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
2480-794: 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

His eldest son, Pedro I of Brazil , briefly became Pedro IV of Portugal , but neither the Portuguese nor Brazilians wanted a unified monarchy; consequently, Pedro abdicated the Portuguese crown in favor of his 7-year-old daughter, Maria da Glória , on the condition that when she came of age she would marry his brother, Miguel . Dissatisfaction at Pedro's constitutional reforms led
9796-469: The country's political decline that led to the Iberian Union (1580-1640), a period in which Portugal was united under Spanish rule. While maintaining a degree of self-governance, the union strained Portugal’s autonomy and drew it into conflicts with European powers which targeted Portuguese territories and trade routes. Portugal's prior opulence was further exacerbated by a series of events, such as
9920-460: The earthquake, Joseph I gave his prime minister more power, and Carvalho de Melo became an enlightened despot . In 1758 Joseph I was wounded in an attempted assassination. The Marquis of Távora , several members of his family and even servants were tortured and executed in public with extreme brutality (even by the standards of the time), as alleged part of the Távora affair . The following year,
10044-667: 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
10168-544: The eastern and western North Atlantic central water since the western part is strongly affected by the Gulf Stream and therefore the upper layer is closer to underlying fresher subpolar intermediate water. The eastern water is saltier because of its proximity to Mediterranean water. North Atlantic central water flows into South Atlantic central water at 15°N . There are five intermediate waters: four low-salinity waters formed at subpolar latitudes and one high-salinity formed through evaporation. Arctic intermediate water flows from
10292-532: The empire. South Atlantic 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 the Age of Discovery , it was known for separating the New World of the Americas ( North America and South America ) from
10416-408: The empire. Roman occupation suffered a setback in 155 BC, when a rebellion began in the north. The Lusitanians and other native tribes, under the leadership of Viriathus , wrested control of all of western Iberia. Rome sent legions to quell the rebellion but were unsuccessful. Roman leaders bribed Viriathus's allies to kill him in 139 BC; he was replaced by Tautalus . In 27 BC, Lusitania gained
10540-753: 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 , was applied to the southern Atlantic as late as the mid-19th century. During
10664-603: The first cities he founded is Vimaranes, known today as Guimarães – "birthplace of the Portuguese nation" or the "cradle city". After annexing the County of Portugal into one of the counties that made up the Kingdom of Asturias , King Alfonso III of Asturias knighted Vímara Peres, in 868, as the First Count of Portus Cale (Portugal). The region became known as Portucale , Portugale , and simultaneously Portugália . With
10788-408: The first millennium BC, several waves of Celts invaded Portugal from Central Europe and intermarried with the local populations to form several different ethnic groups. The Celtic presence is patent in archaeological and linguistic evidence. They dominated most of northern and central Portugal, while the south maintained its older character (believed non-Indo-European, likely related to Basque ) until
10912-548: The first millennium BCE , with Phoenician and later Punic influence reaching the south during the same period. The region came under Roman control in the second century BCE, followed by a succession of Germanic peoples and the Alans from the fifth to eighth centuries CE. Muslims conquered most of the Iberian Peninsula in the eighth century CE, but were gradually expelled by the Christian Reconquista over
11036-458: The forced abdication of Alfonso III in 910, the Kingdom of Asturias split into three separate kingdoms; they were reunited in 924 under the crown of León . In 1093 Alfonso VI of León bestowed the county to Henry of Burgundy and married him to his daughter, Teresa of León . Henry thus became Henry, Count of Portugal and based his newly formed county from Bracara Augusta (modern Braga ). At
11160-503: The influx of gold into the royal treasury, supplied largely by the royal fifth (tax on precious metals) from the Portuguese colonies of Brazil and Maranhão . Most estimates place the number of Portuguese migrants to Colonial Brazil during the gold rush of the 18th century at 600,000. This represented one of the largest movements of European populations to their colonies, during colonial times. In 1738 Sebastião José de Carvalho e Melo , later ennobled as 1st Marquis of Pombal , began
11284-807: 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 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 , '
11408-694: The joining of the two crowns deprived Portugal of an independent foreign policy, and led to its involvement in the Eighty Years' War between Spain and the Netherlands. War led to a deterioration of relations with Portugal's oldest ally, England , and the loss of Hormuz , a strategic trading post located between Iran and Oman . From 1595 to 1663 the Dutch-Portuguese War primarily involved Dutch companies invading Portuguese colonies and commercial interests in Brazil, Africa, India and
11532-517: 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
11656-666: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To
11780-647: The local inhabitants. St. Martin of Braga was a particularly influential evangelist. In 429, the Visigoths moved south to expel the Alans and Vandals and founded a kingdom with its capital in Toledo . From 470, conflict between the Suebi and Visigoths increased. In 585, the Visigothic King Liuvigild conquered Braga and annexed Gallaecia; the Iberian Peninsula was unified under a Visigothic Kingdom . A new class emerged, unknown in Roman times:
11904-501: The lowest values are in the high latitudes and along coasts where large rivers enter. 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
12028-514: 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
12152-664: The maximum depth, the Milwaukee Deep in the Puerto Rico Trench , is 8,376 m (27,480 ft). Top large seas: The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S . Expeditions to explore the bathymertry of
12276-640: The most consequential. 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 the Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like
12400-732: The most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event , one of Earth's major extinction events . 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
