Very proud of Antonia Klatt, who did an excellent job defending her PhD thesis yesterday. Toni is the first PhD from our Uni Basel Organic Geochemistry group, and has been a joy to work with over the past four years. Can't wait to see what she accomplishes next!

In a central European context, correcting plant wax d2H values with a simple index based on the relative abundance of different n-alkanes seems to do the trick, allowing us to get reasonable estimates of past precipitation isotopes during times with big ecological changes

How can we best correct for vegetation changes when reconstructing precipitation hydrogen isotopes from plant waxes? @ricardoansantos.bsky.social answers this question with sediments from Rotsee, our favorite little lake

Can we use H isotope offsets among lipids as proxies of algal community composition? New paper led by Antonia Klatt shows that changes with community throughout a year in Rotsee aren similar results from cultures and indicate minimal influence from heterotrophs: doi.org/10.1016/j.gc...

Call for abstracts #EGU25 on developing new biomarkers! #EGUbiomarker. Abstract submission is now open! Organized by Jingjing Guo, @hallbergpetter.bsky.social, Nora Richter, Addison Rice and myself. tinyurl.com/4422wwr7

Screenshot of the following text:
Lipid biomarkers: novel applications, calibrations and tools for environmental
studies
Lipid biomarkers are valuable tools for reconstructing a variety of environmental processes in modern
and (geological) past settings. We seek studies that develop new lipid biomarkers and methods for
applying biomarkers to modern settings and the geologic past to reconstruct environmental
parameters such as temperature, precipitation, biogeochemical cycles, anthropogenic activities, and
vegetation. These can be studies on the biosynthesis and phylogeny of source organisms, transport and
diagenesis, calibrations to environmental parameters, proxy interpretation and applications to reconstruct past environmental conditions.
