Mayberry
2015-09-02

I arrived about 8:45 with Sara and Kyle. It was clear, sunny and warm with little to no wind. The water level was a little lower. The vegetation is still mostly green.

The 7700 read: 2.013ppm, 42.5RSSI â€“ 70.0 after cleaning
The 7500 read: 393.3ppm CO2, 630.1mmol/m3 H2O, 101.3SS, 22.58C, 101.2kPa

Kyle went into the water to retrieve the DO and CO2 sensors. The top miniDOT did not get turned on last time. We need a new copper screen for one of the MiniDots. The chain and clips seem to be rusting faster â€“ maybe higher salinity.

We reinstalled the LED circuit board. I fixed a bad solder joint on an inductor in the lab.

The Campbell DO sn DO-3 was reading INF on the data logger and 63mv with the voltmeter. It might have been out of range on the data logger. The mux might also be bad, it has another bad channel on it. We brought the DO for testing and service.

The auto cam collected photos this time, but they all seem to be of the inside of the enclosure. So, no GCC.
