The project is to develop a state-of-the-art liquid nitrogen storage facility for the Museum of Zoology (UMMZ) at the University of Michigan. The two year project involves the acquisition and installation of the liquid nitrogen freezers, inventory and transfer of previously accessioned tissues from old -80 degree C ultralow freezers to new -190 degree C liquid nitrogen freezers, and accession and transfer of a backlog of frozen tissues. The lower temperature offered by the liquid nitrogen freezers coupled with a static holding time of eight days will ensure both higher quality and safer long-term storage of tissues. The UMMZ is an internationally recognized center of biodiversity research and teaching. It houses a Development of a Liquid Nitrogen Storage Facility for Frozen Tissues at the University of large collection of animals and associated materials, including frozen tissue, representing all primary global ecosystems. The collections provide data that inform conservation practices and climate change research. Five of the six Divisions (Fishes, Mollusks, Herpetology, Birds and Mammals) maintain frozen tissue collections totaling over 36,500 specimens. They serve as an important source of genetic material for biodiversity research and are utilized by researchers from all over the world. The proposed accessioning activities associated with this grant will immediately result in increased use of the resource.

该项目将为密歇根大学的动物学博物馆(UMMZ)开发一个最先进的液氮储存设施。这项为期两年的项目涉及购置和安装液氮冷冻机，盘存和转移以前从-80摄氏度的旧超低冰柜到新的-190摄氏度液氮冷冻机的组织，以及加入和转移积压的冷冻组织。液氮冷冻机提供较低的温度，再加上8天的静态保存时间，将确保组织更高质量和更安全的长期储存。UMMZ是国际公认的生物多样性研究和教学中心。该中心设有一个冷冻组织液氮储存设施开发中心，该中心收集了代表全球所有主要生态系统的大量动物和相关材料，包括冷冻组织。这些收集提供了为保护实践和气候变化研究提供信息的数据。六个部门中的五个(鱼类、软体动物、爬行动物、鸟类和哺乳动物)保存着总计超过36,500个标本的冷冻组织收集。它们是生物多样性研究的重要遗传物质来源，被世界各地的研究人员利用。与这笔赠款相关的拟议加入活动将立即导致资源使用量的增加。
