| Zusammenfassung |
| Climate variability is triggered by several solar and orbital cycles as well
as by the intern ocean dynamics. Consequently, paleoclimate proxy records are
expected to vary on very different time scales ranging from subdecadal to
millennial duration. We demonstrate, that Foster's (Foster, 1996) wavelet
analysis technique is an appropriate tool for investigating temporarily
changing spectral properties of records characterized by awkward sampling
quality, which is a typical feature of climate proxy records. By applying it
to the Holocene part of different glaciochemical records of Greenland ice
cores we proof evidence for a significant contribution of the 1.47 kiloyears
cycle over alomst the entire Holocene. |
