Abraham Ortelius's 1570 world map, the world's first modern atlas.
Geographical exploration, sometimes considered the default meaning for the more general term exploration, refers to the practice of discovering remote lands and regions of the planet Earth.[1] It is studied by geographers and historians.[citation needed]
Two major eras of exploration occurred in human history: one of convergence, and one of divergence.[clarification needed] The first, covering most of Homo sapiens history, saw humans moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation.[2] Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas.[1] For the most part, these cultures were ignorant of each other's existence.[2] The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence.[2]
Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers of exploration was Ptolemy in the 2nd century AD.[clarification needed] Between the 5th century and 15th century AD, most exploration was done by Chinese and Arab explorers. This was followed by the Age of Discovery after European scholars rediscovered the works of early Latin and Greek geographers. While the Age of Discovery was partly driven by European land routes becoming unsafe,[3] and a desire for conquest, the 17th century saw exploration driven by nobler motives, including scientific discovery and the expansion of knowledge about the world.[1] This broader knowledge of the world's geography meant that people were able to make world maps, depicting all land known. The first modern atlas was the Theatrum Orbis Terrarum, published by Abraham Ortelius, which included a world map that depicted all of Earth's continents.[4]:32
Exploration is the process of exploring, which has been defined as:[5]
To examine or investigate something systematically.
To travel somewhere in search of discovery.
To examine diagnostically.
To (seek) experience first hand.
To wander without any particular aim or purpose.
Notable historical periods of human exploration
Evolution of Western knowledge of the world
Phoenician galley sailings
The Phoenicians (1550 BCE–300 BCE) traded throughout the Mediterranean Sea and Asia Minor though many of their routes are still unknown today. The presence of tin in some Phoenician artifacts suggests that they may have traveled to Britain. According to Virgil's Aeneid and other ancient sources, the legendary Queen Dido was a Phoenician from Tyre who sailed to North Africa and founded the city of Carthage.
All these expeditions were supported by legionaries and had mainly a commercial purpose. Only the one conducted by emperor Nero seemed to be a preparative for the conquest of Ethiopia or Nubia; in 62 AD, two legionaries explored the sources of the Nile.[6]
One of the main objectives of the explorations was to locate and obtain gold, using camels to transport it overland back to Roman provinces on the Mediterranean coast.[7]
With the acquisition of Ptolemaic Egypt, the Romans begin trading with India. The Romans now have a direct connection to the spice trade, which the Egyptians had established beginning in 118 BC.
A Roman diplomat or merchant lands in northern Vietnam and visits Nanjing, China and the court of Sun Quan, ruler of Eastern Wu.
Chinese exploration of Central Asia
During the 2nd century BC, the Han dynasty explored much of the Eastern Northern Hemisphere. Starting in 139 BC, the Han diplomat Zhang Qian traveled west in an unsuccessful attempt to secure an alliance with the Da Yuezhi against the Xiongnu (the Yuezhi had been evicted from Gansu by the Xiongnu in 177 BC); however, Zhang's travels discovered entire countries which the Chinese were unaware of, including the remnants of the conquests of Alexander the Great (r. 336–323 BC).[8] When Zhang returned to China in 125 BC, he reported on his visits to Dayuan (Fergana), Kangju (Sogdia), and Daxia (Bactria, formerly the Greco-Bactrian Kingdom which had just been subjugated by the Da Yuezhi).[9] Zhang described Dayuan and Daxia as agricultural and urban countries like China, and although he did not venture there, described Shendu (the Indus River valley of Northwestern India) and Anxi (Parthian territories) further west.[10]
Viking Age
Viking settlements and voyages
From about 800 AD to 1040 AD, the Vikings explored Iceland and much of the Western Northern Hemisphere via rivers and oceans. For example, it is known that the NorwegianViking explorer, Erik the Red (950–1003), sailed to and settled in Greenland after being expelled from Iceland, while his son, the Icelandic explorer Leif Erikson (980–1020), reached Newfoundland and the nearby North American coast, and is believed to be the first European to land in North America.
Polynesians were a maritime people, who populated and explored the central and south Pacific for around 5,000 years, up to about 1280 when they discovered New Zealand. The key invention to their exploration was the outrigger canoe, which provided a swift and stable platform for carrying goods and people. Based on limited evidence, it is thought that the voyage to New Zealand was deliberate. It is unknown if one or more boats went to New Zealand, or the type of boat, or the names of those who migrated. 2011 studies at Wairau Bar in New Zealand show a high probability that one origin was Ruahine Island in the Society Islands. Polynesians may have used the prevailing north easterly trade winds to reach New Zealand in about three weeks. The Cook Islands are in direct line along the migration path and may have been an intermediate stopping point. There are cultural and language similarities between Cook Islanders and New Zealand Māori. Early Māori had different legends of their origins, but the stories were misunderstood and reinterpreted in confused written accounts by early European historians in New Zealand trying to present a coherent pattern of Māori settlement in New Zealand.
