History for Forerunner-Eosense GP-001 GP20150111

Rec No.	Date	Loc From	Title	Loc To	Notes
5209	2021-03-16	Lab none	Installed	Mayberry CO2 Probe A	Installed at MB to replace sn GP20160070. It was installed at the same height as the miniDOT on the floating boom.
4967	2020-11-12	Sherman Wetland-Temp1 CO2 Probe	Removed	Lab none	Removed with decommissioning of Sherman Wetland Temp tower. Brought back to the lab for cleanup.
4412	2020-04-03	Sherman Wetland-Temp1 CO2 Probe	Adjusted	Sherman Wetland-Temp1 CO2 Probe	Lowered from air into shallow water by tower base.
4390	2020-01-30	East Pond CO2 Probe	Moved	Sherman Wetland-Temp1 CO2 Probe	Moved from East Pond to temporary tower at Sherman Wetland. No water near the tower to put the probe in, so it's hanging in the air for now.
4391	2019-10-02	Lab none	Installed	East Pond CO2 Probe	Installed at EP.
3393	2017-08-16	Mayberry CO2 Probe A	Removed	Lab none	Removed from MB because we changed our water profile from 3 sensors to 2 sensors.
4407	2017-05-25	Mayberry CO2 Probe A	Moved	Mayberry CO2 Probe A	Floating boom installed at MB. This sensor was located ~-17cm below the water level, co-located with sn GP201600070.
4406	2017-05-10	Mayberry CO2 Probe C	Moved	Mayberry CO2 Probe A	Moved from lower position to upper position 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.
2636	2017-02-23	Mayberry CO2 Probe B	Moved	Mayberry CO2 Probe C	Moved from the middle position on the fence post in the channel to the bottom position on the new water sensor boom.
2511	2016-10-26	Lab none	Installed	Mayberry CO2 Probe B	Installed probe at original 'mid' level with other water sensors. This level is at water surface right now due to low water table. This probe has its cable connector painted and covered with silicon sealant.
2209	2016-02-23	Factory	Calibration	Factory	Initial factory calibration.
