AB: The Beringia project is based on a novel rapid assessment technique to quantify decadal scale change in radiative forcing potential in the Beringia region. During the 2005-2007 summer seasons, 16 sites throughout the Beringia region were visited. Sites locations included Chukotka, Wrangel Island, the North Slope of Alaska, and the Seward Peninsula. Study plots of different land cover types were chosen for the purpose of determining their radiative forcing potential based on trace gas exchange (CO2, CH4) potential and albedo. This report examines the relationship of trace gas exchange (CO2 and CH4), hyperspectral reflectance, soil moisture, species cover, leaf area index (LAI), active layer depth, and above-ground plant biomass for different land cover types. The data presented are analyses from three years of data collection.
