95-504: The area is the traditional territory of the Algonquin First Nation . English Canadians began settling in the 1700s in towns like Arundel and Harrington and St. Columban and Clyde, today's La Conception. French Canadians began settlement in the first half of the 19th century, establishing an agricultural presence throughout the valleys. During the 20th century, the area also became a popular tourist destination, based on

190-492: A World Heritage Site for their geological value, four of them are considered of "Outstanding Universal Value" based on their cultural and natural criteria: Þingvellir , Iceland; Landscape of the Pico Island Vineyard Culture , Portugal; Gough and Inaccessible Islands , United Kingdom; and Brazilian Atlantic Islands: Fernando de Noronha and Atol das Rocas Reserves, Brazil. Continental shelves in

285-506: A Navy Sonic Depth Finder to draw a continuous map across the bed of the Atlantic. This involved little guesswork because the idea of sonar is straightforward with pulses being sent from the vessel, which bounce off the ocean floor, then return to the vessel. The deep ocean floor is thought to be fairly flat with occasional deeps, abyssal plains , trenches , seamounts , basins , plateaus , canyons , and some guyots . Various shelves along

380-721: A branch of the Gulf Stream which flows northward from the Grand Banks ; and the Subpolar Front , an extension of the North Atlantic Current, a wide, vaguely defined region separating the subtropical gyre from the subpolar gyre. This system of currents transports warm water into the North Atlantic, without which temperatures in the North Atlantic and Europe would plunge dramatically. North of

475-406: A cottage and lake culture in the summer, and a downhill and cross-country ski culture in the winter. Ski resorts include Saint-Sauveur and Mont Tremblant . The Laurentides offer a weekend escape for Montrealers and tourists from New England to Ontario, and with the building of a major highway through the area in the 1970s ( Autoroute 15 ), the area has experienced much growth. Its largest city

570-608: A large Kanienkehaka (Mohawk) war party attacked the Kitcisìpiriniwak living near Trois-Rivières and almost exterminated them. The Kitcisìpiriniwak were still at Morrison Island in 1650 and inspired respect with their 400 warriors. When the French retreated from Wendat ( Huron ) country that year, Tessouat was reported to have had the superior of the Jesuit mission suspended by his armpits because he refused to offer him

665-428: A poultice of the gum or needles of Abies balsamea to open sores, insect bites, boils and infections. The needles are a sudatory for women after childbirth and are infused for a laxative tea, while the roots treat heart disease. At the time of their first meeting with the French in 1603, the various Algonquin bands probably had a combined population somewhere in the neighborhood of 6,000. The British estimate in 1768

760-671: A second group, the Wàwàckeciriniwak . However, by 1615, they applied the name to all of the Algonquin bands living along the Ottawa River. Because of keen interest by tribes to gain control of the lower Ottawa River , the Kitcisìpiriniwak and the Wàwàckeciriniwak came under fierce opposition. These two large groups allied together, under the leadership of Sachem (Carolus) Charles Pachirini, to maintain

855-416: A weak Intertropical Convergence Zone , South Atlantic tropical cyclones are rare. The Atlantic Ocean is underlain mostly by dense mafic oceanic crust made up of basalt and gabbro and overlain by fine clay, silt and siliceous ooze on the abyssal plain. The continental margins and continental shelf mark lower density, but greater thickness felsic continental rock that is often much older than that of

950-630: Is Saint-Jérôme , in its extreme southeast, with a 2011 census population of 68,456 inhabitants. This Quebec location article is a stub . You can help Misplaced Pages by expanding it . Algonquin people The Algonquin people are an Indigenous people who now live in Eastern Canada . They speak the Algonquin language , which is part of the Algonquian language family. Culturally and linguistically, they are closely related to

1045-621: Is a complex of four water masses, two that form by deep convection in the open ocean – classical and upper Labrador sea water – and two that form from the inflow of dense water across the Greenland-Iceland-Scotland sill – Denmark Strait and Iceland-Scotland overflow water. Along its path across Earth the composition of the NADW is affected by other water masses, especially Antarctic bottom water and Mediterranean overflow water. The NADW