12524-532: The next several centuries. Modern Portugal began taking shape during this period, initially as a county of the Christian Kingdom of León in 868, and ultimately as an independent Kingdom with the Treaty of Zamora in 1143. During the Age of Discovery , the Kingdom of Portugal established itself as a major economic and political power, largely through its maritime empire, which extended mostly along
12648-571: 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)
12772-425: The ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. 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
12896-627: 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
13020-595: 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
13144-552: The reign of King José I, he banned the import of black slaves into mainland Portugal and India, not for humanitarian reasons, but because they were a necessary work force in Brazil. At the same time, he encouraged the trade of black slaves ("the pieces", in the terms of that time) to that colony, and with the support and direct involvement of the Marquis of Pombal, two companies were founded - the Companhia do Grão-Pará e Maranhão and
13268-438: 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
13392-539: The status of Roman province . Later, a northern province was separated from the province of Tarraconensis , under Emperor Diocletian 's reforms, known as Gallaecia . There are still ruins of castros ( hill forts ) and remains of the Castro culture , like Conímbriga , Mirobriga and Briteiros . In 409, with the decline of the Roman Empire , the Iberian Peninsula was occupied by Germanic tribes . In 411, with
13516-551: 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
13640-421: 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
13764-669: The territories corresponding to modern Portugal. As elsewhere in Western Europe, there was a sharp decline in urban life during the Dark Ages . Roman institutions disappeared in the wake of the Germanic invasions with the exception of ecclesiastical organizations, which were fostered by the Suebi in the fifth century and adopted by the Visigoths afterwards. Although the Suebi and Visigoths were initially followers of Arianism and Priscillianism , they adopted Catholicism from
13888-479: The third level and subsequently earning a contract with C.D. Nacional of division two , where he appeared sparingly over the course of three campaigns, being relegated in his second. In the 2001 summer, after a failed second stint with Nacional, Alves moved to another team in Madeira , A.D. Camacha , netting 16 goals in his only season. He then signed for his fifth club in the region, A.D. Pontassolense (also in
14012-553: The third tier), where he repeated individual numbers in his first year. In 2003–04 , 32-year-old Alves scored 15 goals for Pontassolense, thus becoming the third division – south zone – runner-up topscorer behind S.C. Olhanense 's Edinho . He only found the net five times in the following campaign and, subsequently, moved to amateur football where he played a couple of years for two sides before retiring. Portugal – in Europe (green & dark grey) – in
14136-520: The throne of Portugal. John of Aviz, later John I of Portugal , defeated the Castilians in the Battle of Aljubarrota , and the House of Aviz became the ruling house. The new ruling dynasty led Portugal to the limelight of European politics and culture. They created and sponsored literature, such as a history of Portugal, by Fernão Lopes . Portugal spearheaded European exploration of the world and
14260-428: 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
14384-637: 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
14508-575: The vast Umayyad Caliphate's empire of Damascus , until its collapse in 750. That year the west of the empire gained its independence under Abd-ar-Rahman I with the establishment of the Emirate of Córdoba . The Emirate became the Caliphate of Córdoba in 929, until its dissolution in 1031, into 23 small kingdoms, called Taifa kingdoms. The governors of the taifas proclaimed themselves Emir of their provinces and established diplomatic relations with
14632-586: The war of Christian reconquest. At the end of the 9th century, the region of Portugal between the rivers Minho and Douro, was reconquered from the Moors by nobleman and knight Vímara Peres on the orders of King Alfonso III of Asturias . Finding many towns deserted, he decided to repopulate and rebuild them. Vímara Peres elevated the region to the status of County , naming it the County of Portugal after its major port city – Portus Cale or modern Porto . One of
14756-424: 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
14880-437: The wine's quality. This was the first attempt to control wine quality and production in Europe. He imposed strict law upon all classes of Portuguese society, along with a widespread review of the tax system. These reforms gained him enemies in the upper classes. Lisbon was struck by a major earthquake on November 1st 1755 , magnitude estimated to have been between 7.7–9.0, with casualties ranging from 12,000 to 50,000. Following
15004-441: Was banished to his estate at Pombal , where he died in 1782. Historians argue that Pombal's "enlightenment," while far-reaching, was primarily a mechanism for enhancing autocracy at the expense of individual liberty and especially an apparatus for crushing opposition, suppressing criticism, and furthering colonial exploitation and consolidating personal control, and profit. In 1807 Portugal refused Napoleon 's demand to accede to
15128-586: Was elected leader in 718 by many of the ousted Visigoth nobles. Pelagius called for the remnants of the Christian Visigothic armies to rebel against the Moors and regroup in the unconquered northern Asturian highlands, known today as the Cantabrian Mountains , in north-west Spain. After defeating the Moors in the Battle of Covadonga in 722, Pelagius was proclaimed king, thus founding the Christian Kingdom of Asturias and starting
15252-649: Was invaded from the South and became part of al-Andalus between 726 and 1249, following the Umayyad Caliphate conquest of the Iberian Peninsula . This rule lasted decades in the North, up to five centuries in the South. After defeating the Visigoths in a few months, the Umayyad Caliphate started expanding rapidly in the peninsula. Beginning in 726, the land that is now Portugal became part of
15376-504: Was proclaimed King of Portugal by his soldiers. This is traditionally taken as the occasion when the County of Portugal became the independent Kingdom of Portugal and, in 1129, the capital city was transferred from Guimarães to Coimbra. Afonso was recognized as the first king of Portugal in 1143 by King Alfonso VII of León , and in 1179 by Pope Alexander III as Afonso I of Portugal. Afonso Henriques and his successors, aided by military monastic orders , continued pushing southwards against
