| 6648 | 2024-04-10 | Lab none | Installed | Hill Slough Turbidity | Reinstalled at the HS channel after regular lab cleaning and calibration |

EXO sn 22C103416 EXO/Sensor Firmware: 1.0.86/3.0.4 ,Standard,PreCal,PostCal,RawValue,Temp Pt1,0.00 FNU,-2.02 FNU,0.00 FNU,0.00 FNU,22.248 °C Pt2,124.00 FNU,122.66 FNU,124.00 FNU,0.00 FNU,21.856 °C Pt3,1010.00 FNU, 1024.22 FNU, 1010.01 FNU, 0.00 FNU, 21.956 °C Note: 0 FNU point done with MQ water (stored in plastic bottle at room temeprature since 2024-02-01). I also tested it with DI water from the lab tap; pre-cal value was -2.14 FNU, almost the same as the MQ water. In the future I think using DI water from the lab tap is good enough for the calibration. |
| 6640 | 2024-04-04 | Hill Slough Turbidity | Removed | Lab none | Removed from the Hill Slough channel and brought back to the lab for calibration (and to install the new auto wiper that arrived) |
| 6618 | 2024-01-25 | Lab none | Installed | Hill Slough Turbidity | Installed in the Hill Slough channel after calibration |
| 6548 | 2024-01-22 | Lab none | Calibration | Lab none | Turbidity (FNU), Last cal: 2023-10-16
EXO sn 22C103416 EXO/Sensor Firmware: 1.0.86/3.0.4 ,Standard,PreCal,PostCal,RawValue,Temp Pt1,0.00 FNU,3.85 FNU,0.00 FNU,0.00 FNU,21.571 °C Pt2,124.00 FNU,122.47 FNU,124.00 FNU,0.00 FNU,20.745 °C Pt3,1010.00 FNU, 959.99 FNU, 1010.00 FNU, 0.00 FNU, 20.651 °C Note: Used the lab's DI water for zero point for this and previous calibrations. I'll try to get some miliQ water for future calibrations since this zero point had a larger than usual offset. Probably doesn't affect our data too much since our turbidity is usually >50 FNU. |
| 6543 | 2024-01-18 | Hill Slough Turbidity | Removed | Lab none | Removed from HS channel and brought back to the lab for routine calibration |
| 6447 | 2023-10-18 | Lab none | Installed | Hill Slough Turbidity | Installed in the Hill Slough channel after calibration in the lab. The whole sonde was raised about 20cm to keep it out of the mud. |
| 6438 | 2023-10-11 | Hill Slough Turbidity | Removed | Lab none | Removed for inspection in the lab because turbidy/fDOM/ph/ORP look weird |
| 6391 | 2023-08-24 | Lab none | Installed | Hill Slough Turbidity | Reinstalled after quarterly cleaning and calibration |
| 6375 | 2023-08-17 | Lab none | Calibration | Lab none | Turbidity (FNU), Last cal: 5/5/2023 13:43:44 EXO sn 22C103416 EXO/Sensor Firmware: 1.0.86/3.0.4 ,Standard,PreCal,PostCal,RawValue,Temp Pt1,0.00 FNU,-0.44 FNU,0.00 FNU,0.00 FNU,24.534 °C Pt2,124.00 FNU,124.94 FNU,124.00 FNU,0.00 FNU,23.738 °C Pt3,1010.00 FNU, 1017.94 FNU, 1010.00 FNU, 0.00 FNU, 23.875 °C Note: 0 point was not steady until checked for and wiped off small bubbles from sensor face |
| 6367 | 2023-05-09 | Lab none | Installed | Hill Slough Turbidity | Installed in the channel at Hill Slough (same height as before) after calibration |
| 6276 | 2023-04-25 | Hill Slough Turbidity | Removed | Lab none | Removed from HS channel for routine calibration |
| 6152 | 2023-01-06 | Lab none | Installed | Hill Slough Turbidity | Installed in the channel at Hill Slough (same height as before) after calibrating in the lab yesterday. |
| 6147 | 2023-01-03 | Hill Slough Turbidity | Removed | Lab none | Removed from Hill Slough channel and brought back to the lab for calibration. |
| 6013 | 2022-09-29 | Lab none | Installed | Hill Slough Turbidity Channel | Installed as part of the EXO2 sonde in the channel at Hill Slough. |
| 6055 | 2022-09-23 | Lab none | Calibration | Lab none | Turbidity (FNU), Last cal: Unknown EXO sn 22C103416 EXO/Sensor Firmware: 1.0.86/3.0.4 ,Standard,PreCal,PostCal,RawValue,Temp Pt1,0.00 FNU,-0.19 FNU,0.00 FNU,0.00 FNU,24.000 °C Pt2,124.00 FNU,124.85 FNU,124.00 FNU,0.00 FNU,24.000 °C |
| 6010 | 2022-09-16 | Hill Slough Turbidity Channel | Removed | Lab none | Removed as part of the EXO2 sonde deployed in the channel at HS. Brought back to the lab for cleaning and calibration. |
| 6007 | 2022-07-13 | Lab none | Installed | Hill Slough Turbidity Channel | Installed as part of the EXO2 sonde at HS in the channel off of the boardwalk, about 30m east of the tower. |
