(2017) Total and methylated mercury in Canadian Arctic waters (2016). Waterloo, Canada: Canadian Cryospheric Information Network (CCIN). Unpublished Data Unfiltered aqueous total and methyl mercury concentrations were measured from water collection on board the NGCC/CCGS Amundsen at stations within the Beaufort Sea, Amundsen Gulf, and the Canadian Arctic Archipelago. Profiles of 10-12 m depth resolution were collected from 15 stations using the ship rosette system. Total mercury samples were analyzed on board. Methylmercury samples were preserved and transported to Winnipeg for analysis. Interpretation of results will also rely on supporting data from ArcticNet collaborators to identify water masses and determine biological productivity that determine the relative importance of external sources and internal cycling. The bioaccumulation of mercury in marine food webs poses potential health risks to consumers. The shallow Arctic Ocean receives seawater inputs from the Atlantic and Pacific Oceans as well as substantial freshwater input from rivers, all of which can transport mercury to Arctic waters. The fate of mercury that enters Arctic waters, including its susceptibility for uptake into the Arctic food web, depends on its chemical speciation, which is subject to transformation due to water column and sedimentary processes. Transects of river systems were targeted in order to determine the relative importance of mercury sources and the potential for methyl mercury production in Arctic systems.
