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 ....

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

Special Feature: Marine Heatwaves: Functional Ecology: Vol 39, No 8 <em>Functional Ecology</em> journal publishes high-impact research providing a mechanistic understanding of ecological pattern and process from the organismic to ecosystem scale.

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?

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 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.

'You look up and see light coming through': The divers venturing under the ice in the name of science It is a world cut off from our own by thick blankets of floating ice, but some scientists are taking the plunge to learn how these frozen depths are changing.

Happy to share this article about our science and polar diving published on bbc.com!
