2013 Carbon dioxide flux measurements at Cape Bounty, Nunavut

In 2013, eight ADC Automated Carbon Exchange (ACE) systems were deployed at the Cape Bounty Arctic Watershed Observatory (CBAWO) to quantify the contribution of the polar semi-desert vegetation type to landscape-scale NEE. As polar semi-desert vegetation cover varies at relatively small spatial scales, the chambers were distributed between vegetated areas (18-51% cover) and bare soil. Measurements were made every 30 minutes from late May to late July. Air temperature, soil temperature, and soil moisture measurements were collected in conjunction with NEE and ecosystem respiration (Re). In July 2013, Normalized Difference Vegetation Index (NDVI) data were collected to quantify variability in vegetation cover within the polar semi-desert. NDVI varied from -0.12 to 0.31, with the highest values occurring at vegetated sites and low values occurring on bare soil. Percent vegetation cover and NDVI correlated well at peak biomass (R2 = 0.96).
