Ekologisk hållbarhet är en förutsättning för både ekonomiska och sociala värden – och måste sättas främst också i det kortsiktiga beslutsfattandet. Läs uppmaningen från @alfnorkko.bsky.social & Christoph Humborg @coastclim.bsky.social i @hbl.fi, med anledning av den pågående havskonferensen.

Spent the month of May on the beautiful Irish west coast quantifying BVOC-emissions from marine algae and seagrass. Fruitful collaboration between @helsinki.fi, @uniofgalway.bsky.social, @coastclim.bsky.social. @cmgustafsson.bsky.social @mikaelehn.bsky.social @ovadnevaite.bsky.social

Det är dags för Finland och Sverige att ta FNs havskonferens på allvar! @tvarminne.bsky.social @ostersjocentrum.bsky.social @coastclim.bsky.social @balticseacentre.bsky.social @helsinki.fi www.hbl.fi/2025-06-07/f...

New project: Heatwave-driven rewiring of coastal food webs, led by @skortsch.bsky.social, had a productive kick-off meeting at @tvarminne.bsky.social. They examine how marine heatwaves reshape food webs by integrating experiments, molecular tools, and food web modeling. #Warming #FoodWebs #DNAtools

Congratulations to Janina Pykäri for her award for the best presentation by an early-career researcher at the Baltic Sea Science Congress in Sopot! 🎉 Well done on disseminating the important work on the role of the seafloor animals in the carbon systems!

🚨 New Publication!! 🚨 The study by @cmgustafsson.bsky.social and collaborators from UWA found that the main biodiversity mechanism driving seagrass biomass stock is through dominance and co-existing species that show similarity in their functional traits.

🚨New paper out!🚨We show that #MarineHeatwaves amplify benthic metabolism and solute fluxes utilizing new developed #Hotfloor system-an in situ heating experiment. No major community shifts, but big functional changes! 🌊🔥 see here: doi.org/10.1111/1365... and the method here: doi.org/10.1002/lom3...

NEW PhD thesis! Roel Lammerant will defend the doctoral dissertation entitled "Functional perspective on the role of macrophytes in the coastal carbon cycle across different temporal and spatial scales" on Friday 4.4 at 13:00 at Tvärminne Zoological Station. Stream: helsinki.zoom.us/j/68659327422

Are the Oceans Reaching Their Limit? Join the Discussion at #ACCCImpactWeek on April 22. Top researchers from CoastClim participate @alfnorkko.bsky.social and Anna Villnäs. Register by April 9, the event is free of charge.

Coastal zones are identified as important natural carbon sinks globally, but in brackish environments like the Baltic Sea, knowledge of coastal carbon sequestration is limited. This new study shows that shallow and partly enclosed Baltic bays are significant sinks for carbon and nutrients.

Read a news article written by our New Zealand collaborator Prof. Simon Thrush. He writes about the importance of the findings from the joint CoastClim- @aucklanduni.bsky.social field campaign that was conducted earlier this year.

New publication! Gammal et al. sampled benthic macrofauna, solute fluxes and environmental variables at 3 shallow habitats throughout one year. Results show that the strength of biodiversity-function relationships really depends on which species are present in which habitat and during which season.

Finally in my hands! Graduated with distinction!🎓🌊🎉 Huge thanks to @dansmale1.bsky.social for an engaging defense discussion, my supervisors J. Norkko and @alfnorkko.bsky.social, and colleagues and supporters NottbeckFdn @coastclim.bsky.social RothFinland. Link to thesis: hdl.handle.net/10138/587464

Our researchers are exploring patterns in greenhouse gas emissions along the NZ coastline! Preliminary results agree with the findings from the Baltic Sea that stressed and degraded coastal ecosystems become net emitters of GHG:s, and highlights the importance of proper management of coastal areas.
