June 3, 2026 — The administration of U.S. President Donald Trump is dismantling a deep-ocean observation system put in place over a decade ago, leaving gaps in scientific data that assists in everything from storm forecasting to fishery health.
The Ocean Observatories Initiative (OOI) consists of six different underwater monitoring arrays that the U.S. National Science Foundation (NSF) said is the most advanced continuously-operated observing systems in the world. Using hundreds of different instruments, the arrays provide openly-accessible data to oceanographers, researchers, educators, and the public.
