This video shows landscapes of Alaska. From glaciers in the Alaska Range, to the Interior's boreal forest and the Arctic tundra--this short movie highlights the importance and stunning beauty of Alaska's frozen lands. It contains footage taken by Alessio Gusmeroli during research expeditions to the study glaciers, snow and permafrost in Alaska. The soundtrack for this movie is "Arktika" by the Russian artist Mara, who kindly gave permission to use this song for research and education. It fits perfectly with the landscapes shown in the video.

The Boreal System illustration depicts some of the landscape characteristics, changes and drivers of change in the boreal ecosystem prevalent throughout Alaska and Northwest Canada. This illustration was developed as part of the Integrated Ecosystem Model project supported by the AK CASC.

The vector illustration can be used as a PDF or opened and edited using Adobe Illustrator.

"Modeling Thermokarst Dynamics in Alaska Ecosystems" was a poster presented at the American Geophysical Union Fall 2012 Meeting in San Francisco, California. The poster authors include Yujin Zhang, A. David McGuire, Helene Genet, Bob Bolton, Vladimir Romanovsky, Guido Grosse, and Torre Jorgenson.

Boreal wetlands are important for wildlife and carbon storage and are being affected by multiple environmental stressors including permafrost thaw. In particular, thermokarst bogs resulting from permafrost thaw can result in large feedbacks to global climate if methane (CH4) and carbon dioxide (CO2) fluxes are large. In addition, our understanding of the environmental, chemical, and biotic interactions that control greenhouse gas fluxes from thawing permafrost environments is limited, and changes over the course of wetland development.
