West Pond
2013-07-31

We arrived around 13:30 PDT. It was sunny, breezy, and warm (25 C). They buried the inflatable pipe on the road leading to the site, a wise decision.

There was no water under the tower again when we arrived, and too little water to take water samples. There was more ant activity in the 7550 box, they chewed through the latex glove I placed to add pressure to the door seal. I blew as many as I could out of the box with the compressed air can, and added quite a bit of silicone to bolster the door seal. We shall see if it was enough.

Otherwise, all was fine at the site. I confirmed that the 7700 was set to update at 20 Hz (in the settings of the 7700 program).

7500 readings:
CO2 = 387 ppm (after cleaning)
H2O = 658 mmol m-3 (after cleaning)
signal strength = 87.35% (after cleaning)
t = 25.5 C
p = 101.3 kPa
sos = 349.4 m s-1

7700 readings:
CH4 = 1.9 ppm (after cleaning)
RSSI = 75 after cleaning
Reservoir was full.

MET looked good aside from readings indicative of no water under the tower.
