Thule Biocomplexity - Gross Ecosystem Photosynthesis

Ecosystem carbon dioxide flux measurements were taken at a High Arctic prostrate dwarf-shrub, herb tundra near Pituffik (Thule), Greenland (76 deg 29'N, 68 deg 26'W; elevation 245 m asl) northwest Greenland. Between 1978 and 2004, mean annual air temperature and precipitation for the site were -11.4 deg C and 12.5 cm respectively. Over the same period, growing season (June, July and August) air temperatures averaged 3.8 deg C and approximately 50% of precipitation fell between October and April as snow. The soil surface of the study site was approximately 40% covered by vascular plants and 60% unvegetated. Dominant vascular plants include the deciduous dwarf-shrub Salix arctica, the graminoid Carex rupestris and the wintergreen dwarf-shrub Dryas integrifolia. The dataset covers the growing seasons of 2006 and 2007.
