We arrived about 16:30 PST. High clouds, cool, and breezy. Field was drained but still mostly saturated. We collected data and cleaned the instruments.

7500 readings:
CO2 = 406 ppm (410 after cleaning)
H2O = 605 mmol m-3 (580 after cleaning)
signal strength = 88.6% (89.8% after cleaning)
t = 21.3 C
p = 101.7 kPa
sos = 345.4 m s-1

7700 readings:
CH4 = 2.0 ppm variable (stable after cleaning)
RSSI = 6% variable (69% after cleaning)
Reservoir was empty. Refilled to 2/3. Checked cleaning operation – no leaks.

Met looked good.
