We arrived at approximately 13:00 PST. It was cloudy with a mild breeze, and chilly (~10 °C). The field remains flooded with no visible change from last visit. I cleaned the instruments (incl. rad sensors) and swapped in a new radiation shield for the Vaisala T/RH sensor (dead fan) while Laurie downloaded the data and autocam pics.

Current 7500 readings:
CO2 = 405 ppm
H2O = 392 mmol m-3
P = 101.6 kPa
agc = 43.8 (37.5 after cleaning)

7700 readings:
CH4 = 2.35 ppm
RSSI = 39 (bumped to 65 after cleaning)
sos: 339 m/s
Topped off fluid reservoir