1140-708: Is considered one of several divergent dialects of the Anishinaabe languages. Among younger speakers, the Algonquin language has experienced strong word borrowings from the Cree language . Traditionally, the Algonquins lived in either birch bark or wooden mìkiwàms . Traditionally, the Algonquins were practitioners of Midewiwin (the Path of the Heart). They believed they were surrounded by many manitòk or spirits in

1235-467: Is fed by a flow of warm shallow water into the northern North Atlantic which is responsible for the anomalous warm climate in Europe. Changes in the formation of NADW have been linked to global climate changes in the past. Since human-made substances were introduced into the environment, the path of the NADW can be traced throughout its course by measuring tritium and radiocarbon from nuclear weapon tests in

1330-498: Is found off the eastern coast of Canada. Surface water temperatures, which vary with latitude, current systems, and season and reflect the latitudinal distribution of solar energy, range from below −2 °C (28 °F) to over 30 °C (86 °F). Maximum temperatures occur north of the equator, and minimum values are found in the polar regions. In the middle latitudes, the area of maximum temperature variations, values may vary by 7–8 °C (13–14 °F). From October to June

1425-575: Is interrupted by larger transform faults at two places: the Romanche Trench near the Equator and the Gibbs fracture zone at 53°N . The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. The MAR rises 2–3 km (1.2–1.9 mi) above the surrounding ocean floor and its rift valley is the divergent boundary between

1520-854: Is intersected by two perpendicular ridges: the Azores–Gibraltar Transform Fault , the boundary between the Nubian and Eurasian plates , intersects the MAR at the Azores triple junction , on either side of the Azores microplate, near the 40°N . A much vaguer, nameless boundary, between the North American and South American plates, intersects the MAR near or just north of the Fifteen-Twenty fracture zone , approximately at 16°N . In

1615-729: Is now northern and central Brazil. The formation of the Central American Isthmus closed the Central American Seaway at the end of the Pliocene 2.8 Ma ago. The formation of the isthmus resulted in the migration and extinction of many land-living animals, known as the Great American Interchange , but the closure of the seaway resulted in a "Great American Schism" as it affected ocean currents, salinity, and temperatures in both

1710-794: Is now the Carpathian region, that were similar to the Sargasso Sea. It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in

1805-678: The Omàmiwinini identity and territory. The Iroquois Confederacy (Haudenosaunee) drove Algonquins from their lands. The Haudenosaunee were aided by having been traded arms by the Dutch , and later by the English . The Haudenosaunee and the English defeated the French and Algonquins in the 1620s, and, led by Sir David Kirke , occupied New France . In 1623, having realized the occupation of New France demonstrated French colonial vulnerability,

1900-985: The Iliad and the Odyssey , this all-encompassing ocean was instead known as Oceanus , the gigantic river that encircled the world; in contrast to the enclosed seas well known to the Greeks: the Mediterranean and the Black Sea. In contrast, the term "Atlantic" originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the West African coast. The term " Aethiopian Ocean ", derived from Ancient Ethiopia ,

1995-797: The Age of Discovery , it was known for separating the New World of the Americas ( North America and South America ) from the Old World of Afro-Eurasia ( Africa , Asia , and Europe ). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were

2090-564: The Carpathian Basin from where it migrated over Sicily to the central Atlantic where it evolved into modern species of the Sargasso Sea. The location of the spawning ground for European eels remained unknown for decades . In the early 19th century it was discovered that the southern Sargasso Sea is the spawning ground for both the European and American eel and that the former migrate more than 5,000 km (3,100 mi) and

2185-610: The Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like the United States and Brazil , both increased in degree during the early 20th century, and while no major military conflicts have taken place in the Atlantic recently, the ocean remains a core component of trade around the world. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to

