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!

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!

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:

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.

📣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.

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.

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.

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.

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.

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!
