Summary: Regular data collection/cleaning, cable gate lock cut, water level going down

Mayberry

Ari and I arrived at 13:45 PDT. It was hot with a slight breeze. The middle lock on the cable gate has been cut, but the lock was still neatly in its proper slot in the gate. We also noticed the levee road beyond the gate had been mowed--Ari hypothesized the person mowing didn't want to cut the lock, but had to in order to finish their job, which is why they placed the lock back after they were mowing. The water level at the tower is still dropping. Lots of mosquito fish in the water. The staff gauge read 42cm.

I downloaded met, camera, USB GHG, and miniDOT data. We swapped the desiccant for the miniDOT and the water level sensor. I downloaded the picam and Stardot camera data. I downloaded the FD data and cleared its memory.

The 7700 optics RH had dropped from around 24% to 11% since we swapped the desiccant last week, so we know the new drierite is working.

I checked the conductivity sensor as part of its routine check and the orifice was clear. I changed the eddy clock +1min to match the laptop time. Ari cleaned flux and rad sensors and we topped off the wash reservoir.

I brought a new pluggable power strip but waited to switch it next time. This site still needs a diffuse PAR sensor since we relocated the one at SW to the new Dutch Slough site.

LI-7500 readings:
CO2 410ppm
H2O 730ppm
T 32.2C
P 100.8kPa
SS 98 --> 100 after cleaning
LI7700 readings:
CH4 2.04
RSSI 52 --> 81 after cleaning

We left at 14:15 PDT.
