This study aimed to provide insights into how climate-driven diet shifts may impact contaminant exposures of Arctic species. We compared feeding ecology and contaminant concentrations in ringed seals (Pusa hispida) from two Canadian sub-Arctic (Nain and Arviat) and two Arctic sites (Sachs Harbour and Resolute Bay). All data are a part subject of a publication containing method details, full QA/QC, interpretation and conclusions: Facciola, N., Houde, M., Muir, D. C. G., Ferguson, S. H., & McKinney, M. A. (2022). Feeding and contaminant patterns of sub-arctic and arctic ringed seals: Potential insight into climate change-contaminant interactions. Environmental pollution (Barking, Essex : 1987), 313, 120108. doi.org/10.1016/j.envpol.2022.120108 Supplemental Information The Northern Contaminants Program (NCP, https://science.gc.ca/site/science/en/northern-contaminants-program) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples. Early studies found a wide variety of substances, many of which had no Arctic or Canadian sources, but which…
