Investigation of paleomagnetic and paleoclimatic data of late Pleistocene with modern methods of nonlinear time series analysis and improving of some of these methods

• Applicant: Professor Dr. Jürgen Kurths
• Subject Area: Geophysics
• Term: from 2000 to 2004
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5249702

The aim of this project is to apply and develop modern techniques of nonlinear data analysis to study complex dynamical relationships between the variations of the Earth's magnetic field and of the climate during the last 100.000 years. We mainly intend to study phase stability and nonlinear correlations of these multivariate data based on new approaches of synchronization analysis and maximal correlations. Problems of special interests are to test for a possible phase delay between climate signals and the relative palaeointensity, to study the influence of long-term variations, especially in the sub-Milankovitch range, and to analyse excursions of relative palaeointensity in detail. The nonlinear analysis of sediment data will be mainly based on the sediment investigations performed in the group of Prof. Negendank and in the group of Prof. Bleil. We will also build up a toolbox of data analysis techniques including modern as well as standard methods; it will be available for other projects in this special research programme.
