Very happy that our big paper on regional drivers of Nordic salt marsh carbon stocks from the NordSalt project is now published. Great work by former postdoc Anais Richard: bg.copernicus.org/articles/23/...

Livestock grazing, plant community and abiotic factors shape blue carbon stocks in Nordic coastal marshes
Abstract. Coastal marshes are key habitats contributing to organic carbon (OC) storage but remain understudied in Nordic regions regarding Blue Carbon processes. This study quantified OC stocks in abo...

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️... Turns out that 2/3 of these assertions are very wrong... 🌐 🦑🧪 🧵⬇️
