When: Date: 3/9/2005 , Day: 068 , Watch Time: 10:52 .
Where: Tonzi/Vaira Ranch
Who: DDB, SM, JC
Weather: Sunny
Phenology: some oak leaves just coming out, maybe the end of week will out, grass blooming, yellow, purple followers

Tasks

1. DDB checked the over-range problems of soil CO2 profile sensors
2. soil moisture
3. Alex’s samples
4. leave samples: Vaira grass, Tonzi understory grass
5. read dendrometers
6. Jorge measured soil respiration using Li-cor

Soil CO₂ Profile system – Over-range
Symbol: W – under tree, E – open
Maybe sensors with larger range are needed.

Vaira_Grass Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13.8 v; 12.8 amps; 1.8 amps.
3. Files are D068. Just screen name is not updated.
4. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)

1. Batt volt 11.91, T paro 28.7, soil Tc 19-19.3.
2. Mattias borrows LED system.
3. DDB cleaned up dirts on Rnet sensor.
4. Closed gate and set up fence.

Tonzi_Tower Site – Ted and Hank were working there.

DDB and Ted double checked Tsoil probe by pairs T probe from Licor next to Tsoil probe. Both ~14.5^oC.

Toniz_Floor Site

1. Fence and gate power: >12 v.
2. Panel and Batteries: 13. v; 19. amps; 1.9 amps.
3. Reading from Gillsonic screen before downloading data. (The value of H₂O and CO₂ should be in the range of 0 – 5 v.)
