I arrived about 11:30 with Siyan. It was clear, sunny and cool with little to no wind. The ground looks a little more damp and green, but still worked over by the cows.

The tram had quit about half way down the track where it had derailed. I reset it and it ran a couple of times while we were there.

We reinstalled the CO2 probes. Six of the original probes went back in the ground in tow profiles of -2, -4 and -8cm in the open and under the trees. We removed the fourth transmitter form each box for a third (location yet to be determined) profile under the trees. One of the freshly calibrated probes (sn X3830001) did not work in the field. We swapped it for sn Z2720012.

I removed resistors from the transmitters and installed the resistors from the lab calibration.

The probes in the open were installed to the north of the box. The tree probes were moved away from the base of the tree and into and area between several trees to the northeast of the box. I had to move the cow fence a little.
