Summary: Regular data collection/cleaning, fluorometer disconnected--fixed, dead muskrat in water

2019-02-12
Mayberry

Kuno, Camilo, and I arrived at 10:52. It was cold, cloudy, and gray. There was a dead rodent (nutria?) with two prominent orange teeth in the water by the tower. The water level was 55 cm.

I collected met, camera, and USB GHG data. Kuno collected water samples for Isabel at 10:55. The wash reservoir was Â½ full; we refilled it. There has been no fluorometer data since 2019-01-31. We pulled the floating boom up and checked the cable. When we reconnected the cable, the fluorometer began recording data again. Camilo got in the water to get bubbles out.
