Rec No.	Date	Loc From	Title	Loc To	Notes
5429	2021-08-26	Lab none	Notes	Lab none	Partly cleaned this sensor and tried to take the cable off. However, the connector at the top of the sensor twists loose from the body of the sensor so I don't think it's worth keeping. I'm not sure if the connector was already loose, or if I loosened it trying to table the cable off.
5237	2021-04-13	Lab none	Tested	Lab none	Tested in the lab and the CO2 signal responded to my breath. I'll keep it running for a while and see if the noise comes back; maybe it just needs a new connector/cable. This sensor needs a scrubbing.
5208	2021-03-16	Mayberry CO2 Probe A	Removed	Lab none	Removed from MB b/c it was sporadically reading noise. it was replaced by sn GP20150111.
4410	2017-05-25	Mayberry CO2 Probe A	Moved	Mayberry CO2 Probe A	Moved to floating boom. Depth is ~-15cm below water level. Co-located with sn GP20150111 (which was removed 2017-08-16).
4409	2017-05-10	Mayberry CO2 Probe A	Moved	Mayberry CO2 Probe A	Adjusted depth? on fixed boom. Depth is -10cm based on water level on 2017-05-10. All three eosCO2 sensors (sn GP20160070, sn GP20160069, sn GP20150111) are at -10cm depth because of low water level.
2638	2017-02-23	Lab none	Installed	Mayberry CO2 Probe A	Installed on the new water sensor boom in the top location - currently 8cm below the water surface
