Anthropogenic contaminants from local, regional, or global sources can contribute to the abundance and distribution of trace metals in sea ice and therefore could significantly affect the distribution of dissolved trace metals in surface waters. Offshore exploration and development products (e.g. drilling muds, produced water or oil) are potential local and regional sources, while atmospheric emissions from industrialized regions captured in winter snow are potential regional and global sources. Results from this project will improve understanding of trace metal distribution and abundance in the Arctic sea ice environment, and on its role as a source of trace metals in the water column. BOEM analysts and decision makers will use this information in NEPA analysis and documentation for Lease Sales, EPs and DPPs.
