Summary: Installed 2 additional soil collars and 2 theta probes at soil CO2 profiles

We arrived around 8am local time to still conditions, foggy, and cool with the sun just rising over the bridge and lots of dew on the dead pepperweed. Lots of annual grasses have sprouted in the field. The cows seemed to have respected the new eletric fence around the power pole - no damage there.

Jaclyn took Moisture Point and well depth measurements but did not make spectral reflectance measurements due to the fogginess combined with the low angle of the sun making large shadows on the canopy. Joe installed the two lab-calibrated Theta probes adjacent to the soil CO2 profile to the right of the box. Jaclyn hammered in an additional chamber collar at each of the two soil CO2 profiles, to make 3 chamber flux replicates at each profile. The ditches near the tower were empty, but looked wet out in the far field.

At 8:05 the LGR read:
6:06, 23.30C, 150.42Torr, 13.832, 10Hz, 1.975ppm

In slow flow mode the pressure dropped to 30Torr and continued to fall. We probably need to swap it out again.

All the other data streams seemed okay.
