The method of recurrence plots is extended to the cross recurrence plots
(CRP), which among others enables the study of synchronization or time
differences in two time series. This is emphasized in a distorted main diagonal
in the cross recurrence plot, the line of synchronization (LOS). A
non-parametrical fit of this LOS can be used to rescale the time axis of the
two data series (whereby one of it is e.g. compressed or stretched) so that
they are synchronized. An application of this method to geophysical sediment
core data illustrates its suitability for real data. The rock magnetic data of
two different sediment cores from the Makarov Basin can be adjusted to each
other by using this method, so that they are comparable.Comment: Nonlinear Processes in Geophysics, 9, 2002, in pres
