Even by teaching chemistry to geoscientists, ORCAS member Marcus could score with well-structured and comprehensible lecturing, which is why the students rewarded him with the popular golden hammer. The second and third places went to Frank and Philip. Congrats to all of you!

An emotional moment: the work has been very much supported by my dear friend John T.G. Hamilton who died in 2022. Radical-Driven Methane Formation in Humans Evidenced by Exogenous Isotope-Labeled DMSO and Methionine mdpi.com/2372736 #mdpiantioxidants via Antioxidants MDPI

After a three-year break due to COVID, we finally revived our group-barbecue tradition, which was a full success. Thanks to all participating ORCAS for making this a very entertaining and special event! #socializing #collegiality

That lunch break was fun! We felt highly inspired by Women's World Cup today!

Celebrating a great achievement in our research group! Marcus earned his PhD with summa cum laude, studying the environmental relevance of climate-active and ozone-depleting gases derived from intraplate volcanism🌋. Warmest Congratulations from all of us! #PhD #gasanalytics

Enjoying the beautiful Old Town of Heidelberg with our Japanese friends Kosuke and Fuka from Sakai lab in Kyoto!

Our group was well represented at this year's #GASIR meeting in Bayreuth! We had a great time exchanging ideas on exciting projects in the field of stable isotope research. Looking forward to future collaborations ahead!

With her amazing research on breath #CH4 levels affected by immune responses, Daniela received the Best Poster Award at this year’s Breath Biopsy Conference! Curious? See for yourself: support.owlstonenanotech.com/hc/en-us/commu…

Proud moment for our group! Prof. Dr. Frank Keppler received an honorary doctorate by the University of Szeged, Hungary, for outstanding scientific contributions and long lasting collaboration with the Institute of Surgical Research at Szeged University. #ScientificExcellence

Our #biogeochemistry research expanded into #geology, and it paid off! Johannes and Marcus earned our institute's geology prizes for outstanding work on gas composition in magmatically altered salt rocks during their bachelor's and PhD studies. Congratulations!

Cheers to Daniela, Jonas, Moritz, and Markus for their exceptional publications as first authors, rewarded with Orcas according to our group's favourite tradition! Wishing everyone a joyous Christmas filled with warmth, success, and festive spirit!🎄

Turning our commitment to #sustainability into action, our group and fellows of the Institute of Earth Sciences took part in a joint cleanup effort. Together, we contribute to a cleaner and more eco-conscious workplace. 🌏 #EnvironmentalAwareness #CleanUpDay

Inspiring day with Prof. Sakai from Kyoto University, from German-Japanese knowledge exchange to delightful strolls through the Old Town! Strengthening ties and sharing experiences across borders. 🌍🔍

Our Master’s fieldtrip offered a deep dive into #biogeochemistry in the #Anthropocene. A big thank you to our enthusiastic students and our collaborators at each facility for sharing their expertise and for making this a truly special experience! #EnvironmentalResearch

Greetings from Helgoland! We're excited to be on RV Heincke in the North Sea, joining the EduCruise from #AWI and #Polmar, instructing #CH4 analysis in seawater using our #PICARRO system. Many thanks to Gernot Nehrke for inviting us and giving us this great opportunity!

Moritz, Manuel and Rebekka experienced an amazing stay at Sakai-sensei's microbiology lab in Kyoto, exploring microbial methods while enjoying Japanese culture, cuisine and sports. Big thanks to the lab members for their warm hospitality and shared expertise!🇯🇵🌿#ScienceExchange

Celebrating Laura, Kai and Axel for their "Heinz-Friedrich Schöler Award" wins! Outstanding theses in environmental research!🌍 Congrats!🎉

Our group had a great time at this year's GASIR meeting in Darmstadt with fascinating talks, engaging discussions, and we're proud to announce Maurice's win of the poster prize for his isotopic investigation of plant-part specific N2O production in chicory!🌿 #Isotopes

Celebrating ORCA's 10th anniversary in Dinkelsbühl, Bavaria! Gained new perspectives at the forest climate station, enjoyed local food & drinks, and explored the historic Oldtown - it was a memorable milestone!🌲🍻

Big cheers to Anna for earning her PhD on tree #methoxy isotope ratios and their potential for metabolic and climate research!🎓 Your roots in our group run deep, and we'll miss your scientific brilliance and humor. Here's to growing into exciting new adventures!🌳
