The Woods Hole Oceanographic Institution has delayed a controversial climate change experiment that aimed to release sodium hydroxide into the ocean off the coast of Cape Cod. The project, called “Locking away Ocean Carbon in the Northeast Shelf and Slope” or LOC-NESS, was postponed from mid-September to next summer. The decision came after federal authorities raised concerns about potential impacts on the ecosystem.
The National Marine Fisheries Service warned that the project could “adversely affect federally-managed species and other NOAA trust resources.”
The experiment planned to dump 6,600 gallons of sodium hydroxide solution about 10 miles south of Normans Land, an island off Martha’s Vineyard. This would happen over two to three hours to create a patch of alkalinity in the water. Scientists would then monitor it for up to five days.
A second, larger phase scheduled for 2026 aimed to dump up to 66,000 gallons into the Wilkinson Basin, nearly 40 miles northeast of Provincetown. The Environmental Protection Agency had tentatively agreed to issue research permits for both phases. Woods Hole scientists acknowledged that their activities could cause “localized changes in the carbonate chemistry of the surface ocean waters” for a short period.
Concerns delay ocean alkalinity experiment
However, they stated that these impacts would not be severe or long-lasting. Despite these reassurances, the project has faced criticism from environmental groups and local fishermen.
Benjamin Day, a senior campaigner for Friends of the Earth, said it would be “unconscionable and irresponsible” to greenlight the dumping of a caustic substance into the oceans. Jerry Leeman, CEO of the New England Fishermen’s Stewardship Association, expressed concern about the potential economic impact on commercial and recreational fisheries in the region. Adam Subhas, an associate scientist at Woods Hole, emphasized the institution’s commitment to getting the science right.
He said the trial aims to expand understanding of the effectiveness and potential environmental impacts of ocean alkalinity enhancement. The delay of the experiment has sparked debate among locals and experts. Some argue that human-driven interventions in the ocean could have unintended negative consequences.
Others believe it is crucial to explore all possible methods to combat climate change. As the project remains pending EPA approval, discussions continue about the multifaceted nature of environmental science and the varied public reception to experimental approaches in combating climate change.
