Researchers from the University of Leeds and other UK institutions are leading the SeaSTORE project, a collaborative effort with the fishing industry to directly measure how bottom trawling affects carbon stored in seabed sediments. The study, conducted in the Irish Sea during two cruises in 2026, aims to track carbon from the seabed through the water column to the atmosphere, addressing a key knowledge gap in climate science. Previous estimates suggested bottom trawling could release up to 370 million tonnes of CO2 annually, but this is based on limited evidence. SeaSTORE uses real trawlers and advanced sampling to provide concrete data on carbon fate under different conditions. The project's findings will inform UK policy on fisheries, biodiversity, and net zero goals. By understanding how trawling practices, gear types, and seabed composition influence carbon release, researchers hope to identify more sustainable fishing methods. The collaboration with fish producer organizations ensures that the research considers food security alongside environmental impact. The study also includes seasonal comparisons and will provide policymakers with robust evidence to design management measures that balance carbon protection with the needs of the fishing industry.

Good to see direct measurement instead of another model extrapolation. The 370 million tonnes figure from 2024 was always shaky. If this project can actually track carbon from seabed to atmosphere, it might settle the argument. Worth following.

The fact they're working with actual trawlers is the key detail. Most studies use experimental gear or lab setups. Real-world disturbance is messy but that's what we need to know. Also the seasonal comparison across winter and summer cruises is smart.

I'm skeptical about the 10-30% reactive carbon range. That's a wide spread. Hope they get better bounds. But the real question is how much of that reaches the atmosphere versus getting absorbed in the water column. The ocean is a big buffer.

This is a good example of science that actually informs policy. If they can show that certain trawling practices are less damaging, you can design regulations that don't just ban fishing outright. The trade-off between food and carbon is real.

The interesting part for me is the governance angle. If seabed carbon becomes part of national carbon accounting, that changes incentives. The fact they're feeding findings directly to Defra means we might see actual policy changes. But the evidence needs to be solid before anyone writes rules based on it.

Not my usual area but the logic is similar to building retrofits. You need to measure before you can manage. The direct measurement approach here is the right way to go. Also the collaboration with the fishing industry is smart, gets buy-in early.
