Sonic temperature bugs: general slow response problem leading to errors of +/- 6 degrees from ambient, and an additional nonlinear error in the slow response when the ambient temperature is between -5 and 5 degrees. The fast response (> 1 Hz) of these sensors is still accurate. Therefore, flux measurements using the detrended temperature data should still be valid. w bug: positive vertical velocities w output by the anemometer need to be multiplied by 1.166; negative vertical velocities need to be multiplied by 1.289 (Redmine 11645)

Flag: suspect Exclude: No

UPDATED, 2019-11-07: Per communication with the instrument subject matter expert, the onboard processing error applies only to the motion-corrected wind speed and flux calculations. Those parameters are marked here with a QC Flag = "fail". All other measurements are considered to be good. Users should only use the motion-corrected wind speed and flux data from the recovered instrument data stream. * The telemetered FDCHP data contains an onboard processing error that makes the motion-corrected wind speed and flux data unusable. The instrument subject matter expert is being consulted, and the algorithms are under review. Only the processed, recovered data should be used. For further questions please email help@oceanobservatories.org.

Deployment 1: Recovered_instrument data not available - instrument was lost.

Id: 624 By: lgarzio

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: No recovered_instrument data available for this deployment.

Id: 1399 By: lgarzio

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.

There are errors in the calculations of the recovered_instrument L1 and L2 data products (motion-corrected wind speeds, sonic temperature, and flux data products). This issue is under investigation (Redmine 13402).

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: Instrument damaged during deployment no telemetered or recovered data are expected.

Id: 1449 By: cdobson

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.

Id: 1625 By: cdobson

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.
