  abstract = {{I}n this paper we explore a speleothem delta {O}-18 record from {P}alestina cave, northwestern {P}eru, at a site on the eastern side of the {A}ndes cordillera, in the upper {A}mazon {B}asin. {T}he delta {O}-18 record is interpreted as a proxy for {S}outh {A}merican {S}ummer {M}onsoon ({SASM}) intensity and allows the reconstruction of its variability during the last 1600 years. {T}wo periods of anomalous changes in the climate mean state corresponding to the {M}edieval {C}limate {A}nomaly ({MCA}) and the {L}ittle {I}ce {A}ge ({LIA}) periods identified in the {N}orthern {H}emisphere are recognized in the record, in which decreased and increased {SASM} activity, respectively, have been documented. {V}ariations in {SASM} activity between the {MCA} and the {LIA} seem to be larger over the northern part of the continent, suggesting a latitudinal dependence of the {MCA} footprint. {O}ur results, based on time series, composite and wavelet analyses, suggest that the {A}tlantic {M}ultidecadal {O}scillation ({AMO}) plays an relevant role for {SASM} modulation on multidecadal scales (similar to 65 years), especially during dry periods such as the {MCA}. {C}omposite analyses, applied to evaluate the influence of the {AMO} on the {P}alestina cave delta {O}-18 and other delta {O}-18-derived {SASM} reconstructions, allow insight into the spatial footprints of the {AMO} over tropical {S}outh {A}merica and highlight differences between records during key studied periods. {T}his work also reveals that replicating regional climate signals from different sites, and using different proxies is absolutely essential for a comprehensive understanding of past changes in {SASM} activity.},