2280-530: The Equator . The oldest known mentions of an "Atlantic" sea come from Stesichorus around mid-sixth century BC (Sch. A. R. 1. 211): Atlantikôi pelágei (Ancient Greek: Ἀτλαντικῷ πελάγει , ' the Atlantic sea ' , etym . ' Sea of Atlas ' ) and in The Histories of Herodotus around 450 BC (Hdt. 1.202.4): Atlantis thalassa (Ancient Greek: Ἀτλαντὶς θάλασσα , ' Sea of Atlas ' or '

2375-597: The Great Lakes , where the climate allows for a longer growing season. Notable indigenous crops historically farmed by Algonquins are the sunflower and tobacco . Around 800CE, Eastern Algonquins adopted maize agriculture from their neighbors in the interior. Even among groups who mainly hunted, agricultural products were an important source of food. They obtained what was needed by trading with or raiding societies that practiced more agriculture. Eastern Algonquins created pots that could withstand not only thermal stress but

2470-474: The Icelandic Low produces frequent storms. Icebergs are common from early February to the end of July across the shipping lanes near the Grand Banks of Newfoundland . The ice season is longer in the polar regions, but there is little shipping in those areas. Hurricanes are a hazard in the western parts of the North Atlantic during the summer and autumn. Due to a consistently strong wind shear and

2565-684: The North American and Eurasian plates in the North Atlantic and the South American and African plates in the South Atlantic. The MAR produces basaltic volcanoes in Eyjafjallajökull , Iceland, and pillow lava on the ocean floor. The depth of water at the apex of the ridge is less than 2,700 m (1,500 fathoms ; 8,900  ft ) in most places, while the bottom of the ridge is three times as deep. The MAR

2660-616: The North Atlantic Drift is thought to have at least some influence on climate. For example, the Gulf Stream helps moderate winter temperatures along the coastline of southeastern North America, keeping it warmer in winter along the coast than inland areas. The Gulf Stream also keeps extreme temperatures from occurring on the Florida Peninsula. In the higher latitudes, the North Atlantic Drift, warms

2755-514: The North Atlantic oscillation , occurs. On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values. Although the lowest salinity values are just north of the equator (because of heavy tropical rainfall), in general,

2850-479: The Odawa , Potawatomi , Ojibwe (including Oji-Cree ), Mississaugas , and Nipissing , with whom they form the larger Anicinàpe (Anishinaabeg). Algonquins are known by many names , including Omàmiwinini (plural: Omàmiwininiwak , "downstream man/men") and Abitibiwinni (pl.: Abitibiwinnik "men [living] halfway across the water") or the more generalised name of Anicinàpe . Though known by several names in

2945-555: The Scotia Sea , and other tributary water bodies. Including these marginal seas the coast line of the Atlantic measures 111,866 km (69,510 mi) compared to 135,663 km (84,297 mi) for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km (41,100,000 sq mi) or 23.5% of the global ocean and has a volume of 310,410,900 km (74,471,500 cu mi) or 23.3% of

3040-638: The meridional overturning circulation (MOC), the northward heat transport of which is threatened by anthropogenic climate change. Large variations in the subpolar gyre on a decade-century scale, associated with the North Atlantic oscillation , are especially pronounced in Labrador Sea Water , the upper layers of the MOC. The South Atlantic is dominated by the anti-cyclonic southern subtropical gyre. The South Atlantic Central Water originates in this gyre, while Antarctic Intermediate Water originates in

3135-458: The thermocline of the subtropical gyre. The Sargasso Sea in the western North Atlantic can be defined as the area where two species of Sargassum ( S. fluitans and natans ) float, an area 4,000 km (2,500 mi) wide and encircled by the Gulf Stream , North Atlantic Drift , and North Equatorial Current . This population of seaweed probably originated from Tertiary ancestors on

3230-756: The 1820s and 1930s, the lumber industry began to move up the Ottawa valley. Algonquin became increasingly displaced as a result. Beginning in the 1820s, Algonquin Grand Chief Constant Pinesi sent a series of letters petitioning the British Crown for Algonquin Territorial Recognition previously agreed upon in the Treaties of 1701 and 1764, ratified by Algonquins and the British Crown. No responses were forthcoming from

