Summary: Removed EXO interface and reconnected to CR6 - seems working, collected ADCP data, HYDROS wires broken again fixed again, reset Stardot clock, floating miniDot upside down

Gilbert Tract

I arrived at about 13:30 PDT. It was clear, sunny and breezy. Patty's crew was here yesterday and got most everything. The Azolla near the tower has come back to about half way fill the area Kuno cleared.

I went to the channel first. Here I removed the YSI interface box and connected the EXO directly to the CR6 again. After 5mins there were good looking numbers on the CR6.

While I was waiting on the CR6/EXO I downloaded the ADCP data. All seemed well there too. I stopped and restarted the logging to generate a new file.

Seems like Patty's crew downloaded the miniDot data but not the miniCH4 data, but I didn't check on the miniCH4 - next time.

I arrived at the tower about 14:00 PDT. Here I serviced the Song Meter. It only had one tiny file from the last field visit which I deleted. I replaced its batteries and it said it had good status.

I was going to download the met data because Patty's crew didn't have a working USB to serial cable but forgot to do it. I saw that the HYDROS21 and Air Temp were down again. Disconnecting the HYDROS SDI12 wire fixed the air temp. I didn't see any new damage to the HYDROS wires. The Campbell conductivity was chewed and removed last time so I used three of its conductors for the HYDROS. This seemed to work and we had both good air temp and water level again.

The Stardot clock has been offset for a couple weeks now. I collected the images since yesterday and then synced its clock with the computer. I hope I remembered to plug its Ethernet cable back into the data logger but maybe I didn't.

The floating miniDot was upside down with its sensor end in the air. I righted it and pushed it deeper into the foam so that the sensor end wants to stay down.

I left at about 15:00 PDT
