Our first cyclopod of 2024 is another live episode, where we are joined by Pierre Josso, from the BGS at Keyworth, and Tim van Peer, from the University of Leicester. Tune in to hear about their exploits investigating the origins and implications of Milankovitch cyclicity in the Pb-isotope data from an Atlantic deep-sea iron manganese nodule from offshore West Africa (Josso et al., 2021, EPSL). The Intro music of this podcast is again an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.
