Ocean Observatories Initiative Dismantling
Coverage from The Conversation, USA TODAY, and others
The Ocean Observatories Initiative is a network of deep-ocean instruments that has measured conditions such as temperature, salinity, currents, oxygen, and carbon dioxide across arrays in the Pacific and Atlantic.
Plans to remove much of its in-water infrastructure have raised concerns about gaps in continuous observations used to study ocean heat, marine ecosystems, climate risks, and the Atlantic Meridional Overturning Circulation. The debate also concerns the National Science Foundation’s approach to research infrastructure and the effects of reduced monitoring on scientists and communities that rely on ocean information.
