Summary: Cold and foggy, tules have been blown down

East End

Kyle and I had lunch and started the site visit at 12:20 PST. It was cold and foggy. We had a big storm last week and more rain coming all next week. We trimmed back some of the blowndown tules back from the boardwalk. The staff gauge read 54cm.

I downloaded met, cam, and USB GHG data. PARin had some gaps, although it was fine while we were there. All the wiring looked tight. Kyle cleaned flux and rad sensors and checked that the precip bucket funnel looked clean. She replaced the tiny zip tie that was holding the 7700 spray tubing to the nozzle. She made sure to seat the spray nozzle correctly back onto the 7700 spar.

I measured the surface water conductivity.
Surface, 729uS, 6.3C

The 7500 read: 433ppm CO2, 557mmol/m3 H2O, 10.1C, 102.1kPa, 93SS—95 after cleaning
The 7700 read: 2.4ppm CH4, 23RSSI—76 after cleaning

We left at 12:45 PST. I need to spend some time to secure the datalogger/mux better to the wooden backboard.
