Research interests

Research interests are in Earth System Modeling, Theoretical Oceanography and Meteorology, and in the field of Dynamical System Theory. One focus of my research is to identify driving mechanisms for paleo and future climate change. This is done through numerical models of the Earth system and statistical analysis of instrumental and proxy data. One special area of my research is focussed on the role of the global oceanic thermohaline circulation for recent and paleo climate variations. The identification of resonances and thresholds in the system allows an estimate of possible future climate shifts.
 
Further research interests are in Earth System Modeling, Paleoclimate Variability, Theoretical Oceanography and Meteorology, and furthermore, in the field of Dynamical System Theory and Applied Mathematics. Recent work focusses also on the statistical interpretation of proxy data, e.g. corals, ice cores, and marine sediments.

  Gerrit Lohmann studied physics and mathematics at the Universities Göttingen and Marburg, and received the diploma in physics in 1992. From 1992 to 1995 he worked as a graduate research assistent at the Alfred-Wegener-Institute for Polar and Marine Research in Bremerhaven, Germany. In 1994, he was a visiting scientist at the Earth Science Centre, University of Gothenburg and got a scholarship of the German Academic Exchange Service DAAD. He obtained his Ph.D. Degree in physics in Bremen in 1995. After about 5 years at the Max-Planck-Institute in Hamburg working on climate modelling, he worked at the Geosciences Department of Bremen and the Meteorological Institute at the University of Hamburg. From 2002 to 2004, he had a tenure position at Bremen University, Center for Marine Environmental Sciences and was lecturer at the University of Hamburg and the European Graduate College in Marine Sciences. He authors more than 40 peer-reviewed publications in international journals in the fields of climate modelling, and statistical analysis of observational and proxy data. Since July 2004, he is a professor for "Paleoclimate Dynamics" at the Alfred-Wegener-Institute for Polar and Marine Research in Bremerhaven in cooperation with the Physics Department at the University of Bremen.
