According to Roesler and Barnard (Optical proxy for phytoplankton biomass in the absence of photophysiology: Rethinking the absorption line height, Methods in Oceanography, 2013), “absorption meters are highly prone to biofouling, particularly biofilms which not only attenuate the collimated beam but also impact the scattering properties of the optical surfaces and tubes. In productive coastal waters biofouling can have significant impacts (i.e. 10% of the signal) within one to two weeks”. By Lori Garzio, on 6/27/19 |

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. By Lori Garzio, on 1/15/19 |

Per vendor feedback, the first 1-2 min of each AC-S instrument sampling period should be considered suspect. Signal drift can occur as the instrument warms up, flushes with seawater, and the filter wheel spins up. Id: 1799 By: swhite |

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. Id: 46 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. Id: 47 By: lgarzio |

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. Id: 121 By: lgarzio |

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. Id: 102 By: lgarzio |

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 |

Due to a glitch the OPTAA instrument was powered on continuously and sampling from 27 Sept 2019 00:00 UTC to 01:05 UTC. Due to the way that time is recorded on the instrument it is possible that the 01:00 to 01:04 data will be time-stamped as 02:00 to 02:04. Id: 1865 By: swhite |

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. Id: 1743 By: cdobson |
