Summary: Put stakes at spot for new wetland tower. Data download. Adjusted 7700 washer settings to every 3 hours.

Wetland Construction
2013-11-06

We arrived around 13:15 PST. It was sunny with hazy high clouds, calm, and warm. We put stakes out at the spot for the new wetland tower after looking at the maps and simulated footprints yesterday. Per instructions from Jim, we left a map for him with the tower spot marked so that he could extend the berm for us to the tower site if possible. He said to call on Monday to chat more.

Back at the construction tower, we found the tower scaffold to be wobbly. One of the mid-tier legs was pull off the peg. Patty found some ubolts to push through the slots and lock the legs in place.


7500 readings:
CO2 = 15.1 mmol m-3 (16.9 after cleaning)
H2O = 700 mmol m-3 (335 after cleaning)
Diag: 249 (248 after cleaning)
t = 26.4 C
p = 102.4 kPa
sos = 344.3 m s-1

7700 readings:
CH4: 14 ppm (2.1 ppm after cleaning)
RSSI: 0% (74% after cleaning)
Reservoir was empty refilled. Also adjusted the settings to check and clean the mirror every 3 hours instead of every half hour.
