Summary: Regular data collection/cleaning, no photos on card--fixed?, changed eddy clock +1:20min

West Pond

Ari and I arrived 15:40 PDT. It was warm and breezy with clear skies. The wetland look nice and green and the staff gauge read 90cm, same as the last visit.

I downloaded met, USB GHG, and miniDOT data. We noticed there was a fine black sediment accumulating on the white plastic miniDOT body. I swapped desiccant for the miniDOT and water level sensors. Ari cleaned the flux and rad sensors and topped off the wash reservoir.

I changed the eddy clock +1:20 min to match the laptop time and restarted logging afterwards.

I checked the conductivity sensor as part of its routine check every 3 months--the orifice looked clean.

Again, there were no photos on the card. Joe had mentioned in a previous field note that he couldn’t delete the month-specific folder, so I think I deleted the DCIM folder, but I’m not sure. We put the card back in the camera and waited for it to take a photo. The photo was stored properly on the card, so I don’t know what was the issue before. Before we left the site, we checked that there was a second photo on the card at the appropriate time. I changed the camera clock +7min from 15:15 to 15:22 to match the laptop time. Hopefully there is a full set of photos next time.

The 7500 read: 404ppm CO2, 748mmol/m3 H2O, 29.8C, 101.1kPa, 100.9SS – 102 after cleaning
The 7700 read: 1.04ppm CH4, 50RSSI – 84 after cleaning

We left around 16:25 PDT.
