East End
2017-06-05

I arrived about 12:55 with Daphne. It was warm and hazy with a light breeze. The cattails are growing, but the overall wetland does not look as green as previous years.

Before arriving at the main tower (and before stopping at West Pond) we retrieved the solar panels we left lying in the grass at the old rice site. We bolted the panels to a ground anchor at the closed canopy temporary tower site.

At the main tower,
The 7500 read: 420.5ppm CO2, 677.2mmol/m3, 29.6C, 101.1kPa, 97.3SS
The 7700 read: 2.02ppm CH4, 57.4RSSI â€“ 87.2 after cleaning
We refilled the wash reservoir and cleaned the rad sensors.

The water level around the tower was low and the Eosense water CO2 probe was exposed. I lowered it so that is was just barely in the water again.

We installed two SRS NDVI hemispherical sensors. These sensors needed their cables extended to reach the data logger. I splice on some extra wire. We installed sn 2046503390 in the incoming position and sn 2046503344 in the outgoing position. Initially we seemed to have a power short in one of the splices, but could not find anything obvious and after pulling things apart a bit the short disappeared.

The met program was updated after collecting the data.
