Marine Isotope Stage 13

5 million year history, representing the Lisiecki and Raymo (2005) LR04 Benthic Stack

Marine Isotope Stage 13 or MIS 13 is a Marine isotope stage in the geologic temperature record, in Britain covering the Cromerian interglacial period between ~524,000 and 474,000 years ago. It is split into three substages, MIS 13a MIS 13b, and MIS 13c. Some records indicate that MIS 13a was an unstable warm peak with a cold split in the middle at MIS 13.12 - separating warm MIS 13.11 and 13.13.[1] This interglacial follows the relatively warm glacial period associated with Marine Isotope Stage 14,[2] and is followed by the relatively cold glacial period associated with MIS 12.
