Ocean science takes a hit as key climate tools disappear

Scientists are losing a powerful tool for tracking ocean changes this month. A deep-sea buoy, part of a high-tech network worth $386 million, will be pulled from the Pacific Ocean on June 16. The network, called the Ocean Observatories Initiative, has been gathering real-time data for over ten years. But now, most of its sensors are being removed by 2027. The National Science Foundation, which funded the project, calls it a "descoping" effort. They say they’re adapting to new scientific priorities and technology. Yet, researchers warn this move will leave big gaps in understanding ocean conditions. The shutdown comes at a critical time. An El Nino event, which warms ocean waters and disrupts weather, is expected soon. Already, warm water is spreading off California’s coast. Without the buoys and underwater gliders in Oregon and Washington, scientists will struggle to measure what’s happening below the surface. Satellites can track surface temperature and chlorophyll, but they miss deeper changes, like oxygen levels in the water. These details matter for marine life and climate studies.Built over a decade, the network was designed to run for 25 to 30 years. Ten years in, it was just hitting its stride. "We’ve got hints of patterns now, " said Ed Dever, a scientist involved in the project, "but we need decades of data to see real trends. " The shutdown follows a proposed 55% cut to the foundation’s budget last year, signaling a shift away from long-term research. One part of the network will survive: a seafloor cable off the Pacific Northwest. Managed by the University of Washington, it will keep tracking earthquakes and volcanic activity. But the loss of the broader system reflects a bigger trend. Federal support for basic science seems to be fading after decades of investment. This could slow progress in climate research, marine health, and disaster prediction.
