My research interests concentrate on the role of the large-scale ocean circulation in climate and climate change. Predicting climate throughout this century and beyond requires, first, that the important physical and chemical processes are well understood and can be simulated accurately; second, the current climate - in particular its oceanic component - must be known with sufficient accuracy to provide initial conditions for climate predictions. Both demands pose a formidable challenge, and combined have dominated my research agenda.

Meridional transports of mass and heat are the premier manifestations of the role that ocean dynamics play in climate - heat transport reduces meridional temperature gradients; mass transport accomplishes heat transport. An example is the northward heat transport in the Atlantic by the thermohaline circulation (THC, driven by surface heat and freshwater fluxes), but there exist important wind-driven transports of mass and heat in the ocean. Throughout the years, almost all of my research has been devoted to the fundamental understanding of meridional oceanic transport processes and how they interact with other components of the climate system.

My most ambitious current research direction can be summarised under the “Abrupt Climate Change” umbrella. Applied to the Atlantic, Abrupt Climate Change means the possibility of disruptions of the current THC pattern. Predictability and prediction of the THC are of enormous societal relevance, but also pose fundamental scientific questions. These force us to combine observational, theoretical, and numerical work in the ocean, to synthesise data through models, and to investigate interactions with the atmosphere. The 1990s had seen a tremendously successful love affair between idealised physical oceanographic modelling and palaeo-oceanographic observations. When it comes to dealing with the future evolution of the THC, a similarly successful symbiosis is needed between observations of the modern ocean circulation and realistic ocean modelling. I led the UK effort to establish the national programme RAPID, funded with £20 Million over six years and focussing on exploring the role of the Atlantic THC in rapid climate change. Within this programme, I was the Lead P.I. of a £4 Million project to observe, for the first time on a continuous basis, the Atlantic THC (more precisely: the meridional overturning circulation, MOC; see http://www.soc.soton.ac.uk/rapidmoc). This involves intensive fieldwork, aided in its design by numerical modelling. Since leaving the UK I have still been actively involved in this project, including its seagoing activities. At MPI-M, I am now contributing to the Abrupt Climate Change questions through advanced coupled modelling, for example by exploring the influence of a melting Greenland ice shield on the THC or the effect of THC changes on European climate. I contributed to the 2002 panel report on Abrupt Climate Change by the National Research Council of the U.S. National Academy of Sciences, and I was the lead organiser of the 2003 Royal Society Discussion meeting on Abrupt Climate Change.

At the University of Hamburg, I teach a graduate-level course on Climate Dynamics (S_36, here) during the summer semester. I also teach a graduate seminar, Generic Academic Skills, during the winter semester (S_39, here). Together with Dallas Murphy, an author from New York City, I teach the workshop Advanced Scientific Writing (S_41, here), as a week-long block course in February.

I co-taught the graduate seminar, The Roles of Conceptual Models (Theory) in Building Knowledge (15.526). The lecture on the interplay of simple and complex models of the THC can be found here.

Courses at SOC: I developed a course on Climate Dynamics (now SOES6006), directed at 4th-year undergraduates and M.Sc. students. Detailed (albeit outdated) information about this course can be found here. I also developed and coordinated a hands-on modelling course, Modelling in Environmental and Earth System Science (now SOES6002), which in turn was designed after the Geosystems course that I co-developed and co-coordinated at MIT.

Oxford Spring School Lectures: Notes from lectures on adjoint sensitivity calculations can be found here.

Cambridge University GEFD Summer School: Notes from lectures on thermohaline circulation dynamics can be found here (rudimentary but with extensive references).
