Scientists warn Trump plan to axe US ocean monitoring system will leave world ‘flying blind’

Lead

Scientists have warned that the Trump administration's plan to dismantle a major US ocean monitoring system will severely degrade global climate and weather forecasting, leaving the world "flying blind" on ocean heating and storm predictions. The Ocean Observatories Initiative (OOI), a $368 million deep-sea observation network primarily funded by the US National Science Foundation, is being decommissioned, with hundreds of instruments already being removed from waters off the US coasts and the North Atlantic.

According to research published last month in Nature Climate Change, losing US observations alone would produce a 163% increase in error for annual ocean heating rates. The study, cited by The Guardian, warned that dismantling the OOI would remove a vital component of the Global Ocean Observing System (GOOS), a UN-coordinated network of robotic floats, moored buoys, and research vessels that experts describe as the "eyes and ears" of the ocean.

Coverage Comparison

The Guardian's report framed the story around the climate crisis, emphasizing the economic consequences of dismantling the OOI. It quoted Sabrina Speich, an ocean monitoring expert at the École Normale Supérieure in Paris and chair of the ocean expert panel of the Global Climate Observing System, who said that forecasts and early warning systems for storms, tropical cyclones, and El Niño would degrade "sometimes dangerously so."

RFI, the French public broadcaster, focused on the environmental impact, reporting that more than 900 deep-sea instruments anchored near the US Atlantic and Pacific coasts and in the Irminger Sea between Greenland and Iceland are to be removed from this month. The report, which cited The New York Times, noted that the process has already started at a location off the northwest US coast and is expected to last 15 months, according to Jim Edson, the lead scientist for the OOI, in a note to researchers in May.

Both outlets noted the significance of World Oceans Day (June 8) as the backdrop for the coverage, and both highlighted the European Union's response: the EU is investing €92 million in a new initiative called OceanEye to boost its ocean monitoring capabilities.

Key Claims

• Dismantling the OOI would severely degrade weather and El Niño forecasts: Experts cited by The Guardian said that losing US ocean observations would lead to a massive increase in error in annual estimates of ocean heating rates, which underpin weather prediction, El Niño forecasting, and fisheries management.

• The loss of US data would be worse than randomly losing 80% of all ocean data worldwide: The Nature Climate Change study showed that because US observations are strategically placed and crucial for global coverage, their removal would have a disproportionate impact on global data accuracy.

• Ocean observations save lives: Scientists emphasized that the warning systems based on OOI data "save lives" by providing early warnings for severe storms, tropical cyclones, and El Niño events. Sabrina Speich told The Guardian that degradation could be "dangerously so" in some cases.

• The US government says the program is not being cancelled entirely: An NSF spokesperson said the plans are a "reduction of elements" and align with the agency's "nimbler approach to prioritise support for evolving scientific priorities and emerging technologies." It is not clear what data collection capacity would be left.

• The EU is investing in OceanEye: A €92 million initiative to enhance European ocean monitoring, as reported by The Guardian. This is seen as a partial counterweight to the US cuts, though experts note that no regional system can fully replace the global coverage provided by the OOI.

• The World Meteorological Organization warned of an 80% chance of El Niño developing between June and August: This forecast, cited by RFI, underscores the timing of the cuts, as reliable ocean data is critical for tracking such phenomena.

Perspectives

Scientific Community

Researchers and ocean monitoring experts express alarm, describing the dismantling as "penny-wise, pound foolish" given the economic and human costs of degraded forecasts. They stress that ocean observations are irreplaceable because we cannot see the deep ocean from space, and they save lives by warning of severe storms.

US Government / NSF

The National Science Foundation maintains that the program is not being cancelled entirely and that the changes are part of a strategic shift toward more flexible and emerging technologies. The NSF spokesperson emphasized a "nimbler approach" to prioritize evolving scientific priorities.

European Union / International Partners

The EU's investment in OceanEye reflects a recognition of the critical importance of ocean monitoring for climate and weather. However, experts caution that regional efforts cannot fully compensate for the loss of US data, which is a linchpin of the global observing system.

Conclusion

As the US proceeds with removing deep-sea instruments over the coming months, the international scientific community is bracing for a period of reduced forecasting accuracy. The full consequences may not be immediately visible, but researchers warn that the impacts on weather prediction, climate research, and disaster preparedness will be felt worldwide. The EU's OceanEye initiative offers some hope for strengthened European monitoring, but the loss of the OOI remains a significant blow to global ocean science.
