The Norwegian Sea record of the last interglacial to glacial transition
International audience A detailed analysis of the δ$^{18O}$ record of benthic foraminifera in deep sea cores from the Norwegian Sea shows that at the end of the Eemian interglacial (isotopic substage 5e), continental ice sheets experienced a significant phase of growth, which culminated during the m...
