Abstract
The United States is dismantling the Ocean Observatories Initiative (OOI), a national network of cabled and moored deep-ocean instruments that has delivered continuous, openly accessible measurements of the ocean interior for roughly a decade. This opinion argues that the decision is shortsighted and, on its own stated terms, difficult to defend. Removing functioning infrastructure engineered for about a quarter-century of service— after Congress twice restored its funding—would convert a modest annual operating expense into the permanent loss of an irreplaceable, multi-year data record that cannot be reconstructed once the time series is broken. The instruments measure properties of the deep ocean that satellites cannot directly observe, and they provide in-water reference data on which satellite products and forecast models depend. The arrays underpin fisheries, marine energy, and coastal-flood applications; contribute to monitoring of the Atlantic Meridional Overturning Circulation; and are part of an international scientific collaboration. The decommissioning further raises questions about Congress’s appropriations authority and cedes leadership in ocean observation at a moment when other Nations are expanding theirs. I conclude that the action should be paused, that the assets should remain in the water while legal review proceeds, and that a bridge in funding can preserve the option to continue observations until the underlying policy is reconsidered. The cost of watching the ocean is small; the cost of going blind is not.
