The Gulf of Cadiz, west of the Strait of Gibraltar, is the site of water exchange between the Atlantic Ocean and the Mediterranean where many palaeoceanographic studies have taken place over the last several decades. Based on 21 cores from three cruises, oxygen isotope curves, 139 radiocarbon dates, and microfaunal analyses, this work presents and discusses the main bioevents used as detailed biostratigraphic points in this area for the late Quaternary. Those bioevents, such as well-known cold events (Younger Dryas, Heinrich events) or bioevents occurring during the Holocene, are essentially based on planktonic foraminifer species and/or coiling ratio and the point occurrences of pteropod species. The large and extensive data set allows us to discuss ages and the spatial validity of such bioevents.< Réduire
