While our EC Flux measurements close to Alnarp are only in their 3. year, our neighbors and collaboration partners at SITES Lönnstorp & SLU have done research on #Kernza for over 10years. #perennial #perennialrevolution @thelandinstitute.bsky.social @beccsweden.bsky.social @fieldsites.se

At SITES Lönnstorp Research Station, trials with the perennial wheatgrass, Kernza, have been running for more than ten years. Learn why Kernza research represent a potential revolution in agriculture 👉https://www.slu.se/en/news/2026/06/researcher-on-perennial-wheatgrass-part-of-a-new-revolution/

Tobias and Peter at 35 meters, casually chilling above the planet, doing EC flux maintenance like gravity is merely optional, all while keeping safety front and center. Respect to the colleagues who bring precision, calm and expertise to every task, no matter the height. @beccsweden.bsky.social

Another intake up! Hopefully we'll soon have BVOC/CH4/CO2 EC Flux, CO2/CH4/O3 profile & subcanopy CO2 EC & CO2/CH4 soil/trunk chamber measurements. Note the @icos-ri.eu 30m CO2 EC Flux & 150m GHG profile setup in the background @icossweden.bsky.social @beccsweden.bsky.social @lufluxes.bsky.social

LU Fluxes and the Perennial team spent two scorching days at Borgeby Fältdagar, one of northern Europe’s biggest agricultural fairs. Great conversations, sharp questions, and a surprisingly strong interest in perennial crops. The momentum is building. @beccsweden.bsky.social

And another day enjoying the sun above the canopy! Getting our BVOC Eddy covariance system ready for summer. @icossweden.bsky.social @lufluxes.bsky.social @lund-university.bsky.social @beccsweden.bsky.social

Who needs a beach if you have a mast and can take a sunbath above the canopy? Did some maintenance on the #ICOS Flux system while we were up there. @icossweden.bsky.social @icos-ri.eu @fluxnet.bsky.social @lufluxes.bsky.social @beccsweden.bsky.social @lund-university.bsky.social

Started our vegetation sampling following the ICOS‑protocol for croplands today. Veronika and her crew worked nonstop; collecting in the field, processing in the lab, and keeping the whole operation moving. Couldn’t ask for a better team. @beccsweden.bsky.social

Kernza keeps climbing, so we adjusted EC measurement height again and did the usual tower maintenance. The local birds, however, remain convinced our rain gauge is their premium restroom. Field techs by title, restroom attendants by circumstance. Kudos to the crew @beccsweden.bsky.social

Spring barley is shooting up fast at our reference field, so it was time to bump the measurement height again. Peter added a round of routine flux tower maintenance while he was up there. Field season never slows down. @beccsweden.bsky.social @lund-university.bsky.social

Up in the mountains, the crowberry is flowering. 🌸

Another heat wave is hitting Europe. June started hot & will continue to be so. While not as scorching hot here in Southern Sweden the average temperature has increased rapidly in the last 20 years, seen in the climate stripes for CPH. #showyourstripes @edhawkins.org showyourstripes.info

Extreme Temperatures Around the World@extremetemps.bsky.social · 2mo ago

It's hard to fathom what Europe will live next week. Thousands of records will be brutalized in Spain,France,UK,Benelux,Germany,Swiss,Austria and than the East Paris might record 4 consecutive days 40C UK will ridiculize its June national record Germany 10 days 37C+ This is CRAZY

Historic #heatwave underway in #Europe! Peak highs upto 45°C , 100-115F!! #France may near an all-time national record. 1000s of daily and June records will fall. Western Europe is one of the fastest warming land areas, and is experiencing some of greatest growth in extreme heat as the climate warms

Meet Theodora, our Erasmus intern joining us from Thessaloniki. She’s jumped straight into the action, installing sensors and collecting N₂O emission data in our ley trials. Excited to see her work unfold. @beccsweden.bsky.social @lund-university.bsky.social

Fieldwork Friday: Tobias and Peter have been busy updating EC measurement heights across both crop systems in Alnarp to account for increased canopy height. Completed routine maintenance on sensors and other infrastructure. @beccsweden.bsky.social @lund-university.bsky.social

Interesting first day of the Swedish Climate Symposium in Lund. Great speeches and posters. Looking forward to tomorrow's exciting program. @beccsweden.bsky.social @lund-university.bsky.social

Yesterday, the Swedish Society for Anthropology and Geography awarded our former colleague Mitro Müller the Alfort Prize for best thesis in physical geography in Sweden during 2025, at a ceremony held at the Royal Swedish Academy of Sciences. Well done, Mitro! Proud of you! @beccsweden.bsky.social

At SSAG’s Vega Day Symposium for Vega Medalist Johan Rockström in Stockholm tiday. His “Update of the State of the Planet” talk was powerful - inspiring, sobering, and a reminder of how much work lies ahead to keep us in a "planetary safe space" @beccsweden.bsky.social

🎉 Congratulations to Anne Klosterhalfen, postdoc at U. Göttingen and scientific coordinator of ICOS Hainich station, on receiving the #EGU26 Biogeosciences Outstanding ECS Award! Anne's work on ecosystem carbon fluxes is the kind of science that makes the ICOS community shine👏

Experienced researchers are less likely to produce ‘disruptive’ science than are those just starting their careers, finds an analysis of the scientific papers published by 12.5 million researchers over 60 years. go.nature.com/4uUvMk3

Early-career researchers do more ‘disruptive’ science than veterans

Analysis of papers from millions of scientists shows that older researchers tend to stick with ideas from their past.

Our Erasmus interns, Clara and Clémence, are getting hands‑on with LAI measurements today. They’re practicing with our LI‑2200TC at campus before heading out to our forest and agricultural sites for the real data collection. Great to see their curiosity in action. @beccsweden.bsky.social

At SITES Skogaryd today: Matilda and Stig chasing methane and nitrous oxide fluxes through forest soils and tree stems. Every measurement adds another piece to the puzzle of how forest landscapes interact with the atmosphere. @beccsweden.bsky.social @fieldsites.se

Big day in the field. We’ve officially started our project to rewet organic ag soils for climate action and restore the soil for future food production. Huge shout‑out to Stig, Peter, and our French interns for installing groundwater wells and GHG collars like champs. @beccsweden.bsky.social

Key takeaway: Natural carbon sinks are more cost effective than technological ones. Management can influence natural carbon sinks🌲 www.sciencedirect.com/science/arti... www.sciencedirect.com/science/arti... @icossweden.bsky.social @hyytiala.bsky.social @helsinki.fi @lufluxes.bsky.social (2/2)
