Chairs and co-chairs

Johannes Karstensen

Physical oceanographer
Back to all chairs and co-chairs

J. Karstensen is a physical oceanographer (PhD 1999 at the University of Hamburg, Germany) and held postdoctoral positions at the Lamont Doherty Earth Observatory of Columbia University, USA, and at the University of Concepcion, Chile. Since 2002 he has been working as a scientist at the GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany. J. Karstensen’s main research interests are in the broad spectrum of processes controlling ocean circulation of mass and heat and other properties from the large scale to the submesoscale and with a focus on the subpolar and tropical Atlantic. He is involved in various committees to help overcome the limitations of ocean observations resulting from the fragmentation of approaches to sampling strategies, sensor handling and standardisation, and data quality control procedures. He is the outgoing chair of the IOC Ocean Best Practices System and co-chair of the OceanSITES Eulerian time series network.
