West Pond
2013-04-26

We arrived around 13:20 PDT. It was sunny and warm. The inlet was not running so I called Jim and left a message. The water level was still moderately normal, though. The site is starting to green up. I checked the tower and swapped out the 7500 head while Sara and Wyatt went to collect water samples. I adjusted the 7550 clock to UTC time.

I removed 7500 head s/n 0065 and installed head s/n 2176
7500 readings before swap (s/n 0065):
CO2 = 385 ppm (397 after cleaning)
H2O = 560 mmol m-3 (490 after cleaning)
agc = 0.0
p = 102 kPa

7500 readings after swap (s/n 2176):
CO2 = 406 ppm
H2O = 470 mmol m-3
agc = 21.5
sos = 347 m s-1

7700 readings:
CH4 = 1.93 ppm
RSSI =28.5, bumped to 76 after cleaning

MET looked good.
