Termination, as used by Quaternary geologists, oceanographers, and paleoclimatologists is the period of time during a glacial cycle when there is a relatively rapid transition from full glacial climates to full interglacial climates. For the Quaternary period, terminations are numbered using Roman numerals from the most recent termination as “I” and with increasing value, e.g. “II”, “III”, and so forth, into the past. Termination I, also known as the Last Glacial Termination, is the end of Marine isotope stage 2; Termination II is the end of Marine Isotope Stage 6; Termination III is the end of Marine Isotope Stage 8; Termination IV is the end of Marine Isotope Stage 10, and so forth.
