Summary: Regular data collection/cleaning, wetland starting to senesce, weed control needed for flowmeter

2022-09-28
Gilbert Tract

Robert and I arrived at 10:30 PDT along with Patrick, a MBA student who is interested in carbon sequestration start-ups after graduation. It was a beautiful fall day, mild and breezy with great visibility. The wetland is starting to senesce.

At 9:50 PST, the staff gauge read 50cm.

I downloaded met, cam, and USB GHG data. Robert and Patrick cleaned flux and rad sensors. The reservoir was 80% full; it was refilled. I changed the eddy clock +45sec from 9:40 to 9:40:45 and restarted logging.

The 7500 read: 323ppm CO2, 553mmol/m3 H2O, 21.4C, 101.6kPa, 97SS – 107 after cleaning
The 7700 read: 2.1ppm CH4, 51RSSI – 84 after cleaning

We got to Flo (the flowmeter) at 11:04 PDT. I synched the clock with the laptop time, downloaded data, and restarted data logging. I'm seeing more drops in the depth data, and there's lots of submerged aquatic vegetation in the sensor area. We need to come back at low tide with waders to clean it up more.

We left at 11:10 PDT.
