Abstract:
This dataset contains the age model of core MD07-3081. It integrates 21 radiocarbon (14C) dates between 50 and 1230 cm and was previously determined by Martínez Fontaine (2021). Depending on foraminifera availability, either monospecific planktonic foraminifera Globigerina bulloides or mixed planktonic foraminifera (Globigerina bulloides, Globorotalia inflata, Globigerinita glutinata, Neogloboquadrina incompta, Neogloboquadrina pachyderma (left coiling) and Turborotalia quinqueloba) were picked from the fraction >150 μm. The age model was obtained with the Undatable software (Lougheed and Obrochta, 2019).
