Infrastructure Status

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.

Note while the Global Argentine Basin (decommissioned January 2018) and Southern Ocean Arrays (decommissioned January 2020) are no longer in the water,  their data remain available, searchable, and downloadable on Data Explorer.

Any potential impacts on data, including time frame and resolution, are provided in data annotations on the Data Portal and Data Explorer.

10/23/23Endurance Washington offshore mooringLost communication with bottom instrumentsSeven internally recording instruments will continue to collect data.3-D single point velocity meter and spectrophotometer will no longer log. Internally collected data will be recovered and real-time bottom data restored on spring 2024 mooring expedition.
4/24/23Endurance Washington Shelf Coastal Piercing ProfilerNot deployedDue to ship availability and weather constraints deployment delayedIt will next be deployed on the spring 2024 mooring cruise
8/15/22Endurance Array GlidersLess than baseline of six gliders in water is not always met. Maintenance cycles and weather curtailment of small ship operations cause this.Gliders are prioritized on the Grays Harbor and Newport glider lines.
