This award is for support of a two year proof-of-concept project to deploy a newly designed and tested instrument which will allow quantitative measurements (with high temporal resolution) of snow accumulation, mixing and erosion. The instrument disperses inert time markers in the snow surface at fixed time intervals which allows a quantitative measure of snow accumulation rate and its spatial uniformity. This work has important applications to the interpretation of paleoclimatic records from snow pits and ice cores.

该奖项是为了支持一个为期两年的概念验证项目， 部署一个新设计和测试的仪器， 雪的定量测量（具有高时间分辨率） 堆积、混合和侵蚀。 该仪器将惰性气体 在固定的时间间隔在雪表面的时间标记， 可以定量测量积雪的累积速度及其 空间均匀性 这项工作有重要的应用， 从雪坑和冰中解释古气候记录 丹
