August 29, 2025 — The U.S.’s first ocean alkalinity enhancement (OAE) field trial in federal waters took place on Aug. 13, with the dispersal of 16,500 gallons of sodium hydroxide into the Gulf of Maine. Led by a team of Woods Hole Oceanographic Institute (WHOI) scientists, this milestone represents the culmination of three years of planning, which for the last year has included a steady stream of feedback (including some unvarnished pushback) from the fishing industry.
I joined the field trial as a fishing industry observer, and this is my report to the fleet.
Fishing industry involvement in project planning
Ocean alkalinity enhancement was an enigmatic term to the New England fishermen who heard it for the first time in summer 2024, when the EPA opened a public comment period for input on a permit WHOI’s LOC-NESS (Locking Away Carbon in the Northeast Shelf and Slope) project.
“We don’t have a lot of tolerance for your curiosity right now,” and “The ocean’s not a lab rat,” were some of the comments made by anxious fishermen during the first informational meetings hosted by the WHOI team.
In the year since that first exposure, fishermen and their representatives have attended numerous meetings with the LOC-NESS team at port meetings, trade shows, and New England Fisheries Management Council meetings. As a result of fishermen’s input, the scientists changed the planned location of the project and lined up federal funding (later retracted) to test the effects of sodium hydroxide on the larval and egg stages of commercially important species like lobster and herring.
When the time came to perform the field trial, it seemed appropriate to ask if a fisherman could witness the event as an observer, so I asked if I could tag along. They were happy to oblige, and even set aside a tie-up stipend so I wouldn’t lose income due to time away from my fishing job.
