The U.S. National Science Foundation appreciates the concerns raised by the range of stakeholders that have informed us they rely on data from the Ocean Observatories Initiative (OOI). Effective immediately, NSF will not proceed with further removal or descoping of equipment from the remaining arrays and will continue operations including planned maintenance. While the Endurance Array has been removed from the water, we are developing plans to redeploy the equipment after servicing.

Moving forward, NSF will issue a Dear Colleague Letter to collect input from stakeholders and convene an expert panel to assess observational needs, evaluate available data sources, consider responses to the Dear Colleague Letter and help the agency identify a sustainable path for NSF's ocean observing systems. NSF remains committed to ocean sciences, to responsible stewardship of its research infrastructure and to supporting the stakeholders that depend on it.
