This award supports a project designed to confirm that the East Antarctic ice sheet has become thinner in the past 100,000 years. The project will measure the exposure ages and erosion rates of Antarctic rocks from Southern Victoria Land using in-situ produced Beryllium-10 and Aluminum-26, in collaboration with Drs. Gunter Faure and Teresa Mensing at the Ohio State University. This new surface exposure dating method is applicable to various geomorphological subjects and is especially useful in Antarctica. Measurement of other in-situ produced cosmogenic nuclides, particularly 14C and 21Ne, will be performed for selected samples.

该奖项支持一个旨在确认南极东部冰盖在过去10万年里变薄的项目。该项目将与俄亥俄州立大学的Gunter Faure博士和Teresa Mensing博士合作，使用原位生产的铍-10和铝-26来测量南维多利亚陆地上南极岩石的暴露年龄和侵蚀速率。这种新的地表暴露测年方法适用于各种地貌学科，尤其适用于南极地区。将对选定的样品进行其他就地生产的宇宙成因核素的测量，特别是14C和21Ne。
