TEON: Terrestrial Environmental Observation Network The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

In this study, researchers are addressing this knowledge gap by adopting a space-for-time approach. Fish and food web ecology, and mercury accumulation patterns, are being investigated in several lakes that represent a gradient in temperature/ice phenology of up to two ice-free weeks and 10°C. They are also comparing food web structure and rates of mercury biomagnification among the lakes, and relating these to several climate variables. Finally, they are relating past trends in mercury accumulation in lake sediments to indices of lake productivity...
