Surface flux data products (that use relative wind speed in the calculation) are currently not being produced when surface current data from the collocated VELPT are not available. A fix is in progress (Redmine 13111).

Deployment 1: Anemometer placement on the surface buoy yielded wind speeds that are too low, as determined by comparisons with ship measurements. Overcrowding of the upper halo with telemetry hardware and instrumentation could have partially blocked air flow, contributing to the low wind speeds, and could potentially affect air temperature and relatively humidity sensors as well.

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: Anemometer placement was corrected from Deployment 1, but wind speeds may still be low-biased (5-10%) at speeds > 5 m/s, as determined by comparisons with ship measurements and measurements from the FDCHP.

Deployment 2: In the beginning of the deployment, the conductivity and salinity measured by the two met sensors were offset by ~0.0025 S m-1 and ~0.025 psu, respectively. The offset decreased over time. Initial comparisons at deployment indicate this METBK's (GI01SUMO-SBD12-06-METBKA000) values more closely align with the values recorded by the ship.

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.

Deployment 6: Due to power concerns, the METBK2 heater was shut down on 11/12/2019. This shutdown impacts the precipitation data.

Annotation ID 346 needs to be updated when Redmine 13111 is complete - a similar annotation should be added to the Pioneer and Endurance METBKs until the issue is resolved

Surface current speeds are substantially higher for deployment 2 compared to other deployments. This should be investigated. A similar issue occurred on GA01SUMO METBKs.

There are telemetered data available at the end of the deployment, but no recovered_host data for the same time range. These data should be available in the recovered_host data stream.
