Telemetered and recovered host data are unavailabe because of ground faults on the sealoor Multi-Function Node. All communications to the instruments were shut down.

All seafloor Multi-Function Node (MFD35 and MFD37) instruments have ceased data telemetry because the seafloor multi-function node had a high voltage ground fault and has been shut down to protect the instruments. Instrument on battery power will continue to collect data.

Data telemetry disabled due to chronic issues with power generation and management. The instruments could be revived to send data via telemetry when sufficient power is available. Note: Instruments may continue to collect data on internal battery power.

Deployment 11: *UPDATED 2020-06-22: As of 2020-05-05 the ISSM MFN is back online in a reduced power usage mode. All MFN instruments will be powered on and sample 4 times a day (as opposed to 6 times a day). Data from this instruments will be telemetered home with the exception of the OPTAA which will only be availabe upon recovery. *UPDATED 2020-04-27: The MFN has been offline since 2019-01-03 and no telemetered data are expected from MFN instruments for the remainder of the deployment.*MFN offline due to power shortage after WT2 failure from 12/27/2019 to 12/30/2019 and again from 1/3/2019 to 1/6/2019. Instruments with external batteries will continue to log data internally.

Deployment 11: UPDATED 2020-04-27: As of 2020-03-12 telemetered data for most instruments are being sent home via Iridium. A gap in telemetered data is expected between 2020-01-08 and 2020-03-12 and will not be backfilled but these data will be available upon recovery.* As of 2020-01-08 both fleet broadband telemetry pathways have failed and data can no longer be telemetered to shore from this mooring. Instruments will continue to log data which will be available upon recovery.

14 days of the missing data ['2017-07-24T00:59:59', '2017-08-06T22:59:59'] are found in the telemetered and recovered host. Are recovered-inst data incomplete?
