Like a prehistoric fly trapped in amber during dinosaurs' days, airborne relics of Earth's earlier climate—including dust, air bubbles, sea salts, volcanic ash, and soot from forest fires—can end up trapped in glacial ice for eons. To climate scientists, those relics tell a story about how our planet's climate and atmosphere have changed over thousands of years. The embedded pebbles and dingy ice tell researchers that this portion of the ice core is from the bottom of the glacier, right above bedrock.
An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier.
Preceding the time when the drilling of deep ice cores took place, fossil finds from ice-free areas supplied components to describe past warm climatic periods. The DNA molecules are degraded and fragmented with temporarily since the time of incorporation to the soil of the past ecosystems. The DNA be handys from the organisms that moment lived in the area that is today ice covered.
Beside sensitive DNA techniques the preserved DNA molecules can be analyzed and provide new data revealing about past climate periods fitting prior to ice coverage.
These warm period ecosystems are compelling as it gives researchers the opportunity to compare current atmosphere change with changes that occurred more than , years ago.
From the moment an body dies, its DNA decays and fragments. In frozen conditions the decomposition process goes slowly, while DNA-decomposing enzymes and chemical processes work much faster in conditions. If the DNA is bound to soil particles in dry or cold ice, or permafrost, the decomposing effect of enzymes will be lessened considering the charges of the disgrace particles may have a stabilizing and protectingeffect on the DNA.
