East End
2018-08-23

I arrived at 11:50 with Kuno and Daphne. It was clear, sunny and mild with a cool breeze. It is very hazy with poor visibility. The cattails look a little brown at the tips maybe due to the recent low water level. However, the water level is back up to near normal again now. The water level was 27cm.

Kuno collected the data.
The 7500 read: 400ppm CO2, 718mmol/m3 H2O, 21.7C, 101.6kPa, 100SS
The 7700 read: 1.95ppm CH4, 44RSSI â€“ 79 after cleaning

The Eos water CO2 sensor readings look reasonable now but we should keep an eye on it.

The camera window looked dirty. In cleaning it I notice a smudge on the inside right in the middle of the lens which matches the spot we see in the photos. I moved the camera back and thoroughly cleaned the both the window and the lens. The window came loose in the cleaning and I put it back in with some putty but it needs some silicon next time.

I cut the reeds down around the tipping bucket and tide down the cable that had come loose.

We left at 12:20
