Prior to the use of UV lamps for biofouling mitigation, this sensor would routinely biofoul after the first 6-8 weeks of a deployment (more common during a spring/summer deployment). Users should carefully examine the data to determine if biofouling has begun to dominate the signal.

The high voltage lines providing power to the MFN via the CVT for CE09OSSM-00004 shorted out on 2017-01-22 at 08:31 UTC. Sea state was high, but not unusual for this time of year. Disabled future power scheduling to the MFN and applied an override to disable the CVT. No further data will be logged from the instruments on the MFN. This affects:
On DCL35:
* ADCPS (had already failed upon deployment)
* PCO2W -- should continue to autosample
* PHSEN -- should continue to autosample
* PRESF -- should continue to autosample
* VEL3D -- should continue to autosample
On DCL37
* CTDBP (plus DOSTA) -- should continue to autosample
* OPTAA
* ZPLSC -- had stopped reporting data early on in deployment, may still be autosampling

The use of UV lamps has been implemented for biofouling mitigation on this instrument as of 2018-03-26T01:39:00Z.

Method: telemetered

The high voltage power supply providing power to the seafloor dataloggers and instrumentation failed for reasons unknown at this time. No further telemetered data will be available for this deployment.

Method: telemetered
11/3/19, 3:45 AM

Power to the seafloor sensors failed. With the exception of the VEL3D and OPTAA, the sensors on the seafloor platform should continue to autonomously sample for the remainder of deployment. Until we recover and redeploy the mooring in the spring of 2020, no further telemetered data will be available from the seafloor sensors.

Due to a bug in the mooring telemetry system, data during this time range was not telemetered to shore. It was recorded on the mooring and instruments and will be available in the recovered data streams.

CE09OSSM-MFD37-03-DOSTAD000
Deployment: 2

There are no data from any delivery method available for deployment 2. This should be annotated in the system (according to the ingest csv, the instrument failed at deployment).

CE09OSSM-MFD37-03-DOSTAD000
Deployment: 7

Deployment 7 recovered_inst data should be available for download (the raw data file is available according to the ingest csv) or annotated to indicate why recovered_inst data are not available.
