New scientific report, co-funded by @eea.europa.eu, shows Europe's seas are in crisis: none of its regional seas are in good condition & only ~1% are strictly protected. The #EUOceanAct must turn fragmented commitments into binding, enforceable action. ➡️ europe.oceana.org/press-releas...

A fundamental shift occurred around 2009: the Arctic has flipped from being limited by light to being limited by nitrogen. As sea ice retreats, increased plant growth on shallow Arctic shelves is driving far greater loss of nitrate from the water, reshaping the base of the food web.

We have started our new @azti.bsky.social #GES4SEAS summer school, with 30 engaged people. Hope they can learn to use Tikta in assessing the status of ocean under multiple pressures #marineecology #research

Modernizing the EU fleet may boost fishing capacity, but unless carefully managed, this risks overfishing and further stressing already limited fish stocks. Can we innovate sustainably, or will progress tip the balance? www.frontiersin.org/journals/mar...

New paper on eutrophication in Denmark: The combination of a good idea, 2) two smart Master Students (Marie N. Jørgensen + Nanna Meilholm), 3) a good dataset, 4) the HEAT tool and 5) supervision by @ciaran-m.bsky.social has resulted in a must read published this week in Frontiers in Marine Science.

Are MPAs in the transition zone between the North Sea and the Baltic Sea effective? We have mapped cumulative effects of multiple stressors in the Skagerrak. Anchored in this, and a statistical model, we have compared pressures within outside the MPAs. Most MPAs are so-called 'paper parks'.

Today is #WorldWildlifeDay2026 and it is a good day to launch our #GES4SEAS Tikta software to assess the cumulative effects at sea and its environmental status. Learn here in this video #MarineEcology #Research youtu.be/POx9iXz1ufo

Combined effects of multiple pressures pose critical threats to marine ecosystems. We have mapped where multiple pressures coincide with sensitive habitats and species, identifying hot spots and cold spots (ie high and low human impact). www.frontiersin.org/journals/mar... @2xges.bsky.social et al.

3/3 In my view, the editor’s decision to publish a rebuttal that fails to address the core issues was a poor choice. - Original paper: pubmed.ncbi.nlm.nih.gov/40892922 - Our letter: pubmed.ncbi.nlm.nih.gov/41758658 - The reply: pubmed.ncbi.nlm.nih.gov/41758660 🌊

‼️ Check out our new paper led by Laura Castro de la Guardia. We estimate the potential kelp biomass from seafloor irradiance. Predicted potential kelp biomass in 6 Arctic fjords in good agreement with published values. 🌊 @iddri.bsky.social @cnrs.fr aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

Deeply honored receiving today the #Odum Lifetime Award from @cerfscience.bsky.social the same day, just 41 years after defending my PhD thesis

As chair of #ECSA61: Bridging the gap between science and policy in estuarine and coastal marine biodiversity: the way forward, I invite you to propose sessions until 29th November. The conference is from 24-27 August 2026 at Square, Brussels, Belgium app.oxfordabstracts.com/auth?redirec...

But hasn’t HELCOM producer and published 3 Integrated Ecosystem Assessments since 2010 (HOLAS1, HOLAS2 and HOLAS3)? All 3 seems to be data- and tool-based using HEAT, BEAT, CHASE and BSPI/BSII. All these tools are fully documented in peer-reviewed articles.

📣🌊 A joint statement for and from the Baltic The side event by ICES and DG MARE alongside #ICESASC25 last week concludes with a joint statement calling for adaptive science, coordinated governance across sectors, and new tools to support Baltic Sea recovery. ➡️Learn more: https://bit.ly/3KbQeuD

🌊 Scientists from University of Exeter and @pml.ac.uk have urged caution in upscaling ocean carbon removal technologies until the environmental impacts are better understood. @exetermarine.bsky.social @gsiexeter.bsky.social @guyhooper.bsky.social news.exeter.ac.uk/faculty-of-e...
