Summary

Story summary

U.S. President Donald Trump’s administration, via the National Science Foundation, began removing Ocean Observatories Initiative instruments from four of five arrays.
The OOI system cost $370 million to build, costs $48 million annually, and holds more than 900 deep-sea instruments.
Scientists warn that losing the sensors will curb monitoring of the Atlantic meridional overturning circulation.
The NSF’s FY 2026 budget request seeks an 80 percent cut, while the Cabled Array off Oregon remains active.

History

Historical Context

Building on the Argos satellite system created in 1978 by NOAA, NASA and France’s CNES, the Argo profiling-float program uses autonomous APEX floats to sample temperature and salinity worldwide. The network strives to maintain roughly 3,000 operational floats, but funding uncertainties risk its continuity. The Argos system also underpins other global research programs such as TOGA and WOCE.
