Deployment 1: Instrument flooded - no valid data available for this deployment.

Deployment 1: Status data sent from the buoy included leak detects in the buoy well, drop in battery voltage, and loss of wind turbine input. Upon recovery, the buoy was primarily intact but several instruments were damaged and/or missing. Ice build-up on the tower is speculated to be the cause for much of the damage. No telemetered or recovered_host data expected. Functional instruments could continue to collect data using internal battery power and storage cards.

Deployment 2: A period of violent weather caused power outages on multiple instruments. No telemetered or recovered_host data expected. Functional instruments could continue to collect data using internal battery power and storage cards. Upon recovery, the buoy well was flooded.

Deployment 3: Wind turbines were disabled due to evidence of ice build-up on the surface buoy tower. The platform's battery charge state declined steadily. As of 2017-01-15, all DCLs were shut down and the telemetry schedule was reduced to conserve power. Battery-powered instruments should continue to collect data. UPDATE 2017-04-07: With increasing daylight at this location, sufficient power was generated by solar panels to re-establish limited high-bandwidth telemetry and data transmission. UPDATE: at recovery, wind turbines were missing their hubs and blades, and one solar panel was missing.

Deployment 4: at 10:03 UTC on 12 October 2017 the Irminger Sea Surface Mooring stopped all communications. At recovery, the surface buoy was missing. The subsurface portion of the mooring had fallen to the seafloor and was recovered. CTDMOs, CTDBP-F, DOSTA, and ADCP instrumentation were full ocean depth rated and survived, although any recovered data available after 2017-10-12T10:03:00 are suspect. All other instrumentation imploded or flooded. The cause for the loss of the buoy is inconclusive.

Deployment 5: Battery voltage dropped below 24V. All DCLs were turned off. CPM1 was placed on a wake schedule. Data collection and telemetry will be irregular until voltage rebounds.

Deployment 6: *UPDATED 2020-04-27: As of 2020-02-21 data for most instruments are being telemetered again (via Iridium). A gap in telemetered data is expected between 2019-10-22 and 2020-02-21 and will not be backfilled but these data will be available upon recovery.*Both fleet broadband units have failed and no more telemetered data is expected at this time. Instruments are believed to be operating as normal and their data will be available upon recovery.

pressure_depth (dbar) is an array of fill values in all files. This variable should contain valid pressure data from the collocated CTD.

By Lori Garzio, on 3/22/19

GI01SUMO-RID16-02-FLORTD000

The automated valid data tests were triggered for all deployments because of the high percentage of fill values for seawater_scattering_coefficient and optical_backscatter.

9/10/14, 6:50 PM 8/22/15, 11:00 AM

Annotation ID 1521 indicates that the instrument flooded and there is no valid data from this deployment. Excluding from data range summary.

Data look suspect shortly after annotation ID 47 indicates violent weather caused multiple power outages. This time period should be investigated and annotated. Excluding from data range summary.

There are 2 days at the end of deployment 3 for which data are available in the telemetered stream and not the recovered_host stream. These data should be available in the recovered_host stream.

The surface buoy detached from the mooring and the subsurface portion of the mooring fell to the seafloor (see annotation ID 102). Excluding all mooring data for this time range from final statistics.
