Summary: Regular data download and site maintenance

Arman and I arrived at 11:30 PST. The water level was high and the staff gauge read 6.2ft at 11:50 PST. It was sunny and quite breezy. Arman collected water sample for the upcoming school fieldtrip.

At the tower, I dowloaded MET, GHG, and camera data. Arman cleaned flux and rad sensors and topped off the wash reservoir, which was 85% full.

Arman measured the surface and porewater conductivity.
Surface, 2207uS, 19.7C
Porewater, 6.03mS, 21.0C

The 7500 read: 434ppm CO2, 616 mol/m3 H2O, 25.1C, 101.6 kPa, 98 SS – 99 after cleaning
The 7700 read: 2.0 ppm, RSSI 45 – 87 after cleaning

We left at 12:00 PST.
