Funds are awarded to this Post-doctoral Fellow to explore the reasons behind the observed inconsistency between the nutrient retention hypothesis and observations of nitrogen budgets in high latitude catchments areas. She hypothesizes that this may be due to spatial and temporal inhomogeneities in nutrient processing along flowpaths. She will conduct observations of the manner in which permafrost extent influences the sources and forms of nitrogen as well as the relative rates of reaction and transport of nitrogen as a function of permafrost depth. This will be accomplished at a series of scales ? regional, hillslope, and soil profile scales. Observations will be made of both naturally occurring tracers and introduced tracers.

基金授予这位博士后研究员，以探索在高纬度集水区观察到的养分保留假设和氮收支观测之间的不一致背后的原因。 她推测，这可能是由于空间和时间的不均匀性，营养加工沿着流动路径。 她将进行观测的方式，其中永冻范围影响氮的来源和形式，以及反应和氮的运输作为永冻深度的函数的相对速率。 这将在一系列规模上实现？区域、山坡和土壤剖面尺度。 将对天然存在的示踪剂和引入的示踪剂进行观测。
