This Small Grant for Exploratory Research (SGER) supports the research to assess the feasibility of recovering ancient microorganisms entrapped in deep glacial ice cores. A major goal will be to establish the reliability of obtaining ancient organisms for comparative studies with contemporary ogranisms. The reseach will establish valid techniques for the recovery of microorganisms from ice cores stored at the Ice Core Storage Facility in Buffalo, N.Y., and then attempt in recover viable, ancient organisms from ice cores drilled in Greenland and Antarctica. By studying successively older strata in ice cores, the longevity of different taxa entrapped in ice can be estimated. Organisms that are successfully recovered can also be used as model organisms for research on rates of biological evolution, mechanisms of dormancy, their ecological relevance and processes of natural preservation.

探索性研究小额赠款（SGER）支持 研究评估恢复古代 微生物被困在深冰川冰芯中。 一个主要目标 将是建立获取古代 与当代有机体进行比较研究。 该研究将为回收 来自冰芯储存处储存的冰芯的微生物 位于纽约州布法罗的工厂，然后尝试恢复可行性， 从格陵兰钻取的冰芯中提取的古代生物， 南极洲 通过研究冰芯中的更古老的地层， 不同种类的冰中生物的寿命 估算 成功回收的生物体也可以 用作研究生物学速率的模式生物 进化，休眠机制，它们的生态相关性， 自然保护的过程。
