Step 1 : Introduction to the question "3. From the Inuit hamlet of Tuktoyaktuk, one could coolly look out to our next sea, which was named after an Irish hydrographer, although there has been dispute between the USA and Canada over its borders. Where are we now?"
...1. Chazelle Sea 2. Camembert Sea 3. Beaufort Sea 4. Black Sea Tuktoyaktuk has had a fairly stable population of around 900-1000 between 1999 and 2009. The name is more sensibly referred to as 'Tuk' typically, and near Tuk lies the largest concentration of pingos in the world, and pingos are core mounds of ice with layers of ground on top. The Beaufort Sea is named after Francis Beaufort, who developed the Beaufort scale of wind force. The Mackenzie river empties into the Beaufort Sea through the large Mackenzie Delta, and the sea also has large reserves of fossil fuels beneath it, which have been largely untapped into since the 1980s. The border dispute concerns the area of the sea between Yukon, a Canadian territory, and Alaska, an American state, and is likely important to determine who can extract the fossil fuels located in that area.
