We arrived about 09:20 PDT. Weather was overcast, calm, about 14°C. The site, although moist from recent rains, continues to look cow trampled with a little dull green. Joe rebuilt the fence around the power pole and electrified it. Cows beware.

Joe removed all the old fencing around the power pole and pounded in the four fence posts again a little further out. He ran a copper wire through conduit unground from the existing cow fence to the new fence around the pole. He also replaced the wiring from the fence charger to the existing cow fence and added a new ground post for the charger.

I checked the tower, cleaned the instruments, and downloaded the data and autocam pics. Sara and Laurie did soil respiration, well depth, and moisture point.

LGR readings: 08:22, 23.16 °C, 133.65 Torr (adjusted to 146.6 Torr), 13.86 us, 10 Hz, 2.05 ppm

7500 readings:
CO2: 16.9 mmol m-3
H2O: 560 mmol m-3
P: 102.5 kPa
diag: 247

MET and SoilCO2 data streams looked good.

I resealed the hole where the ATI cable was fed into the box.

We left Joe to finish the new fence while we went to Mayberry.
