Summary: Regular data collection/cleaning, hazy air, water level still low

2020-09-01
West Pond

I arrived at 15:05 PDT. It was a windy and hazy day with occasional gusts. The water level is still too low to be read on the staff gauge. There was no water coming from the inlet, even though the inlet was Â¼ open. Bryanâ€™s e-mail to Ari said the fish screen work on Twitchell Island should finish by the end of the week, and then they will turn the siphon on.

I downloaded met, camera, and USB GHG data. I cleaned flux and rad sensors. I topped off the wash reservoir and changed the water level desiccant. There was damp muck under the tower and the water sensors (eosGP, miniDOT, conductivity) were all hanging in the air.

LI-7500 readings:
CO2 400ppm
H2O 650ppm
T 25.8C
P 101.1kPa
SS 99--> 100
LI7700 readings:
CH4 2.0ppm
RSSI 47--> 71 after cleaning

I left at 15:30 PDT.
