Summary: Standard data collection, replaced filter and check valve in wash box.

Mayberry
2015-12-11

I arrived about 10:50 with Elke. It was mostly clear, cold and windy. The storm over night left the air feeling crisp and clean. The roads were not too wet, but the ground seems wet through. The cattails are almost completely brown. The water level was near the top of the post in the channel.

There is a new lock on the cable gate and a sign that says to keep it locked. The key we have for the previous lock works with the new lock.

The 7500 read: 407.ppm CO2, 456.7mmol/m3 H2O, 101.4SS, 14.16C, 101.2kPa
The 7700 read: 1.86ppm CH4, 30.0RSSI â€“ 74.5 after cleaning.

I reinstalled the filter and check valve in the 7700 wash box from the bottom of the reservoir to the pump inlet. I had to chase a bunch of wasp off beforehand. The pump came loose from its bracket but I was able to reattach it.

Elke got a brief intro to the site and our data collection.

We did not service the water sensors.

I forgot to bring and swap the 7500 - needs to be done next time.
