Summary: Pepper weed in full bloom, water levels high, computer needed restarting, soil CO2 down due to low voltage condition.

We arrived about 16:00 PDT just to download data and clean the flux instruments. Sara, Iryna, Dillon, and Jenny were there earlier to do regular field work. It was windy and warm. The water under the bridge was high, close to lapping up on the road at one place. The pepperweed was flowering heavily.

The mouse pointer wasnt working and Joe had to fiddle quite a bit with the computer, including a couple restarts to get it working again. No known cause.

The LGR read 15:13, 23.68C, 136.90Torr, 16.809usec, 10Hz, 1.911ppm CH4. The pressure was adjusted to 148.2Torr.

The 7500 read 16.27mmol/m3 CO2, 274mmol/m3 H2O at 248 AGC.

The soil CO2 sensors were down again due to a low voltage condition on the charge controller. I reset it. I need to buy a new power supply.
