Séminaire de Bryan Lougheed (Chercheur, Uppsala University Sweden) intitulé :
Radiocarbon (14C) dating challenges in deep‐sea sediment archives

Date : Jeudi 16/05/2019 10h00

Lieu : salle de conf à la MREN à Wimereux et salle 128 SN5 (visio)

Résumé :
"Radiocarbon (14C) dating has been used in palaeoclimate reconstructions for inferring the age of deep-sea sediments up to 50 thousand years old, usually based on the 14C analysis of foraminifera shells. In this presentation, the basis of the method will be presented, as well as some difficulties that may have been overlooked previously. Finally, some future prospectives for improving the accuracy of 14C dating are presented."
