项目摘要

The BESTCapsule project, Biological and Environmental Specimen Time Capsule project, was proposed by the head investigator in 1989. Since 1994, it has been sponsored by the grant-in-aid for scientific research of the Japanese Ministry of Education (unfil 1998) and the Japan Society for the Promotion of Science (until 2000). The project aims at international networking of long-term cryogenic preservations of biological and environmental specimens for scientific purposes with an ultra-long-term preservation in Antarctica in natural freezing condition as a symbol and a highly-safe back-up system of the artificial preservation projects.The best place on this planet for a natural ultra-long-term preservation selected by the comparative study is the Dome F base of the Japanese mission to Antarctica, on which no ice movement is observed, temperature is very low, i.e., -58 degree C (annual average) due to high elevation of 3,810 m, and annual ice accumulation is only 30 mm thanks to very stable climate condition due to extremely high atmospheric pressure in the middle of ice covered continent.In 1997, scientists from the world working in the cryogenic preservation projects joined in the BESTCapsule workshop held in Osaka, partly supported by this grant. Among them are the seed bank manager of the Millennium seed bank of the Royal Botanic Gardens, Kew of the U.K., which preserves seeds of wild flowers of the world for 500 years, the chief scientists of Environmental Specimen Banks of the U.S.A and Germany, the keeper of the Museum of Mankind of the British Museum, etc. The workshop became a milestone to create an international preservation network through interactive hot discussions.The temperature at the Dome F is too high to preserve most of biological specimens in living condition. Technologies for long-term preservation of these specimens at -60 degree C were also studied.

BESTCapsule项目，生物与环境标本时间胶囊项目，由首席研究员于1989年提出。自1994年以来，它得到了日本文部科学省（至1998年）和日本科学促进会（至2000年）的科学研究资助。该项目旨在建立生物和环境标本长期低温保存的国际网络，以南极自然冷冻条件下的超长期保存为标志，为人工保存项目提供高度安全的后备系统。比较研究选择的地球上最适合自然超长期保存的地点是日本南极考考团的Dome F基地，这里没有冰的运动，由于海拔3810米的高度，温度非常低，年平均温度为-58摄氏度，由于冰层覆盖的大陆中部大气压力非常高，气候条件非常稳定，年积冰只有30毫米。1997年，来自世界各地从事低温保存项目的科学家参加了在大阪举行的BESTCapsule研讨会，部分由该基金支持。其中有保存了500年世界野花种子的英国皇家植物园千年种子库的种子库经理，美国和德国环境标本银行的首席科学家，大英博物馆人类博物馆的管理员等。研讨会通过互动的热议成为创建国际保护网络的里程碑。圆顶F的温度太高，无法保存大多数生物标本。研究了在-60℃下长期保存这些标本的技术。
