Summary: Regular data collection/cleaning, downloaded miniDOT data, fixed NDVI/PRI/WaterLevel

East End

We arrived at 13:25. It was cool, calm, and sunny, with some wispy clouds. The wetland was mostly brown.

Kyle cleaned the EC and radiation sensors and we refilled the empty wash reservoir. There were many fine spiderwebs everywhere.

The miniDOT was barely touching the water. We collected the data and lowered the probe farther into the water.

I collected met, camera, and USB GHG data. The LI-7550 "Eject" LED light was blinking slowly after I pressed Eject. According to the inside cover of the LI-7550, a slow blink indicates an error. I pulled the drive and reset the box. It doesn't look like we are missing any data files. The new USB starting logging fine.

NDVI, PRI, and Water Level had been NAN since previous field visit, and they are all SDI-12 sensors that should be wired to C7. I cycled the datalogger power, which did not fix the problem. An extra wire from the Eosense CO2 sensor was accidentally wired into the C7 port; the water level sensor was not connected at all. This wrong wire was preventing all data coming in on this channel. I fixed the wiring and the NDVI, PRI, and water level data looked ok.

I updated LI-7550 and LI-7700 time. The LI-7700 time was on automatic time, so I changed it to slave mode. When the 7550 time was 13:40:50, I changed it to 13:38:50. I reset the box, and the times look correct and synchronized.

We left at 13:55.
