Summary: Removed top CO2 sensor from water and took back to lab, LI7700 rssi low, regular data collection,

Arrived 10:10. Sunny, warm, windy, clear sky with fog on the horizon. About half of the plants look dead, senescence isnâ€™t in clumps but homogenously mixed with live plants. Water level fairly high.

Methane was water reservoir filled, was about 2/3 full. Collected USB GHG data, collected met data from 23X, collected camera pictures. TUL1 TS16 =-INF. All other met data looks good.

Removed the topmost CO2 sensor sn GP20140011 and took the canister and wires back to lab. The other CO2 and dissolved oxygen sensors remained intact and in the water.
LI7700 had low rssi and the automatic cleaning mechanism should have turned on, so we checked the wash and both spray and spin worked when activated by the computer. We tried activating the cleaning mechanism by blocking the mirror with Kyleâ€™s hand, but after 2 minutes with no reaction we assumed it probably averages rssi over a time period before cleaning.
