The National Science Foundation announced the recovery of all in-water instruments from the Ocean Observatories Initiative sites in the Pacific and Atlantic, including locations off Oregon, Washington, Alaska, North Carolina, and between Greenland and Iceland. The move follows the dismissal of the NSF's independent board and ends data collection begun in 2016 on the Atlantic Meridional Overturning Circulation.

Primary records from the NSF and Woods Hole Oceanographic Institution confirm the system was contracted for a minimum 25-year lifespan yet will cease operations after roughly 10 years, removing over 900 sensors tracking temperature, salinity, and current velocity. Comparable long-term arrays operated by the RAPID program at 26°N have documented a 15% weakening trend since 2004 in peer-reviewed outputs from Nature Geoscience.

Congressional statements reference the 2025 NSF budget justification, which reallocates funds away from sustained ocean observing; no replacement monitoring array is listed in the current NSF major facilities plan.
