Summary: Water level has gone up slightly in the field, on-ramp to Hwy 12 is a muddy mess

Bouldin Corn

Arman and I arrived at 14:45 PST. There was a brief slowdown on Hwy 12 on the western half of Bouldin Island because of lane line painting. It was cool, still, and overcast. The gate was locked again. The water level has come up a little and there is about 5cm of standing water under the tower.

I downloaded met, cam, USB GHG, and PA data. The reservoir was 70% full. Arman refilled it and cleaned flux and rad sensors.

The 7500 read: 455ppm CO2, 515mmol/m3 H2O, 13.4C, 101.8kPa, 99SS—100 after cleaning
The 7700 read: 2.4ppm CH4, 45RSSI – 78 after cleaning

We left at 15:00 PST. As Joe said in the previous field note, the on-ramp to Hwy 12-E is a muddy mess. We had a large truck but no 4WD today, so I sped through it all and skidded briefly at the end. "Slick as snot," as Dennis would say. We had to wait a while to actually merge onto the highway--the slowdown meant the vehicles were going more slowly and there were fewer gaps in the traffic. Another option is to go to alfalfa first next time, use the levee road to get back on Hwy 12 to access corn, and then leave Bouldin Island by merging onto westbound 12. That on-ramp on the north side of the highway seems to be in better shape.
