the sunset was taken the night of July 4th, near the harbor and downtown Reykjavik. The photo barely captures the beauty we observed with our own eyes. While we are rarely up to see midnight sun set here in Iceland during the summer, we were excited to see that nature provided us with fireworks more extravagant than anything we have ever seen before! It was quite a sight for us to see, especially since our families back in the U.S. were celebrating Independence Day. Iceland - thank you for the spectacular show!
