US Government Reverses Decision to Shut Down Ocean Monitoring Network

Quick Look

  • The US federal government is reversing its decision to dismantle the Ocean Observatories Initiative (OOI), a $350 million ocean monitoring network.
  • The shutdown, initially announced without reason, had drawn widespread opposition due to the OOI's crucial data for climate change tracking, weather forecasting, and fisheries management.

Why It Matters

The federal government's decision to shut down the $350 million Ocean Observatories Initiative (OOI) network in May drew widespread opposition due to its value for climate change tracking, weather forecasting, and fisheries management.

In May, the federal government announced without warning that it would take apart a network of ocean monitoring systems that it had spent over $350 million to build.

No reason was given for the decision to shut down the Ocean Observatories Initiative (OOI), but suspicion immediately focused on the network’s role in tracking climate change.

But the OOI also provides data that’s useful for weather forecasting and fisheries management, leading to widespread opposition. Today, it appears that the opposition has won, as the government will announce that it’s reversing the decision. The big remaining question is how much damage the OOI took during the intervening month.

As of now, there is no formal statement available from the federal government. However, The New York Times reports that the decision will be announced later today, and Ars received a statement from Zoe Lofgren, the ranking Democrat on the House Science Committee, indicating that the decision has been made.

The OOI is a federally supported resource that provides ocean data for use by academic researchers, government planners, and private companies. It consists of arrays of monitoring systems in several locations in both the Atlantic and Pacific Oceans that can track things like currents, salinity, chemical levels, temperatures, and tectonic activity. (There are over 100 individual entries on the page that display the data gathered by the system.)

Obviously, there are many potential uses of that data. The fact that it has been gathered continuously for a decade means it can help track changes in how carbon dioxide and heat enter the oceans. This is probably what made it a target for the climate change denialists who helped set the Trump administration’s policy.

Those policymakers are perfectly happy to annoy people with environmental concerns, but they apparently neglected to consider how upset everyone else would be about losing access to the other data. The ensuing public backlash led the Senate on Wednesday to unanimously agree with a measure that would block the government from taking down the OOI. Today’s decision may indicate that the administration recognized it had gotten itself into a fight it knew it was losing.

The big question is whether some of the monitoring equipment has already been removed. “We also don’t yet know how much damage they have already done,” Lofgren’s statement said. “To be clear, this should have never happened. This pathetic scheme was illegal.” For now, however, it appears that this is one instance where we won’t have to wait for the courts to decide whether that last claim is accurate.
