paragraph_text: Namcha Barwa was located in 1912 by British surveyors but the area remained virtually unvisited until Chinese alpinists began attempting the peak in the 1980s.  Although they scouted multiple routes, they did not reach the summit. In 1990 a Chinese-Japanese expedition reconnoitered the peak.  Another joint expedition reached 7,460 metres (24,480 ft) in 1991 but lost member Hiroshi Onishi in an avalanche. The next year a third Chinese-Japanese expedition established six camps on the South Ridge over intermediate Nai Peng (7,043 metres or 23,107 feet) reaching the summit October 30.

paragraph_text: Global exploration started with the Portuguese discoveries of the Atlantic archipelagos of Madeira and the Azores, the coast of Africa, and the discovery of the sea route to India in 1498; and the Crown of Castile (Spain) the trans - Atlantic Voyages of Christopher Columbus to the Americas between 1492 and 1502 and the first circumnavigation of the globe in 1519 -- 1522. These discoveries led to numerous naval expeditions across the Atlantic, Indian and Pacific oceans, and land expeditions in the Americas, Asia, Africa and Australia that continued into the late 19th century, and ended with the exploration of the polar regions in the 20th century.

paragraph_text: Explorers flying the flag of Spain reached the New World beginning in 1492 with the discovery of America by Christopher Columbus. Spanish expeditions colonized and explored vast areas in North and South America following the grants of the Pope (contained in the 1493 papal bull Inter caetera) and rights contained in the 1494 Treaty of Tordesillas and 1529 Treaty of Zaragoza. These formal acts gave Spain the exclusive rights to colonize the entire Western Hemisphere (excluding eastern Brazil), including all of the west coast of North America. The first European expedition to actually reach the west coast was led by the Spaniard Vasco Núñez de Balboa, who reached the Pacific coast of Panama in 1513. In an act of enduring historical importance, Balboa claimed the Pacific Ocean for the Spanish Crown, as well as all adjoining land and islands. This act gave Spain exclusive sovereignty and navigation rights over the entire west coast of North America.

paragraph_text: The first country to attempt to circumnavigate Africa was Portugal, which had, since the early 15th century, begun to explore northern Africa under Henry the Navigator. Emboldened by these early successes and eyeing a lucrative monopoly on a possible sea route to the Indies the Portuguese first crossed the Cape of Good Hope in 1488 on an expedition led by Bartolomeu Dias. Just nine years later in 1497 on the orders of Manuel I of Portugal, four vessels under the command of navigator Vasco da Gama rounded the Cape of Good Hope, continuing to the eastern coast of Africa to Malindi to sail across the Indian Ocean to Calicut, on the Malabar Coast. in south India -- the capital of the local Zamorin rulers. The wealth of the Indies was now open for the Europeans to explore; the Portuguese Empire was the earliest European seaborne empire to grow from the spice trade.

paragraph_text: The Portuguese Vasco da Gama, accompanied by Nicolau Coelho and Bartolomeu Dias, is the first European to reach India by an all - sea route from Europe.

paragraph_text: Explorer James Clark Ross passed through what is now known as the Ross Sea and discovered Ross Island (both of which were named after him) in 1841. He sailed along a huge wall of ice that was later named the Ross Ice Shelf. Mount Erebus and Mount Terror are named after two ships from his expedition: HMS Erebus and Terror. Mercator Cooper landed in East Antarctica on 26 January 1853.During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton and three other members of his expedition made several firsts in December 1908 – February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.

paragraph_text: The "Havørn" Accident () was a controlled flight into terrain of a Junkers Ju 52 aircraft into the mountain Lihesten in Hyllestad, Norway on 16 June 1936 at 07:00. The aircraft, operated by Norwegian Air Lines, was en route from Bergen to Tromsø. The pilots were unaware that they were flying a parallel to the planned course, further east. The crew of four and three passengers were all killed in what was the first fatal aviation accident in Norway. The aircraft landed on a shelf on the mountain face. A first expedition found four bodies, but attempts to reach the shelf with the main part of the aircraft and three more bodies failed. A second party was sent out two days later, coordinated by Bernt Balchen and led by Boye Schlytter and Henning Tønsberg, saw the successful salvage of the remaining bodies.

