Trump administration abandons plan to dismantle ocean monitoring network

The Ocean Observatories Initiative sits on the front line of weather, fisheries, shipping and climate research, collecting data from more than 900 ocean sensors and deep-sea instruments tied to coastal and deep-water environments. Built for $386 million and operating since 2016, the network has fed more than 500 scientific publications while helping scientists track ocean circulation, marine ecosystems, climate change and extreme weather.

That system nearly lost much of its backbone. The National Science Foundation had planned to remove most of the instruments from waters off Oregon, Washington, Alaska, North Carolina and Greenland by 2027, with phased recovery and removal from the Endurance, Pioneer, Irminger Sea and Station Papa arrays over roughly 15 months. The first buoy off the Oregon coast had been scheduled for removal on June 16.

The reversal came after the Senate passed a bipartisan bill on Wednesday to block the removal of the deep-sea monitoring instruments. Senators Jeff Merkley of Oregon and Lisa Murkowski of Alaska led the push, joined by Sheldon Whitehouse, Tammy Baldwin, Patty Murray, Ron Wyden, Edward Markey, Elizabeth Warren, Chris Van Hollen, Maria Cantwell and Jack Reed. The lawmakers urged NSF Acting Director Brian Stone to stop the dismantling and carry out a full review with marine scientists and other stakeholders.

For coastal states, the stakes extended well beyond academic research. Merkley and his allies said the network provided critical information for emergency preparedness, fishery management and tracking major climate events such as El Niño. Scientists warned that losing continuous observations would weaken the ability to monitor coastal conditions, marine currents and dangerous weather, with knock-on effects for coastal safety and communities that depend on the sea for work and transport.

The fight also sharpened concern over the Atlantic Meridional Overturning Circulation, or AMOC, the vast current system that helps carry warmth to northern Europe and is increasingly viewed as vulnerable as the climate warms. Researchers have used the OOI data to study that system, and critics said cutting the network would damage a rare, long-running stream of ocean observations at exactly the moment climate risks are intensifying.

The National Science Foundation had described the plan as a “descoping” tied to changing scientific priorities and emerging technologies. House lawmakers escalated the pressure further on June 15, accusing the agency of acting illegally. For now, the bipartisan backlash has preserved a monitoring system that many Americans never knew existed, but that underpins decisions from storm readiness to fisheries to climate science.
