Northwest Atlantic Marine
The Northwest Atlantic Marine Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian marine ecozone forming a transitional region between the cold northern waters of the Arctic Ocean and the more temperate waters in its southern extent. Geography Stretching in a narrow strip offshore from Ellesmere Island and Devon Island in Baffin Bay, it runs parallel to the coast of Bylot Island and Baffin Island until meeting it at the Cumberland Peninsula. It covers the waters of the Davis Strait and the Hudson Strait, Ungava Bay and portions of the Labrador Sea, including all coastal areas of Labrador and the northern coast of Newfoundland. It also includes the Gulf of Saint Lawrence to the mouth of the Saint Lawrence River. The cold, highly saline North Atlantic Deep Water forms in the Labrador Sea and flows at great depth along the western edge of the North Atlantic. Moreover, in this ecozone the cold Labrador Current meets the Gulf Stream at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narwhal
The narwhal, also known as a narwhale (''Monodon monoceros''), is a medium-sized toothed whale that possesses a large "tusk" from a protruding canine tooth. It lives year-round in the Arctic waters around Greenland, Canada and Russia. It is one of two living species of whale in the family Monodontidae, along with the beluga whale, and the only species in the genus ''Monodon''. The narwhal males are distinguished by a long, straight, helical tusk, which is an elongated upper left canine. The narwhal was one of many species described by Carl Linnaeus in his publication ''Systema Naturae'' in 1758. Like the beluga, narwhals are medium-sized whales. For both sexes, excluding the male's tusk, the total body size can range from ; the males are slightly larger than the females. The average weight of an adult narwhal is . At around 11 to 13 years old, the males become sexually mature; females become sexually mature at about 5 to 8 years old. Narwhals do not have a dorsal fin and thei ...

Baffin Bay
Baffin Bay ( Inuktitut: ''Saknirutiak Imanga''; kl, Avannaata Imaa; french: Baie de Baffin), located between Baffin Island and the west coast of Greenland, is defined by the International Hydrographic Organization as a marginal sea of the Arctic Ocean. It is sometimes considered a sea of the North Atlantic Ocean. It is connected to the Atlantic via Davis Strait and the Labrador Sea. The narrower Nares Strait connects Baffin Bay with the Arctic Ocean. The bay is not navigable most of the year because of the ice cover and high density of floating ice and icebergs in the open areas. However, a polynya of about , known as the North Water, opens in summer on the north near Smith Sound. Most of the aquatic life of the bay is concentrated near that region. Extent The International Hydrographic Organization defines the limits of Baffin Bay as follows: History The area of the bay has been inhabited since BC. Around AD 1200, the initial Dorset settlers were replaced by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Stream
The Gulf Stream, together with its northern extension the North Atlantic Current, North Atlantic Drift, is a warm and swift Atlantic Ocean, Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States then veers east near 36 latitude (North Carolina) and moves toward Northwest Europe as the North Atlantic Current. The process of Boundary current, western intensification causes the Gulf Stream to be a northwards accelerating current off the east coast of North America. At about , it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current, recirculating off West Africa. The Gulf Stream influences the climate of the coastal areas of the east coast of the United States from Florida to southeast Virginia (near 36 north latitude), and to a greater degree the climate of Northwest Europe. There is consensus that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Atlantic Deep Water
North Atlantic Deep Water (NADW) is a deep water mass formed in the North Atlantic Ocean. Thermohaline circulation (properly described as meridional overturning circulation) of the world's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic. Water flowing northward becomes modified through evaporation and mixing with other water masses, leading to increased salinity. When this water reaches the North Atlantic it cools and sinks through convection, due to its decreased temperature and increased salinity resulting in increased density. NADW is the outflow of this thick deep layer, which can be detected by its high salinity, high oxygen content, nutrient minima, high 14C/12C, and chlorofluorocarbons (CFCs). CFCs are anthropogenic substances that enter the surface of the ocean from gas exchange with the atmosphere. This distinct composition allows its path to be traced as it mixes with Circumpolar Deep Water (CDW), which in turn fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Lawrence River
The St. Lawrence River (french: Fleuve Saint-Laurent, ) is a large river in the middle latitudes of North America. Its headwaters begin flowing from Lake Ontario in a (roughly) northeasterly direction, into the Gulf of St. Lawrence, connecting the American Great Lakes to the North Atlantic Ocean, and forming the primary drainage outflow of the Great Lakes Basin. The river traverses the Canadian provinces of Ontario and Quebec, as well as the U.S. state of New York, and demarcates part of the international boundary between Canada and the United States. It also provides the foundation for the commercial St. Lawrence Seaway. Names Originally known by a variety of names by local First Nations, the St. Lawrence became known in French as ''le fleuve Saint-Laurent'' (also spelled ''St-Laurent'') in 1604 by Samuel de Champlain. Opting for the ''grande riviere de sainct Laurens'' and ''fleuve sainct Laurens'' in his writings and on his maps, de Champlain supplanted previous Fre ...

