CE02SHSM-RID26-06-PHSEND000	7/31/16, 8:00 PM	8/7/16, 8:00 PM	Plots of the pH data for CE02SHSM indicate that unit may be experiencing biofouling, causing increased variability in the data signal. Whatever was causing the spiky signal appears to have cleared and resolved itself. Id: 866 By: michaesm
CE02SHSM-RID26-06-PHSEND000	10/5/16, 8:00 PM	4/21/17, 8:00 PM	The PHSEN suddenly stopped reporting any data on 2016/10/06 07:30 UTC. Reason unknown. Id: 867 By: michaesm Flag: not_operational Exclude: No
CE02SHSM-RID26	5/8/17, 8:00 PM	5/13/17, 8:00 PM	Communications with instruments on the NSIF for CE02SHSM are offline. Monitoring current draws to the NSIF shows a pattern of increased and expected current draws every 15 minutes, corresponding to the instrument sampling schedules. This suggests that the DCLs and attached instruments are still operating, but communications to the system are offline, reason unknown. Affected systems are: CPM2, DCL26: ADCPT, VELPT, PHSEN, uCSPP (acoustic modem communications), NUTNR, SPKIR, DCL27: OPTAA, FLORT, DOSTA, CTDBP. NSIF communicated starting again early on the 14th. Logs from NSIF systems indicate that the systems and instruments are still working, pointing to a communications issue between the NSIF and the surface buoy telemetry system. Id: 865 By: michaesm Flag: not_available Exclude: No
CE02SHSM-RID26-06-PHSEND000	7/22/19, 2:35 AM	10/22/19, 11:32 AM	Data indicates the sensor has either fouled or the intake tubing has become clogged. Id: 1698 By: wingardc Flag: suspect Exclude: No
CE02SHSM-RID26 Method: telemetered	11/22/19, 3:45 PM	1/7/20, 1:30 PM	Due to reduced power on the mooring (limited recharging of the batteries with light winds and sea lions blocking the solar panels), we have had to reduce the operating schedule of the 7 meter platform. Normally we run the system continuously, but have reduced that schedule to hourly. Id: 1835 By: wingardc
CE02SHSM-RID26 Method: telemetered	1/7/20, 7:00 PM	1/13/20, 1:45 PM	Due to an intermittent communications issue with DCL26, we are not receiving data from the instruments consistently. We expect the data to be available upon mooring recovery. Id: 1890 By: wingardc Flag: not_available Exclude: No
CE02SHSM-RID26 Method: telemetered	1/13/20, 1:45 PM		During a large storm event on 2020-01-11, power from the wind turbines was lost. This is the primary means of recharging the battery system on the mooring. With the loss of recharging power, we have had to implement a conservative power model. These systems and instruments have been disabled for the foreseeable future, and no further data will collected from them. Id: 1902 By: wingardc Flag: not_operational Exclude: No
