Quantifying groundwater and aufeis and their contribution to surface water availability and habitat in the Arctic National Wildlife Refuge, Alaska

This project aims to partition water sources to rivers in the 1002 region of the Arctic National Wildlife Refuge in order to more accurately quantify water resources


Groundwater is a critical source of liquid water in the Arctic National Wildlife Refuge, creating habitat that supports fish and wildlife. Despite the importance of groundwater, little is known about the source and age of groundwater, or spatial and temporal variability in its contribution to rivers, lakes, and associated habitat. Understanding the physical controls on groundwater flow and the links between groundwater, rivers, and habitat is necessary in order properly manage this limited resource.
