NSF pauses ocean sensor removals after Murkowski-led bill clears Senate

By THE ALASKA STORY

June 19, 2026 – The National Science Foundation has hit the pause button on its plan to suspend much of the Ocean Observatories Initiative, a network of ocean-monitoring sensors that provides data used by fishermen, weather forecasters, researchers, and coastal communities across the country.

Sen. Lisa Murkowski is claiming victory after the agency announced it would suspend plans to remove the sensors, a decision that came just one day after the US Senate unanimously passed bipartisan legislation she co-sponsored to block the effort.

“The National Science Foundation’s decision to leave the Ocean Observatories Initiative’s buoys in place is a massive win for coastal communities and fishermen around the country,” Murkowski said in a statement.”Today we saw the federal process at work—with the Senate quickly passing legislation and the executive branch responding to our position.”

The announcement came after Senate passage of the Saving the OOI Act, a short two-page bill sponsored by Murkowski and Sen. Jeff Merkley, D-Oregon. The legislation prohibits NSF from using federal funds to decommission or “descope” the Ocean Observatories Initiative until the agency completes a thorough review of the system and consults stakeholders.

In practical terms, the bill effectively halted NSF’s ability to continue dismantling the network.

NSF subsequently announced it would pause further removals, continue operating and maintaining existing infrastructure, redeploy some equipment, and convene an expert review panel while seeking broader public and scientific input.

The timing of the announcement appears to support Murkowski’s claim that congressional action directly influenced the agency’s decision.

“NSF’s decision came after Murkowski and Merkley passed a Senate bill to prohibit the NSF from dismantling the OOI system,” the senators’ joint statement noted.

The Ocean Observatories Initiative consists of a network of buoys, sensors, and underwater instruments that collect real-time ocean data. The information is used for fisheries management, weather forecasting, ocean safety, marine research, and climate studies.

Earlier this year, NSF had begun a process known as “descoping,” which would have removed most of the initiative’s arrays and sensors. Agency officials cited changing priorities, budget pressures, and recommendations from a National Academies review as reasons for scaling back the program.

The proposal drew swift bipartisan opposition from lawmakers, scientists, fishermen, and coastal communities who argued that dismantling the network would waste hundreds of millions of dollars in federal investments and eliminate valuable long-term datasets.

Critics also questioned whether NSF had followed proper congressional notification procedures before beginning the reductions.

Murkowski and Merkley responded by assembling a bipartisan coalition that included Alaska Sen. Dan Sullivan and senators from Washington, Oregon, Rhode Island, Wisconsin, Massachusetts, and Maryland. The group first pressed NSF through a letter demanding the agency reverse course and later advanced the Saving the OOI Act through the Senate.

While NSF is facing broader budget pressures and proposed spending reductions, the available record suggests the agency’s reversal was driven primarily by congressional oversight and legislative action rather than fears of future budget retaliation.

Murkowski’s own statement characterized the outcome as “the federal process at work,” with Congress exercising oversight authority and the executive branch adjusting its actions to comply with legislative direction.

The Senate’s action does not permanently preserve the Ocean Observatories Initiative. Instead, it prevents further dismantling until NSF conducts a comprehensive review and engages stakeholders about the future of the program.

Whether the system ultimately remains intact will depend on the outcome of the review process now being undertaken by NSF.
