Summary: Standard fieldwork, midday water potential, could not collect tower met, floor met and soil moisture still one hour ahead, could not check on CR6 camera image collection.

I arrived about 11:30 with Siyan. There was some water in the puddles on the road. The trees here are fully leafed out now. The leaves seem bigger than usual but there are still bare twigs that have died back.

No computer at the tower so I collected data from each of the data loggers directly. I could not collect data from the tower met 23x. The RS232 port looked kind of corroded and did not work. There was a trail of copper corrosion down the front of the 23x and on to the bottom of the box. I could not see where it came from. The CSIO port had a connector in it and looked okay but I could not connect that way either. The data logger seems to be running, the mux is clicking and the key pad works. Restarting the data logger gave an error â€œE10 95 Low Batteryâ€.

The floor met and soil moister 23x still seems to have its clock one day ahead.

I also wanted to check on the CR6 that we installed to collect the camera images, but had several problems. I forgot the USB cable, I had an Ethernet switch but not a third Ethernet cable. I was going to unplug the camera and plug in the laptop, but then realized the computer didnâ€™t have the newest version of Loggernet needed for the CR6. And I did not have a micro SD card reader to check the CR6 data card. So crossing finger some more that images are getting recorded.

I serviced the zcams. Siyan did midday water potential.
