Summary: Regular data collection/cleaning, muggy, green and happy plants, changed eddy clock +1min

East End

Ari and I arrived at 16:35 PDT. It was warm with clear skies and generally breezy, but muggy among the green and happy plants. The staff gauge read 58.5cm.

I downloaded met, cam USB GHG, and miniDOT data. I swapped desiccant for the miniDOT and water level sensors. I changed the eddy clock +1min from 15:45 to 15:47 to match the laptop time. I restarted logging afterwards. Ari cleaned the flux and rad sensors and topped off the wash reservoir.

The miniDOT chain was kind of floating when we arrived so when Ari deployed the miniDOT after download, she threaded it through the underwater veg so it was hanging freely.

I checked the conductivity sensor as part of its routine check every 3 months--the orifice looked clean.

I checked the 7700 fuse and it looked fine. There was no moisture in the fuse cap.

The 7500 read: 414ppm CO2, 615mmol/m3 H2O, 30.7C, 101.0kPa, 93 after cleaning
The 7700 read: 2.0ppm CH4, 35RSSI – 79 after cleaning

We left around 17:10 PDT.
