East End

Robert and I arrived around 16:45 PST. We are servicing Twitchell/Bouldin Islands after helping with Kuno’s chamber/soil sampling campaign in the first part of the day. It was partly cloudy, cold, and the sun was setting. We could hear an owl hooting off in the distance. The staff gauge read 54cm.

A sheep fence was up just south of the tower. Jaime opened it for us after hearding a group of sheep to the side.

I downloaded met, cam, and USB GHG data. The miniDOT is due today but I didn’t download it. It was getting late and I decided it could wait. There’s plenty of storage in the miniDOT.

Robert cleaned flux and rad sensors. The reservoir was full so we didn’t refill it.

The 7500 read: 422ppm CO2, 546mmol/m3 H2O, 11.2C, 102.1kPa, 95SS – forgot to write after cleaning
The 7700 read: 2.05ppm CH4, 60RSSI – 82 after cleaning

We left at 17:01 PST.
