Daniel Pönisch

Senior Scientist Peatlands

Since December 2023, Daniel Pönisch has been an employee of the Fraunhofer IGD with a focus of applied research on topics of peatland rewetting and greenhouse gas release and is the senior scientist of the project “Valuation of ecosystem services of peatlands”. He is involved in the development of the research focus “Peatlands” at the IGD. As part of the project, he coordinates the topics of the sensor-based and automated determination and evaluation of real-time field data, the water level and vegetation-based estimation of greenhouse gas emissions from peatlands and digitization-related topics.

 

PhD (Leibniz Institute for Baltic Sea Research Warnemünde)

He accomplished the PhD at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) in the field of marine chemistry. The focus was on the marine carbon cycle in the shallow waters of the Baltic Sea and the release of climate-relevant trace gases from peat sediments and coastal peatlands. High-resolution multi-sensor measurement platforms were developed and used for the biogeochemical observation of the temporally and spatially highly dynamic processes. The work was carried out as part of the DFG Research Training Group Baltic TRANSCOAST, which enables interdisciplinary research at the interface between the marine and terrestrial ecosystems.

Daniel Pönisch studied chemistry (B.Sc.) at the Technische Universität Dresden and chemistry (M.Sc.) at the University of Rostock.

 

Research interests

  • Greenhouse gas dynamics and release in marine environments and peatlands
  • Environmental monitoring and biogeochemical in situ sensors (e.g. CO₂, CH4, CTD, O₂, chlorophyll a, PO43-, water level)
  • Development and use of multi-sensor measurement platforms for autonomous recording of biogeochemical variables

Wetlands research

We connect scientific findings and data from fundamental research with in-situ sensor technology and AI-powered drone image analysis to improve moorland management.

 

Valuation of peatlands as CO₂ stores

In our VALPEATS project, we are developing AI-based monitoring tools for the objective valuation of ecosystem services
