Heavy surface layer floats on top

A gossamer pellicle, frequently observed on marine surfaces, often is more saline than the underlying bulk water in the tropical Pacific, despite the fact that regional freshwater input by precipitation surpasses evaporation. This is what marine scientists from Oldenburg, Germany, report in an international study, together with their colleagues from Florida State University and Columbia University in the U.S. more

Among the Most Cited Scientists: Thorsten Dittmar and Helmut Hillebrand

The recent ranking names two ICBM scientists among the global list of „Highly Cited Researchers“: While ICBM research group Planktology head and founding director of Helmholtz Institute for Functional Marine Biodiversity at the University of Oldenburg, Prof. Dr. Helmut Hillebrand, continues to be listed, the head of the research Group Marine Geochemistry (ICBM-Max Planck Institute for Marine Microbiology Bridging Group), Prof. Dr. Thorsten Dittmar, is listed for the first time in the ranking, determined by an analysis of citations in Web of Science by the company Clarivate Analytics. According to one of the company's statements, “the Highly Cited Researchers list represents some of the world's most influential minds“.

Melanie Behrens awarded Junior Fellowship

Dr. Melanie Behrens, staff member of Max Planck Research Group for Marine Isotope Geochemistry at ICBM, has successfully applied for an Associate Junior Fellowship of the German Hanse-Wissenschaftskolleg – Institute for Advanced Study (HWK), Delmenhorst. The fellowship includes, amongst others, the possibility to bring together up to eight project partners from inland and from abroad for a one-week retreat at HWK.
