Directory entires that have specified Mackenzie river as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

i. Determine mercury, metals and persistent organic contaminant pollutants (POPs) concentrations in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in 2015 to further extend the long-term (1993-2013 (POPs) and 1993-2014 (mercury)) database. ii. Determine POPs trends in lake trout and burbot using our 1993-2014 data base. iii. Continue our investigations of mercury trends in predatory fish to include lakes in the Deh Cho, Great Bear Lake, and other lakes as opportunities arise. iv. Participate in and contribute information to AMAP expert work groups for trend monitoring for POPs and mercury. v. Integrate our mercury trend assessments with studies we are conducting in the western provinces as part of Canada’s Clear Air Regularly Agenda for its Mercury Science Assessment. vi. Work with communities in capacity building and training.
A proposal has been submitted to the National Science Foundation titled: For Support of the Arctic Social Science Data Center at NSIDC, OPP-0119836.
1. Continue to investigate spatial and temporal patterns in mercury concentrations in fish in lakes in the Mackenzie River Basin with a focus on predatory fish in smaller lakes near Fort Simpson but also including Great Bear Lake 2. Assess temporal trends in mercury concentrations and influencing factors, e.g., climate change 3. Conduct sediment core studies as opportunities allow to characterize long-term trends in mercury deposition and productivity 4. Integrate the findings of this study with our mercury trend monitoring in Great Slave Lake and the western provinces.
