@aquanorman.bsky.social presenting results of his awesome #heatwave experiments. @coastclim.bsky.social at the #OSM26 in Glasgow 🤓

I’ll be sharing our latest @coastclim.bsky.social results from an in situ marine heatwave experiment in the session Ecological and Societal Impacts of Marine Heat Waves at #OSM26.

Monday, 23 February 2026; 14:00 - 15:30 GMT
Scottish Event Campus; Room: Clyde Auditorium

Hope to see you there!

Our study made the cover! 😁
Proud to see our work featured on the latest issue of @funecology.bsky.social - Special Issue on Marine Heatwaves.

Had a great time at #EMBS58 hosted by #Norduniversitet in Bodø, Norway!
I presented our Hotfloor system and results from our @coastclim.bsky.social study how #MHWs affect biodiversity and ecosystem metabolism across a habitat gradient.
Thanks for an inspiring conference and fruitful discussions.

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.

🚨New paper out!🚨We show that #MarineHeatwaves amplify benthic metabolism and solute fluxes utilizing new developed #Hotfloor system-an in situ heating experiment.
No major community shifts, but big functional changes! 🌊🔥

Seasonal Variation in the Role of Benthic Macrofauna Communities for Ecosystem Functioning in Shallow Coastal Soft-Sediment Habitats - Estuaries and Coasts Coastal zones include a variety of habitats and numerous biodiversity components, which provide essential ecosystem functions and services. In the wake of the escalating climate and biodiversity crise...

New publication! Gammal et al. sampled benthic macrofauna, solute fluxes and environmental variables at 3 shallow habitats throughout one year.
Results show that the strength of biodiversity-function relationships really depends on which species are present in which habitat and during which season.

Finally in my hands! Graduated with distinction!🎓🌊🎉 Huge thanks to @dansmale1.bsky.social for an engaging defense discussion, my supervisors J. Norkko and @alfnorkko.bsky.social, and colleagues and supporters NottbeckFdn @coastclim.bsky.social RothFinland.

(Repost from twitter @asloorg.bsky.social 13.11.2023)💡 This #MethodsMonday researchers from
@Tvarminne in collaboration with #RothFinland introduce the new #Hotfloor system to simulate #marineheatwave on the #seafloor. This allows more realistic climate warming studies urgently needed (1/2)

Changing the perspective: So how extreme were the water temperatures this year? #extremetemp #marineheatwave
Depends on the reference period!

Simply rip out your underfloor heating and put it in a chamber! 😋

Here a sneak peak into some pictures and #underwater videos from our #Hotfloor setup and first day and night sampling! We were treated with an exceptionally beautiful calm and clear weather.
@Tvarminne @NottbeckFdn @helsinkiuni

Preparing to experimentally heat up the seafloor! The first pieces are “rolling” out for our next @CoastClim study #Hotfloor to investigate the effects of #MarineHeatwave on #benthic ecosystems
@NottbeckFdn @JoannaNorkko @anorkko @Tvarminne @helsinkiuni @cmgustafsson

Hey #ASLO23 are you curious about a newly developed method to investigate the effect of marine #heatwaves on benthic communities 𝙞𝙣 𝙨𝙞𝙩𝙪? Then come and check out our talk tomorrow on wednesday at 9:30 in the Auditorium Illes Baleares.

Importance of shifting baselines - be aware what reference period you use for assessing #climatechange! We investigate #extremetemp and sub-surface #marineheatwave using a 90-year #timeseries, now published in @CommsEarth.

One Year. 4 Season. 4 #MarineHeatwaves. Today starts the last round of our seasonal investigation. Here we will apply similar temperatures as in spring, so let's see what happens this time. @JoannaNorkko @LauraKauppi @anorkko @Tvarminne @helsinkiuni

Thanks @YleVastnyland for their interest in #MHW and #Warming of the #BalticSea.Great story about our pilot-study in cooperation with #RothFinland using a floor heating system to...well...heat the floor.This was only the start! ;-) @JoannaNorkko @anorkko @LauraKauppi @Tvarminne

Going out for our round Nr.2 of our #Seasonal #MarineHeatwave. A lot more enjoyable than our round in January 😅 @JoannaNorkko @LauraKauppi @anorkko @Tvarminne @helsinkiuni

Time to sample for a winter #Marineheatwave! I wonder who came up with that idea... 🥶😅

SIEVING TIME! 🍾
Finalizing our #HOTBOX round after we have exposed them to quite some #MarineHeatwaves @Tvarminne @helsinkiuni @JoannaNorkko @anorkko

3 days with #RVAugusta on the sea and now 4 weeks in our climate room! Let's see what a #MarineHeatwave does to our #Benthos! #Hotbox @Tvarminne @helsinkiuni @JoannaNorkko @anorkko
