Sherman Wetland
2018-10-04

I arrived with Dennis at about 14:10. We got a new key from Bryan earlier in the day for the main gate. It was warm with patchy high thin clouds and a stiff cool breeze. The water level was 66cm? Maybe a little higher than last time. The wetland is still mostly green and growing except for some patches of cattails or tules on higher ground that died when the water was low. Recent light rain left the gas analyzers (especially the 7500) dirty.

We swapped the 7500: sn 75H-2667 came off and sn 75H-2180 went on. The correct pressure coefficients were added and the box restarted.
2667 dirty read: 380ppm CO2, 844mmol/m3 H2O, 22.7C, 101.5kPa, 93.8SS
2667 clean read: 403ppm CO2, 644mmol/m3 H2O, 22.7, 101.5kPa, 105SS
2180 installed: 396ppm CO2, 668mmol/m3 H2O, 22.7C, 102.1kPa, 99.6SS

The 7700 read: 2.0ppm CH4, 40.0RSSI â€“ 76.6 after cleaning
The wash reservoir was topped off.

I collected the miniDot data. The probe is now in a patch of cattails that have encroached.

Cleaned bird poop out of the tipping bucket.

We left at 14:50
