The Beaufort Regional Environmental Assessment (BREA) is a multi-stakeholder initiative developed to address the needs to understand better potential environmental effects related to exploration drilling in the Beaufort Sea. The Southern and Northeastern Beaufort Sea Marine Observatories were set to support critical goals of the Beaufort Regional Environmental Assessment (BREA). This four-year project led by ArcticNet and IMG-Golder, an Inuit-owned environmental and engineering company based in Inuvik, collected data to gauge the physical conditions and variability of the Canadian Beaufort Sea year over year. More specifically, these data would contribute to ocean circulation model validation, biogeochemical flux and sea-ice information, oil spill trajectory models, and future environmental assessments at the local and regional scales. These observatories were also developed to maintain existing time-series and fill significant data gaps in the northeastern Beaufort Sea. Altogether, the derived information is expected to help researchers to build previously unavailable scientific evidence of oceanic and sea ice conditions, enabling regulators to make informed decisions about potential environmental effects of exploration drilling in the Beaufort Sea. BREA is supported by the Environment Studies Research Fund (ESRF), Imperial Oil Resources Ventures Limited, the Program on Energy Research and Development (PERD), and Fisheries and Oceans Canada (DFO).

Microorganisms are also natures first responders to environmental perturbations, including hydrocarbon-degrading bacteria which can break down oil in this sensitive ecosystem. This is of great interest to the scientific community, policymakers and decision-makers as rapid changes in Arctic ecosystems and accelerating industrial activity pose a greater risk of accidental oil spills. Highlighting the response of the Arctic marine microbiome to oil spills and identifying unique Arctic-specific genes and genomes will guide mitigation efforts in different high-latitude spill scenarios.", "url":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13322", "keywords": [ "Geographic locations -> Arctic", "Geographic locations -> Baffin Bay", "Geographic locations -> Beaufort Sea", "Geographic locations -> Canada", "Geographic locations -> Canadian Arctic Archipelago", "Geographic locations -> Hudson Bay", "Geographic locations -> Hudson Strait", "Geographic locations -> Labrador Sea", "Geographic locations -> Nunatsiavut", "Natural sciences -> Archaea", "Natural sciences -> Bacteria", "Natural sciences -> Marine sediments", "Natural sciences -> Microorganisms" ], "creator":{ "@type":"Person", "name":"Whitney England", "contactPoint":{ "@type":"ContactPoint", "contactType":"technical support", "telephone":"+1-403-461-6522", "email":"whitney.england@ucalgary.ca" } }, "includedInDataCatalog":{ "@type":"DataCatalog", "name":"polardata.ca" }, "temporalCoverage":"2013-Aug-14/2019-Sep-11", "spatialCoverage":{ "@type":"Place", "geo":{ "@type":"GeoShape", "box":"76.383533 -133.638667 53.789833 -54.693817" } }, "license":"https://www.polardata.ca/pdcinput/public/termsofuse" } } ] }
