Ice sheet modeling is used to date ice cores and study long-term interaction between climate and the dynamics of large ice sheets. Information gained from studies of ice texture and fabric, ice rheology, and ice densification is crucial to this objective. Models predict that the ice sheet over Vostok will thin during cold periods. In agreement, the long-term trends of total air content in the ice show that during colder periods air pressure was higher. This supports the idea that elevation of the ice sheet was lower.
G are nearly complete and exciting results have emerged.
The warmest part of this penultimate interglacial was likely as warm as today in Antarctica. One of the most remarkable result derived from this new record is the striking similarity of the last two climatic cycles, which is not documented in any other paleorecord. An isotope that can be used to study the age and origin of the Earth. Forams A family of aquatic microorganisms that are important as age indicators, as rock-building agents, and in seafloor deposits. The separation of chemical elements in nature.
