 Marine Isotope Stage 13

Marine Isotope Stage 13 (MIS 13) is a specific period in Earth's geological history that occurred during the Pleistocene epoch. It is part of a series of glacial and interglacial periods that are characterized by changes in Earth's climate and ice volume over time, as recorded in deep-sea sediment cores and ice cores. MIS 13 is generally dated to around 480,000 to 450,000 years ago.
