Summary: Tall tules, regular data collection/cleaning

2024-05-23
East End

Robert and I arrived at 13:35 PST (14:35 PDT). It was sunny, warm, and windy. The tules have gotten tall! We used Robert as a ruler and measured some of them as ~4m tall. The reeds are blocking the precip bucket, but I assume we're done with rain for the season.

The staff gauge read 81cm.

I collected met, cam, USB GHG, and miniDOT data. I changed the eddy clock +1:15min around 13:50 PST to match the laptop time and restarted logging. We swapped the miniDOT and water level desiccant. The reservoir was 90% full; Robert refilled it. Robert cleaned flux and rad sensors and measured the surface water conductivity.

Sample, temperature-compensated conductivity, temperature
Surface, 2475 uS, 15.3 C

The 7500 read: 427ppm CO2, 366mol/m3 H2O, 28.1C, 100.9kPa, 95SS – 96 after cleaning
The 7700 read: 2.0ppm CH4, 76 after cleaning

We left at 13:55 PST (14:55 PDT).
