Summary: Regular data collection, water level a little low, LI7700 wash reservoir tubing leaking, needs replacement.

Arrived at 13:50. Sunny, breezy, mostly clear skies, but some high thin sparse clouds. This wetland is quite green. The water level looked a little lower than usual, maybe a 2 to 4 inches.

Filled the LI7700 wash water reservoir, was completely empty and the RSSI was very low (6.7). Cleaned the LI7500 and LI7700.
Tested the LI7700 wash cycle and found a few holes in the tubing. Tried to tape up the holes as best as we could, but the tubing is still leaking quite a bit and not much water comes out at the top to clean the mirror. Tubing needs to be replaced.

Collected USB GHG data, collected met data, collected camera pictures. Tc16 is still reading â€“INF.

LI7500 readings:
CO2 398.74
H2O 664.1
T 22.33
P 101.45
SS 82.49 -> 85.7 after cleaning
LI7700 readings:
CH4: 2.09 -> 1.92 after cleaning
RSSI: 6.7 -> 77.1 after cleaning
