Figure Captions: (top) Process-based research based on the hypothesized response of carbon and water to permafrost degradation. Hypothesized responses are to be tested at increasingly larger spatial scales using both measurement and modeling techniques to understand changes in carbon, water, and energy in the Yukon River Basin. (lower left) Red colored Sphagnum Lenins covering shallow permafrost landscape (in background) was inundated upon thawing of the ice-rich permafrost, resulting in wetland ecosystems (bright green Sphagnum angustifolium in foreground) at Koyukuk Flats National Wildlife Refuge. (lower right) Wildfires in N-facing slopes of black spruce forests near Tok resulted in active layer thickening and drier soil conditions due to enhanced drainage. |
