Mayberry
2016-09-29

I arrived about 10:10am with Dennis, Kyle and Sam. It was sunny, breezy and cool but warming up. The vegetation continues to decline. The water is lower with the top DO sensor out of the water and the conductivity sensor was partially out of the water. I lowered the conductivity sensor. The water was also brown instead of very green of the previous weeks. Dennis lost his Licor hat in the swamp due to a gust of wind.

The 7500 read: 400.2ppm CO2, 696.2mmol/m3 H2O, 17.95C, 101.6kPa, 101.2SS â€“ 103.4 after cleaning
The 7700 read: 1.94ppm CH4, 34.9RSSI â€“ 75.9 after cleaning
Both gas analyzers had black grime on their leading edges. The reservoir box was full of wasps â€“ BE CAREFUL

The 23x is having problems. It seemed to be functional but all analog channels were -9999. And I had a hard time getting the data off. It would start to download and then quit. I think I finally got it all. The data turned bad on day 270 at 15:30. I tried reinstalling the program but this did not improve things. I started to move some sensors around and it started working. I think there might be a bad power connection somewhere. Pushing on the wiring panel seemed to fix the problem. It was running when we left, but Iâ€™ll try to swap it out next week.
