Tracking the equatorial front in the eastern equatorial Pacific Ocean by the isotopic and faunal composition of planktonic foraminifera

► This study deals with the micropaleontological location of the equatorial front. ► Abundance ratios of G. cultratal N. dutertrei track the EF latitudinal position. ► Δδ18OG.tumida-G.ruber and Δδ18OG.tumida-P.obliquiloculata are also good proxies. ► Reconstruction of the EF based on single species Δδ18O can be achieved by mapping.
