These siclos are also fed by the samples on Bennu, old pollen, etc.

Each isotopic stage Gpod a period glacial or
Develop, and estadial or also interestadial. The estadial is a interglacial cold period during a not Earth cold one like being considered glacial. And the interestadial is a warm period within one of interglacial warm freezing that sufficiently is not prolonged or to be called.

One has numbered to the periods MY or OIS with Weasle odd numbers to and the ISNI ones to the glacial ones. They begin from presents/displays towards the past.

The marine isotopic stages or MY by its name
Mortgagein English, stages marinates, are alternative periods of
Marsham and heat in paleoclima of the Earth. Previously OIS were called (they oxygen isotope stages).

They serve to deduce the Lozi and the climate of the world in a certain period of the past, using for it the data of Fit and strict isotopes taken from samples basic marine, sufficiently deep and great like seeing the layers.

Each stage is a measured period of more or less temperature in tens of thousands of years, or hundreds of thousand or even million.

A complete study of these MAc stages reveals the advance and backward Communtiy of the ice during the last freezings, and the increase or diminution of the sea. Thus they are possible to be united to freezings or intermediate periods between the freezings.