Mathematical modelling based on DNA genome studies, using state of the art techniques, have shown that a large number of Polynesian migrants (100–200), including women, arrived in New Zealand around the same time, in about 1280. Otago University studies have tried to link distinctive DNA teeth patterns, which show special dietary influence, with places in or nearby the Society Islands.[11]
The Age of Discovery, also known as the Age of Exploration, is one of the most important periods of geographical exploration in human history. It started in the early 15th century and lasted until the 17th century. In that period, Europeans discovered and/or explored vast areas of the Americas, Africa, Asia, and Oceania. Portugal and Spain dominated the first stages of exploration, while other European nations followed, such as England, France, and the Netherlands.
Important explorations during this period went to a number of continents and regions around the globe. In Africa, important explorers of this period include Diogo Cão (1452–1486), who discovered and ascended the Congo River and reached the coasts of present-day Angola and Namibia; and Bartolomeu Dias (1450–1500), the first European to reach the Cape of Good Hope and other parts of the South African coast.
Explorers of routes from Europe towards Asia, the Indian Ocean, and the Pacific Ocean, include Vasco da Gama (1460–1524), a navigator who made the first trip from Europe to India and back by the Cape of Good Hope, discovering the ocean route to the East; Pedro Álvares Cabral (1467/1468–1520), who, following the path of Vasco da Gama, claimed Brazil and led the first expedition that linked Europe, Africa, America, and Asia; Diogo Dias, who discovered the eastern coast of Madagascar and rounded the corner of Africa; explorers such as Diogo Fernandes Pereira and Pedro Mascarenhas (1470–1555), among others, who discovered and mapped the Mascarene Islands and other archipelagos.
António de Abreu (1480–1514) and Francisco Serrão (14??–1521) led the first direct European fleet into the Pacific Ocean (on its western edges) and through the Sunda Islands, reaching the Moluccas. Andrés de Urdaneta (1498–1568) discovered the maritime route from Asia to the Americas.
Explorations of the Americas began with the initial discovery of America by Christopher Columbus (1451–1506), who led a Castilian (Spanish) expedition across the Atlantic, discovering America. After the discovery of America by Columbus, a number of important expeditions were sent out to explore the Western Hemisphere. This included Juan Ponce de León (1474–1521), who discovered and mapped the coast of Florida; Vasco Núñez de Balboa (1475–1519), who was the first European to view the Pacific Ocean from American shores (after crossing the Isthmus of Panama) confirming that America was a separate continent from Asia; Aleixo Garcia (14??–1527), who explored the territories of present-day southern Brazil, Paraguay and Bolivia, crossing the Chaco and reaching the Andes (near Sucre).
Long after the Age of Discovery, other explorers "completed" the world map, such as various Russian explorers, reaching the Siberian Pacific coast and the Bering Strait, at the extreme edge of Asia and Alaska (North America); Vitus Bering (1681–1741) who in the service of the Russian Navy, explored the Bering Strait, the Bering Sea, the North American coast of Alaska, and some other northern areas of the Pacific Ocean; and James Cook, who explored the east coast of Australia, the Hawaiian Islands, and circumnavigated Antarctica.
There were still significant explorations which occurred well into the late modern period. This includes the Lewis and Clark Expedition (1804–1806), an overland expedition dispatched by President Thomas Jefferson to explore the newly acquired Louisiana Purchase and to find an interior aquatic route to the Pacific Ocean, along with other objectives to examine the flora and fauna of the continent. In 1818, the British researcher John Ross was the first to find that the deep sea is inhabited by life when catching jellyfish and worms in about 2,000m (6,562ft) depth with a special device.[clarification needed] The United States Exploring Expedition (1838–1842) was an expedition sent by President Andrew Jackson, in order to survey the Pacific Ocean and surrounding lands.
The extreme conditions in the deep sea require elaborate methods and technologies to endure them. In the 20th century, deep-sea exploration advanced considerably through a series of technological inventions, ranging from the sonar system, which can detect the presence of solid objects underwater through the use of reflected sound, to manned deep-diving submersibles. In 1960, Jacques Piccard and United States Navy Lieutenant Donald Walsh descended in the bathyscapheTrieste into the deepest part of the world's oceans, the Mariana Trench.[12] In 2018, DSV Limiting Factor, piloted by Victor Vescovo, completed the first mission to the deepest point of the Atlantic Ocean, diving 8,375m (27,477ft) below the ocean surface to the base of the Puerto Rico Trench.[13] With the advent of satellite imagery and aviation, broad scale exploration of the surface of Earth has largely ceased, however the culture of many disconnected tribes still remain undocumented and left to be explored, and the details of more inaccessible ecosystems remains undescribed. Urban exploration is the exploration of manmade structures, usually abandoned ruins or hidden components of the manmade environment.
