Sherman Wetland
2021-09-02

Dennis and I arrived at about 10:00 PDT. Robert and Daphne joined us at about 11:30 after doing field work at Mayberry. It was sunny and warm with very hazy sky. Dennis said Purple Air reports put the AQI at about 100. This is the end â€“ we are completely removing this site today and moving it to the Gilbert Tract at Dutch Slough.

The staff gauge read 85cm.

I downloaded the eddy data and the met data then turned the power off.

No major problems taking things apart. There was a lot of rust on the bottom layer of the solar power scaffolding but it still seemed structurally sound. We managed to keep most of the met sensors connected to the datalogger boxes to keep rewiring to a minimum.

The aluminum flexible conduit protecting the soil temperature and heat flux wires was largely rotted through. And much of these lines were buried in nearly 20cm of cattail corms. I think we managed to get ground sensors out without damaging them but decided to take them back to the lab to replace the conduit and reposition the thermocouples.

We dropped the 7550 temperature dongle in the water but didn't realize it until we were setting up at the new site.

We had two small trucks with short beds, but managed to get everything packed and headed to Dutch Slough at about 3pm.
