Montmagny Seamount
Montmagny Seamount, formerly known as Minia Seamount, is an undersea mountain in the North Atlantic Ocean, located about south of Cape Race in Canadian waters off Atlantic Canada. It rises to a height of over and has an areal extent of , making it slightly larger than the Quebec city of Montreal. Montmagny is one of the seven named Fogo Seamounts. It was originally named ''Minia Seamount'' after a Canadian cable ship that helped search for bodies from the ''Titanic RMS ''Titanic'' was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United ...'' disaster. However, this name had already been in use for a seamount further to the northeast and was therefore renamed in 1997 to ''Montmagny Seamount'' after the Canadian steamship SS ''Montmagny''. This steamship participated in two recovery missions after the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Cape Race
Cape Race is a point of land located at the southeastern tip of the Avalon Peninsula on the island of Newfoundland, in Newfoundland and Labrador, Canada. Its name is thought to come from the original Portuguese name for this cape, "Raso", meaning flat or low-lying. The Cape appeared on early sixteenth century maps as Cabo Raso and its name may derive from a cape of the same name at the mouth of the Tagus River in Portugal. The cape was the location of the Cape Race LORAN-C transmitter until the system was decommissioned in 2010. It is also home to the Cape Race Lighthouse, notable for having received the distress call from the RMS ''Titanic''. Geography Dense fog, rocky coasts, and its proximity to trans-Atlantic shipping routes have resulted in many shipwrecks near Cape Race over the years. One of the most famous was the . Cape Race is a flat, barren point of land jutting out into the Atlantic Ocean, its cliffs rising almost vertically to above sea level. On average it ...

Fogo Seamounts
The Fogo Seamounts, also called the Fogo Seamount Chain, are a group of undersea mountains southeast of the Grand Banks of Newfoundland in the North Atlantic Ocean. This seamount chain, lying approximately offshore from the island of Newfoundland, consists of several submarine volcanoes that have been extinct for millions of years. They are one of the few seamount chains located in Canadian waters off the coast of Atlantic Canada. Geology The Fogo Seamounts are of Early Cretaceous age and form a broad zone of basaltic volcanoes off the continental shelf of Atlantic Canada. This zone narrows in the northwest and widens to in the southeast, a pattern that differs from the adjacent Newfoundland and New England seamounts which form narrow linear arrangements typical of seamount chains. Therefore, it is possible that the Fogo Seamounts formed in a more complex manner than the Newfoundland and New England seamounts. Basalts of the Fogo Seamounts chemically range from slightly alkalic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Submarine Volcano
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth.Martin R. Speight, Peter A. Henderson, "Marine Ecology: Concepts and Applications", John Wiley & Sons, 2013. . Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption. The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct) of which some 75,000 rise more than 1 km above the seabed. Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes. Effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlantic Canada
Atlantic Canada, also called the Atlantic provinces (french: provinces de l'Atlantique), is the region of Eastern Canada comprising the provinces located on the Atlantic coast, excluding Quebec. The four provinces are New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. As of 2021, the landmass of the four Atlantic provinces was approximately 488,000 km2, and had a population of over 2.4 million people. The provinces combined had an approximate GDP of $121.888 billion in 2011. The term ''Atlantic Canada'' was popularized following the admission of Newfoundland as a Canadian province in 1949. History The first premier of Newfoundland, Joey Smallwood, coined the term "Atlantic Canada" when Newfoundland joined Canada in 1949. He believed that it would have been presumptuous for Newfoundland to assume that it could include itself within the existing term "Maritime provinces," used to describe the cultural similarities shared by New Brunswick, Prince ...

Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...
