Scientific Interests and Current Research General Scientific Interests Basic research is focussed on various aspects of coccolithophores but also include various topics of paleoclimatic evolution, in particular:
â€˘ Coccolithophores (species distribution and occurrences) for paleoceanographic and paleoclimate reconstructions through Plio-/Pleistocene time intervals.
â€˘ Morphometric study of intraspecific variation in various species (f.e. Coccolithus pelagicus) in sediment trap and geological samples.
â€˘ Quantitative and qualitative studies on carbonate budget; the effect of species composition and evolution on coccolithophorid carbonate accumulation.
â€˘ Transport and sedimentation of coccolithophores (and other biogenic carbonate particles) onto the seafloor and their accumulation in sediments.
In additon, my research also covers sedimentological topics (quantitative analyses of silt particles), and carbonate dissolution studies. Main working areas are in the Atlantic (i.e., the South Atlantic, eastern North Atlantic, and the Norwegian-Greenland Sea), but also in the upwelling regions off Chile and Somalia.
