Changing climate in northern regions is causing permafrost to thaw with major implications for the cycling of mercury in arctic and subarctic ecosystems. Permafrost occurs in nearly one quarter of the Earth’s northern land mass and an estimated 13 percent of Earth’s entire land surface. Large-scale thaw will release Hg currently frozen in permafrost, impacting aquatic resources and posing a serious threat to human health. We measured sediment total Hg concentration in 548 samples from 13 permafrost cores from the interior and the North Slope of Alaska. This published datset supports our data set and tresulting publication. This data is available to stakeholders and resource managers to aid in policy-making decisions in regard to mercury contamination in the environment
