On March 20, 2025, many happy faces could be seen at Allende-Platz in Hamburg's Grindel District. Right in the middle of it all was Friederike Neiske, receiving warm congratulations under the radiant spring sun from family, friends, and colleagues from the RTG 2530 and the Institute of Soil Science (IfB). Just moments earlier, she had successfully defended her doctoral thesis at the IfB on the topic "Soil Organic Carbon Dynamics along Estuarine Gradients".

Always a special moment - the presentation of the doctor's hat. The tea bags attached to this creatively designed one symbolise Friederike Neiske's extensive research work on the Elbe estuary: using the so-called tea bag index, she investigated, among other things, how organic material in marsh soils decomposes over the course of the year under the influence of salinity and hydrological conditions. She used about 3,600 green and rooibos tea bags, which were carefully buried in various locations and at different times, and then dug up, dried, and weighed again after 90 days.
