While hydrocarbon exploration and extraction in the Arctic ebbs and flows, reduced sea ice has opened new travel routes across the Arctic. The opening of the Northwest Passage has allowed larger ships (including oil tankers) and higher traffic into remote regions. More ice loss is expected in the future. With this comes the potential for hydrocarbon spills. To quantify the ecosystem impacts of a spill in the Alaska North Slope region, an Ecospace model using the Ecopath with Ecosim software was developed. We highlight the impacts of four potential hydrocarbon contamination scenarios: a subsurface crude oil pipeline release, a surface …

The Beaufort Sea coastal-marine ecosystem is a 476,000 km2 area in the Arctic Ocean, which extends from -112.5 to -158.0° longitude to 67.5 to 75.0° latitude. Within this polar area the United States indigenous communities of Barrow, Kaktovik, and Nuiqsut, and the Canadian indigenous communities of Aklavik, Inuvik, Tuktoyaktuk, Paulatuk, Ulukhaktok, and Sachs Harbour, subsist by harvesting marine mammals, fish, and invertebrates to provide the majority of their community foods. The Beaufort Sea coastal-marine ecosystem includes many specialized marine animals whose life history is tied to the sea ice, such as polar bears that rely on sea-ice for foraging activities …
