Our team elucidates the structure, origin, transformation, aggregation, ecological function and distribution of organic compounds in the changing polar ocean.

We aim to understand the function of marine organic compounds, both, as diagnostic markers to decode biogeochemical processes and as drivers of chemical interactions between species.

Organic molecules

  • render or result from important physiological processes of polar organisms, e. g. during photosynthesis, nutrient acquisition and storage of energy.

  • orchestrate species interactions affecting organismal abundance, physiology, performance, resilience and adaptation.

  • represent fingerprints of organic matter transformations and can thus serve as biogeochemical proxies.
