Summary: Regular data collection/cleaning, water level going down, spiderwebs on 7500--cleaned

2022-08-30
West Pond

Ari and I arrived at 13:10 PDT. It was sunny, warming up, and muggy among the plants. Water level is decreasing. The staff gauge read 41cm.

The conductivity sensor was out of the water, so I pulled more slack out of the extra coiled cable and dropped the sensor into the water under the lower boardwalk by the staff gauge. Fewer reeds there to impede the sensor.

I downloaded met, cam, and USB GHG data. There were small ants and a pile of their eggs in the met box so I left them some mothballs. Ari cleaned flux and rad. There were a bunch of spiderwebs in the 7500, so the SS was a low 73. CO2/H2O numbers looked better after cleaning.

We topped off the wash reservoir. There were quite a few wasps in the reservoir box so I just left the lid open.

The 7500 read: 360ppm CO2, 1000mmol/m3 H2O, 28.7, 101.3kPa, 73SS
After cleaning, the 7500 read: 400ppm CO2, 778mmol/m3 H2O, 29,1C, 101.3kPa, 102SS
The 7700 read: 2.0ppm CH4, 71RSSI – 83 after cleaning

We left at 13:35 PDT.
