Summary: Added third FD chamber, standard fieldwork, collected pond data

Vaira
2017-10-25

Siyan and I arrived at 10:30am. It was warm and sunny with little to no wind. There was a little bit of rain in the wee hours of the morning of the 20th but the ground surface is still dry. The dead grass may be a bit less brittle due to the rain.

I installed FD chamber sn 20160004 near the north soil co2 profile. It started right up with no changes to the hardware. Seems it was just too warm to start last time. The other chambers seem to be running just fine. I collected data from all the chambers but did not clear the memories.

Siyan collected the Licor GHG data. I collected the met and camera images. The camera clock got reset to the year 2000. When it read 2000-01-07 13:51, I reset it to 2017-10-25-09:04. I will have to fix the images recorded with the wrong times.

Siyan cleaned the radiometers, did spectral measurements and did the soil moisture measurements. The biomass fence has been moved. The moisture probe is now in the southeast corner.

We went to the pond to collect the data. The water level is now below the lowest mark on the staff gauges, but not below the pressure sensor.
