When: Date: June 1 Day: 153 Watch Time: 14:55
Where: Sherman Island Methane Study
Who: MD & DB
Weather windy, mild, light clouds
Phenology Veg flowers, green-dry
Tasks
1. check and download data at Sherman Island
2. Take TDR soil moisture readings
3. checking methane pressure cell
Sherman Island Pasture Site
1. Fence and gate power: OK
2. Datalogger Solar Panel and Batteries: OK
3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 â€“ 5 v.)
4. Methane Sensor
a. Cell Pressure (near 159 Torr?): 85 â€“ 144.8**
b. Cell Temperature:
c. Double Check
i. Sample rate: 10Hz?: was set 1Hz
ii. Methane ppm Hi flow:
iii. Methane ppm, low flow (remember to put back in high flow:
iv. Pump status??
v. Filter Status: very dirty
*slow mode ** after cleaning the filter
5. downloading data
6. If Swapping Li-7500 Analyzer. (Remove SN# ; install SN# )
7. Check the fans of air temp. and relative humidity sensors
8. Check MD-9 system connections
9. Check CR23X with two multiplexers and sensor values
10. Check levels of Radiation sensors, clear up surfaces.
Closed gate and set up fence.

Other Notes:
The inlet filter was very dirty, we cleaned it with alcohol
The 4-comp radiometer was dirty, we cleaned,
next time remember to clean the sonic