3325-578: The 1870s, the Challenger expedition discovered parts of what is now known as the Mid-Atlantic Ridge, or: An elevated ridge rising to an average height of about 1,900 fathoms [3,500 m; 11,400 ft] below the surface traverses the basins of the North and South Atlantic in a meridianal direction from Cape Farewell, probably its far south at least as Gough Island, following roughly

3420-618: The 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean. The Atlantic has irregular coasts indented by numerous bays, gulfs and seas. These include the Baltic Sea , Black Sea , Caribbean Sea , Davis Strait , Denmark Strait , part of the Drake Passage , Gulf of Mexico , Labrador Sea , Mediterranean Sea , North Sea , Norwegian Sea , almost all of

3515-485: The 1960s and CFCs . The clockwise warm-water North Atlantic Gyre occupies the northern Atlantic, and the counter-clockwise warm-water South Atlantic Gyre appears in the southern Atlantic. In the North Atlantic, surface circulation is dominated by three inter-connected currents: the Gulf Stream which flows north-east from the North American coast at Cape Hatteras ; the North Atlantic Current ,

3610-457: The 19th Century progressed. Many of these Algonquins were not recognized as "Status Indians". The location of the former Lake of Two Mountains Band came to be known as Kahnesatake. As a large majority of the Algonquin population had left the area, with only the Christian Haudenosaunee and a few Algonquins remaining, it became recognized as a Mohawk reserve (though many in the community have at least partial Algonquin Ancestry). Algonquins living in

3705-423: The Algonquin census of Trois Rivieres in the mid-19th century). The Lake of Two Mountains band of Algonquins were located just west of the Island of Montreal, and were signatories to the Great Peace of Montreal in 1701. The Sulpician Mission of the Mountain was founded at Montreal in 1677. In 1717, the King of France granted the Mohawk in Quebec a tract of land 9 miles long by 9 miles wide about 40 miles to

3800-407: The Atlantic are wide off Newfoundland, southernmost South America, and northeastern Europe. In the western Atlantic carbonate platforms dominate large areas, for example, the Blake Plateau and Bermuda Rise . The Atlantic is surrounded by passive margins except at a few locations where active margins form deep trenches : the Puerto Rico Trench (8,376 m or 27,480 ft maximum depth) in

3895-468: The Atlantic include the Challenger expedition and the German Meteor expedition ; as of 2001 , Columbia University 's Lamont–Doherty Earth Observatory and the United States Navy Hydrographic Office conduct research on the ocean. The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2,000 m (6,600 ft) along most of its length, but

Coarse sand, boulders, and rocks were transported into some areas, such as off the coast of Nova Scotia or the Gulf of Maine during the Pleistocene ice ages. The break-up of Pangaea began in the central Atlantic, between North America and Northwest Africa, where rift basins opened during

4275-509: The British, and the Algonquins began to be relegated to a string of small reserves beginning in the 1830s. Algonquins who agreed to move to these reserves or joined other historical bands were federally "recognized". Others maintained their attachment to the traditional territory and fur trading, and chose not to re-locate. These Algonquins were later called "stragglers" in the Ottawa and Pontiac counties with some eventually settling in small towns such as Renfrew , Whitney , and Eganville as

4370-404: The European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth , floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish , a predator with algae-like appendages which hovers motionless among the Sargassum . Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what

4465-435: The Europeans, especially the French and Dutch , the Algonquin nations became active in the fur trade . This led them to fight against the powerful Haudenosaunee , whose confederacy was based in present-day New York. In 1570, the Algonquins formed an alliance with the Innu (Montagnais) to the east, whose territory extended to the ocean. Culturally, Omàmìwininì (Algonquin) and the Mississaugas (Michi Saagiig) were not part of

