Summary: Regular data collection/cleaning, breezy, picam tilted--fixed

Mayberry

Robert and I arrived at 12:25 PST (13:25 PDT). It was sunny, warm, and breezy with an occasional gust. From the levee road driving in, the wetland looks mostly green. There is a patch just west of the tower that looks more brown/grey than most other areas. The staff gauge read 40cm.

I downloaded met, cam, USB GHG, and miniDOT data. We swapped the miniDOT and water level desiccant. I changed the eddy clock +1min around 12:33 PST to match the laptop time and restarted logging. The picam had tilted again; I adjusted it and need to tighten the bolt next time. Robert topped off the wash reservoir, cleaned flux and rad sensors, and measured the surface water conductivity.

Sample, temperature-compensated conductivity, temperature
Surface, 1623 uS, 22.5 C, no units written on field note so unit is a guess

The 7500 read: 430ppm CO2, 440mol/m3 H2O, 26.6C, 100.4kPa, 98SS – 100 after cleaning
The 7700 read: 2.04ppm CH4, 51RSSI – 73 after cleaning

We left at 12:50 PST (13:50 PDT).
