Most of the meteorology is incorrect, but is accepted as correct until the 15 th century Meteorologia 330 B.C.E.Greek geographer and explorer Pytheas proposes that tides are caused by the Moon. His observation of spring tides occurring during a new or full Moon led him to conclude that the Moon was connected to the height of the tides 240 B.C.EGreek astronomer Eratosthenes of Cyrene becomes the first to accurately measure the circumference of the Earth A.D. 132 Chinese astronomer royal, Zhang Heng invents the first seismograph. A case of 8 bronze dragons’ heads around the top- each dragon held a bronze ball in its mouth. When an earthquake began, the ball sitting in the opposite direction of the earthquake source would fall into the mouth of a bronze toad at the bottom of the case, making a loud ring. In this way the direction of the earthquake could be determined 140 Greek astronomer Claudius Ptolemy defines the universe mathematically using data collected by the Babylonians to create mathematical models for the positions of the planets and predictions of future positions.

18. Ocean Exploration Timeline

19. History of Ocean Exploration- 4000 B.C. Egyptians develop sailing vessels. These were probably used only in the eastern Mediterranean near the mouth of the Nile River. 600 B.C. Phoenicians develop sea routes around the entire Mediterranean and into the Red Sea and the Indian Ocean. They made it all the way around Africa near 590 B.C. Phoenicians also reached England by sailing along the western European coast. They were trying to find sources of tin to use in producing bronze. Although they understood celestial navigation, they probably stayed within sight of land whenever possible. 500-200 B.C. Greeks develop trade routes throughout the Mediterranean. They used the length of the day (corrected for the time of the year) to estimate latitude.

20. History of Ocean Exploration 2 450 B.C. Herodotus (Greek) publishes an accurate map of the Mediterranean region (Fig. 1-2 in your book). 325 B.C. Pytheas, a Greek astronomer and geographer, sailed north out of the Mediterranean, reaching England and possibly even Iceland and Norway. He also developed the use of sightings on the North Star to determine latitude and figured out that tides were related to phases of the moon. 200 B.C. Eratosthenes, a Greek determines the circumference of the Earth using angles of shadows in Syene and Alexandria. His estimate was about 40,000 k.m.; the real value is 40,032 k.m.

21. History of Ocean Exploration 3 150 A.D. Ptolemy produces a map of the Roman world, including lines of latitude and longitude, the continents of Asia, Europe, and Africa and the surrounding oceans. 600 A.D. Europeans, having lost access to Greek and Roman texts, have forgotten much of what they knew about the world and ocean navigation. 900 -1430 A.D. Vikings explore and colonize Iceland, Greenland, Newfoundland (Canada) using the North Star to determine latitude.

22. History of Ocean Exploration (4) 1405-1433 A.D. Chinese send seven voyages in 317 huge technologically advanced ships with 37,000 crew. These missions were not for conquest, religion, or trade, but instead were designed to extend Chinese influence and impress their neighbor states. Economic pressures ended the expensive voyages after a short time, and China isolated itself. 1410 A.D. Ptolemy's map of the oceans is published once more after European crusades capture Roman libraries from Arab peoples. 1498 A.D. Vasco da Gama sails around Africa from Portugal; reaches India to establish trade routes 1519-1522 A.D. Ferdinand Magellan's ships circumnavigate the world (although Magellan died partway there).

23. History of Ocean Exploration 5 1768-1780 A.D. James Cook Great Britain explores the southern parts of the oceans looking for the southern continent (Antarctica). He was the first to use a chronometer (very accurate clock) to determine longitude. 1831-1836 A.D. Charles Darwin (Great Britain ) sails on the Beagle, exploring the Galapagos and many other areas. It is this work which led him to develop the concept of natural selection and evolution 1872-1876 A.D. The H.M.S. Challenger (Great Britain ) traveled around the world on a purely scientific mission, taking sediment samples, water samples, soundings, and collecting many biological specimens. 1925-1927 A.D. The Meteor, a German vessel, sails around the Atlantic, taking detailed echo sounding measurements that reveal much new information about the structure and shape of the ocean floor. 1968 A.D.-present International scientific deep-sea drilling programs (DSDP, ODP, and IODP) run drilling cruises throughout the world's oceans, creating a huge repository of sediment cores, measurements, and information.

Voyage of the Beagle - Darwin The Voyage of the Beagle is a title commonly given to the book written by Charles Darwin and published in 1839 as his Journal and Remarks, bringing him considerable fame and respect. The title refers to the second survey expedition of the ship HMS Beagle, which set sail from Plymouth Sound on 27 December 1831 under the command of captain Robert FitzRoy

HMS Challenger –What we get The following slide shows the idea of mermaids helping with the dredging. “After the dredge was put over and lowered to the bottom, where it was allowed to remain for some hours, the vessel slowly drifted onward. On hauling, in it was found turned upside- down and in a lovely tangle. ”

