New 🧪paper: We show the importance of selecting several indicators, both diversity and trait-based, to capture the broader signals of change in benthic communities due to bottom trawling activities.

Has Israel stopped starving & murdering Palestinians? Have all the Palestinian hostages been released? Are the settlements being dismantled? Is the occupation over? Do Palestinians have the right to return to their homes? Do we have accountability &justice for Israels war crimes?

It was nice to see the progress of the participants during the @icesmarine.bsky.social training course on assessment of the seabed impacts of bottom trawling. Some participants even completed a first draft assessment for their own region using new data!

📢Putting the spotlight on early-career scientists!
Do you know an ECS whose work should take centre stage?
Nominate them to be our early-career scientist keynote speaker at ICES ASC 2026.

It would be great if we could take a whole country and change the default speed limit to 20mph and then compare it to one left at 30mph. What if it reduced casualties by 25% and with lower risk reduced insurance premiums by £45 a year? Well it did! bit.ly/4gIBPlJ

Started my travels to teach an @icesmarine.bsky.social training course on the bottom trawling risk assessment method that we have been applying in WGFBIT. Currently cruising through Belgium on the Eurostar, continuing tomorrow to Copenhagen after a night at my parents.

In @projectfishistory.bsky.social we're after any historical records of herring fishing and spawning, so hearing about these kind of traps is very useful.

The “E-Bike Effect:” Those who bought e-bikes increased their average daily bicycle use from 2.1km (1.3 miles) to 9.2km (5.7 miles), a 340% increase. The e-bike share of all their transportation increased dramatically too; from 17% to 49%.

E-bikes support fewer car trips.

E-Bikers Ride Much Farther and More Frequently Than Regular Bikers
They are not 'cheating,' but are serious transportation.

Israeli quadcopters shooting children.

And our government continues to materially supporting Israel every day.

Even as Israel rejects a two state solution, votes to fully annex the West Bank, and murders more doctors, nurses, journalists, children.

And our government continues to assist it.

As Welcome Week, in great weather (the sun always shines in north Wales!), is drawing to a close we thank the SOS peer guides for their efforts. They are the friendly faces behind Welcome Week and put a lot of work in to make the freshers (aka The Peerlings) feel at home.

A great day for the annual SOS beach trip with the new undergraduate students @bangoruniversity.bsky.social. Sandcastles were built, beach pictionary played, and much fun had by students new and old, and staff.
A picture of sandy beach flanked by rocky outcrops on both sides. The sun is shining, the sky is blue with a few clouds, and the sea is calm.

Chloe Macleavy and Jasmine Scott-Dickins are both studying Marine Biology at SOS and are currently doing their placement year as research officers with Trashfree Trails (TFT). At the moment they are planning a litter research fieldwork day which will take place in Newborough Nature reserve.
Trashfree trails staff standing at the edge of a wooded area with a sign explaing what TFT is about: reconnect people with nature through the simple yet meaningful act of removing single use pollution from wild places. Happy TFT staff member Jasmine in their gazebo promoting the work of the foundation. A TFT staff member holding used energy gel packs above a sign saying "Don't be a gel end!"

SOS 3rd year marine biology students enjoyed their fieldwork at the Virginia Institute for Marine Science earlier this month. The weather was almost as good as in North Wales at the time...
People wearing life jackets are sitting in an open boat looking at samples taken from the sea. The sea is calm and teh sky is blue behind them.

Another critique showing that the Sala et al. 2021 estimate of carbon release by bottom trawling is ridiculous.

It estimates an increase in NW European shelf OC mineralization of 0.27 Mt C yr−1, which is an order of magnitude smaller the previous estimates.

Starting the last day of my travel back from the #ICESASC25 in Lithuania (train ferry combo). The travel was fairly cheap with interrail with the ferry was only £126 return. But it does take 3 days 🙂 @sosbangor.bsky.social @icesmarine.bsky.social

Ruth Clarke, a third year Marine Biology and Oceanography student at SOS, is currently doing a placement year with @seatrustwales.bsky.social in Pembrokeshire to gain wider skills in conservation related topics.
A woman in water proofs is looking out over the ocean using a camera with a very large telescope lens. 
Two people are standing behind a table with exhibition material from Sea Trust Wales. Ruth is standing at the top of cliff looking out over the ocean and helping release tagged sea birds. A crab is looking angrily into the camera.
