Constructing a strontium isotope map with broad applications for hydrologic and wildife research

Strontium isotope analysis is one of the leading techniques for investigating biological and hydrologic provenance and animal migration patterns. The approach is most effective when strontium isotope maps, or isoscapes, are available to help interpret the data.

The main finding and product of this study has been the production of an enhanced strontium isoscape for Alaska. This has involved the production of new empirical strontium isotope data and new modeling of the data to produce a new and improved strontium isoscape for Alaska.

A major impact of this study has been its role in facilitating further research applications using the strontium map to model movements of animals across the landscape. This has included modeling the movements of ancient bison (Funk et al. 2021) as well as a mammoth that was reported in a high impact publication and received considerable media coverage (Wooller et al. 2021).
