Summary: Standard data collection, water level low but inlet running, reinstalled autocam, swapped 7700 wash tubing

West Pond
2015-08-19

I arrived about 12:15 with Patty. It was clear, sunny and warm with a nice breeze. The water level was very low but the inlet was running. The CO2 sensor was almost out of the water. The vegetation looks like it is beginning to yellow.

The 7700 read: 1.93ppm CH4, 32.1RSSI â€“ 84.1 after cleaning
The 7500 read: 381.1ppm CO2, 779.1mmol/m3 H2O, 86.9SS, 24.4C, 100.8kPa

We tested the 7700 wash spray and found a leak in the tubing. We swapped out the entire length of tubing.

We reinstalled the autocam. I did not have the screw to mount the camera so it is just sitting loose in the enclosure. Be careful not to bang the power connector with the enclosure top when you close it.

Wasps were taking interest in some bolt holes in the scaffolding. I shove some pieces of Tule into the holes.
