The #alga #Melosiraarctica, which grows under #ArcticSea ice, contains ten times as many #microplastic particles as the surrounding #seawater. This concentration at the base of the #foodweb poses a threat to creatures that feed on the algae at the sea surface. Clumps of #deadalgae also transport the #plastic with its #pollutants particularly quickly into the #dee sea & explains high #microplastic #concentrations in the #sediment there. https://phys.org/news/2023-04-arctic-ice-algae-heavily-contaminated.html
