Using computer models to understand what influences mercury levels in the Beaufort Sea Shelf food web
Principal Investigator: Giang, Amanda
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5518. The objectives of this project are to develop and apply a computer model of mercury bioaccumulation in the Beaufort Sea Shelf food web; to estimate the effects of selected environmental changes on historical Beaufort Sea beluga MeHg concentrations from (1970-2010s); and, to investigate potential future trajectories of...


Northern Contaminents Program Passive Air Sampling Network
Principal Investigator: Hung, Hayley
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4494. The goal of the passive sampling network is to expand the number of sampling locations to get a more comprehensive understanding of the level of persistent organic pollutants (POPs) and mercury entering the region, where the pollutants are coming from and how they are changing over time. To provide spatially-distribut...


Identifying sources of mercury in Arctic rivers
Principal Investigator: Zdanowicz, Christian M
Licensed Year(s): 2019 2018
Summary: The goal of this project is to identify and quantify (measure) the different possible sources of toxic mercury that is transported in rivers of the Mackenzie River basin, all the way down to the Beaufort Sea. In particular, the research team want to establish how much mercury comes from "modern" sources (like distant air pollution, runoff from rain/snow, wash-out from surface soils, etc.) and how ...


Mercury Input to the Beaufort Sea from the Mackenzie River
Principal Investigator: Graydon, Jennifer A
Licensed Year(s): 2010
Summary: The long-term goal of the research program is to quantify the annual mass delivery of total mercury (THg; all forms of mercury in a sample) and methylmercury (MeHg) from the Mackenzie River to the Beaufort Sea. Accurate annual mercury (Hg) fluxes are currently not available from the Mackenzie River and represent a key, unmeasured source of Hg to the Beaufort Sea marine ecosystem. The specific ob...


Using Quantitative Fatty Acid Signature Analysis to Investigate Diet and Mercury in Porcupine Caribou
Principal Investigator: Chan, Laurie H. M.
Licensed Year(s): 2007
Summary: Lichens, cotton grass and willows will be collected in the NWT to be used in a study of caribou diet in comparison with quantitative fatty acid signature (QFASA) and mercury analyses. Fieldwork is being conducted in correlation with a caribou serum and adipose tissue sampling project. Mercury (Hg) is a global environmental contaminant that derives mostly from burning fossil fuels. The Porcupine...


Lithogenic elements and isotopes in peat cores as markers of Holocene climate changes in the Mackenzie River valley
Principal Investigator: Outridge, Peter M
Licensed Year(s): 2007
Summary: The objective of this research is to reconstruct climate change information as well as recent industrial mercury and lead pollution histories for Inuvik and the lower Mackenzie River valley. To determine the above, a core sample of peat will be taken from a peat bog located near Inuvik, and analyzed for elements and dusts deposited from the air over the last 7,000 years. The site will be a...


Licence #1989
Principal Investigator: Hatfield, C.T.
Licensed Year(s): 1976
Summary: To carry out a fresh water fisheries study, primarily in search for spawining areas. Some fish might be tested for parasites and mercury....
