Summary: Swapped LI7500, regular data collection, cut back willow.

Arrived around 11:40am. Not as much cattail fluff here as at East End. Lots of ants in the datalogger box. Tried to stuff some more putty in the holes where they are coming in. Green tules and cattail are coming up here as well.
Collected USB GHG data, collected met data from CR1000, collected camera card pictures.
Cut back willow. Cut off some larger branches that started growing over the tower scaffolding.
LI7700 showed an error in the LI7500 software. Did not seem to be connected correctly. Might not have been recording data.
Swapped the LI7500. Took down sn 0065, replaced with sn 1594.
LI7500 readings before swap: CO2: 424.19, H2O: 511.9, SS: 81.01, T: 20.97, P: 101.72
after swap: CO2: 422.03, H2O: 518.8, SS: 99.92, T: 21.11, P: 101.70
LI7700 readings: CH4: 2.16, RSSI: 65.2 -> 84.3 after cleaning
After the swap updated LI7500 config settings for calibration. Also updated settings for LI7700 to reconnect to Licor datalogger. LI7700 error now gone.
After the data collection I dropped the USB to RS232 adaptor into the water. Was able to recover it but it got really wet. We were not able to connect to the sonic to check the firmware version with the wet connector.
