The main purpose of this legislation, known as the "Saving the OOI Act of 2026," is to protect the Ocean Observatories Initiative (OOI) by preventing the National Science Foundation (NSF) from using federal funds to reduce its scope or shut down its instruments. The OOI is a network of scientific instruments located in various coastal regions and seas that collect valuable data for research. Key provisions of the act include a requirement that the NSF cannot decommission or scale back the OOI instruments until it completes a thorough review of the initiative.
