| DO Sensor | |||||
| 2021-11-04 | 931528 | miniDOT-usb | Installed | DO Sensor | Installed on a yellow chain near the SW corner of the platform. I think the sensor window is about 10cm above the ground |
| 2021-12-01 | 931528 | miniDOT-usb | Removed | DO Sensor | Removed from HS and brought back to the lab to swap its batteries. |
| 2021-12-02 | 931528 | miniDOT-usb | Installed | DO Sensor | I reinstalled the MiniDot that we removed yesterday due to dead batteries. |
| 2022-09-29 | 931528 | miniDOT-usb | Removed | DO Sensor | Removed from the HS channel and brought back to the lab for cleaning. There are calcareous deposits (some sort of encrusting worm) on and around the sensing foil. I soaked it in distilled white vinegar for 3 days. The deposits came off easily with a soft toothbrush. I rinsed the sensor well under DI water. |
| 2022-10-05 | 931528 | miniDOT-usb | Installed | DO Sensor | Installed after cleaning and measurement check in the lab. |
| 2024-09-26 | 931528 | miniDOT-usb | Adjusted | DO Sensor | Set clock in the field +1628 seconds (+27.1 minutes) to match internet time (used my cell phone hotspot to connect the laptop to the internet) |