Space exploration started in the 20th century with the invention of exo-atmospheric rockets. This has given humans the opportunity to travel to the Moon, and to send robotic explorers to other planets and far beyond.
Both of the Voyager probes have left the Solar System, bearing imprinted gold discs with multiple data types.
The scope of underwater exploration includes the distribution and variety of marine and aquatic life, measurement of the geographical distribution of the chemical and physical properties, including movement of the water, and the geophysical, geological and topographical features of the Earth's crust where it is covered by water.[14]
Systematic, targeted exploration is the most effective method to increase understanding of the ocean and other underwater regions, so they can be effectively managed, conserved, regulated, and their resources discovered, accessed, and used. The ocean covers approximately 70% of Earth’s surface and has a critical role in supporting life on the planet but knowledge and understanding of the ocean remains limited due to difficulty and cost of access.[15]
The distinction between exploration, survey, and other research is somewhat blurred, and one way of looking at it is to consider the baseline surveys and research as exploration, as previously unknown information is gathered. Updating and refining the data is less exploratory in nature, but may still be exploration for the people involved, in the sense that the experience is new to them.
Status
According to NOAA, as of January 2023: "More than eighty percent of our ocean is unmapped, unobserved, and unexplored." Less than 10% of the ocean, including about 35% of the ocean and coastal waters of the United States, have been mapped in any detail using sonar technology.[16] According to GEBCO 2019 data, less than 18% of the deep ocean bed has been mapped using direct measurement and about 50% of coastal waters were not yet surveyed.[17]
Most of the data used to create global seabed maps are approximate depths derived from satellite gravity measurements and sea surface heights which are affected by the shape and mass distribution of the seabed. This method of approximation only provides low resolution information on large topographical features, and can miss significant features.[18]
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
The history of the Kingdom of Portugal from the Illustrious Generation of the early 15th century to the fall of the House of Aviz in the late 16th century has been named the "Portuguese golden age" and the "Portuguese Renaissance". During this period, Portugal was the first European power to begin building a colonial empire as during the Age of Exploration Portuguese sailors and explorers discovered an eastern route to India as well as several Atlantic archipelagos and colonized the African coast and Brazil. They also explored the Indian Ocean and established trading routes throughout most of southern Asia, sending the first direct European maritime trade and diplomatic missions to Ming China and to Japan, at the same time installing trading posts and the most important colony: Portuguese Macau. The Portuguese Renaissance produced a plethora of poets, historians, critics, theologians, and moralists. The Cancioneiro Geral by Garcia de Resende is taken to mark the transition from Old Portuguese to the modern Portuguese language.
Conquistadors or conquistadores is the term used to refer to Spanish and Portuguese soldiers and explorers who carried out the conquests and explorations of the Age of Discovery. Conquistadors sailed beyond the Iberian Peninsula to the Americas, Oceania, Africa and Asia, establishing new colonies and trade routes. They brought much of the "New World" under the dominion of Spain and Portugal.
The spice trade involved historical civilizations in Asia, Northeast Africa and Europe. Spices, such as cinnamon, cassia, cardamom, ginger, pepper, nutmeg, star anise, clove, and turmeric, were known and used in antiquity and traded in the Eastern World. These spices found their way into the Near East before the beginning of the Christian era, with fantastic tales hiding their true sources.
The Age of Discovery, also known as the Age of Exploration, was part of the early modern period and largely overlapped with the Age of Sail. It was a period from approximately the late 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe. The Age of Discovery was a transformative period in world history when previously isolated parts of the world became connected to form the world-system and laid the groundwork for globalization. The extensive overseas exploration, particularly the opening of maritime routes to the Indies and the European colonization of the Americas by the Spanish and Portuguese, later joined by the English, French and Dutch, spurred in the International global trade. The interconnected global economy of the 21st century has its origins in the expansion of trade networks during this era.
The human history of the west coast of North America is believed to stretch back to the arrival of the earliest people over the Bering Strait, or alternately along the ice free coastal islands of British Columbia (See, through the development of significant pre-Columbian cultures and population densities, to the arrival of the European explorers and colonizers. The west coast of North America today is home to some of the largest and most important companies in the world, as well as being a center of world culture.
The geography of North Africa has been reasonably well known among Europeans since classical antiquity in Greco-Roman geography. Northwest Africa was known as either Libya or Africa, while Egypt was considered part of Asia.
