| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 6795 | 2024-05-15 | Lab none | Installed | Tonzi-SoilCO2 Forced Diffusion Open | Installed 1.5m to the west of the original location with a longer cable to the OSU box. |
| 6722 | 2024-05-08 | Tonzi-SoilCO2 Forced Diffusion Open | Removed | Lab none | Removed from the Open location at Tonzi. Cows ate all the power infrastructure and its cable might be slightly chewed. |
| 6212 | 2023-03-01 | Lab none | Installed | Tonzi-SoilCO2 Forced Diffusion Open | Installed in the open location fresh from factory repair. |
| 6201 | 2023-02-28 | Factory none | Returned | Lab none | Returned after repair at Eosense: CO2 sensor replaced, concentration calibration and flux calibration. |
| 6200 | 2022-08-23 | Lab none | Shipped | Factory none | Shipped to Eosense on RMA220809 for repair |
| 5926 | 2022-08-03 | Lab none | Tested | Lab none | I did two performance tests on this chamber. The CO2 for bother chambers is reading negative -200 to -300 ppm. I tried to reset it to 400ppm but it didn't seem to work. |
| 5925 | 2022-07-19 | Tonzi-SoilCO2 Forced Diffusion Open | Removed | Lab none | It was reading mostly zeros (with large positive and negative spikes) in the last few weeks, so it was removed and brought back to the lab for testing. |
| 5445 | 2021-09-01 | Lab none | Installed | Tonzi-SoilCO2 Forced Diffusion Open | Installed at Tonzi-SoilCO2 to replace sn FD20180026 for testing it the lab and possible repair. |
| 5403 | 2021-08-04 | Lab none | Maintenance | Lab none | This chamber was removed from the Mayberry boom because its readings looked bad. In the lab I cleaned it up. There are what look like tooth or claw marks on most of the filter windows but no breaks. The initial performance check had the first of the five measurement way off which skewed everything, but its concentrations were about -140ppm. I reset the concentrations to 400ppm and did a second performance check. The second check was much better: Average Flux: -0.1, 0.05 STDEV Average ATM: 378.1ppm, 32.0C Average Soil: 374.8ppm, 32.0C I reset the baseline CO2 concentration to 400ppm again. I think this chamber can be swapped back into the field as needed. |
| 5401 | 2021-07-21 | Mayberry Forced Diffusion Boom | Removed | Lab none | Removed from Mayberry because the numbers looked bad. Replaced by sn FD20180047. |
| 4718 | 2020-08-28 | Lab none | Installed | Mayberry none | Installed on MB floating boom with a long black collar |
| 5375 | 2020-08-11 | Mayberry | Removed | Lab none | Removed from MB for a thorough cleaning |
| 4495 | 2020-05-21 | Lab none | Installed | Mayberry none | Installed on the Mayberry floating boom. |
