Summary: Regular data collection, wetland dead

Arrived at 14:10. It was clear and sunny with a light breeze. The water is very dark and dirty. The vegetation is totally senescent and there is no green vegetation left.

We collected USB GHG data, collected met data, collected camera. Tul1_Ts16 temperature still not working. The camera only had pictures up to Dec 14. All else looks good.

No live ants in the datalogger box this time but left some mothballs just in case. Also left some mothballs in LI7550 box and in multiplexer box for soil temperature.

The RSSI for the LI7700 was lower than it should be (should start automatic cleaning cycle when it drops below 30). Tested water sprayer and motor. All was working. There were lots of spider webs which might have caused the RSSI to drop below the level but could not get cleaned of with the automatic cleaning.

Refilled wash water reservoir, was 3/4 full. Cleaned eddy flux sensors and radiation sensors.

LI7500 readings:
CO2 423.8 umol/mol
H2O 391.3 mmol/m3
T 14.75 Celsius
P 101.7 kPa
SS 84.2 -> 88.5 after cleaning

LI7700 readings:
CH4: 2.45
RSSI: 21 -> 79 after cleaning

Left at 14:25
