This is an excerpt from an article published in National Fisherman. With the launch of a set of guidance memos last week, the fishing industry established its leadership in a set of novel ocean-based climate interventions that could someday become one of the largest human activities in the ocean: marine carbon dioxide removal (mCDR).

At the end of February, the two of us made a trip to Glasgow, Scotland to attend the Ocean Sciences Meeting. This event, which happens every two years, bills itself as “the flagship conference for the ocean sciences and the larger ocean-connected community.” The conference’s offerings included every oceanography-related topic imaginable, but we were there with a focus: to learn everything we could about marine carbon dioxide removal.

In March and April 2025, 34 commercial fishermen and fisheries representatives met online for a series of roundtable discussions hosted through the Fishery Friendly Climate Action Campaign to discuss an emerging set of climate solutions collectively called marine carbon dioxide removal (mCDR). Today we announce the publication of a synthesis of those conversations.

This is an excerpt from an article published in National Fisherman. 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.

Sarah Schumann caught up with two of the lead scientists of WHOI’s LOC-NESS ocean alkalinity enhancement field trial in the Gulf of Maine: Adam Subhas and Jennie Rheuban. She was curious to hear how the experiment went from their standpoint, what kind of data they had collected, and what preliminary results they were ready to share from the field trial.

Sarah Schumann was a fishing industry observer on the August 2025 LOC-NESS ocean alkalinity enhancement field trial in the Gulf of Maine, in which WHOI engineers released 16,500 gallons of sodium hydroxide solution dyed with rhodamine tracer into surface waters to assess potential for carbon removal.

In this episode of the Maine Coast Doc Talk podcast, produced by the Maine Coast Fishermen’s Association, host and executive director Ben Martens chats with Dr. Adam Subhas of the Woods Hole Oceanographic Institution to explore the research initiative known as the LOC-NESS project. LOC-NESS stands for Locking Ocean Carbon in the Northeast Shelf and Slope and is testing the safety and effectiveness of ocean alkalinity enhancement to combat climate change.

At our May 28 webinar on “Marine Carbon Dioxide Removal: What Fishermen Need to Know,” a panel of four commercial fishermen and fisheries representatives reflected on their participation earlier this spring in a set of roundtables hosted through the Fishery Friendly Climate Action Campaign to support this project.

This is an excerpt from an article published in National Fisherman. This article is the second in a series for commercial fishermen about marine carbon dioxide removal (mCDR). mCDR is a set of experimental techniques that could someday play a major role in combating climate change by accelerating the ocean’s uptake and storage of heat-trapping carbon dioxide pollution from the atmosphere.

This is an excerpt from an article published in National Fisherman. Marine carbon dioxide removal (mCDR) is a set of experimental techniques that aim to accelerate the ocean’s uptake and storage of heat-trapping carbon dioxide pollution from the atmosphere. Someday, these techniques could play a major role in combating climate change. mCDR is not yet a major subject of fishermen’s daily dock talk, fishing association newsletters, or industry trade shows, but it’s time we make it one.

The final day of the Ocean Visions finished with a plenary session where panelists and audience members took turns at the mic to reflect on the three-day experience and share their visions for what comes next. A number of these comments focused on the fourth pillar of the Ocean Visions network’s agenda to confront the ocean-climate crisis: Reach. Ocean Visions recently added its “Reach” pillar to the other three pillars in its strategy (Remove, Repair, and Reduce) to ensure that “a wide array of diverse perspectives and backgrounds are fully engaged in pursuit of solutions.”

As the field of marine carbon dioxide removal (mCDR) jumps from the laboratory into the field, can it advance in a way that avoids crushing coastal communities? That was the unspoken question at the heart of a panel discussion on “Working with Communities at the Ocean-Science Nexus” at the Ocean Visions Summit in Vancouver, BC earlier this week.
