🚨New publication on carbon stocks in reed beds!

M Williamson et al. quantified C storage in reed stems, roots and sediment.

🌍 Most C was stored in the sediments and roots, and the highest total C storage was observed in the intermittent zone of the reed beds.

New publication!🌥️

Maija Peltola et al. have measured new particle formation and aerosol properties at the CoastClim coastal atmospheric observatory.

The fascinating results showed e.g. new particle formation at the coast occurred roughly as often as in a boreal forest.

🚨New publication!
Eva Rohlfer et al. show how the contribution of zoobenthos to seafloor respiration in coastal habitats varies with space and time.

🚨 New publication!

Federica Manca et al's network analyses show that marine macrophyte-animal associations can be highly structured and they are not random assemblages. Additionally, the key species bladderwrack is again showing how important it is!

🚨 New publication!

@ivanrodil.bsky.social et al studied effects of different types of detritus on seafloor fauna and bacteria using traditional and eDNA approaches.

Despite some differences between the methods, some common trends were detected.

👉Check out the results: doi.org/10.1007/s002...

🚨New publication
Thakur et al present the comprehensive atmospheric observatory @tvarminne.bsky.social.

Initial results: sea-air exchange of aerosol precursor gases, VOCs and CO2 at the coast are highly dynamic, influenced by meteorological and biological conditions.

New generation of aquatic scientists getting inspired by Anna Villnäs on board of r/v Augusta ☺️ @helsinki.fi @coastclim.bsky.social

Varmare klimat kan göra Östersjön till utsläppskälla Forskare: ”Kan bidra till ökad uppvärmning”

Vad händer med upptag och utsläpp av växthusgaser när havens ekosystem störs? Detta är en fråga vi i sommar studerat på Askölaboratoriet, vilket nu uppmärksammats i bl.a. i Rapport: @svtnyheter.bsky.social : www.svt.se/nyheter/loka...

A path towards appropriate degradation experiments for assessing carbon sequestration potential of macroalgae We systematically reviewed literature on macroalgal degradation. To date, most degradation experiments are carried out in aquaria or shallow environments, span short timescales or rarely incorporate ...

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.

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.

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!

Functional traits are moderate predictors of above‐ and below‐ground biomass in multispecies seagrass habitats Read the free Plain Language Summary for this article on the Journal blog.

🚨 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! 🌊🔥
