Laminated deposition occurred, first under igapo (black-water), and then under varzea (white-water) conditions. The transition occurred ca. 3000 yr BP, a time of major change in El Niño/Southern Oscillation (ENSO) behavior in the Cariaco Basin, thus reflecting the southern migration of the intertropical convergence zone and intensified rain upstream the Cauca Valley. A second, but less conspicuous change occurred ca. 2000 yr BP, which apparently corresponds to the intensified and/or more frequent ENSO activity in the Galapagos Islands. Our contribution describes, for the first time, a ria lake sedimentary succession from the northern Andes and demonstrates the high potential of these hitherto undervalued deposits for the reconstruction of the paleohydrological history of the northern Andes. © 2012 Springer Science+Business Media Dordrecht.enghttps://v2.sherpa.ac.uk/id/publication/issn/0921-2728info:eu-repo/semantics/articleaccumulation ratedepositionEl Nino-Southern OscillationHoloceneintertropical convergence zonelaminationNeotropical RegionpaleohydrologypaleolimnologyreconstructionriaAndesCaucaColombia2021-03-23Ignacio Martinez, J.Mayr, ChristophYokoyama, YusukeVelez, Maria I.Battarbee, Richard W.10.1007/s10933-012-9676-4
