The Trump administration is dismantling a deep-sea ocean monitoring program, removing hundreds of observing sensors from the Pacific and Atlantic oceans.
The move threatens the ability of researchers to track critical climate indicators and ocean currents. Scientists said the loss of this data will hinder the understanding of global warming and its impact on marine ecosystems.
Federal officials announced the cuts this week as part of broader budget reductions. The administration said the program is not essential to government operations. The initiative carried a total cost of $368 million [1].
According to reports, more than 900 deep-sea ocean sensors will be pulled out [2]. These instruments are located in strategic regions, including waters near Washington, Oregon, Alaska, North Carolina, and Greenland [2].
The program focused on monitoring the Atlantic Meridional Overturning Circulation, or AMOC, and other deep-water systems. These sensors provide real-time data on temperature, salinity, and pressure, metrics that are vital for predicting weather patterns and sea-level rise.
Researchers expressed alarm over the decision. They said the removal of these instruments creates a gap in the historical record of ocean health. Because the sensors are located in remote areas, replacing them with private or international equipment may take years.
“The administration is cutting the program as part of budget reductions.”
The removal of these sensors represents a significant shift in U.S. climate policy, prioritizing immediate fiscal reductions over long-term environmental data collection. By eliminating monitoring in key areas like Greenland and the North Atlantic, the U.S. loses a primary source of data for the AMOC, a system of currents that regulates global climate. This may force the international scientific community to rely on fewer, potentially less accurate data points to predict catastrophic climate shifts.
