Concentrations of alternative flame retardants and polybrominated diphenyl ethers (PBDEs) were analyzed in ringed seal (Phoca hispida) blubber collected across the Canadian Arctic during subsistence hunts between 1998 and 2013. The presence of flame retardants in ringed seals suggests their persistence and their continuous inputs in the Canadian Arctic environment. Monitoring and research on the effects of these contaminants in seals are warranted given the importance of this species in Arctic marine food webs and for local communities.

The Northern Contaminants Program (NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DBA.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples.

The accompanying dataset contains all transactions catalogued in the Sealed Source Tracking System for the 2017 calendar year. The SSTS is used in conjunction with the National Sealed Source Registry to track and report the movement of high- and very high-risk sealed sources within Canada. Sealed sources are radioactive nuclear substances that are encapsulated or bonded to a cover to prevent the loss of radioactive contents. Sealed sources are used in a variety of medical, industrial, commercial and academic and research applications.

Ringed seals (Phoca hispida) have been used as bioindicator species of environmental contamination in Canada since the 1970s. In the present study, seals were harvested during subsistence hunts in four regions of the Canadian Arctic: Beaufort Sea, Arctic Archipelago, Hudson Bay, and coastal Labrador. An extensive suite of persistent organic pollutants (POPs) was determined in seal blubber collected for multiple years between 1972 and 2016. Results from this long-term study indicate geographical differences in the contaminant concentrations in seals and the significant general decrease of most POPs, including polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and related compounds, chlordanes (CHL), and hexachlorocyclohexanes (HCH) over time in ringed seals.

Harbour seals (Phoca vitulina) are found along temperate and Arctic marine coastlines of the Northern Hemisphere. They are found in coastal waters of the northern Atlantic and Pacific Oceans, as well as those of the Baltic and North Seas. In Canada, they may be found off the coastal waters of British Columbia, Nunavut, Manitoba, Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia, and Newfoundland and Labrador. Population trends and abundance of harbour seals in British Columbia are assessed based on aerial surveys conducted during 1966-2014.

Grey Seal presence in the Bay of Fundy and Port Hawkesbury Area Response Plan. The Coastal Oceanography and Ecosystem Research section (DFO Science) reviewed reported opportunistic sightings and local knowledge sources to estimate areas where Grey Seals are present and delineated these areas.

A version of this dataset was created for the National Environmental Emergency Center (NEEC) following their data model and is available for download in the Resources section.

Known Harbour seal presence in the Bay of Fundy and Port Hawkesbury areas. The Coastal Oceanography and Ecosystem Research section (DFO Science) reviewed science sources and local knowledge sources to estimate where Harbour seals are seasonally present and delineate these areas. As of March 2017, this dataset delineates the presence of Harbour seals in the Bay of Fundy and Port Hawkesbury areas of Nova Scotia designated within the Area Response Planning (ARP), identified under the World Class Tanker Safety System (WCTSS) initiative, based on the Transport Canada Response Organizations Standards.

The accompanying dataset contains information about lost, stolen and found licensable sealed sources and radiation devices since 2008. Licensees have an obligation to report these occurrences. The dataset was generated by the Canadian Nuclear Safety Commission (CNSC) from events reported to the CNSC by licensees and members of the public. The same information is used to produce the Reports on Lost or Stolen Sealed Sources and Radiation Devices that is published on the CNSC’s website.

Ringed seals (Phoca hispida) are harvested annually in Arviat and Resolute (Nunavut), Sachs Harbour (Northwest Territories) and Nain (Labrador) with the help of the communities in the context of an environmental monitoring program. Samples of meat, blubber, liver and kidney are collected for inorganic elements and organic contaminants analyses along with a variety of biological/life history parameters measurements such as age, length, weight, body condition, stable isotopes of nitrogen and carbon, blubber thickness, and lipid content. Data have been collected since 1991, but mostly since 2004, and this project is ongoing. Supplemental Information
