Summary: regular data download and maintenance | plants filled in | mothball added in CR10X boxes

Prior to the site visit, we stopped by the fruit stand and got some nice cheeries + peaches. When we entered the Twitchell gate, we saw some people working ( we later noticed, as we were leaving, that they were doing manual weeding). We thought to show Joy the old rice field, but that area had been filled in with weed, so we went for a little advanture before the scenic lunch by the levee.

Dennis, Joy, and I arrived at East End at ~1245, it was breezy and sunny. The water level was pretty high, ~83cm at ~1305.

At the tower, I collected the MET, flux, and camera data. Dennis cleaned the MET and flux sensors. The LI77 washbox was ~85% full. I reset the flux clock, which was ~1 min behind. Afterwards, I restarted the logging. Joy and I also added mothballs to CR10X boxes (shadow band + main enclosure).

7500 read: 417ppm CO2, 608mmol/m3 H2O, 24.5C, 101.2kPa, 97.8SS - 98.5 after cleaning
7700 read: 2.1ppm CH4, 44RSSI - 80 after cleaning.

Dennis took the water conductivity:
Surface, 186.0uS, 16.5C

We left the field at ~1320 and went to Mayberry
