Battery Bank
2024-09-26 BB-GT BB-Fab Installed none Joe installed four new batteries with improved security. The batteries are secured with a metal bar to the box/boardwalk with all-thread on each side of the bar. The all-thread is attached to the bar with security nuts. The ActionPacker box has a lock on it and it's now on a lower level of the scaffolding so it's less visible from the road.
Camera
2021-09-02 0030F4D214A5 SD130BN Moved Camera Moved from SW to GT with the decomissioning of SW and the beginning of GT
CH4 Probe
2025-01-15 38-573-25 MiniCH4 Installed none Installed on a floating frame with an external battery pack on top so that the CH4 probe is horizontal just below the surface and the battery pack is horizontal just above the water. It's connected to the boardwalk with a yellow plastic chain. Should be collecting an average of 5 readings every 15 minutes.
CO2 Probe
2021-09-09 GP20200089 GP-001 Installed CO2 Probe Installed at Gilbert Tract but the cable was too short - not hooked up until 2021-09-15
2023-03-23 GP20200089 GP-001 Removed CO2 Probe Removed from Gilbert Tract (was installed by the staff gauge) and brought back to the lab for testing. I think this sensor is dead.
2023-03-23 GP20210002 GP-001 Installed CO2 Probe Installed at Gilbert Tract on a post (just off the far end of the boardwalk) with the other water quality sensors. Should be at the same height as before (about 5cm above the soil)

DO Sensor
2021-09-09 906606 miniDOT-usb Installed DO Sensor Installed at Gilbert Tract on a yellow chain that just barely meets the water. When the site becomes tidal we will have to have a longer chain or more likely a boardwalk to reach deeper water.
2022-05-06 1221 miniDOT Installed none Mckenna from USGS installed this at the GT breach site next to the other USGS water sensors in the channel. They plan to service the sensors every 3 months.
2024-01-18 180871 miniDOT-usb Installed DO Sensor Channel Installed on the back of the ADCP mount to measure the channel's DO. Channel DO was previously measured with miniDOT sn 1221 co-located with the USGS EXO, but that miniDOT stopped working last August.
2024-07-23 1221 miniDOT Removed Returned to us from USGS. Was co-located with their EXO in the Gilbert Tract channel, but the data wasn't good since August 2023.
2024-09-19 180871 miniDOT-usb Moved none Temporarily moved from the Gilbert Tract channel to Robert's "upland" thermocouple profiles west of the tower
2024-09-19 899502 miniDOT-usb Moved none Temporarily moved from the Mayberry floating boom to Gilbert Tract to Robert's "northside" thermocouple profiles west of the tower

There was an issue with the dew point generator where it was producing a dewpoint ~16C when the temp switch was set to 20.00C. I calibrated the H2O span the next day on 9/21. We fixed the problem by adding more water in the condenser block on the back of the machine. The water level looked ok while the cap was on and the machine was running, but once I turned the machine off and took the cap off, the water level dropped to below the "Min" line. After I added water and turned it back on, the dewpoint generator got to a reasonable dewpoint and it seemed stable.

The zero air tank pressure may have been >100psi, but the regulator was wonky. Zero was stable for 2min after applying zero. Swapped out the desiccant one for one with new drierite after calibration. I didn't flush out the headspace because I wanted to preserve the zero air for more calibrations that day.

Water Level
2021-09-02 20010026 CS450 Moved Water Level Moved from SW to GT with the decomissioning of SW and the beginning of GT. Not installed until 09/09
2021-12-15 1782303006 CTD-10 Installed none Installed at GT in the wetland. it is just laying on its side on the ground for now. We will hang it properly after installing a boardwalk on site.
2022-02-02 20010026 CS450 Removed Water Level Removed from Gilbert Tract as its measurements are now redundant with the HYDROS21 water level sensor.
2022-08-24 1782303006 CTD-10 Removed Removed from GT and brought back to the lab. The depth data is bad but temperature and conductivity seemed reasonable.
2022-10-19 H21G20001202 HYDROS21 Installed Water Level Installed at GT off of the boardwalk where it is co-located with the eosGP and Campbell conductivity sensor. When the staff gauge read 21cm, the bottom of the sensors was 19cm below the water.
2024-04-16 H21G200002433 HYDROS21 Moved Water Level Boardwalk Removed for temporary use at GT, EXO should have the same data.
2024-04-16 H21G20001202 HYDROS21 Removed Water Level Removed from GT and brought back to the lab. Its cable was chewed and totally broken in at least 2 places.
2024-08-29 H21G200002433 HYDROS21 Removed Water Level Boardwalk Removed from GT (off of boardwalk) because water level data was not working. Brought back to the lab for further testing.
2024-10-10 H21G00003238 HYDROS21 Installed Water Level Boardwalk Installed on the fence post just off of the boardwalk walkway. It is co-located with the Campbell conductivity sensor.
Weather Station
2021-09-15 A001911 Mark I Installed Weather Station Installed on the radiation boom pointing south
2022-12-13 A001911 Mark I Removed Weather Station Removed from the GT tower. This unit has not be sending reliable data for a long time and Arable no longer supports this model. To be disposed of.
2024-03-07 D006946 Mark 3 Installed Weather Station Installed at Gilbert Tract on the radiometer boom.
Wiper
2024-08-16 24F104086 EXO Central Wiper Installed none Installed with EXO3s in Gilbert Tract channel, co-located with the ADCP and channel miniDOT
2024-10-17 24F104086 EXO Central Wiper Removed Removed from GT channel and brought back to the lab for calibration
2024-10-23 24F104086 EXO Central Wiper Installed none Installed in the GT channel
