Summary: Regular data collection/cleaning, cut 7700 power cable--fixed temporarily, cleaned picam window

East End

Carlos and I arrived at 15:20 PDT. It’s been about 3 weeks since the last site visit. It was warm, windy, and mostly clear. The tules are tall and green and most have flowers. The cattails are also starting to get tall. The staff gauge read 61cm.

I accidentally cut the 7700 power cable while trimming the plants around the tower. I fixed it temporarily with a 4-pin screw terminal. It needs a replacement power cable next time.

I trained Carlos on downloading the data while I cleaned flux and rad sensors. He downloaded met, cam, and USB GHG data. He downloaded miniDOT data and I swapped the desiccant for the miniDOT and water level sensors. The wash reservoir was 90% full, refilled.

I opened the picam enclosure because there were was a spot in the middle of some photos last time. The enclosure seal is getting old and I had a hard time stuffing it back into its place. I knocked off one offset from the camera board when unscrewing the teeny tiny screws. After cleaning, I checked the camera website again to confirm the field of view was about the same as before.

LI-7500 readings: CO2 426ppm, H2O 334ppm, T 21.9C, P 102.3kPa, SS 94--> 98 after cleaning
LI7700 readings: CH4 2.0 ppm, RSSI 83 after cleaning

We left at 16:45 PDT.
