|---|---|---|---|---|---|
| 6801 | 2024-08-02 | Factory none | Disposed | Disposed none | This chamber belonged to Eosense and they will not repair it. Disposed of. |
| 6800 | 2023-10-20 | Lab none | Shipped | Factory none | Returned to Eosense. This chamber originally belonged to Eosense - they will not repair it and it will be disposed of. |
| 6146 | 2023-01-10 | Lab none | Tested | Lab none | Tested in the lab and it turned on once we plugged in the power with its original cable, hallelujah. Data started being weird (spiky and/or 0) in mid-December when the field started flooding. However, during the performance check the CO2 concentrations were consistently all over the place, even after trying to reset it. This chamber probably needs to go back to the factory. |
| 6145 | 2023-01-03 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from BC and brought the chamber and cable back to the lab for testing. We found it floating in the water underneath the tower. The cable connector was underwater. |
| 5920 | 2022-07-14 | Lab none | Installed | Bouldin Corn Forced Diffusion C | Installed in the corn at BC. It's in the same location from where it was removed, one row west of the zcam. I connected to the FD chamber to confirm that it was running. |
| 5906 | 2022-07-11 | Lab none | Tested | Lab none | Plugged in and tested in the lab with another eosense cable. The chamber seems to be fine and the clock was still accurate, so I downloaded data from 2022-05-11 to 2022-06-08. I also ran a performance check which looked fine. I did not reset the reference.
Average Flux: -0.2, 0.05 STDEV Average ATM: 687.6ppm, 29.6C Average Soil: 677.7ppm, 29.8C |
| 5905 | 2022-06-08 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from field and brought back to the lab because even though the pump sounds like it's working, we haven't been able to connect to it for the past month |
| 5903 | 2022-02-17 | Lab none | Installed | Bouldin Corn Forced Diffusion C | Installed at BC under the tower |
| 5658 | 2022-01-11 | Lab none | Tested | Lab none | Ran for a few days and it had the expected zero flux. Did a performance check, which looked good. I did not reset the reference.
Average Flux: -0.1, 0.10 STDEV Average ATM: 586.4ppm, 27.5C Average Soil: 581.8ppm, 27.8C |
| 5651 | 2022-01-02 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from BC underneath the tower and brought back to the lab for testing. It was 1/2 submerged under water starting 2021-12-25, and Tyler put it on the lower boardwalk on 2021-12-29. |
| 5377 | 2021-07-20 | Bouldin Corn Forced Diffusion C | Maintenance | Bouldin Corn Forced Diffusion C | Performance check done. Referenced reset to 400ppm. Average Flux: -0.4, 0.09 STDEV Average ATM: 551.1ppm, 39.5C Average Soil: 534.8ppm, 39.5C Large difference between internal chambers. |
| 4797 | 2020-09-01 | Bouldin Corn Forced Diffusion C | Moved | Bouldin Corn Forced Diffusion C | Moved tower and soil sensors back from field in preparation for corn harvest. Chambers were reinstalled under the tower. |
| 4735 | 2020-05-19 | Bouldin Corn Forced Diffusion C | Moved | Bouldin Corn Forced Diffusion C | Moved back into the field from being under the scaffolding at the side of the field for tilling and planting. This chamber is still on a tall collar and is in normal density corn. |
| 4423 | 2020-04-17 | Bouldin Corn Forced Diffusion C | Moved | Bouldin Corn Forced Diffusion C | Removed from the corn field and installed under the tower because there will be tractor work on the field soon. |
| 4325 | 2020-01-07 | Lab none | Installed | Bouldin Corn Forced Diffusion C | Reinstalled at Bouldin Corn after being removed when the field was flooded. Installed near previous location on 12 inch collars. |
| 4734 | 2019-12-20 | Bouldin Corn Forced Diffusion C | Removed | Lab none | Removed from the field by Tyler due to being partially submerged by winter flooding. |
| 4729 | 2019-11-14 | Lab none | Installed | Bouldin Corn Forced Diffusion C | Installed in the corn field in the unharvested section |
