aliases of Marine isotope stages:
- MIS
- marine oxygen-isotope stages
- oxygen isotope stages (OIS)
MIS are alternating warm and cold periods in the earth history. They study the oxygen isotope data from deep sea core samples to know the changes in temperature long ago.
Stages with even numbers have lower O^18^ levels and represent cold glacial periods.
Stages with odd numbers have higher O^18^ levels and represent warm interglacial periods.
Holocene is the current geological epoch, beginning about 11,650 Cal years before present. Holocene and preceding Pleistocene form the Quaternary period together.