While searching for a passage between the Gulf of Mexico and Asia, Álvarez de Pineda created the first map of the northern Gulf Coast. This map is the earliest recorded document of Texas history.

paragraph_text: The Red Sea is one of the saltiest bodies of water in the world, owing to high evaporation. Salinity ranges from between ~ 36 ‰ in the southern part because of the effect of the Gulf of Aden water and reaches 41 ‰ in the northern part, owing mainly to the Gulf of Suez water and the high evaporation. The average salinity is 40 ‰. (Average salinity for the world's seawater is ~ 35 ‰ on the Practical Salinity Scale, or PSU; that translates to 3.5% of actual dissolved salts.)

paragraph_text: Portuguese discoveries (Portuguese: Descobrimentos portugueses) are the numerous territories and maritime routes discovered by the Portuguese as a result of their intensive maritime exploration during the 15th and 16th centuries. Portuguese sailors were at the vanguard of European overseas exploration, discovering and mapping the coasts of Africa, Canada, Asia and Brazil, in what became known as the Age of Discovery. Methodical expeditions started in 1419 along West Africa's coast under the sponsorship of prince Henry the Navigator, with Bartolomeu Dias reaching the Cape of Good Hope and entering the Indian Ocean in 1488. Ten years later, in 1498, Vasco da Gama led the first fleet around Africa to India, arriving in Calicut and starting a maritime route from Portugal to India. Portuguese explorations then proceeded to southeast Asia, where they reached Japan in 1542, forty - four years after their first arrival in India. In 1500, the Portuguese nobleman Pedro Álvares Cabral became the first European to discover Brazil.

paragraph_text: The written history of the Cape Colony in what is now South Africa began when Portuguese navigator Bartolomeu Dias became the first modern European to round the Cape of Good Hope in 1488. In 1497, Vasco da Gama sailed along the whole coast of South Africa on his way to India, landed at St Helena Bay for 8 days, and made a detailed description of the area. The Portuguese, attracted by the riches of Asia, made no permanent settlement at the Cape Colony. However, the Dutch East India Company (VOC) settled the area as a location where vessels could restock water and provisions.

paragraph_text: The first expedition to reach the geographic South Pole was led by the Norwegian explorer Roald Amundsen. He and four others arrived at the pole on 14 December 1911, five weeks ahead of a British party led by Robert Falcon Scott as part of the Terra Nova Expedition. Amundsen and his team returned safely to their base, and later learned that Scott and his four companions had died on their return journey.

paragraph_text: European colonization began in 1492, when a Spanish expedition headed by the Genoese explorer Christopher Columbus sailed west to find a new trade route to the Far East but inadvertently landed in what came to be known to Europeans as the ``New World ''. Running aground on the northern part of Hispaniola on 5 December 1492, which the Taino people had inhabited since the 7th century, the site became the first European settlement in the Americas. European conquest, large - scale exploration and colonization soon followed. Columbus's first two voyages (1492 -- 93) reached the Bahamas and various Caribbean islands, including Hispaniola, Puerto Rico and Cuba. In 1498, sailing from Bristol on behalf of England, John Cabot landed on the North American coast, and a year later, Columbus's third voyage reached the South American coast. As the sponsor of Christopher Columbus's voyages, Spain was the first European power to settle and colonize the largest areas, from North America and the Caribbean to the southern tip of South America.

paragraph_text: The voyage was commissioned by King George III and commanded by Lieutenant James Cook, a junior naval officer with good skills in cartography and mathematics. Departing from Plymouth - Dock (Devonport) in August 1768, the expedition crossed the Atlantic, rounded Cape Horn and reached Tahiti in time to observe the transit of Venus. Cook then set sail into the largely uncharted ocean to the south, stopping at the Pacific islands of Huahine, Borabora and Raiatea to claim them for Great Britain, and unsuccessfully attempting to land at Rurutu. In September 1769 the expedition reached New Zealand, being the second Europeans to visit there, following the first European discovery by Abel Tasman 127 years earlier. Cook and his crew spent the following six months charting the New Zealand coast, before resuming their voyage westward across open sea. In April 1770 they became the first Europeans to reach the east coast of Australia, making landfall at Point Hicks, and then proceeding to Botany Bay.

paragraph_text: Garnet Point () is a rocky coastal point consisting of garnet gneiss, located at the west side of the entrance to Watt Bay, in the George V Coast area of Antarctica. Garnet Point was discovered by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, and named by that expedition's geological party led by Frank L. Stillwell.

paragraph_text: The Terra Nova Expedition, officially the British Antarctic Expedition, was an expedition to Antarctica which took place between 1910 and 1913. It was led by Robert Falcon Scott and had various scientific and geographical objectives. Scott wished to continue the scientific work that he had begun when leading the Discovery Expedition to the Antarctic in 1901–1904. He also wanted to be the first to reach the geographic South Pole. He and four companions attained the pole on 17 January 1912, where they found that the Norwegian team led by Roald Amundsen had preceded them by 34 days. Scott's entire party died on the return journey from the pole; some of their bodies, journals, and photographs were found by a search party eight months later.
