East End

Kyle, Camilo, and I arrived at 12:30. It was an overcast and cool day with big, fluffy cumulus clouds. The water level was 34 cm.

Kyle cleaned flux and rad sensors; there were a lot of cattail fluff and spiderwebs in the 7700. The wash reservoir was empty; we refilled it. I downloaded met, camera, USB GHG, and miniDOT data. The Nikon camera was out of batteries so we did not take a reference GCC photo.

LI-7500 readings:
CO2 425ppm
H2O 560ppm
T 16.7C
P 101.7kPa
SS 102--> 106 after cleaning
LI7700 readings:
CH4 1.97ppm
RSSI 20--> 80 after cleaning

Camilo walked around in the wetland trying to collect enough methane in a funnel (precipitation bucket funnel) to light on fire, but there wasnâ€™t as much as he hoped.

We left at 12:55.
