Summary: Installed Global Water logger at Road Well, problems with new CF card for phenocam image collection, standard fieldwork, midday water potential

I arrived at about 11am with Siyan. It was clear, sunny and warm with a strong cool breeze from the west. Lots of flowers. The trees look fully leafed out. The ground is mostly dry.

I installed the repaired Global Water well sensor sn 57278 in the well next to the road. I was planning to mount it on the well pipe, but that pipe is really short. Instead I pounded in a fence post next to the well pad and mounted the box and solar panel on the post. The sensor/data logger is running on a small SLA battery and connected with the solar panel with the cheap solar controller sn 3317052234210. This controller is overkill for this system. I may be able to get a smaller panel and just connect it to the battery, but then a low voltage cutoff would be a good idea.

I collected all the data including the zcams. I tried replacing the CF card for the Stardot images with a brand new Verbatim card, but the CR1000 would not recognize the card. I ended up removing the current images from the SanDisk card and reinstalling it.

Siyan did the other fieldwork and midday water potential.
