Research Staff members Publications Lectures Contact		News from our working group Welcome to our homepage! Our research activities cover a broad spectrum of clastic and carbonate marine sedimentology, where we focus on the subjects "siliciclastic shelf systems" and "ocean and climate". In addition, our work is focused on the study of coccolithophores, including work on ecology, morphometry and biometry, as well as their application for different paleoceanographic studies and paleoenvironmental reconstructions. Last Activities 12.01.-14.02.2018 Research Cruise SO260, Argentina & Uruguay Participants: K-H Baumann, B. Kockisch, H. Lantzsch, G. Warratz Members of our working group participated research cruise SO260. The study area is the continental slope offshore Argentina and Uruguay.
