Summary: Regular data collection/cleaning, serviced water sensors, collected water samples for Isabel, still losing power nightly

We arrived at 9:45. It was foggy and cool. Looks like we are still losing power at night. From the charge controller, Batt V = 14.5, Solar in = 3.6 A, Load out = 1.6 A.

Kyle collected 3 water samples for Isabel at 9:50. We collected the minidot data. The top minidot was off, so there was no data. We need to bring 2 fresh desiccants for the minidots.

Kyle removed the fluorometer from the boom, screwed off the cap and cable, and cleaned the fluorometer brushes with a green scrub pad and DI water; the brushes were dirty and mucky, but the sensor windows looked clean. After we finished servicing the water sensors, Kyle got in the water to get all bubbles out of the fluoromter.

Sam cleaned the flux and rad sensors. The 7500 had too much water on it to get initial CO2/H2O sensors.

LI-7500 readings:
CO2 **.* ppm --> 464 after cleaning
H2O **.* ppm --> 550 after cleaning
T 12.8 C --> 12.5 after cleaning
P 102.3 kPa --> 102.4 after cleaning
SS 0 --> 100 after cleaning

LI7700 readings:
CH4 2.6 ppm --> 2.6 after cleaning
RSSI 56 --> 76 after cleaning

We left at 10:10.
