Summary: Regular data collection/cleaning, water level still low, water samples for Isabel, adjusted level of floating bloom

Mayberry

Alex and I arrived at 10:45. It was a breezy and mostly overcast day with mild temperatures. Some of the reeds (phragmites?) by the grass road had been blown down by last weekâ€™s wind. The mud level was 12 cm; the water level was still really low and far below the mud surface.

Alex collected water samples for Isabel at 9:55 PST. He cleaned flux and rad sensors and cleaned the solar panels. We topped off the wash reservoir; there were many wasps inside. I downloaded met, camera, USB GHG, and miniDOT data. We swapped the desiccant for the water level sensor and miniDOT.

The fluorometer lenses looked clean, although there was lots of algae on the brushes and around the lenses. After I lowered the boom, the fluorometer was just touching the water, so I raised the boom up again and lowered the fluorometer chain. Then, the fluorometer looked like it was too low and touching the mud, so I raised up the whole boom by 2 links.
