Research output: Chapter in Book/Conference paperChapter


Irregular sampling is a common problem in palaeoclimate studies. We propose a method that provides regularly sampled time series and at the same time a difference filtering of the data. The differences between successive time instances are derived by a transformation costs procedure. A subsequent recurrence analysis is used to investigate regime transitions. This approach is applied on speleothem-based palaeoclimate proxy data from the Indonesian--Australian monsoon region. We can clearly identify Heinrich events in the palaeoclimate as characteristic changes in dynamics.