Ocean exploration is a part of oceanography describing the exploration of ocean surfaces. Notable explorations were undertaken by the Greeks, the Romans, the Polynesians, the Phoenicians, Phytheas, Herodotus, the Vikings, the Portuguese and Muslims. Scientific investigations began with early scientists such as James Cook, Charles Darwin, and Edmund Halley. Ocean exploration itself coincided with the developments in shipbuilding, diving, navigation, depth, measurement, exploration, and cartography.
Juan Fernández was a Spanish explorer and navigator in the Pacific regions of the Viceroyalty of Peru and Captaincy General of Chile west of colonial South America. He is best known for the discovery of a fast maritime route from Callao (Peru) to Valparaíso (Chile) as well as for the discovery of the Juan Fernández Islands off the coast of Chile.
This is a chronology of the early European exploration of Asia.
Portuguese maritime exploration resulted in the numerous territories and maritime routes recorded by the Portuguese as a result of their intensive maritime journeys during the 15th and 16th centuries. Portuguese sailors were at the vanguard of European exploration, chronicling and mapping the coasts of Africa and Asia, then known as the East Indies, and Canada and Brazil, in what came to be known as the Age of Discovery.
The exploration of North America by European sailors and geographers was an effort by major European powers to map and explore the continent with the goal of economic, religious and military expansion. The combative and rapid nature of this exploration is the result of a series of countering actions by neighboring European nations to ensure no single country had garnered enough wealth and power from the Americas to militarily tip the scales over on the European continent. It spanned the late 15th to early 17th centuries, and consisted primarily of expeditions funded by Spain, England, France, and Portugal. See also the European colonization of the Americas.
Major explorations of Earth continued after the Age of Discovery. By the early seventeenth century, vessels were sufficiently well built and their navigators competent enough to travel to virtually anywhere on the planet by sea. In the 17th century, Dutch explorers such as Willem Jansz and Abel Tasman explored the coasts of Australia. Spanish expeditions from Peru explored the South Pacific and discovered archipelagos such as Vanuatu and the Pitcairn Islands. Luis Vaez de Torres chartered the coasts of New Guinea and the Solomon Islands, and discovered the strait that bears his name. European naval exploration mapped the western and northern coasts of Australia, but the east coast had to wait for over a century. Eighteenth-century British explorer James Cook mapped much of Polynesia and traveled as far north as Alaska and as far south as the Antarctic Circle. In the later 18th century, the Pacific became a focus of renewed interest, with Spanish expeditions, followed by Northern European ones, reaching the coasts of northern British Columbia and Alaska.
Arctic exploration is the physical exploration of the Arctic region of the Earth. It refers to the historical period during which mankind has explored the region north of the Arctic Circle. Historical records suggest that humankind have explored the northern extremes since 325 BC, when the ancient Greek sailor Pytheas reached a frozen sea while attempting to find a source of the metal tin. Dangerous oceans and poor weather conditions often fetter explorers attempting to reach polar regions, and journeying through these perils by sight, boat, and foot has proven difficult.
This timeline of European exploration lists major geographic discoveries and other firsts credited to or involving Europeans during the Age of Discovery and the following centuries, between the years AD 1418 and 1957.
The era of European and American voyages of scientific exploration followed the Age of Discovery and were inspired by a new confidence in science and reason that arose in the Age of Enlightenment. Maritime expeditions in the Age of Discovery were a means of expanding colonial empires, establishing new trade routes and extending diplomatic and trade relations to new territories, but with the Enlightenment scientific curiosity became a new motive for exploration to add to the commercial and political ambitions of the past. See also List of Arctic expeditions and List of Antarctic expeditions.
Early Polynesian explorers reached nearly all Pacific islands by 1200 CE, followed by Asian navigation in Southeast Asia and the West Pacific. During the Middle Ages, Muslim traders linked the Middle East and East Africa to the Asian Pacific coasts, reaching southern China and much of the Malay Archipelago. Direct European contact with the Pacific began in 1512, with the Portuguese encountering its western edges, soon followed by the Spanish arriving from the American coast.
This is a timeline of events in maritime history.
The history of exploration by citizens or subjects of the Russian Federation, the Soviet Union, the Russian Empire, the Tsardom of Russia and other Russian predecessor states forms a significant part of the history of Russia as well as the history of the world. At 17,075,400 square kilometres (6,592,850 sq mi), Russia is the largest country in the world, covering more than a ninth of Earth's landmass. In the times of the Soviet Union and the Russian Empire, the country's share in the world's landmass reached 1/6. Most of these territories were first discovered by Russian explorers. Contiguous exploration in Eurasia and the building of overseas colonies in Russian America were some of the primary factors in Russian territorial expansion.
