Leeds researchers study bottom trawling's carbon impact in Irish Sea

Leeds researchers are part of a new project measuring how bottom trawling affects carbon stored in the seabed and whether it releases CO2 into the atmosphere. The SeaSTORE project is using real fishing vessels in the Irish Sea to track carbon from the seabed through the water column to the air. This is the first study to combine sediment, water, and air measurements in one effort. The work could inform policy on fishing practices and carbon management. If trawling turns out to be a significant source of CO2, it may affect how fisheries are regulated and how blue carbon is accounted for. The researchers are measuring different gear types and trawling frequencies to understand what changes emissions. The project is a collaboration between several UK universities and research bodies. It aims to give decision makers a clearer picture of the trade-offs between food production and carbon storage.

Good to see actual field data on trawling and carbon. Previous work was mostly estimates. This project tracks from seabed to atmosphere, which is the missing piece. Hope the results feed into policy.

Interesting that they're measuring during real fishing activity. That gives a better picture than lab studies. The trade-off between food and carbon is real. Curious how the gear type affects emissions.

The key here is that they're measuring actual CO2 flux, not just carbon disturbance. That matters for any carbon accounting. If trawling turns sediments into a net source, that could affect blue carbon credits and fishing regulations.

First of its kind study is a big deal. Direct measurement of air-sea exchange is hard. This could finally give numbers for how much CO2 trawling releases. Worth watching.
