Mapping organic carbon vulnerable to mobile bottom fishing in currently unfished areas of the Norwegian continental margin
Abstract. Organic carbon stored in continental margin sediments might be at risk by widespread mobile bottom fishing, potentially leading to reductions of organic carbon stocks, increased ocean acidif...

A new review brings together over 30 UK & international scientists to assess the latest evidence on how human activities, including bottom trawling and climate pressures affect seabed organic carbon stores. Read the blog to see what the evidence shows👇🌊 marinescience.blog.gov.uk/2026/02/25/s...

Standing room only at our anthropogenic impacts on blue carbon #OSM26 session, followed by a vibrant poster session. Big challenges, but such a collegiate and engaging community working on it. Came away energised & more excited about our QUEST research, presented by Phoebe Walsh & Mark Chatting.

Brief offshore dalliance this week doing a few interesting tasks, such a tonic for the academic soul. To quote idiosyncratic, post-punk artists Sea Power: "The salt, the spray, the gorgeous undertow Always, always, always the sea" 🌊

🌊 New publication out! Key message: Measuring dry bulk density is as important as measuring organic carbon content when estimating organic carbon stocks. Shouldn't surprise, but needs to be said. Led by Mark Chatting (@ucddublin.bsky.social), with @drmarkyc.bsky.social, @biogeochembilly.bsky.social

A stimulating week at #EGU25. Co-convened a #bluecarbon session, w/Phoebe Walsh presenting her latest PhD research on trawling impacts & seafloor recovery. Shauna Creane & Aelita Totska presented a new sediment mobility tool, and Muireann Walsh gave her first PhD poster on Irish Sea morpodynamics 👏
