| DO Sensor | |||||
| 2014-09-25 | 1219 | miniDOT | Installed | DO Sensor B | Installed at West Pond in a profile at 7.5cm above soil in water column. |
| 2014-10-09 | 1219 | miniDOT | Removed | DO Sensor B | Removed from West Pond for installation at Mayberry where a longer profile is possible. |
| 2014-09-25 | 1220 | miniDOT | Installed | DO Sensor A | Installed at West Pond in a profile at 13cm above soil in water column. |
| 2014-10-09 | 1220 | miniDOT | Removed | DO Sensor A | Removed from West Pond for installation at Mayberry where a longer profile is possible. |
| 2014-09-25 | 1221 | miniDOT | Installed | DO Sensor C | Installed at West Pond in a profile at 2cm above soil in water column. |
| 2014-10-09 | 1221 | miniDOT | Removed | DO Sensor C | Removed from West Pond for installation at Mayberry where a longer profile is possible. |
| 2020-08-21 | 180871 | miniDOT-usb | Installed | none | Installed at WP, hanging on a yellow plastic chain on the east side of the tower between the tower and the wooden deck. The sensor is currently in air. |
| 2024-01-11 | 180871 | miniDOT-usb | Removed | DO Sensor A | Removed from WP with site decommissioning |
| 2018-05-31 | 899502 | miniDOT-usb | Installed | DO Sensor A | Installed at WP tower, tied with a string on the NW corner of the the scaffolding. |
| 2020-01-07 | 899502 | miniDOT-usb | Removed | DO Sensor A | Removed from WP and brought back to the lab because of low water levels. |
| 2020-05-19 | 899502 | miniDOT-usb | Installed | DO Sensor A | Installed on the east side of the tower, between the scaffolding and the wooden platform. |
| 2020-07-21 | 899502 | miniDOT-usb | Removed | none | Removed from WP tower and loaned to Ariane to bury underground in WP. There's not much water at the WP tower anyways, and Ariane is planning on draining it the following week. |
| 2021-06-09 | 899502 | miniDOT-usb | Removed | Removed from WP and brought back to the lab for data download. This sensor had been installed in the mud near 0.5 footprint | |
| 2012-04-17 | DO-04 | DO6400/T | Installed | DO Sensor Lower | Installed on post northwest of scaffolding at west pilot pond. Not running because of forgotten power connector. |
| 2012-08-02 | DO-04 | DO6400/T | Serviced | DO Sensor Lower | DO-04 was serviced in the field due to unexpectedly low readings. The electrolyte was replaced. |
| 2012-08-16 | DO-04 | DO6400/T | Serviced | DO Sensor Lower | DO-04 was serviced in the field due to continued unexpectedly low readings. The inside was rinsed with vinegar and scrubbed with a tooth brush. The electrolyte was replaced. |
| 2012-08-30 | DO-04 | DO6400/T | Removed | DO Sensor Lower | DO-04 was removed from the water at West Pond due to continued low readings. The sensor will be checked in the lab and reinstalled. |
| 2012-09-06 | DO-04 | DO6400/T | Installed | DO Sensor Lower | DO-04 was resintalled in the deeper location at West Pond. The lab check went fine and it has been decided that the low values are correct and that the water is just very oxygen poor. |
| 2013-01-03 | DO-04 | DO6400/T | Moved | 0 | This sensor was moved from the upper location at West Pond to near the well at the Twitchell Rice. The sensor was left laying sideways on the bottom of the flooded field. |
| 2012-04-17 | DO-05 | DO6400/T | Installed | DO Sensor Upper | Installed on post northwest of scaffolding at west pilot pond. Not running because of forgotten power connector. |
| 2012-08-02 | DO-05 | DO6400/T | Serviced | DO Sensor Upper | DO-05 was serviced in the field due to unexpectedly low readings. The electrolyte was replaced. |
| 2012-08-16 | DO-05 | DO6400/T | Serviced | DO Sensor Upper | DO-05 was serviced in the field due to continued unexpectedly low readings. The inside was rinsed with vinegar and scrubbed with a tooth brush. The electrolyte was replaced. |
| 2012-08-30 | DO-05 | DO6400/T | Removed | DO Sensor Upper | DO-05 was removed from the water at West Pond due to continued low readings. The sensor will be checked in the lab and reinstalled. |
| 2012-09-06 | DO-05 | DO6400/T | Installed | DO Sensor Upper | DO-05 was resintalled in the shallow location at West Pond. The lab check went fine and it has been decided that the low values are correct and that the water is just very oxygen poor. |
| 2024-05-01 | DO-05 | DO6400/T | Removed | DO Sensor Upper | Removed with the decommissioning of the site. Has been non-functional for a long long time. |
