Summary: Regular data collection/cleaning, removed eosGP CO2 sensor

East End

Joe and I arrived at 13:20. It was cool and mostly cloudy with a small breeze. Lots of cattail fluff everywhere.

Joe cleaned flux and rad sensors and topped off the wash reservoir. I downloaded met, camera, USB GHG, and miniDOT data. Last visit this wash reservoir was full while all other sitesâ€™ were empty, so today I checked the 7700 wash cycle settings and tested the spin/spray, which all seemed fine. The EE 7700 must be staying cleaner than other 7700s for some reason. I left mothballs inside the met box.

I forgot to check the water level on the staff gauge.

The eosGP CO2 sensor (sn GP20140019) had a CO2 reading of ~5000 mV for the last week, and there was no change when we took it out of the water, so we brought it back into the lab for testing.

LI-7500 readings:
CO2 437ppm
H2O 394ppm
T 12.8C
P 102.2kPa
SS 95-->95 after cleaning

LI7700 readings:
CH4 2.3ppm
RSSI 44 --> 80 after cleaning

We left at 13:45.
