Summary: Regular data collection, wetland dead

Arrived at 13:20. It was clear and sunny but hazy in the distance. Wetland is dead. The water level was normal.
The tower seems to be leaning away from the boardwalk. Might need to get stabilized at some point.

We collected USB GHG data, collected met data. All looks good. No ants in any of the boxes, but we left some mothballs in them just in case. Collected camera. The camera was off and there were only 118 pictures (up to Dec 11) on the card.

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