West Pond

Robert, Ariane, and I arrived at 13:25. It was sunny and windy with blue skies. The inlet was on and gushing. The water level was 41 cm. We sprayed and knocked off more wasps nests before we left.

I downloaded met, USB GHG, and zcam photos. There were no photos again on the camera card, so we removed the camera to bring back and inspect in the lab. The zcam was a bit tilted, but we couldnâ€™t fix it because we now need boots to cross over to the boardwalk. The wash reservoir was mostly full; we topped it off. We cleaned flux and rad sensors and swapped the 7500 for calibration: sn 0418 came down and sn 75H-2182 went up. I uploaded a new configuration file, updated the pressure coefficients, and reset the box.

LI-7500 readings (sn 0418 --> sn 0418 clean --> sn 75H-2182):
CO2 385ppm --> 392 --> 390
H2O 745ppm --> 655 --> 694
T 29.5C --> 29.3 --> 292.9
P 101.2kPa --> 101.1 --> 101.1
SS 94 --> 96 --> 99
LI7700 readings:
CH4 1.95ppm
RSSI 48--> 73 after cleaning

We left at 13:45.
