East End

Joe, Camilo, and I arrived at 12:55 PST. It was a cold and foggy day with a little breeze. The wetland was all brown, but there were some green tules on the other side of the gravel road. The water level was 31 cm.

Joe and I downloaded met, camera, USB, and miniDOT data. Joe swapped desiccants for the water level sensor and the miniDOT and greased the o-ring. There was a 7550 time sync error; I confirmed that the 7550 was on auto and the 7700 was on slave. I reset the 7550, which resolved the time error. I changed the 7700 wash spin from 10 sec to 30 sec to allow enough time to spin away the spray water (7700 wash spray remained at 10 sec). The wash reservoir was mostly empty; we refilled it. Camilo cleaned flux and rad sensors.

The bottom boardwalk wood should be replaced: 81" x 18-¾", 5/16 all thread.

Back in the lab, there were no camera photos after 2019-12-22. Maybe there was some power issue?
