Summary: Check soil co2 gradient system, 6400 soil co2 respiration

Trip note On June 25, 2003 (d176)
Who: Jianwu Tang and Qi Chen
Weather; Sunny, air temperature as high as 40-45oC

The electronic fences work well. We measured soil CO2 efflux along the transect and check the soil CO2 profile measurements, and measure tree respiration.

CO2 efflux averaged 2 mmol m-2 s-1 under trees, while 0.5 mmol m-2 s-1 in the open areas. The average soil profile is 1600PPM (2cm), 6000ppm (8cm), and 9000ppm (16cm) under trees, and 380PPM (2cm), 1000ppm (8cm), and 2000ppm (16cm) in the open area. The average of tree respiration is 2.5 mmol m-2 s-1.
