AB Quantitative correlation with planktic foraminifera at Alamedilla (Betics), Zumaya (Pyrenees) and Site 401 (Bay of Biscay) allows us to infer paleoceanographical trends during Paleocene-Eocene transition in a subtropical to cool environment transect. Similar faunal events are observed in the three sections, which suggest also similar paleoclimatic changes at different latitudes in surface waters. The benthic foraminifera/ extinction event at the P/E boundary coincides with a change in the warm/cool planktic foraminifera species ratio that indicates a surface water warming, accompanied by an increase in the acarininid population. After this warming pulse> a short-term cooling can be inferred by the change in the warm/cool ratio. This is the first study that using planktic foraminifera points out this post-P/E short term cooling in the general warming trans-P/E trend
