NSF Reversed Plan to Pull 900 Ocean Sensors. Senate Forced the Issue.

Resist Now 3 min read

The National Science Foundation announced on June 19, 2026 that it will not remove any more equipment from the Ocean Observatories Initiative, a network of more than 900 instruments positioned across U.S. ocean waters. The reversal came one day after the U.S. Senate passed the “Saving the OOI Act” by unanimous consent.

NSF’s Own System Was Targeted for Dismantlement

The Ocean Observatories Initiative was installed roughly a decade ago at a cost of $386 million and was built to operate for 30 years. The instruments monitor ocean currents, water temperatures, sea life, and related conditions. That data is used by meteorologists preparing for extreme weather, fisheries managers, and climate researchers.

The Trump administration had framed partial removal of the instruments as a “descoping,” not a shutdown. NSF had already removed the Endurance Array, a set of instruments stationed along the Oregon and Washington coastlines, before the reversal. The agency now says it is developing plans to redeploy that equipment after servicing.

“The U.S. National Science Foundation appreciates the concerns raised by the range of stakeholders that have informed us they rely on data from the Ocean Observatories Initiative.”

Unanimous Senate Vote Preceded the Reversal by One Day

Sen. Lisa Murkowski (R-AK) and Sen. Jeff Merkley (D-OR) introduced the Saving the OOI Act and brought it to the Senate floor on June 18, 2026. It passed by unanimous consent, meaning no senator objected. The bill prohibits federal spending to decommission any part of the OOI without a thorough review that includes the scientists, fisheries managers, and industries that use the data.

The vote reflected pressure from scientists, the commercial fishing industry, and members of Congress from coastal states. Alaska has more coastline than all other states combined, and its commercial fisheries industry generates billions of dollars annually. Murkowski has been one of the most prominent congressional defenders of the system.

The Saving the OOI Act still needs to pass the House and be signed into law to become permanent policy. The NSF reversal is an administrative decision and can be undone.

What You Can Do Now

  1. Call your House representative at (202) 225-3121 and ask them to bring the Saving the OOI Act to the House floor for a vote. Tell them the Senate passed it unanimously and the NSF reversal is not permanent without legislation.

  2. Contact the House Science, Space, and Technology Committee, which oversees NSF. The chair is Rep. Brian Babin (R-TX). His office can be reached at (202) 225-1555. Ask the committee to schedule a markup of the Saving the OOI Act.

  3. If you work in fishing, weather forecasting, or coastal emergency management, contact the NSF Office of Legislative and Public Affairs at (703) 292-8070 and describe how you use OOI data. NSF cited stakeholder pressure as the reason for reversing course.

  4. Track the Saving the OOI Act at Congress.gov by searching “Saving the OOI Act” to monitor if and when it advances in the House. Sign up for alerts so you know when a floor vote is scheduled.
