Knowra Beaufort Sea Beaufort Sea The Beaufort Sea is a marginal sea of the Arctic Ocean north of Alaska and Canada’s Yukon and Northwest Territories. Its seasonally ice-covered waters border the Arctic coastal plain and the Canadian Arctic Archipelago.
Arctic sea ice : Sea ice is frozen seawater that forms, grows, and melts in polar oceans. Seasonal ice cover governs navigation, ecosystems, and heat exchange across the Beaufort Sea.
Northwest Passage : The Northwest Passage is a set of sea routes through the Canadian Arctic Archipelago connecting the Atlantic and Pacific oceans. Its western approaches cross the Beaufort Sea, where changing ice conditions affect access.
John Franklin : John Franklin was a British Royal Navy officer and Arctic explorer who led expeditions in the early nineteenth century. His 1826 expedition charted part of the coast later associated with the sea bearing his name.
Canada Basin : The Canada Basin is a deep ocean basin in the Arctic Ocean north of Alaska and Canada. It lies offshore from the Beaufort coast and contains the sea’s deeper northern waters.
Arctic amplification : Arctic amplification is the faster warming of the Arctic compared with the global average. It helps explain the rapid loss of sea ice and changing coastal conditions in the Beaufort region.
Beaufort Gyre : The Beaufort Gyre is a wind-driven ocean circulation in the Canada Basin of the Arctic Ocean. This circulation stores freshwater north of the sea and can release it into wider Arctic circulation.
Inuvialuit Settlement Region : The Inuvialuit Settlement Region is the homeland in Canada’s western Arctic established by the Inuvialuit Final Agreement. Its coastal communities depend on Beaufort Sea lands and waters for food, travel, and culture.
Arctic exploration : Arctic exploration is the history of travel, mapping, and scientific investigation in the Arctic region. European mapping of the Beaufort coast emerged from this broader history of exploration.
Chukchi Sea : The Chukchi Sea is a marginal sea of the Arctic Ocean between Alaska and Russia. It adjoins the Beaufort Sea to the west through the Arctic waters north of Alaska.
Sea ice decline : Sea ice decline is the long-term reduction in the extent, thickness, or duration of ocean ice cover. Reduced ice changes Beaufort Sea habitat, coastal protection, and seasonal access.
