Sea Ice Communities
Microorganisms living in sea ice affect carbon and nutrient cycling in polar seas, but their susceptibility to the changing environmental conditions of polar regions is not well understood. The Neuer lab has been studying the adaptation of sea ice organisms living immured in the brine channels of sea ice, using a model organism that was isolated from sea ice brine. In addition, we have been studying the microbial community structure of land-fast Arctic Sea Ice and how environmental variables, such as light and temperature, influence these sea ice communities.
