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.

* UPDATED, 2019-01-25: After careful review, the original data product algorithm (pco2_pco2wat) for this sensor was found to contain an error that resulted in calculation of incorrect derived L1 pCO2 values. In consultation with the vendor, the algorithm has been corrected, verified, and uploaded to the OOI system. This update, effective 2019-01-10, applies to all deployments for this sensor. All derived L1
pCO2 data products generated prior to this date should be re-requested in order to ensure utilization of the correct algorithm. The updated algorithm can be viewed at https://github.com/oceanobservatories/ion-functions/blob/master/ion_functions/data/co2_functions.py. * Until further notice, derived L1 pCO2 data products from this sensor are incorrect and should not be used. A significant discrepancy has been uncovered between the pCO2 values from shipboard water samples vs. values calculated by OOI system. The pco2_pco2wat algorithm is under review and can be viewed at https://github.com/ooici/ion-functions/blob/master/ion_functions/data/co2_functions.py.

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 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.
