A high-resolution late Holocene speleothem record from Kaite Cave, northern Spain: δ18O variability and possible causes

A high-resolution calcite oxygen stable isotopic (δ18O) record, covering the past 4000 years, was obtained from Kaite Cave, northern Spain. The record has a mean δ18O value of -6.25% VPDB and a range of 2%. Spectral analysis of the d18O data shows significant periodicities of 2400–1900, 600, 150, 27...
