West Pond

Kuno, Jiangong, and I arrived at 12:07. It was mostly sunny, but with low fog/clouds to the south. The black fungus that had been growing on our boardwalk had dehydrated and shrunk; it now looks like black liquid electrical tape. There was no standing water on top of the soil; the eosGP CO2 and miniDOT sensors were in the air. The water level was 15 cm (5 cm below soil level).

Kuno downloaded met, camera, USB GHG, and miniDOT data. He also changed CR1000 sn 47109 Pakbus address from 1 to 9. Jiangong cleaned the flux and rad sensors. We had previously put a computer fan in the camera enclosure to reduce condensation; I changed the fan position from behind the camera to between the camera and the enclosure window.

LI-7500 readings:
CO2 424ppm
H2O 610ppm
T 18.8C
P 101.3kPa
SS 84--> 86

LI7700 readings:

RSSI 53 --> >70 (forgot to write after cleaning)

We left at 12:40 and turned the water inlet on a little on our way out.
