PermHg: A Consolidated Database of Mercury Observations for Permafrost Regions

This dataset is part of the Permafrost Mercury Database (PermHg) initiative, which compiles published and unpublished mercury (Hg) concentration measurements from permafrost-affected environments. This component includes vegetation, soil, lake sediment, and aqueous samples collected across Arctic, boreal, and alpine regions. The dataset is provided for long-term archiving and open reuse through Zenodo.
