Location

68° 39' 39.924" N, 149° 22' 13.692" W
Brief Site Description: 
Continuous permafrost, no trees, a complete snow for 7 to 9 months
Detailed Site Description: 

continuous permafrost, no trees, a complete snow cover for 7 to 9 months, winter ice cover on lakes, streams, and ocean, and cessation of river flow during the winter.

Arctic tundra—lakes, streams, tussock tundra, heath tundra, riverine willows.

Movement of nutrients from land to stream to lake; changes due to anthropogenic influences; controls of ecological processes by nutrients and by predation.
