Mayberry

Kyle, Camilo, and I arrived at 14:50. It was mostly overcast with big fluffy cumulus clouds, mild and calm. There were many mosquitoes hovering around us. We can see patches of green tules, and the wetland is about 10% green. The weeds were a meter tall; Kyle trimmed a path between the car and the tower.

The wash reservoir was Â¼ empty; we refilled it. We also trimmed the screw that was sticking out of the boardwalk. The water level was 58 cm. The Nikon camera was out of batteries so we did not take a reference GCC photo.

I downloaded met, camera, USB GHG, and miniDOT data. I replaced the SD card for the top minidot since it had been missing files despite recent battery changes; however from the equipment history we just swapped the card 2018-05-31, so the problem may be with the sensor, not with the card. We should keep an eye on it. The other minidot looks like it still has the original SD card from 2014.

Camilo cleaned flux and rad sensors. Kyle disconnected the fluorometer and cleaned it. We made sure it was sending messages to the datalogger after we reconnected it. I collected water samples for Isabel at 14:05 PST.

Camilo walked around in the water with a funnel (precipitation bucket funnel) and a lighter to try to capture enough methane to burn.
