The main topics of the “Marine Chemistry” group are:

  • chemical characterisation and flux studies of organic matter in the ocean with special emphasis on the dissolved fraction.
  • Composition of lipids occurring in the marine environment, especially in zooplankton from tropics to high latitudes.
  • Tracing phytoplankton derived carbon through higher trophic levels with bulk & compound specific stable isotope analysis.
  • Determination of nutrients in all oceanographic regimes in connection with plankton development and as hydrographical tracer.
