Short summary

Evenly spaced carbon and oxygen stable isotope records were produced from central European stalagmites. To mitigate the potential bias of interpolation, the variance spectra were carefully evaluated. The derived data are ready to use with conventional uni- and multivariate statistics, which are usually not prepared to handle the general characteristic of sedimentary paleoclimate records derived from geological sequences unevenly sampled in time.
