Fantastic! 24 talks in one day! 👏
UMF Symposium 2025 really highlighted the full diversity of what UMF has to offer—science, education, and services all showcased in one place.

Huge thanks to everyone who made it such a great day!

🌋Exciting! Cornelia Jansson & Morgan Jones run week-long #mesocosm experiments to see how volcanic ash (tephra) from Icelandic eruptions might add nutrients—or block light—in Baltic shallow marine ecosystems. 🌊🦑🧪

Restore #mangroves to capture carbon? Yes!🌱
100% positive? Maybe. Study shows that restored mangroves may not regain the ‘normal’ function of older forests. 🧪🦑🌊
