Trump Admin Dismantles $368M Ocean Monitoring

The Trump administration is dismantling a $368 million deep-ocean observation system deployed over the past decade to monitor coastal environments, marine ecosystems, and ocean currents affecting global climate. The National Science Foundation will remove over 900 deep-sea instruments anchored off Oregon, Washington, Alaska, North Carolina, and the Irminger Sea between Greenland and Iceland beginning in June, with removal taking approximately 15 months.

Scientists have relied on data from this network to understand how oceans absorb greenhouse gases, how ocean temperature changes affect fisheries and coastal flooding, and changes in the Atlantic Meridional Overturning Current, a critical global water circulation system that researchers warn may be weakening due to climate warming. A collapse of this current system could produce severe weather effects globally. Craig McLean, acting chief scientist at the National Oceanic and Atmospheric Administration during Trump's first term, stated the dismantling "reflects the further lack of understanding that the current administration has of scientific value and scientific merit" and said it pushes "the United States back yet again into a rear seat in global scientific leadership."

The Trump administration repeatedly attempted to defund the Ocean Observatories Initiative, proposing 80 percent budget cuts in both 2025 and 2026, though Congress restored the $48 million annual operating budget both times. The administration proceeded with decommissioning despite congressional opposition, forcing system managers to disable some instruments and reduce data collection in response to funding pressure.

Hilary Palevsky, professor of earth and environmental sciences at Boston College, has used Irminger Sea data for a decade to study ocean carbon dioxide absorption. She characterized the removal "without a plan to store them or to continue collecting data" as "very hasty," noting that "there's a lot of expertise that has the potential to be lost" given the engineering complexity of maintaining remote ocean instruments and the difficulty of rebuilding such systems.

The observation network, which began operating in 2016 and was designed to function for 25 years, provided critical data for understanding coastal weather, commercial fisheries, and climate-related environmental changes across multiple U.S. regions. Jim Edson, the marine meteorologist who led the initiative, called it "the world's most advanced continuously operating ocean observing systems."
