Summary: Berms soft and muddy - no driving allowed. Tower got a bath. All good.

Wetland Construction
2013-11-21

We arrived around 12:00 PST. It was sunny, WINDY, and cold. We walked out to the site from the road because the new berms were very muddy and soft as a result of the recent rains. I checked the data while Laurie cleaned the instruments. The rains cleaned all the dirt and grime that had accumulated over the construction activities. The tower is squeaky clean for the move next week.

7500 readings:
CO2 = 16.6 mmol m-3 (16.7 after cleaning)
H2O = 300 mmol m-3 (260 after cleaning)
Diag: 248 (same after cleaning)
t = 17.8 C
p = 101.4 kPa
sos = 340.7 m s-1

7700 readings:
CH4: 2.04 ppm (1.96 ppm after cleaning)
RSSI: 14% (81% after cleaning)
Reservoir was 2/3 full refilled.

MET looked good.
Cleaned radiation sensors.
