Summary: Fieldwork with help from my family, pond is only half full, tree slowly putting on leaves, troubleshooting COSMOS - maybe working again, power outage at soil co2 - fixed

Kyoko, Hisashi and I arrived at about 11:45. It was partly cloudy, cool in the shadows and warm in the sun. There has been some rain and there are puddles in the road, but the pond is still only half full. The trees are still putting on leaves slowly â€“ some tree are almost fully leafed out and others barely have any. We met Rob on the way out mending fences. He said his land is 680acres. He also said folks in the area are still struggling with wild pigs. He killed one that was about 170 pounds but not too good to eat â€“ too tough. He asked if I knew anyone that had COVID-19. At this time, I donâ€™t.

I collected the data, serviced and z-cams, and read the dendrometers. Hisashi and Kyoko did the soil moisture and the well measurements.
The Tower read: 404.9ppm CO2, 327.3mmol/m3 H2O, 98.9kPa, 14.6C, 101.1SS
The Floor read: 420.4ppm CO2, 447.7mmol/m3 H2O, 99.0kPa, 16.7C, 102.8SS

The power was out at the soil CO2 system. I stepped on some wires last time out and apparently pulled the ground wire from the batteries loose from the solar controller. This system needs a complete overhaul. I restored the power, but no soil CO2 data or FD Chamber data for the last three weeks.

The lithium power pack at the road well was down to three of five power lights and the Global Water sensor was reporting 10.6V. I swapped the power pack out with one of our new larger packs. The sensor was reading about 0.5ft of water.

The COSMOS system has not been reporting data since Dennis and I messed with it back on June 13th. I checked on it and didnâ€™t see anything wrong. There were about 2000 files on its SD card but all small so plenty of space left. I copied the files off for later, put the card back and restarted the system. Just before leaving I talk to a technician (Gary Womack ) who said he saw a couple of messages from the system. So maybe itâ€™s working again.

I realigned the IRTs pointed at the tree trunk slightly. The IRT system at the little tree hasnâ€™t connected for about 10 days but I didnâ€™t notice this until I was back in the lab. It doesnâ€™t look like a power problem so probably the data is okay on the CR1000.

We left about 14:45
