Mayberry

Robert and I arrived at 10:05 PDT. It was breezy, sunny, and mild. The staff gauge read 41cm. The water level has gone down about 20cm since last week when Kyle and I installed the pore water sippers. Kyle decided that monthly sampling of the porewater should be ok so we skipped it today and we'll take measurements next visit. The wetland is continuing to green up.

I downloaded met, cam, and USB GHG data. Robert cleaned flux and rad sensors. I changed the eddy clock +40sec from 9:14 to 9:14:40 to match the laptop time and restarted logging afterwards. The wash reservoir was 80% full and refilled.

Robert trimmed some of the reeds by the boardwalk and accidentally cut the precip sensor wire. We fixed it temporarily with a screw terminal.

The 7500 read: 430ppm CO2, 630 mmol/m3 H2O, 20.1C, 100.6kPa, 100SS – 102 after cleaning
The 7700 read: 1.99ppm CH4, 57RSSI – 87 after cleaning

Stomping down some of the weeds last week did help clear up the pathway a bit. I stomped a few more down today and also stomped down the weeds growing around the solar panels. They were shading the panels but we should have plenty of sunlight in the next few months.

We left at 10:40 PDT.
