Video: How we take soil samples for soilwater analysis
For my PhD thesis we will drill 500+ holes and take over 6000 soil-samples. Here you see our process:

Communicating Science through Social Media
This week I took part in a Workshop by Sascha Vogel (https://sciencebirds.de/) learning how to communicate science using social media. Especially the discussions on (mis-)use of social media to promote fake news and on the responsibility of scientists to communicate their work really stuck with me. It was a well structured course where we first…

Field Campaign in the Alps
The final field campaign took us to the most scenic but also coldest and steepest catchment of our research project. We spend the last September weeks in the “Padaster”-Catchment close to Innsbruck in Austria. Our first day started with a snowy greating and clouded mountains, however the sky cleared and sunshine revealed the most atonishing…

Autosampler for Isotopes
After multiple iterations, the autosampler finally works. While I assembled the hardware, Stefan Seeger did all the software programming and designed the PCBs. Our System currently has the capacity to load 46 sample bags. The samples are each pricked with a cannula which is connected to a valve. The valves can individualy be opened, allowing…

Field Campaign Sauerland
The last week of July was the fieldcampaign in Sauerland where we also dug three trenches for Subsurface Flow Measurement. This time we chose a mixed forest, clearcut and pasture site. Upslope of the trenches we also drilled soilcores and sampled eDNA, water-soluble organic carbon and water stable isotopes in different soil layers. Per Trench…

Water Stable Isotope Measuring
After taking over 700 soil samples in the Freiburg fieldcampaign, I am now analyzing the soil water stable isotope composition. Therefore the sample bags are inflated with dried air and heat sealed. After 48 hour equilibration time, each bag gets tested. Therefore, the bags are pricked with a needle and tube, leading to a PICARRO…

EGU 2022
In May I virtually joined the “European Geoscience Union 2022”, attending multiple Short Courses and listening to lots of interesting presentations from fellow scientists. I was also able to present my masterthesis titled “Assessing Climate Impacts Against Groundwater Pumping Impacts on Stream Flow with Statistical Analysis” in the Session “Groundwater-surface water interactions: physical, biogeochemical and…

Field Campaign Freiburg
Last Month I started my Phd in the DFG funded “Research Unit Subsurface Stormflow” with a joint Field Campaign. We excavated multiple trenches and installed drainage-mats. Flow caught on these mats funnels into pipes which will run into tipping buckets, allowing us to measure subsurface flow amounts. To monitor subsurface flow on the catchment scale,…