4560-417: The French began to trade muskets to Algonquins and their allies. French Jesuits began to seek Algonquin conversions to Roman Catholicism . Through all of these years, the Haudenosaunee never attacked the Kitcisìpirinik fortress. But, in 1642, they made a surprise winter raid, attacking Algonquins while most of their warriors were absent, and causing severe casualties. On March 6, 1647 ( Ash Wednesday ),

4655-405: The Government of Canada and the Government of Ontario was reached in 2015. Many Algonquins dispute both the validity of both this settlement and the organization of the Algonquins of Ontario as a whole. In 2000, Algonquins from Timiskaming First Nation played a significant part in the local popular opposition to the plan to convert Adams Mine into a garbage dump. Historical Algonquin society

4750-405: The Late Triassic and Early Jurassic. This period also saw the first stages of the uplift of the Atlas Mountains. The exact timing is controversial with estimates ranging from 200 to 170 Ma. The opening of the Atlantic Ocean coincided with the initial break-up of the supercontinent Pangaea , both of which were initiated by the eruption of the Central Atlantic Magmatic Province (CAMP), one of

4845-468: The North Atlantic Gyre, the cyclonic North Atlantic Subpolar Gyre plays a key role in climate variability. It is governed by ocean currents from marginal seas and regional topography, rather than being steered by wind, both in the deep ocean and at sea level. The subpolar gyre forms an important part of the global thermohaline circulation . Its eastern portion includes eddying branches of the North Atlantic Current which transport warm, saline waters from

4940-444: The Ojibwe–Odawa–Potawatomi alliance known as the Council of Three Fires , though they did maintain close ties. Omàmìwininìwak (Algonquins) maintained stronger cultural ties with the Wendat , Abenaki , Atikamekw , and Cree , along with the Innu, as related above. Algonquin first met Europeans when Samuel de Champlain came upon a party led by the Kitcisìpirini Chief Tessouat at Tadoussac , in eastern present-day Quebec, in

5035-437: The South Atlantic, and the "Atmospheric Bridge", which evaporates subtropical Atlantic waters and exports it to the Pacific. The Atlantic Ocean consists of four major, upper water masses with distinct temperature and salinity. The Atlantic subarctic upper water in the northernmost North Atlantic is the source for subarctic intermediate water and North Atlantic intermediate water. North Atlantic central water can be divided into

5130-476: The Sulpicians claimed total control of the land, gaining a deed that gave them legal title. But the Haudenosaunee (Mohawks), Algonquins, and Nipissing understood that this land was being held in trust for them. The Sulpician mission village of Lake of Two Mountains (Lac des Deux Montagnes), west of Montreal, became known both by its Algonquin language name Oka (meaning "pickerel"), and the Mohawk language Kanehsatà:ke ("sandy place"); however, Algonquin also called

5225-412: The atmosphere over the oceans, keeping the British Isles and northwestern Europe mild and cloudy, and not severely cold in winter, like other locations at the same high latitude. The cold water currents contribute to heavy fog off the coast of eastern Canada (the Grand Banks of Newfoundland area) and Africa's northwestern coast. In general, winds transport moisture and air over land areas. Every winter,

5320-445: The band's clan leaders. Champlain needed to cultivate relationships with numerous chiefs and clan leaders. From 1603, some of the Algonquins allied with the French under Champlain. This alliance proved useful to the Algonquin, who previously had little to no access to European firearms. Champlain made his first exploration of the Ottawa River during May 1613 and reached the fortified Kitcisìpirini village at Morrison Island . Unlike

5415-407: The continuing use of the river for cultural exchange throughout the Canadian Shield and beyond. Beginning at the latest in c. 1 CE, the Algonquin Nation inhabited the islands and shores along Kitcisìpi (Algonquin Language name translating to The Great River, known now as the Ottawa River ). By the 17th century European Explorers found them well established as a hunter-gatherer society in control of

