Summary: Deployed new eosense CO2 probe, collected met data

We arrived around 13:20. It was sunny, some clouds, calm. The water around the tower was higher than before. The platform was mostly submerged, and we kept our feet dry getting to/from the tower by laying a ladder down to act as a boardwalk. The whole tower is tilting and probably needs to be adjusted at some point.

We deployed an Eosense CO2 probe (sn GP20150109) and re-wired it to the CR1000.

I refilled the wash reservoir; it was 1/2 full.

Joe cleaned the 7500 and 7700.

LI7500 readings:
CO2 404.4 umol/mol
H2O 297.2 mmol/m3
T 12.9 Celsius
P 101.9 kPa
SS 107.2 -> 107.5

LI7700 readings:
CH4: 2.01
RSSI: 42.8 -> 83.5 after cleaning

The camera was off - Joe restarted it.

In the future, we need to update the WP CR1000 program so that the eosense probes are read as differential (not single ended) measurements. We could also update the program to take out unneeded sensors.

We should add black split loom conduit to cables to protect them from the sun.
