PhD student in Benthic Ecology Team at Tvärminne Zoological Station, Finland
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.

🚨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! 🌊🔥

and the method here: doi.org/10.1002/lom3...

(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!

Out now: The cook book on how to simulate a #marineheatwave on the seafloor 🔥
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.

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

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

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

Let's roll! #HOTBOX

What a gorgeous morning to go out and start sampling for #HOTBOX @Tvarminne

1/3 Temperature loggers near @Tvarminne show that the water was exceptionally warm during last winter. Temperatures for February were the highest ever recorded (ave 3.51°C; 3.3°C above the norm of 0.22°C)and March (ave 3.4°C), was only beaten by 1964. Not good records to break...
