📢 Call for Abstracts – @egu.eu 2026 Join our session on VOCs at the Biosphere-Atmosphere Interface: From Molecular Mechanisms to Global Models🌱🧪🌐 🔗 meetingorganizer.copernicus.org/EGU26/sessio... @molteniu.bsky.social @wslresearch.bsky.social @riikkarinnan.bsky.social @voltcenter.bsky.social

This week we had the pleasure of hosting the @dg.dk annual visit to @voltcenter.bsky.social. As always, it was time to reflect on the success of the past year, and what a joy it was to relive all the highlights through @riikkarinnan.bsky.social's presentation!

Possibly the coolest PhD job available at the moment! ❄️❄️❄️Microbial VOC Exchange in Arctic Glacier Ecosystems❄️ ❄️❄️ 🌇Copenhagen, Denmark The supervisor team includes @alexanesio.bsky.social, Anders Priemé & @riikkarinnan.bsky.social employment.ku.dk/phd?show=165... Deadline 15 November 2025.

❗Job alert❗ VOLT is looking PhD students for 2 exciting projects, please apply or share with your network! #PhD fellowship in #microbial #Volatile Organic Compound exchange in #Arctic #glacier #ecosystems: employment.ku.dk/phd/?show=16...

The @voltcenter.bsky.social #hackathon is finally here! Everone is looking very focussed working on creative ways to achieve accurate, meaningful and beautiful #data #visualuzation!

Sometimes science is field work, sometimes it is lab work, computer work, discussions, presentations... and sometimes it is executing plan B and driving a highly sensitive and sophisticated scientific instrument across four countries and over 1500 kilometers! www.ionicon.com/blog/2025/a-...

Really enjoyed the annual @voltcenter.bsky.social retreat with great colleagues - two days of science, creativity, and connection. Great energy to carry into the rest of the academic year!

We just received a "postcard" from #Barcelona! @voltcenter.bsky.social's postdoc Cecilia Costas Selas and PhD student Eve Galen are attending the #SAME18 #aquatic #microbes #conference. Enjoy the sunshine and the talks, posters and discussions!

Last weekend, VOLT joined the #Fungi Festival🍄🍄‍🟫. Visitors got to hear a talk on hidden #fungaldiversity in #caves, and explored a collaborative booth. Here they could peek at fungal cultures under a microscope🔬, watch a short film highlighting the research, and learn about cave fungi and #VOCs.

🌲 Boreal-tundra species drive Arctic plant borealization 🌲 Our new study in #EcologyLetters quantifies tundra plant borealization, assesses its main drivers and identifies the species & traits contributing to borealization. doi.org/10.1111/ele.... 🧵 (1/6) 🌐🧪🌱🌍

Every year on week 37 @voltcenter.bsky.social goes away for two days of science, fun, inspiration and team building. Here are some of the many highlights in thread:

📣New paper📣 We measured #VOC & #CO2 fluxes from 3 ponds in a peatland forest using floating chambers. Understanding of freshwater ecosystems as VOC sources is poor, so this work led by Y. Qin, published in #ASLO_LO provides important new data. doi.org/10.1002/lno.... @dg.dk @voltcenter.bsky.social

Monday mornings are for breakfast journal clubs. 😋🤓 At @voltcenter.bsky.social we started the week with a discussion on #microbial #ecological strategies, led by postdoc Jonathan Donhauser.

Clean-up day at BIO!🧹 VOLT members came together to organize and clean our shared spaces 💻🔬🧪. With teamwork, enthusiasm (and cake!), we now have refreshed workspaces to support our projects.

#DHLrace day! The @voltcenter.bsky.social team is ready and in high spirits. Bring on those 25k per team! 🏃‍♀️🏃💨💪

Another late night in the lab… and between sampling points I made this inspired by my #Sphagnum #moss floating in my vials #uArctic_project #scienceart #midnightart @voltcenter.bsky.social

We are now (mostly) all done with holiday and field work, and we kick off being back in the office with a breakfast journal club hosted by postdoc Mehrshad Foroughan on new insights in #climate #science. How is your lab coming back into the swing of things?

Today we welcomed Professor Sándor Gonda from the University of Debrecen, for a guest talk on plant-microbe interactions at the plant metabolome level in horseradish. He shared interesting insights on a species that most of us had never studied before! 🌱

I am surprised, deeply honored, and thrilled to share I've been appointed as a Lead Author for the @ipcc.bsky.social Seventh Assessment Report (AR7 WGI)! I will be contributing to Chapter 4, "Advances in process understanding of Earth system changes" - a topic close to my heart.

📢 Exciting postdoc position in the @kathrinrousk.bsky.social group at @voltcenter.bsky.social 📢

Meet Mehrshad, a PostDoc at VOLT researching #VOC exchanges between the #ocean and the #atmosphere 🌊☁️. Using high-frequency measurements from a remote field site, he focuses on understanding how various physical and biological factors affect these exchanges.

This is my first time using a #PTR-TOF to track isoprene consumption over time… huge thanks to @voltcenter.bsky.social! 🤓 In the previous image, the black peaks represent #12C isoprene and the red ones show #13C isoprene. Concentrations are around 5–10 ppmv. 🏔️ spectra using 95% labelled 13C-isoprene

Director at Max Planck - a unique position! The Open Call for Expressions of Interest in Max Planck Directorships is open now and can be submitted by the 31st of October 2025. ➡️ mpg.de/directors - Please share the Open Call among potential candidates.