Newfoundland (island)
Newfoundland (, ; french: link=no, Terre-Neuve, ; ) is a large island off the east coast of the North American mainland and the most populous part of the Canadian province of Newfoundland and Labrador. It has 29 percent of the province's land area. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon. With an area of , Newfoundland is the world's 16th-largest island, Canada's fourth-largest island, and the largest Canadian island outside the North. The provincial capital, St. John's, is located on the southeastern coast of the island; Cape Spear, just south of the capital, is the easternmost point of North America, excluding Greenland. It is common to consider all directly neighbouring i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labrador Sea
The Labrador Sea (French: ''mer du Labrador'', Danish: ''Labradorhavet'') is an arm of the North Atlantic Ocean between the Labrador Peninsula and Greenland. The sea is flanked by continental shelf, continental shelves to the southwest, northwest, and northeast. It connects to the north with Baffin Bay through the Davis Strait. It is a marginal sea of the Atlantic. The sea formed upon separation of the North American Plate and Greenland Plate that started about 60 million years ago and stopped about 40 million years ago. It contains one of the world's largest turbidity current channel systems, the Northwest Atlantic Mid-Ocean Channel (NAMOC), that runs for thousands of kilometers along the sea bottom toward the Atlantic Ocean. The Labrador Sea is a major source of the North Atlantic Deep Water, a cold water mass that flows at great depth along the western edge of the North Atlantic, spreading out to form the largest identifiable water mass in the World Ocean.

Ungava Bay
Ungava Bay (french: baie d'Ungava, ; iu, ᐅᖓᕙ ᑲᖏᖅᓗᒃ/) is a bay in northeastern Canada separating Nunavik (far northern Quebec) from Baffin Island. Although not geographically apparent, it is considered to be a marginal sea of the Arctic Ocean for climatic reasons. The bay is roughly oval-shaped, about at its widest point and about in length; it has an area of approximately . It is generally fairly shallow, under , though at its border with the Atlantic Ocean depths of almost are reached. Geography Although it is quite close to the open Atlantic (separated only by Hudson Strait), Ungava Bay is part of the Arctic Ocean. Ungava Bay is separated from Hudson Bay by the Ungava Peninsula. Akpatok Island is largest of the many islands in Ungava Bay. Bathymetric studies suggest that Ungava Bay may be the remnant of an impact crater (age unknown) approximately in diameter. The southwestern corner of Ungava Bay vies with the Bay of Fundy for the highest tidal range in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hudson Strait
Hudson Strait (french: Détroit d'Hudson) links the Atlantic Ocean and Labrador Sea to Hudson Bay in Canada. This strait lies between Baffin Island and Nunavik, with its eastern entrance marked by Cape Chidley in Newfoundland and Labrador and Resolution Island off Baffin Island. The strait is about 750 km long with an average width of 125 km, varying from 70 km at the eastern entrance to 240 km at Deception Bay. English navigator Sir Martin Frobisher was the first European to report entering the strait, in 1578. He named a tidal rip at the entrance the Furious Overfall and called the strait ''Mistaken Strait'', since he felt it held less promise as an entrance to the Northwest Passage than the body of water that was later named Frobisher Bay. John Davis sailed by the entrance to the strait during his voyage of 1587. The first European to explore the strait was George Weymouth who sailed 300 nautical miles beyond the Furious Overfall in 1602. The strait was ...