5510-474: The customary presents for being allowed to travel through Algonquin territory. Some joined the mission at Sillery, where they were mostly destroyed by an infectious disease epidemic by 1676. Encouraged by the French, others remained at Trois-Rivières. Their settlement at nearby Pointe-du-Lac continued until about 1830. That year the last 14 families, numbering about 50, moved to Kanesatake near Oka . (The families who stayed in Trois Rivieres can be found in

5605-425: The east, and the Americas 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, the northern and southern Atlantic, by

5700-431: The east, the boundaries of the ocean proper are Europe: the Strait of Gibraltar (where it connects with the Mediterranean Sea  – one of its marginal seas  – and, in turn, the Black Sea , both of which also touch upon Asia) and Africa. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridian , running south from Cape Agulhas to Antarctica defines its border. In

Columbus' expedition ushered in an age of exploration and colonization of the Americas by European powers , most notably Portugal , Spain , France , and the United Kingdom . From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and

5985-454: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of

Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into

6270-454: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss

Theoliitic dikes , sills , and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5 × 10  km (1.7 × 10  sq mi) of which 2.5 × 10  km (9.7 × 10  sq mi) covered what

6650-445: The natural world. French missionaries converted many Algonquins to Catholicism in the 17th and 18th centuries. Today, many Algonquin practice traditional Midewiwin or a syncretic merging of Christianity and Midewiwin. In the oral history of the Great Anishinaabeg Migration, the Algonquins say they migrated from the Atlantic coast. Together with other Anicinàpek , they arrived at the "First Stopping Place" near Montreal . While

6745-502: The north to become the source for North Atlantic deep water, south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and a large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic deep water (NADW)

6840-569: The northern regions of Algonquin Territory gradually moved to towns such as present day Témiscaming , and Mattawa , amongst others in Ontario and Quebec, as territorial encroachment by settlers, and lumber and resource companies increased throughout the 19th and 20th centuries or various reserves set up in their traditional territories. In recent years, tensions with the lumber industry have flared up again among Algonquin communities, in response to

Sulpician Missionaries set up a trading post at the village in 1721 and attracted a large number of Haudenosaunee converts to Christianity to the area. The settlement of Kanesatake was formally founded as a Catholic mission , a seigneury under the supervision of the Sulpician Order for 300 Christian Mohawk, about 100 Algonquins, and approximately 250 Nipissing peoples "in their care". Over time

Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across

7125-680: The other Anicinàpe peoples continued their journey up the St. Lawrence River , the Algonquins settled along Kitcisìpi (the Ottawa River ), a long-important highway for commerce, cultural exchange and transportation. Algonquin identity, though, was not fully realized until after the dividing of the Anicinàpek at the "Third Stopping Place". Scholars have used the oral histories, archeology, and linguistics to estimate this took place about 2000 years ago, near present-day Detroit . After contact with

7220-474: The other Algonquin communities, the Kitcisìpiriniwak did not change location with the seasons. They had chosen a strategic point astride the trade route between the Great Lakes and the St. Lawrence River. They prospered through the collection of beaver pelts from Indigenous traders passing through their territory. They also were proud of their corn fields. At first, the French used the term "Algonquin" only for

7315-627: The outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics . Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated

7410-522: The past, such as Algoumequin , the most common term "Algonquin" has been suggested to derive from the Maliseet word elakómkwik ( IPA: [ɛlæˈɡomoɡwik] ): "they are our relatives/allies." The much larger heterogeneous group of Algonquian -speaking peoples, who, according to Brian Conwell, stretch from Virginia to the Rocky Mountains and north to Hudson Bay , was named after

7505-651: The pond" or "on the other side of the pond" or "across the pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in a pamphlet released during the reign of Charles I , and reproduced in 1869 in Nehemiah Wallington 's Historical Notices of Events Occurring Chiefly in The Reign of Charles I , where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank , Charles I's Secretary of State . The International Hydrographic Organization (IHO) defined

7600-469: The practice of clear-cutting. In Ontario, an Algonquin land claim has been ongoing since 1983, encompassing much of the southeastern part of the province, stretching from near North Bay to near Hawkesbury and including Ottawa , Pembroke , and most of Algonquin Provincial Park . The Algonquins never relinquished title to this area. An agreement-in-principle between the Algonquins of Ontario,

