Who: MD, DB, Ben

Weather: overcast windy

Phenology: patches of green grass

Tasks

  1. check and download data at Sherman Island
  2. download data from laser and calibrate

Check list

  1. Fence and gate power: OK
  2. Datalogger Solar Panel and Batteries: 10.71
  3. Reading from Gillsonic (H2O and CO2 should be in the range of 0 – 5 v.)
Time Path/File D:\Data\SI07 .raw mean std mean std w 0.2 Ts 10.0 u -4.6 H2O 1.11 v -2.5 CO2 1.84 CH4 2.06
  1. Methane Sensor (type Scroll Scroll 2)

Methane Hi-flow ppm

Methane low flow put back in high flow !

Pump status

Filter Status

Water traps

  1. If Swapping Li-7500 Analyzer. (Remove SN# ; install SN# )
  2. Check the fans of air temp. and relative humidity sensors
  3. Check MD-9 system connections
  4. Check CR23X with two multiplexers and sensor values
  5. Check levels of Radiation sensors, clear up surfaces.

Closed gate and set up fence.
