Sabrina Speich


Sabrina Speich is Professor of Ocean, Atmosphere and Climate Sciences at the Department of Geosciences of Ecole Normale Supérieure in Paris, France and at the Laboratoire de Météorologie Dynamique of the Institut Pierre-Simon Laplace (IPSL). She studied Physics in Italy at the University of Trieste (Italy), at CERN in Geneva (Switzerland). She received a PhD in Physical Oceanography from UPMC Paris VI (France) in 1992. She was assistant researcher at the Department of Atmospheric Sciences at University of California, Los Angeles (UCLA, USA) from 1992 to 1994 and at CNRS (Paris, France) in 1995. She then became Professor at the University of Brest (France) where she worked until 2013. She was invited Professor at the University of Cape Town (South Africa) in 2001 and 2003.

Prof. Speich' research interests concern the uncovering and understanding of ocean dynamics and its role on climate variability and change. She is a world-recognized expert in ocean modelling as well as in organizing wide programs of in situ observations. She is recently focussing her research on scale-interactions in ocean dynamics, and how they affect the global ocean circulation, air-sea exchanges and ecosystems under a changing climate. She pioneered the use of Argo floats to observe the ocean.


Johannes Karstensen

I am an observational physical oceanographer and made my PhD in 1999 at the University of Hamburg, Germany. I did a Postdoc at Lamont Doherty Earth Observatory of Columbia University, USA, and at the University of Concepcion, Chile. Since 2002 I am a researcher at the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany.

My research interests are related to the broad range of processes that control the large-scale circulation of mass and heat and other properties in the ocean. I am in particular to investigate the complexities of the processes by making use of a broad range of observations – from large (1000s of km)- to sub-mesoscale (<1km). At present my main emphasis of research is on understanding the mechanisms that are responsible for changes in Subpolar North Atlantic properties and water masses, e.g. in response to large-scale climate modes, such as the NAO and Atlantic Decadal Variability. Moreover, I am working on transport and mixing processes associated with ocean mesoscale eddies, also considering possible feedback mechanism between physical and biogeochemical processes.

Being a member of the scientific expert advisory group of the Ocean Observations Panel for Climate (OOPC) and by contributing to the development and testing of new ocean-observing techniques I also consider in my work several aspects of optimizing ocean observing.


Anke Schneider

I am a chemical oceanographer currently working at Kiel University. I studied „Marine Environmental Sciences" at the University of Oldenburg and graduated in 2004, after spending 8 months at the Southern Cross University in Lismore, Australia, for the preparation of my thesis. Starting in 2005, I worked in the Marine Biogeochemistry department at the GEOMAR Helmholtz Centre for Ocean Research Kiel and finished my doctorate in 2011, followed by a Postdoc. In my research I focused on the carbonate system and ventilation processes in the Mediterranean Sea and the tropical Atlantic Ocean. I used oceanic tracers (CFC-11, CFC-12, SF6, tritium) and the transit time distribution (TTD) method to determine water mass ages and to estimate anthropogenic carbon concentrations.

At present I am coordinating specific research topics in the framework of the Excellence Cluster "Future Ocean" at Kiel University, which concentrates on understanding the ocean, on identify potentials and risks and on a sustainable development. I am in charge of organising international workshops and meetings, planning lecture series and developing outreach and capacity building acitivities.
