Here we document the AMO signal in the San Nicolás-1 core of the Cauca paleolake (Santa Fé-Sopetrán Basin) in the northern Andes. Wavelet spectrum analysis of the gray scale of the San Nicolás-1 core provides evidence for a 70 yr AMO periodicity for the 3750 to 350 yr BP time interval, whose pattern is analogous to the one documented for the Cariaco Basin. This supports a possible correlation between enhanced precipitation and ENSO variability with a positive AMO phase during the 2000 to 1500 yr BP interval, and its forcing role on the Cauca ria lake deposits, which led to increased precipitation and to the transition from a igapo (black water) to a varzea (white water) environment ca. 3000 yr BP. © Author(s) 2015.enghttps://v2.sherpa.ac.uk/id/publication/issn/1814-9340info:eu-repo/semantics/articleAtlantic Multidecadal OscillationcorrelationEl Nino-Southern OscillationHolocenelacustrine depositlake dynamicspaleoceanographypaleoclimatepaleolimnologyperiodicityprecipitation (climatology)spectrumwavelet analysisAndesArgentinaAtlantic OceanAtlantic Ocean (South)Buenos Aires [Argentina]Cariaco BasinCaribbean SeaCaucaColombiaSan Nicolas2021-03-23Martínez J.I.Obrochta S.Yokoyama Y.Battarbee R.W.10.5194/cpd-11-2649-2015
