Summary: Power down due to GFI, LGR calibration.

I arrived about 9:30PST with Jaclyn and Sara. It was cold and foggy with a little breeze. The fog was breaking up and the spots of sunlight were warm. The water level in the field might be a bit lower. We saw some geese, but not a lot of birds in the fields yet.

The power was out again when we arrived due to the GFI outlet on the generator. I reset it and eveything came up. Jim stopped by and said that he would replace the outlet on the generator.

The LGR read:
9:25PST, 7.15C, 139.03Torr, 14.361usec, 10Hz, 2.757ppm

We calibrated the LGR with a 3.276ppm tank with 400psi. Last cal was Oct 10, 2011.
9:56PST, 9.53C, 156.07Torr, 14.341usec, 1Hz, 3.357ppm
After cal it was right on. When we left it was back in high flow at 10Hz and pressure was about 141Torr, I did not adjust the bypass valve.

Data was collected including the new autocam images.

Sara washed the solar panels.

Jaclyn collected water samples.
