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.

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