Great start to 2026 and the final year of my PhD with presenting in #PAM26! 🦠🧪

Great to see the final formatted version now published. @neatuomela.bsky.social led a concept-chllenging study about how thawing/degrading #permafrost palsas do not necessarily result in organic matter and the associated bacteria reaching the connected waters Link: academic.oup.com/ismecommun/a...

Carbon and microbes in a degrading palsa mire are distinct from a peatland and a wider connected sub-Arctic fluvial system

Abstract. Climate change is altering the biogeochemical cycling of carbon and nutrients in the northern peatland and permafrost regions, which provide two

Final format of my first article is now out! We discovered that degrading palsa permafrost might not lead into higher loading of organic matter into the river system. Also, we discovered that microbial communities were dominated by ultra-small Patescibacteria 🦠

First paper from Nea’s PhD is out! DOC and ultra-small bacteria in thawing palsa and palsa ponds. In 2026 the focus will be on those ultra-small microbes 🦠

Saturday #arctic palsa fun for Arctic Ecosystems research team from ⁦@helsinkiuni ⁦@BioEnvHelsinki⁩ in Kevo, Brandy-coloured waters and frozen palsa soils…..what more could we wish for

New Book Day 🎉 🥁🥁🎉 Although published online last month the hard copies of Sea Ice 4th Edition arrived this morning. 🧵(1 of 2)

Thrilled to present a poster in #FEMS2025 Milan! Find me today at Poster Area A21 to learn about microbes and carbon in a river system affected by permafrost and peatland 🦠

2nd of May vs 30 May high on a fell near Utsjoki looking towards “our” ( @neatuomela.bsky.social ) palsa mire site

Colour of a palsa mire (permafrost) “waking up” just days after the snow has disappeared

@neatuomela.bsky.social and Anniina Haverinen getting to grips with early season (i.e cold) palsa-mire water sampling

Carbon and microbes from thawing palsas and peats do not reach a wider fluvial system https://www.biorxiv.org/content/10.1101/2025.05.07.652394v1

Super happy to see this is now available.....I am hugely biased of course, but ⬇️ is highly pertinent for the discussions about rapidly thawing #Arctic inland permafrost systems
