Summary: Inlets running but no water under scaffolding, east pond very low too, ants infestation improving, measured sensor locations

West Pond
2013-07-10

I arrived about 12:30 with Laurie, Yanel and Cristina. It was clean and hot with a light breeze from the northwest. The water inlet was running but there was no water under the tower scaffolding and the East Pond water level was about a half meter below the boardwalk.

The ants were still poking about the 7550 box. I removed all the baits and used some canned air to blow the ants and all the debris out of the boxes. Just before leaving I blew a few more ants out and replaced the baits before closing it up.

The 7500 read: 381ppm CO2, 677mmol/m3 H2O, 86% SS, 28.96C, 100.94kPa
The 7700 read 1.96ppm CH4, 35.2 RSSI rising to 70 after cleaning

We measured the heights of some of the instruments and I took a photo with ruled square to get lateral positions. In the folded position the center of the eddy sensors is 4.7 meters above the muck. The soil temp sticks are 48 inches long and we measured the height of the top of the stick above the muck. The stick near the entrance to the scaffolding is 45cm agl, and the stick near the well is 59cm agl. The top of the well pipe is 76cm agl. Lateral distances between the eddy sensors are

Sonic to 7700 36cm
Sonic to 7500 20cm
Sonic to HMP60 100cm

No water samples - no water.
