Author: Siyan Ma

Summary: Swapped tank and measured water potential, standard field work.


When: Date: 7/4/2012 , Day: 186 , Watch Time: 5:20am
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: clear, sunny
Phenology: dead grasses looked bright yellow under the sun; green oak leaves, likely less leaves; the third layers of single pine shoots showed yellow needles.



Summary
  1. Swapped the tank and measured water potential of oak leaves and pine needles at watch time 5:30, 8:30, 13:00, and 14:00. The lowest water potential occurred at 8:30, which is interesting to me.
  2. Checked and downloaded data at Tower, Floor, and Vaira successfully
  3. Calibrated Li-800 in the field. The CO2 profile system worked well.
  4. Tram system was working.
  5. Pyronometer at Vaira had water inside the cover (see the photo above)
  6. Checked soil CO2 profile systems at both sites.
  7. Read dendrometers
  8. Measured soil moisture
  9. Measured groundwater well:

Vaira_Grass Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

  1. downloading data YES!
  2. Check the fans of air temp. and relative humidity sensors at Vaira. YES!
  3. Check MD-9 system connections YES!
  4. Check CR23X with two multiplexers

  1. Download data from soil CO2 profiles: first I had trouble to talk to the CR10X datalogger with the cables I brought from the lab; then I tried talking to it with the cables that Joe installed in the computer enclosure, and changed the COM Port to #5, and then it worked for me.
  2. Check levels of Radiation sensors, clear up surfaces. YES!
  3. Check rain gage, make sure not clogged. YES!
  4. Closed gate and set up fence. YES!

Tonzi_Tower Site

  1. Fence and gate power: 12 v.
  2. Panel and Batteries: 12.5 v; 0.7 amps; 2.8 amps. (I read these values around 7:00am and tried downloading data, but the computer restarted itself.)
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

  1. downloading data YES!
  2. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
  3. Check rain gage, make sure not clogged. YES!
  4. Check calibration cylinders;

CO2 1100 psig; flow 20 psi; 421.63 ppm.
N2 1500 psig; flow 20 psi.
Is the pump running‌ YES!
  1. Check levels of Radiation sensors, clear up surfaces. YES!
  2. Clean up upfacing camera surfaces. YES!
  3. close gate and set up fence. YES!

Toniz_Floor Site
  1. Fence and gate power: 12 v.
  2. Panel and Batteries: - v; - amps; - amps. (about 7:00 am local time)
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)

  1. downloading data YES!
  2. Check MD-9 system connections YES!








  1. Soil CO2 profile: CR23X5 – soil CO2 profile

  1. Close gate and set up fence. YES!
