Summary: PG&E turned off power due to non-payment. Should be up shortly. Data download. Some fieldwork.

Sherman
2013-11-21

We arrived about 08:15 PST. It was cold, super windy, and overcast. The field was muddy due to the recent rains. We arrived to find the main power off (although the CO2 flux system was still running on battery). After some investigation and a chat with Joe it was determined that PG&E shut off the power due to non-payment. Good timing of our arrival! Apparently payment and power reinstatement should happen shortly.

Without power, our trip was limited, so I cleaned the instruments and downloaded flux and autocam data while Laurie did well depth, moisture point, and a veg height transect. No spectral measurements -- after coming back from calibration, the spectrometer head didnt make it back into the equipment we grabbed for today.

Veg Height (cm): Tape measure from ground to top of plant
0, 53, 0, 37, 1, 10, 0, 30, 2, 2, 40, 40, 1, 0, 0, 1, 40, 70, 0, 38, avg = 18.3, stdev = 22.56
