Large Area Estimates of Carbon Fluxes of Arctic Landscapes

Net CO2, evapotranspiration, and energy exchange were measured during 1998-2001 in wet-moist coastal sedge tundra (Barrow: 71 degrees 21 minutes north, 156 degrees 37 minutes west) and moist-wet coastal sedge tundra/moist-tussock tundra ecosystems (Atqasuk: 70 degrees 28 minutes north, 157 degrees 25 minutes west), and during the 1994-95 growing seasons (June-August) in moist-acidic (Happy Valley: 69 degrees 9 minutes north, 148 degrees 51 minutes west), moist non-acidic (24-Mile: 69 degrees 56 minutes north, 148 degrees 49 minutes west) and wet-sedge tundra ecosystems (U-Pad: 70 degrees 17 minutes north, 148 degrees 53 minutes west) located on the north slope of Alaska.
