Sherman Island - Methane Study

Date jan 8 2008

Day 8

Standard Time in: 11:30 Out: 2:00

Who: MD, Ben & Kate

Weather: clear sky, light wind

Phenology: dead weed , few patches of short 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: 11.6
  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 -0.25 Ts 11.84 u -0.21 H2O 1.8526 v -0.66 CO2 1.784 CH4 2.6
  1. Methane Sensor (type Scroll Scroll 2)

Methane Hi-flow ppm

2.55

Cell Pressure – near 159

97.88, after replacing the 2micron 135.5

Cell Temperature

17.33

Mirror time

16.50

Sample rate

10 Hz

Methane low flow put back in high flow !

Pump status

Filter Status

Water traps

2 cm of water in the first

  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.

Other Notes:

Water table depth (from the top of the well) 2.91

USB-COM CR10X > PC, it’s not working, a lot of ants around it
