Merkley, Murkowski Continue Oversight of Restoring NSF Ocean Monitoring Systems

Merkley, Murkowski Continue Oversight of Restoring NSF Ocean Monitoring Systems July 30, 2026 Washington, D.C. –  Today, U.S. Senators Jeff Merkley (D-OR) and Lisa Murkowski (R-AK) pressed the National Science Foundation (NSF) to provide an update on the agency’s plans to redeploy vital Ocean Observatories Initiative (OOI) sensors. The bipartisan letter follows the Senators securing a commitment from NSF to pause its planned removal of the OOI sensors, a complex system of 900 ocean monitoring instruments that provides crucial data for coastal communities, fishermen, and nationwide emergency preparedness. While many other parts of the OOI remain in the ocean around the globe, Oregon’s removed Endurance Array devices still need to be redeployed by the NSF, which requires agency funding and personnel. Without the restoration of full OOI Endurance Array operations, Pacific Northwest researchers and fishermen will be left without access to critical data during the busy summer and fall months. “We respectfully request an update on NSF’s efforts to restore all OOI operational capabilities, including the Endurance Array, with information on the status of rescoping activities approved with budget as well as rescoping activities requested but still awaiting budget authority approval,” Merkley and Murkowski wrote. “Budget uncertainties impact the OOI program’s ability to retain the necessary personnel to operate and maintain the OOI, and we urge NSF to provide the budget certainty needed to hire and retain the personnel for redeployment, as well as ongoing operations and maintenance.” Merkley and Murkowski also highlighted that the NSF has yet to begin collecting input from stakeholders on the OOI, despite the agency’s June 18th statement that it would. They stressed, “For this review, we encourage due consideration of input from and inclusion on the review panel of a broad range of representatives including users and stakeholders of ocean observing facilities. We also urge a transparent process for conducting the review, recommendations, and implementation plans. Finally, we ask that NSF brief us on the recommendations and implementation plans prior to finalization. We look forward to collaborating with the agency, communities, and experts to unlock the next generation of improved ocean monitoring and high-tech data collection.” Previously, Merkley and Murkowski teamed up to block the NSF’s planned removal of the OOI’s sensors . The effort followed Senate passage of their Saving the OOI Act , a simple two-page bill that says no federal funds shall be used to decommission the OOI system until the NSF conducts a thorough review and assessment of the network with robust stakeholder engagement.

We are grateful for your responsiveness to our calls and those of stakeholders to preserve this vital, one-of-a-kind ocean monitoring network that so many Americans rely on. In the NSF update on the OOI, NSF committed to “not proceed with further removal or descoping of equipment from the remaining arrays and will continue operations including planned maintenance. While the Endurance Array has been removed from the water, we are developing plans to redeploy the equipment after servicing.” We understand and appreciate that NSF moved expeditiously following this statement to initiate OOI rescoping for the Endurance Array, including the approval of budget authority and ship time needed to resume some of the operational capabilities of the Endurance Array. We are grateful for NSF’s commitment to resume full OOI operations and understand that there are ongoing budget complexities and uncertainties within the agency. We respectfully request an update on NSF’s efforts to restore all OOI operational capabilities, including the Endurance Array, with information on the status of rescoping activities approved with budget as well as rescoping activities requested but still awaiting budget authority approval. Budget uncertainties impact the OOI program’s ability to retain the necessary personnel to operate and maintain the OOI, and we urge NSF to provide the budget certainty needed to hire and retain the personnel for redeployment, as well as ongoing operations and maintenance. Additionally, the NSF’s June 18th statement indicates the agency’s intention to issue a Dear Colleague Letter (DCL) to collect input from a diverse array of stakeholders, while convening an expert panel to assess ocean observational needs, evaluate available data sources, consider responses from stakeholders, and help the NSF identify a sustainable path for ocean observing systems. We eagerly await the issuance of the NSF’s DCL. For this review, we encourage due consideration of input from and inc
