Summary: Water level higher again, standard data collection, Sherman wetland news from Bryan

Mayberry
2015-11-11

I arrived about 10:15 with Kyle. It was clear sunny and mild with no breeze. The water level is higher right at the top of the fence post in the channel. The vegetation is turning brown.

We met Bryan and Jim on the way in. Bryan says the new wetland construction is complete. He also says that we will need to put one of the new towers there to please the CDFW folks who want to know how much of a sink it is. Bryan also has a time lapse camera set up there that we may be able to use for GCC.

More dead wasps in the data logger box and live wasps in the wash reservoir box. The reservoir was about half full â€“ refilled.

The 7700 read: 2.03ppm CH4, 50Rssi â€“ 76 after cleaning
The 7500 read: 479ppm CO2, 244mmol/m3, 79.2SS, 15.8C, 102.99kPa
After cleaning: 429ppm CO2, 429mmol/m3, 101.96SS

The 7500 had a drop of water on its lens and there were lots of spider webs on all the eddy sensors.

We did not service the water sensors.