Peatland VOC flux measurements in the beautiful #StoreMosseNationalPark. Nice collaboration between @yijiao.bsky.social @voltcenter.bsky.social and @unpeatable.bsky.social. Funding from @villumfonden.bsky.social @dg.dk

Field season for team @voltcenter.bsky.social @riikkarinnan.bsky.social @dddwbbtl.bsky.social at #StoreMosse, southern Sweden’s largest active raised bog! We’re tracking how vegetation, water table, and microclimate shape #VOC exchange in #peatland, supported by #VillumFonden.

What a cool retro train or what do you think? #FieldWorkTravel in Sweden

The BBQ was preceded by a PhD mid-term talk by @martacontreras.bsky.social on the effects of #climatechange on #plant-produced #VOCs. It seems our PhD students have just started, and some are now 14 months away from finishing!

The sun is shining, and the field work and holiday season are here. But before that, we celebrate 1 more year of VOLT success with our summer BBQ. This time, with a very special guest, collaborator @noahfierer.bsky.social!

This looks cool... sorry... HOT!

Amanda Ammentorp Pedersen did a fantastic job discussing her MSc project at the thesis defence held this week. Amanda's work focused on how Salix herbacea responds to climate warming along a snow melt gradient in Greenland. Stay tuned for a publication later. :) @voltcenter.bsky.social

A PhD defense starting and I'm in the evaluation committee. I don't know the two other committee members. And suddenly I realize I haven't even read the thesis. I really need to go to the toilet when the defense starts–and I can't find the way back to the auditorium. Time for vacation, right?

@voltcenter.bsky.social wrapped up the 1st International Symposium on Volatile Interactions in Ecosystems in Copenhagen! Special moment for me presenting my work on #uArctic_project isoprene cycling, following the plenary talk & footsteps of my mentor Colin Murrell www.linkedin.com/posts/nasmil...

Great start of the last day of the 1st International #Symposium on #Volatile #Interactions in #Ecosystems with a keynote talk by Colin Murrell from the University of East Anglia. This may be his last scientific talk now that he will enjoy his retirement, so it is extra special to have him.

Thanks so much to @voltcenter.bsky.social, @riikkarinnan.bsky.social and everyone involved in organizing the PhD course on BVOCs and the Symposium on Volatile Interactions in Ecosystems. Great to be part of the discussions in Copenhagen! 🇩🇰

New learning opportunities with nice people at the "1st International Symposium on Volatile Interactions in Ecosystems" in Copenhagen🇩🇰 Thanks to @voltcenter.bsky.social @riikkarinnan.bsky.social

The first full day of talks and networking of @voltcenter.bsky.social's 1st International Symposium on Volatile Interactions in Ecosystems is in full swing at beautiful festauditoriet in #Frederiksberg, with a fantastic #Aquatic #Ecosystems session in the morning! eventsignup.ku.dk/voltsymposiu...

After our registration and welcome talk by @riikkarinnan.bsky.social last night, we are at the first day of talks for the ‘1st International Symposium on Volatile Interactions in Ecosystems’. 🤩 1st plenary speaker is Kimberly Halsey @oregonstate.edu ‘Investigations on the microbiology of VOCs’ 👏🏾👏🏾👏🏾

@voltcenter.bsky.social joining the 1st VOC symposium arranged by @riikkarinnan.bsky.social and many more. It is in one of the most beautiful auditoriums at @ucph.bsky.social

Day 2 of the PhD course organized by @voltcenter.bsky.social and funded by the Faculty of Science @ucph.bsky.social is in full swing. Yesterday, there was a mix of introductions, lab tour and a scents tour at the botanical gardens. Today we delve into the scientific programme.

We are hosting a PhD course on volatiles in ecosystems for 30 international PhD students. Today we heard flash talks by all participants, got an introduction to isotopes, a lab tour and a tour in the Botanical Garden of #SNM. We are thankful for Faculty of Science @ucph.bsky.social for funding.

It was a pleasure to visit @uofglasgow.bsky.social Plant Science symposium to give a talk about our work with plant volatiles in Arctic ecosystems. Learnt a lot and enjoyed the exceptional sunny weather not so common for Scotland.

Today's talk at @voltcenter.bsky.social was on #marine #atmospheric #VOCs and fluxes in the #Baltic #sea by Mehrshad Foroughan.

Meet Eve, a PhD candidate at @voltcenter.bsky.social working with marine microbial volatiles, bacteria and #phytoplankton. Her research combines large-scale marine environmental studies with lab experiments on bacterial cultures 🦠🌊

The first decision each morning: Which @voltcenter.bsky.social coffee mug to choose today? Plant, soil, or water?

Cool #science alert! “In this paper, we have compiled our current understanding of MVOCs in extreme environments. I hope that this review can serve as a starting point for anyone interested in this topic.” - @masalgar.bsky.social #FEMSmicroBlog @dg.dk fems-microbiology.org/femsmicroblo...

Proud of MSc Toke Sjøgren from @voltcenter.bsky.social, who brilliantly defended his MSc project on plant VOCs from common European trees under heat and ozone stress. Toke was co-supervised by @evayp.bsky.social from @fz-juelich.de. All the best with your future endeavors, Toke!

#EGU25 was amazing! Will take some days to recover from the science overload. I truly enjoyed listening to inspiring talks and checking out posters. The great debate on methane. A few jogs by the Donau. Met many old and new colleagues and friends. Missed at least as many... Until next time!
