Marine Isotope Stage 11
Marine Isotope Stage 11 or MIS 11 is a Marine Isotope Stage in the geologic temperature record, covering the interglacial period between 424,000 and 374,000 years ago. It corresponds to the geological Hoxnian Stage.
Interglacial periods which occurred during the Pleistocene are investigated to better understand present and future climate. Thus, the present interglacial, the Holocene, is compared with MIS 11 or Marine Isotope Stage 5.
== Characteristics ==
MIS 11 represents the longest and warmest interglacial interval of the last 500 kyr. In fact, it shows the highest-amplitude deglacial warming in the last 5 Myr and possibly lasted twice the other interglacial stages. MIS 11 is characterized by overall warm sea-surface temperatures in high latitudes, strong thermohaline circulation, unusual blooms of calcareous plankton in high latitudes, higher sea level than the present, coral reef expansion resulting in enlarged accumulation of neritic carbonates, and overall poor pelagic carbonate preservation and strong dissolution in certain areas. MIS 11 is considered the warmest interglacial period of the last 500,000 years.
