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.

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.

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.