7695-445: The river. On Morrison Island, at the location where 5,000-year-old copper artifacts were discovered, the Kitcisìpiriniwak levied a toll on canoe flotillas descending the river. Algonquins of Quebec gather the berries of Ribes glandulosum and Viburnum nudum var. cassinoides as food, and eat and sell the fruit of Vaccinium myrtilloides . They take an infusion of Epigaea repens leaves for kidney disorders and apply

7790-438: The seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and is situated off the west coast of Africa and the east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and

7885-551: The subtropics to the northeastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50  Sv ) current which flows around the continental margins of the Labrador Sea . A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in turn, feeds

7980-543: The summer of 1603. They were celebrating a recent victory over the Iroquois , with the allied Montagnais and Etchemins ( Malecite ). Champlain did not understand that Algonquins were socially united by a strong totem /clan system rather than the European-styled political concept of nationhood. The several Algonquin bands each had its own chief. Within each band, the chief depended on political approval from each of

8075-421: The surface is usually covered with sea ice in the Labrador Sea , Denmark Strait , and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as

8170-480: The total volume of the Earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km (31,570,000 sq mi) and has a volume of 305,811,900 km (73,368,200 cu mi). The North Atlantic covers 41,490,000 km (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and

8265-656: The tribe. Most Algonquins live in Quebec . The nine recognized status Algonquin bands in that province and one in Ontario have a combined population of about 17,002. In addition, there are additional non-status communities, some of which are controversial. Algonquins are original Indigenous People of southern Quebec and eastern Ontario in Canada. Many Algonquins still speak the Algonquin language, called generally Anicinàpemowin or specifically Omàmiwininìmowin . The language

8360-636: The upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer . The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below

8455-715: The village as Ganashtaageng after the Mohawk language name. Algonquin warriors continued to fight in alliance with France until the British conquest of Quebec in 1760, during the Seven Years' War. After the British took over colonial rule of Canada, their officials sought to make allies of the First Nations, and the Algonquin, along with many other First Nations signed the Royal Proclamation of 1763 , which

8550-424: The western Atlantic and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off northeastern North America, western Europe, and northwestern Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used

8645-533: Was 1,500. As of 2000, there are close to 8,000 Algonquins in Canada, organized into ten separate First Nations: nine in Quebec and one in Ontario. Algonquian Nations documented as early as 1630: Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceanic divisions , with an area of about 85,133,000 km (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area. During

8740-494: Was applied to the southern Atlantic as late as the mid-19th century. During the Age of Discovery , the Atlantic was also known to English cartographers as the Great Western Ocean . The pond is a term often used by British and American speakers in reference to the northern Atlantic Ocean, as a form of meiosis , or ironic understatement. It is used mostly when referring to events or circumstances "on this side of

8835-415: Was built with wood and covered with an envelope made of leather or material. The baby was standing up with his feet resting on a small board. The mother would then put the tikinàgan on her back. This allowed the infant to look around and observe his surroundings. The child was kept close to the mother but also had much stimulation. Algonquian-speaking people also practiced agriculture, particularly south of

8930-485: Was largely hunting and fishing-based. Being primarily a hunting nation, the people emphasized mobility. They used materials that were light and easy to transport. Canoes were made of birch bark , sewed with spruce roots and rendered waterproof by the application of heated spruce resin and bear grease. During winter, toboggans were used to transport material, and people used snowshoes to get around. The women used tikinaagan (cradleboards) to carry their babies. It

9025-694: Was then ratified in 1764 as the Treaty of Niagara . Subsequently, fighting on behalf of the British Crown, Algonquins took part in the Barry St Leger campaign during the American Revolutionary War . Following the American Revolutionary War , and later the War of 1812 , the Lake of Two Mountains Algonquins found their territory increasingly encroached on by Loyalist settlers. Beginning in
