Mayberry

Arman and I arrived at 10:35 PST (11:35 PDT). It was warm and breezy. The tules are flowering and the cattails have both male and female flowers. There’s a big patch of thatch directly below our radiometers.

I downloaded met, cam, and USB GHG data. The staff gauge read 47cm. We lowered the eddy post temporarily for Arman to clean the flux and rad sensors. Arman topped off the wash reservoir and we measured the surface water conductivity.

Sample, temperature-compensated conductivity, temperature
Surface, 1409 uS, 21.5 C

The 7500 read: 423ppm CO2, 780mol/m3 H2O, 24.4C, 100.8kPa, 99SS – 100 after cleaning
The 7700 read: 1.96ppm CH4, 35RSSI – 72 after cleaning

We left at 10:55 PST (11:55 PDT).

There seems to be more thatch under the radiometers than in the rest of the wetland
