Ocean sensors will go dark under Trump funding cuts

Key Points:

• The Ocean Observatories Initiative, a $386 million network of over 900 ocean sensors that has provided real-time data for more than a decade, will begin dismantling key components off the Oregon coast starting June 16, with full removal planned by 2027.
• Funded by the National Science Foundation (NSF), the initiative has been crucial for tracking ocean circulation, ecosystems, climate change, and extreme weather, contributing to over 500 scientific publications, but NSF cites a strategic shift toward evolving scientific priorities and emerging technologies as reasons for the "descoping."
• Scientists warn that the timing is detrimental, as an El Nino event and marine heat waves are expected this summer, and losing underwater monitoring capabilities will severely limit understanding of subsurface ocean conditions, which satellites alone cannot capture.
• The project, originally designed for 25 to 30 years to capture long-term climate signals, will now be cut short after just over 10 years of data collection, marking a significant loss for oceanographic research and federal commitment to basic science.
• A seafloor cable network managed by the University of Washington will remain operational to monitor volcanic and seismic activity, but overall, the dismantling reflects broader budget cuts and a trend of reducing federal support for large-scale scientific infrastructure.
