Summary: TC2_32 was not working; replaced inlet filter; took soil moisture; downloaded data from laser and for Sherman Island.

Sherman Island - Methane Study

Date: 31 August 2007

Day: 243

Standard Time in: 10:40 Out: 12:30

Who: MD

Weather: few clouds, windy

Phenology: almost dry peeper grass; some green still in flower, smaller green weed appears

Tasks

  1. check and download data at Sherman Island
  2. download data from laser
  3. Take soil moisture
  4. replace inlet filter

Check list

  1. Fence and gate power: OK
  2. Datalogger Solar Panel and Batteries: 13.8
  3. Reading from Gillsonic (H2O and CO2 should be in the range of 0 – 5 v.)

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.
