Check out our new review paper, championed by Lydia White, "A path towards appropriate degradation experiments for assessing carbon sequestration potential of macroalgae". Read it here: besjournals.onlinelibrary.wiley.com/doi/10.1111/... @coastclim.bsky.social @tvarminne.bsky.social #mCDR
Jeij! So cool to see our work featured on the cover of the August issue of Functional Ecology - A Special Issue on Marine Heatwaves.
Emissions from marine plants and algae (BVOCs) play a significant role in the global carbon cycle and for the climate. How do the emissions on the Atlantic coast compare to emissions in the Baltic Sea?

🚨 NEW paper alert!
#Seagrass #functional #traits act as predictors of #biomass, albeit moderately. Study conducted across 1500 km coastline.
Main #biodiversity mechanism driving seagrass #biomass stock is through dominance.

Anna Vesanen on ammattisukeltaja ja vuoden alusta Tvärminnen eläintieteellisen aseman sukellusvastaava.
Merentutkijoiden kenttäkausi on vilkkaimmillaan huhtikuusta lokakuulle, ja silloin myös vierailevia sukeltajia on eniten asemalla.
Lue sukellusvastaavan terveiset! 👇

Kaunis kiitos tämän tarinan jakamisesta! <3
At the core of marine research - FINMARI Researcher Day - with many researchers from Tvärminne attending! A day filled with new knowledge about the ecological state, the effects of climate change, the green transition, and other current topics relevant to marine research in the Baltic Sea.
Tv-vinkki! Tänään 25.2. klo 18.30 YLE Fem tai Yle Areena. Dokumentti "Havsforskarna-Merentutkijat" kertoo tutkijapariskunnan Alf ja Joanna Norkon työstä Tvärminnen eläintieteellisellä asemalla aikana, jolloin huoli yhteisestä tulevaisuudestamme on vahvasti läsnä.
#merentutkijat #havsforskarna
Tiede tutuksi! Talvilomatorstaina 20.2. klo 11-15 Tvärminnen eläintieteellisellä asemalla järjestetään ohjelmaa koko perheelle. Levätyöpajan aikana pääset näkemään mikroskooppisen pieniä eläviä leviä, ja voit askarella oman leväsolun savesta. Katso koko ohjelma!
