In what the New York Times somewhat hyperbolically calls a "clash," US Border Patrol vessels have over the past two weeks stopped at least 10 Canadian fishing boats in the Bay of Fundy between Maine and New Brunswick. Canada has responded by beefing up its Coast Guard patrols in what is being termed a "disputed gray zone" between the two countries' territories. The maritime dispute dates back to the 1783 Treaty of Paris that ended the American Revolution, and is one of several between the US and Canada—including fishing waters at Dixon Entrance between Alaska and British Columbia, and areas of the petroleum-rich Beaufort Sea, near the Arctic Ocean. (Map: ResearchGate)
