Mayberry

Joe, Kuno, and I arrived at 14:05 PST. It was warm and breezy. The staff gauge read 50cm.

At Mayberry the fifth event of the 2024 Biomet Olympic hexathalon was held. Here Daphne and Joe competed in the mixed relay sipathon. Joe made a solid start clearing the first ten sippers but his enthusiasm was clearly waning when he passed the conductivity meter to Daphne. Daphne made quick work of the last five sippers and earned some extra style points with her triple-double valve technique.

I downloaded met, cam, USB GHG, and miniDOT data. I did not change the miniDOT desiccant because we didn't have any more dry minipaks. The wash reservoir was mostly full and Joe topped it off. There was a large yellow garden spider in the reeds between the boardwalk and the tower.

We lowered the eddy post and Kuno cleaned flux and rad sensors. We calibrated the 7700. The offsets were small and we replaced the hat and spray nozzle after the calibration. I checked that the 7700 was connected and that the USB was logging after the calibration. We moved the eddy post back up to its original position after calibration.

Joe measured the porewater conductivity for the veg-black and veg-red profiles by the boardwalk. I measured the porewater conductivity for the veg-blue profile. We rinsed the syringe with the initial 10ml of sample and measured the subsequent 20-30ml of sample.

Joe cut back some of the reeds that were growing across the boardwalk.

The 7500 read: 409ppm CO2, 657mol/m3 H2O, 32.9C, 100.4kPa, 103SS – 105 after cleaning
The 7700 read: 2.0ppm CH4, 51RSSI – 86 after cleaning
I forgot to write down the 7700 numbers after calibration.

Veg-black-black,,, 10cc rinse then only 10cc more so not enough to measure
Veg-black-red,,, none pushed some air and saw bubbles but still none
Veg-black-yellow,,, none pushed some air and saw bubbles but still none
