OOI’s infrastructure consists of fixed and mobile platforms outfitted with scientific instruments and nodes that provide power and connectivity. The robust instrumented OOI arrays provide continuous streams of ocean data 24/7, in spite of operating in a challenging open ocean environment.
We report here on incidents that are currently affecting OOI’s infrastructure, including timelines for resolution. Most incidents are only temporary in nature, awaiting resolution for the next scheduled operations and management cruise.
|DATE||AFFECTED INFRASTRUCTURE||ISSUE||STATUS||ANTICIPATED RESOLUTION|
|5/2/22||Endurance Washington Shelf Surface Piercing Profiler||Recovered, but not redeployed||Software issues||Will be deployed in late July 2022|
|4/12/22||Endurance Inshore Surface Mooring||Lost cell phone communications||Switched to telemeter data back to shore via backup Iridium modem||Some data will be stored internally until recovery in September 2022|
|12/6/21||Endurance Array Gliders||Less than baseline number deployed||Baseline of six gliders in water is not always met due to maintenance cycles and weather curtailment of small ship operations||Gliders are prioritized on the Grays Harbor and Newport lines|
|11/9/21||Irminger Global Surface Mooring||Wind turbines damaged during major storm event||Decreased ability to generate power||Power, sampling, and data delivery will be actively managed|
|10/26/21||Irminger Flanking Mooring B||Potential failure of the secondary controller||Fluorometer and dissolved oxygen sensors no longer collecting data. pH and CTD sensors will continue to collect data, but not telemeter.||All available data will be downloaded during next cruise in June 2022|
|10/11/21||RCA Deep Profiler vehicle||Communication has been lost||Power was restored to subsystem, but initial attempts to restore communication did not succeed||Troubleshooting ongoing to restore communications|
|8/23/21||Global Station Papa Gliders||Gliders not on site||Data will not be telemetered until gliders deployed||Data will be downloaded during next cruise|
