Summary: Regular data collection/cleaning, windy day, water samples for Isabel, water level is higher

2020-07-30
Mayberry

I arrived at 11:55 PDT. It was a warm and windy day with clear skies. The water level is higher and looks green. The water level was 59 cm. I collected water samples for Isabel at 11:00 PST.

The FD chamber membranes were submerged and mucky. I wiped the outside of the membranes, but the inside still needs cleaning. I also wiped down the fluorometer lenses, which were getting mucky, especially on the outside edges. I cleaned flux and rad sensors. There were spiderwebs on the sonic and covering the upper mirror of the 7700. I refilled the empty wash reservoir.

I downloaded met, camera, USB GHG, miniDOT and FD data. I donâ€™t remember if I cleared the FD memory or not. I changed the miniDOT battery and the miniDOT and water level desiccants.

LI-7500 readings:
CO2 395ppm
H2O 742ppm
T 21.6C
P 101.2kPa
SS 97--> 98 after cleaning
LI7700 readings:
CH4 1.9ppm
RSSI 33-->84 after cleaning

I left at 12:35 PDT. On the way out I stopped to pick blackberries at the Y-intersection where the roads to SW/MB diverge.

Muck on outside of fluorometer, most of which I could wipe off. The inside was mucky, too, but I couldn't reach it.
