Summary: Field drained but saturated still. Installed fake batteries in autocam. Regular field work. All well.

Twitchell Rice
2014-08-27

We arrived about 12:30 PDT. Hot, very light breeze, and sunny. Lots of wasps buzzing around but I couldn’t see any nests. The field is drained, but the surface still saturated. Rice seeding heavily. Sara did veg height while I attended to the tower. I installed some fake batteries that Joe made to feed line power to the camera. The camera and the autocam program started fine.

7500 readings:
CO2 = 390 ppm (385 after cleaning)
H2O = 600 mmol m-3 (642 after cleaning)
signal strength = 93.06% (93.6% after cleaning)
p = 102.0 kPa
t = 29 C
sos: 351.7 m s-1

7700 readings:
CH4 = 1.9 ppm (same after cleaning)
RSSI = 46% (71% after cleaning)
Reservoir was full.

Met looked good.
