West Pond
2018-07-12

We arrived at 11:25. Weather was sunny, warm, mostly clear (few clouds were present) and there was a very slight breeze.

Water level was low. The West Pond pump was on and releasing a strong flow of water.

Kuno cleaned flux and rad sensors. The wash reservoir was mostly full and topped off.

We swapped 7500 sensors: sn 75H-2514 came down and sn 0042 went up. Daphne uploaded new configuration files, updated the pressure coefficients, and reset the box.

Alex put up a staff gauge on the scaffolding below the wash reservoir. The water level was 55 cm.

Daphne collected USB, cam, and met data. When collecting cam data, the card supposedly had a problem but the files still opened.

We left at 12:02.
