Narrator: This is Science Today. Due to climate change, the Arctic landscape is undergoing a period of rapid transformation. Permafrost covers much of the terrain, and alterations to its pattern of seasonal thaws and freezes are of great concern to scientists. Now, a team of researchers is working to provide a coherent picture of why these changes are happening and what it means for the future. Geologist Susan Hubbard of the Lawrence Berkeley National Laboratory says the 10-year project, called the Next Generation Ecosystem Experiment is looking at a variety of things.
Hubbard: The hydrology, the biogeochemistry, vegetation dynamics, soil microbial ecology, the geomorphology and its interconnectedness and then the scale aspect.
Narrator: The large, multidisciplinary team project will also look at processes from the molecular all the way up to the global scale.
Hubbard: So it's really trying to cover this whole range of things that we think are important not only for understanding this system but predicting how that system's going to change with warming.
