Alaska Water Isotopes Network

The hydrological cycle is central to the structure and function of northern landscapes and is also the basis for interactions between terrestrial, aquatic, marine and atmospheric systems. Understanding the processes and the spatial patterns that govern the stable isotopic characteristics of the hydrological cycle is highly valuable to many fields of fundamental and applied research. Our principle aim is to develop a GIS-based data layer package that will allow us to quantify, analyze, compare and contrast the patterns of stable isotopes in the hydrological cycle across Alaska. We anticipate using this information to understand modern and historical processes including reanalysis of past AK climates using proxies such as tree rings, ice cores, and lake sediments. Understanding modern, historical and ancient processes will provide the basis for forecasting future hydrological and ecological processes.
