Summary: Regular data collection/cleaning, higher water level, Canon camera still underexposing photos--removed

2022-02-17
Mayberry

Carlos and I arrived at 13:55 PST. It was mild and sunny with a little breeze. The water level has gone up here—the staff gauge read 70cm. Lots of birds around and ducks/geese flying overhead.

We noticed there is a little veg under the Rnet sensor, so it is not seeing solely water. The incoming side of the Rnet sensor has white spots that couldn’t be wiped off.

I downloaded met, cam, and USB GHG data. I also downloaded the picam photos (cleared its memory) and downloaded the Stardot photos. We removed the Canon camera to bring back to the lab for testing—it still has dark/underexposed photos in the afternoon. We have 2 other cameras here to measure GCC, although the wetland will remain brown for a while so I don’t think we will miss much.

Carlos cleaned flux and rad sensors and topped off the wash reservoir.
