Eden and I arrived at about 10:16 PDT. It was clear sunny and mild with a nice breeze. The forecast made it sound like it would be hot today but not so far. The water level was 33cm - somewhat lower. The water is still a little green.

Eden put the waders on and got in the water to take her algae samples.

I collected the met, flux and camera data. I refilled the wash reservoir. It was about half empty. Looked like bird poop had been mostly washed off the lower mirror. The tube protecting the 7700 temp sensor has broken off - I noticed this last time but failed to get on the todo list.
The 7500 read: 426.0ppm CO2, 705.2mmol/m3 H2O, 20.0C, 101.2kPa, 101.0SS - 102.6 after cleaning
The 7700 read: 2.06ppm CH4, 33.3RSSI - 70.9 after cleaning

I cleaned the radiometers - muddy bird feet

I did the salinity measurement
Surface, 1815uS, 20.0C

I scrubbed the staff gauge and chased a big spider out of the sonic range finder.

We went to the berm west of the tower for Eden to get her second sample. Eden will borrow the waders until the beginning of august.

We left at about 11:30 PDT
