PI/DATA CONTACT = 	Jeffrey M. Welker
DATA COVERAGE = 	START: 19990726; STOP: 19990927 UTC
INSTRUMENT = 	LiCor LI-6200 portable photosynthesis system
LOCATION = 	Northwest coast of Greenland near Thule (76°31'N, 68°30'W).  Study sites include Polar desert, Polar semi-desert, Polar oasis, Polar desert deglaciated < 2years, Polar desert deglaciated ~50 years, Polar desert deglaciated >100 years
DATA VERSION = 	1.0, 28 February 2002, FINAL
REMARKS = 	Data are site, plot (replicate), temperature (C, each point is the mean of two measurements, net ecosystem CO2 exchange (umol m-2 s-1, each point is the mean of three measurements), plant and soil respiration (umol m-2 s-1, each point is the mean of three measurements), and gross photosynthesis (umol m-2 s-1, each point is the mean of three measurements).
REMARKS = 	See additional information in Jones, MH, JT Fahnestock, PD Stahl and JM Welker. 2000. A note on summer CO2 flux and soil microbial biomass from multiple high arctic ecosystems in northwestern Greenland. Arctic, Antarctic, and Alpine Research 32:104-106.
