Mid-Brunhes Event

The Mid-Brunhes Event (MBE) is a climatic shift evident in a number of marine sediment and Antarctic ice cores. It corresponds to an increase in amplitude of glacial-interglacial cycles. The Mid-Brunhes Event (MBE) is a climatic shift evident in a number of marine sediment and Antarctic ice cores. It corresponds to an increase in amplitude of glacial-interglacial cycles. The MBE roughly corresponds to the transition between MIS 12 and MIS 11 (Termination V) about 430 kyr ago.
