The Strait of Juan de Fuca is a body of water about 96 miles long that is the Salish Sea's main outlet to the Pacific Ocean. The international boundary between Canada and the United States runs down the centre of the Strait.
The 49th parallel north is a circle of latitude that is 49° north of Earth's equator. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
The Beaufort Sea is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, Yukon, and Alaska, and west of the Canadian Arctic Archipelago. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores.
The Canada–United States border is the longest international border in the world. The boundary is 8,891 km (5,525 mi) long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP).
Machias Seal Island is an island in disputed water between the Gulf of Maine and the Bay of Fundy, about 16 km (10 mi) southeast from Cutler, Maine, and 19 km (12 mi) southwest of Grand Manan Island, New Brunswick. Sovereignty of the island is disputed by the United States and Canada. The Canadian Coast Guard continues to staff a lighthouse on the island; the first lighthouse was constructed there in 1832.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.
The Dixon Entrance is a strait about 80 kilometers (50 mi) long and wide in the Pacific Ocean at the Canada–United States border, between the U.S. state of Alaska and the province of British Columbia in Canada. The Dixon Entrance is part of the Inside Passage shipping route. It forms part of the maritime boundary between the U.S. and Canada, although the location of that boundary here is disputed.
Dall Island is an island in the Alexander Archipelago off the southeast coast of Alaska, just west of Prince of Wales Island and north of Canadian waters. Its peak elevation is 2,443 feet above sea level. Its land area is 254.0 square miles (657.9 km2), making it the 28th largest island in the United States. Dall is used economically for fishing and limestone quarrying.
Border irregularities of the United States, particularly panhandles and highway incursions into other jurisdictions, are shown here. Often they are a result of borders which do not conform to geological features such as changes in the course of a river that previously marked a border.
The Treaty of Saint Petersburg of 1825 or the Anglo-Russian Convention of 1825, officially the Convention Concerning the Limits of Their Respective Possessions on the Northwest Coast of America and the Navigation of the Pacific Ocean, defined the boundaries between Russian America and British claims and possessions of the Pacific Coast, and the later Yukon and Arctic regions of North America. It was agreed that along the coast at the southern tip of Prince of Wales island northward to the 56 parallel, with the island wholly belonging to Russia, then to 10 marine leagues (56 km) inland going north and west to the 141st meridian west and then north to the "Frozen Ocean", the current Alaska/Canadian Yukon boundary, would be the boundary. The coastal limit had, the year before, been established as the limit of overlapping American claims in the parallel Russo-American Treaty of 1824. The Russian sphere in the region was later sold to the United States, eventually becoming the State of Alaska, while the British claim, along the coast to the south of parallel 54°40′ is now the coast of the Canadian province of British Columbia, and for inland regions it defined the western limit of what became the modern day Canadian territory of Yukon. It also defined associated rights and obligations concerning waters and ports in the region. The treaty, in establishing a vague division of coastal Russian interests and inland British interests between 56 and 60 degrees north latitude, led to conflicting interpretations of the meaning of the treaty's wording which later manifested in the Alaska Boundary Dispute between the United States on the one hand, and Canada on the other.
The United States has land borders with only Canada and Mexico, both of them long. It has maritime boundaries with many countries due to its extensive exclusive economic zone (EEZ). All of its maritime borders with Canada are at least partially disputed, and its territorial claims on three Caribbean islands are disputed.
The Arctic consists of land, internal waters, territorial seas, exclusive economic zones (EEZs) and international waters above the Arctic Circle. All land, internal waters, territorial seas and EEZs in the Arctic are under the jurisdiction of one of the eight Arctic coastal states: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. International law regulates this area as with other portions of Earth.
The Coastal Waters of Southeast Alaska and British Columbia is a marine area designated by the International Hydrographic Organization (IHO).
The Canada–France Maritime Boundary Case was a dispute between Canada and France that was decided in 1992 by an arbitral tribunal created by the parties to resolve the dispute. The decision established the extent of the Exclusive Economic Zone of the French territory of Saint Pierre and Miquelon.
Australia's exclusive economic zone (EEZ) was declared on 1 August 1994 and extends from 12 to 200 nautical miles from the coastline of Australia and its external territories, except where a maritime delimitation agreement exists with another state. To the 12 nautical-mile boundary is Australia's territorial waters. Australia has the third-largest exclusive economic zone, behind France and the United States but ahead of Russia, with the total area of 8,148,250 square kilometres (3,146,060 sq mi), which exceeds its land territory.
Vietnam claims an exclusive economic zone (EEZ) of 1,395,096 km2 (538,650 sq mi) with 200 nautical miles from its shores.
Thailand has the world's 64th largest exclusive economic zone (EEZ), with an area of 299,397 km2 (115,598 sq mi). It claims an EEZ of 200 nmi from its shores, which has long coastlines with the Andaman Sea and Strait of Malacca to the west and the Gulf of Thailand to the east, although all of its EEZ is limited by maritime boundaries with neighbouring countries.
The United Kingdom's exclusive economic zone is the fifth largest in the world at 6,805,586 km2 (2,627,651 sq mi). It comprises the exclusive economic zones surrounding the United Kingdom, the Crown Dependencies, and the British Overseas Territories. The figure does not include the EEZ of the British Antarctic Territory.
The United States has the world's second-largest exclusive economic zone (EEZ). The total size is 11,351,000 km2 (4,383,000 sq mi)2. Areas of its EEZ are located in three oceans, the Gulf of Mexico, and the Caribbean Sea. Most notable areas are Alaska, Hawaii, the East Coast, West Coast and Gulf Coast of the United States.
Italy has the world's 48th largest exclusive economic zone (EEZ), with an area of 541,915 km2 (209,235 sq mi). It claims an EEZ of 200 nmi from its shores, which has long coastlines with the Tyrrhenian Sea to the west, the Ionian Sea to the south and the Adriatic Sea to the east. Its EEZ is limited by maritime boundaries with neighboring countries to the north-west, east and southeast.
