Summary: Regular data collection/cleaning, lots of tule flowers

2024-06-03
East End

Arman and I arrived at 11:35 PST (12:35 PDT). It was warm and breezy. The staff gauge read 81cm. The tules have tons of flowers, and the two different species of tules on either side of the road had notably different flowers. One species has taller reeds and just a few flowers on top. The other species is shorter and has a much denser cluster of flowers.

There were goats or sheep hanging out by the well pad. We had to open up one panel fence to get to the site.

The staff gauge read 81cm.

I downloaded met, cam, and USB GHG data. Arman cleaned flux and rad sensors and topped off the wash reservoir. We measured the surface water conductivity.

Sample, temperature-compensated conductivity, temperature
Surface, 190.3 uS, 17.6 C

The 7500 read: 415ppm CO2, 806mol/m3 H2O, 25.7C, 101.2kPa, 95SS – 96 after cleaning
The 7700 read: forgot to write CH4, 44RSSI – 74 after cleaning

We left at 11:55 PST (12:55 PDT).
