Toolik Field Station on Alaska's North Slope offers scientists a prime location to study how climate change is impacting Arctic ecosystems
A North Slope "fish spa" might hold answers to how arctic grayling will react in a changing climate.
Researchers are testing whether some populations of arctic grayling are better suited than others to the changing climate.
North Slope lakes get artificial warmth to simulate climate change.
Using swimming pool heaters and generators, scientists are hoping to see how fish and smaller organisms will react as the region warms.
