We arrived at 10:10. It was sunny and clear, a beautiful day in the Delta. There were some low clouds on the horizon. The cattails are chewed but still green.

The solar charge controller had ants, so we put in some mothballs. The site has started losing power some nights, so we should swap the solar panels or batteries.

Joe cleaned the fluorometer and emptied out the bubbles after re-deployment. Joe collected water samples near the fluorometer for Isabel at 10:45. He was already in the water so it was a bit mucky.

SWin data has been spiking. I moved SWin from channel 13 to 29 and updated the program, MB_Tule_20171117.CR1.

I downloaded USB, met, and camera data. When the Licor time was 10:34, I changed it to 10:39. We cleaned the EC/rad sensors and the outside of the camera enclosure. Wash reservoir was mostly full, and we topped it off.

LI-7500 readings:
CO2 411.4 ppm
H2O 443.5 mmol/m3
T 18.4 C
P 102.1 kPa
SS 103.8 --> 104 after cleaning

LI7700 readings:
CH4 1.95 ppm
RSSI 59.1 --> 75 after cleaning

The medium waders have leaks in the right knee and butt and need to be patched.

We left at 10:55.
