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... download: NSF Arctic Data Center	ARCSS	Welker, J. Schimel, J. Sletten, R.	1.0 2008-11-13
Thule Fen CO2 Exchange 2004-2006 This dataset includes mid-day measurements of CO2 exchange in hummocks and pools with and without open-top experimental warming chambers (OTCs). Measurements were made using a LI-6200 and a clear acrylic 20 x 20 x 20 cm chamber over a 30 second period... download: NSF Arctic Data Center	ARCSS	Welker, J. Sullivan, P.	1.0 2008-11-13
Toolik Dry Tundra Ecosystem Flux [Welker, J., J. Fahnestock] This dataset represents four growing seasons (1996, 1997, 1998, 2000) of ecosystem (plant + soil) respiration data from moist acidic tussock and dry heath tundra to the atmosphere. The data is column delimited ASCII format. For more information, see... ORDER	ITEX ATLAS	Welker, J. Fahnestock, J.	1.0 2007-11-02
Toolik Litter Study [Welker, J., J. Fahnestock] The data set presented here represents part of a study that examined the ecological consequences of allochthonous litter deposition in tundra communities near Toolik Lake, Alaska. The study indicates that wintertime litter redistribution is an... ORDER	ITEX ATLAS	Welker, J. Fahnestock, J.	1.0 2007-11-02
Toolik Moist Tundra Ecosystem Flux [Welker, J., J. Fahnestock] This dataset represents four growing seasons (1996, 1997, 1998, 2000) of net carbon dioxide exchange between the moist acidic tussock tundra, dry heath tundra, and the atmosphere. The data is column delimited ASCII format. For more information, see the... ORDER	ITEX ATLAS	Welker, J. Fahnestock, J.	1.0 2007-11-02
Winter CO2 efflux - IRGA [Welker, J., J. Fahnestock] This dataset contains estimates of wintertime carbon efflux from various tundra and subarctic soils over several winters in Barrow, Alaska, Toolik Lake, Alaska and other Alaskan sites. Data is in .txt format. ORDER	ATLAS	Welker, J. Fahnestock, J.	1.0 2007-11-05
