🌊 New research out now in ICES Journal of Marine Science!
Using #OneBenthic, we reveal large-scale spatial patterns in marine epifaunal communities. One of four #Cefas papers under OWEC POSEIDON.

Fantastic visit to Cefas this week, chatting with herring experts and channeling our inner ‘Raiders of the Lost Archives’ 📖🐟

📢New paper!

🐟📚Using fish stomach contents spanning over a century, we reveal long-term diet shifts (from larger bivalves to smaller opportunistic prey) in demersal fish species in the western North Sea.

See our latest @newcastleuni.bsky.social and Cefas paper by @georginahunt.bsky.social investigating long-term changes in the feeding of fish species in the North Sea. Plaice, dab and haddock exhibited marked dietary shifts throughout the early 20th century onlinelibrary.wiley.com/doi/10.1111/...
Century‐Scale Changes in the Feeding Patterns of Demersal Fish Species in the Western North Sea
Understanding the extent and magnitude of change in marine food webs requires historical data that predates modern monitoring efforts. Such information can provide invaluable insights into the longer...

In 2025, an explosion of common octopus appeared across the southwest coast of England

Dr. Keith Hiscock, MBA, explains what led to this “octopus bloom”, how it connects to long-term changes in our seas, and what it could mean for the future of UK marine life.

Did someone say it's take an octopus to work day?

Brilliant photos from @akwildlifefalmouth showing the extent of the octopus surge in the southwest. This Risso's dolphin seemed to be having fun 🐙
I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA

Great talk on using historical sources to map herring spawning grounds by @georginahunt.bsky.social for @projectfishistory.bsky.social.

🌍🚢🚲 The journey is part of the story!
We’re curious: how did you get to #ICESASC25?

We’re looking for the most sustainable (& maybe surprising!) journey to Klaipeda. Share your travel story & let’s celebrate the many ways our community is reducing its footprint while coming together for science.🌱💙

Join us today & Wedn in #ICESASC25 session R, where you can experience the breadth of @icesmarine.bsky.social science: from marine biodiversity & benthic ecology to fish biology & stock assessment to human dimensions - we have it all covered!
@johnkpinnegar.bsky.social @laurauusitalo.bsky.social

Looking forward to seeing you (as one of the co-conveners). I hope you’ve brought an umbrella!

🌀📣 “the scientific case for climate liability is closed “ says lead author of NEW Nature study: may be a game changer tracing and attributing climate damages such as from heat waves 🥵 back to emissions from individual fossil fuel companies #ClimateAction #CarbonMajors

www.nature.com/articles/s41...
Systematic attribution of heatwaves to the emissions of carbon majors - Nature
Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.
