Wavelet analysis of Late Holocene stalagmite records from Ortigosa Caves in Northern Spain
Abstract:
We have deduced short-term climatic changes from millennial to annual scales from the study of laminae thickness and radiocarbon analysis of Holocene stalagmite records from two caves in Ortigosa de Cameros (Iberian Range, northern Spain). Speleothems are made up of dark compact laminae (DCL) and white porous laminae (WPL) of seasonal origin. Couplets seasonality is deduced from monitoring calcite laminae growth, drip water rates, and soil organic matter flushed into the caves. The thickness variations of the couplets are analyzed using a continuous wavelet transform and the various periodicities at interannual, decadal, multidecadal, and centennial scales are revealed from the wavelet power spectrum. The periodicities at decadal, multidecadal and centennial scales, with periods around 9.7, 10.4, 14, 16, 22, 43, 73, 83 and 180 years, are mainly related to solar activity. Among the interannual periodicities, oscillations around the 2.4-yr-period may be linked to the Quasi-Biennial Oscillation (QBO), whereas periods ranging from 4 to 7 years may be associated with the El Nin o-Southern Oscillation (ENSO) and/or the North Atlantic Oscillation (NAO).
