Sherman Island: 2014-10-30 09:15:00 (DOY 303)
Author: Joe Verfaillie
Others: Patty

Summary: Standard data collection, high ambient CH4, CO2, brought computer in for repair.

Sherman
2014-10-30

I arrived about 9:15 with Patty. It was cool with a high thin overcast and almost foggy. There was a very light breeze. The field looks trampled and most weeds are beginning to senesce. Ambient CH4 and CO2 were very high.

The LGR read: 9:23, 24.41C, 129.5Torr, 14.692usec, 10Hz, 3.633ppm CH4 – pressure adjusted to 148.0Torr.

The 7500 read: 21.54mmol/m3 CO2, 660.39mmol/m3 H2O, 101.72kPa, 18.46C, 247diag

The computer crashed and would not restart. It would boot to windows and then immediately restart. I brought it in for repair. I connected directly to the CR10X and CR1000 to check things. Theta probe 2 is reporting –INF. The met CR10X will not go two weeks before overwriting memory!

I pulled the pipe from the north well for use at Twitchell Rice.

Patty did spectral, veg height and Moisture Point noting fresh cow paddies in the transect. The spectral data has reference (upward) samples at each point.

Veg Height (cm): Tape measure from ground to top of plant
40, 70, 40, 40, 30, 20, 70, 77, 40, 100, 80, 57, 77, 38, 17, 13, 71, 50, 70, 50, avg = 52.5, stdev = 23.76
