East End
2021-11-04

Daphne, Robert, Vona and I arrived at about 12:30. We stopped for lunch on the levee above the pump station. They were working on the pump station and turned on one of the pumps while we were there. The river seemed to be flowing backwards as the tide came in. It was mild and partly overcast with a nice breeze. There was an interesting collection of poop on the boardwalk, lots of seed, lots of crayfish, and just black. Also a big praying mantis â€“ about 6in long. Water level was 35cm. The cattails are turning yellow/brown.

We tested the tipping bucket. We got 50/50 tips; all is well after last visitâ€™s adjustment.

Daphne collected flux, met and camera images.
The 7500 read: 414ppm CO2, 610mmol/m3 H2O, 20.6C, 102kPa, 102SS after cleaning
The 7700 read: 1.99, 83RSSI after cleaning
Robert cleaned the instruments and we're pretty sure we topped up the wash reservoir.

I opened up the pi-cam box and unfastened the camera so that I could clean a spider web out of the little gap between the lens and the glass window. It seemed to go okay and I didnâ€™t have the cycle power on the Pi.

We left at about 13:00 PDT
