Twitchell Rice
2014-11-11

We arrived around 12:15 PST. Clouds were clearing and it was cool with a light wind. Collected data. Pulled SHF #1 for fixing in lab. Added DO probe (read 30.69 in air). There were a lot of spider webs in the analyzer paths. The 7700 reservoir was almost empty – refilled.


Readings:
CO2 = 375.5 ppm (404 after cleaning)
H2O = 605 mmol m-3 (545 after cleaning)
signal strength = 81.75% (89.91 after cleaning)
p = 101.7 kPa
t = 19.3 C
sos: 344.7 m s-1
CH4 = 1.9 ppm
RSSI = 41% (67% after cleaning)

Met looked good.
