West Pond

Camilo, Ariane, and I arrived at 11:23 PDT. It was a sunny and breezy day with clear skies. The drill pad tower and equipment is back out on the old Twitchell Alfalfa field. There were sheep by the main gravel road. The water level was 53 cm.

Ariane cleaned flux and rad sensors. Camilo downloaded zcam data and swapped the desiccant in the miniDOT and water level sensor. I downloaded met, camera, USB GHG, and miniDOT data. The eosGP CO2 sensor sn GP20140026 was still reading 2% (5000 mV) when out of the water, so we removed it and brought it back to the lab for testing. The wash reservoir was 40% full; we topped it off. I forgot to bring the waders to take LAI by the zcam.

LI-7500 readings:
CO2 396ppm
H2O ???ppm
T 23.8C
P 101.4kPa
SS 99--> 100 after cleaning
LI7700 readings:
CH4 1.94ppm
RSSI 42--> 72 after cleaning

We walked on the north side of the wetland to try to find the outlet. We found two outlets, only about 20 m apart; both were accessible by boardwalks but you had to push reeds and willows out of your way. The eastern outlet had obvious water gushing into it. The western outlet was mostly still. Ariane marked the spots on her phone, and we left around 12:20 PDT.