35. Oceanographic Expeditions “For the oceanographers who were iron men sailing in wooden ships” This is a list and brief synopsis of notable expeditions that have in some way benefited the field of oceanography. It covers the years 1657 to 1933 from Seas, Maps, and Men: An Atlas-History of Man's Exploration of the Oceans (1962), a book edited by G. E. R. Deacon Edmund Halley (1657-1742) A British astronomer, Halley (of comet fame) made probably the first primarily scientific voyage--to study the variation of the magnetic compass--sailing as far as 52 deg. S in the Atlantic Ocean in 1698-1700. On a previous expedition to St. Helena, he made an important contribution to knowledge of the trade winds. He realized more than anyone the value of Newton's Principia and arranged for it to be printed at his own expense. James Cook (1728-1779) On his three great voyages between 1768 and 1780, Cook carried naturalists in his ships and made careful observations of winds and currents. During the second voyage the Forster brothers measured subsurface temperatures and found a warm deep layer below the Antarctic surface water. Francois Peron (1775-1810) A French naturalist and physicist, Peron accompanied a French circumnavigation of the globe in 1800-1804. He was able to make only a few rather uncertain deep temperature measurements, but was much impressed by the importance of oceanic research and maintained that it had received too little attention.

36. Expeditions Ivan F. Kruzenstein (1770-1846) He commanded a Russian circumnavigation in 1803- 1806 and was accompanied by Dr. J. C. Horner and with him made a number of deep sea temperature measurements in the tropical Pacific and the Sea of Okhotsk. William Scoresby (1789-1857) An English whaler and scientist, Scoresby made many surface and deep observations in the seas around Spitsbergen and off the coast of Greenland between 1810 and 1822. Fabion G. von Bellingshausen (1779-1852) He circumnavigated the Antarctic continent in 1819-1821, much of the voyage being south of 60 deg. S. He was bitterly disappointed in having to sail without a naturalist. "In this way our hopes of making discoveries in the field of natural history were dashed to the ground," he wrote. Nevertheless, he made many valuable observations, and his artist Paul Mikhailov painted a fine series of pictures of marine animals

37. Expeditions Otto von Kotzebue (1787-1846) This Russian admiral made two circumnavigations in 1815-1818 and 1823-1826, primarily for scientific purposes. Many deep-sea temperature observations were made, and Emil von Lenz, physicist on the second voyage, recognized that a surface flow of water from low to high latitudes must be supplied by a flow from the poles at great depths. Jean S. C. Dumont d'Urville (1790-1842) A French admiral, he made three circumnavigations in 1822-1825, 1826-1829, and 1837-1840. He made many deep-sea temperature observations, but because of the effect of pressure on the thermometers he concluded that in the open oceans the temperature of the water below about 500 fathoms was uniform at nearly 4.4 deg. C. He wrongly concluded that somewhere between 40 deg. S and 60 deg. S, ocean water was at a uniform temperature of 4.4 deg. C from the surface to the bottom. Sir James Clark Ross (1800-1862) He made the first extensive series of deep sea soundings during his voyage to the Southern Seas in 1839-1843 in H. M. S. Erebus and Terror. He made comprehensive studies of the Earth's magnetism, many deep-sea temperature measurements and extensive biological collections. Dr. J. D. Hooker, who went on the voyage as surgeon-naturalist, published his well-known Botany of the Antarctic, voyage of the Erebus and Terror. Ross also studied the effect of variations of atmospheric pressure on sea level. He had the same ideas as Dumont d'Urville about temperature of the deep water. Dredgings were made at depths down to 400 fathoms but the collections were subsequently neglected and lost to science.Dumont d'Urville

38. Expeditions Charles Wilkes (1798-1877) He commanded six ships taking part in the U.S. expedition of 1838-1842. Although the scientific staff, under the direction of the famous naturalist J. D. Dana, did not go south of Sydney, Australia, extensive natural history collections were made. Scientifically the expedition is best known for Dana's description of Crustacea. What must have been an enormous collection of fishes was never properly reported on. Robert Fitzroy (1805-1865) This British admiral commanded the Beagle during her famous voyages of 1826-1836. Charles Darwin, who sailed in her from 1831-1836, added much to our knowledge of natural history, especially on the structure and origin of coral reefs and islands. Only two sets of temperature observations were made. Matthew F. Maury (1806-1873) An officer in the United States Navy, he sailed around the world and his sea experience taught him the critical need to increase the efficiency of shipping through better navigation and safety at sea. He was successful in convincing the world of the value of more systematic study and charting of winds and currents. He also produced the first bathymetric chart of the North Atlantic Current.

39. Expeditions Edward Forbes (1815-1854) He studied the fauna of the Aegean Sea and did much to stimulate interest in marine biology, partly, perhaps, by promoting an active study of depths greater than 300 fathoms, below which he believed that animal life ceased to exist. William B. Carpenter (1813-1885) Sir Charles Wyville Thomson (1830-1882) Gwyn Jeffreys (1809-1885) They made dredging expeditions in H.M.S. Lightning, Porcupine, and Shearwater in the eastern North Atlantic and Mediterranean Sea. They found many new species of animals and made enough temperature observations to show that there was an active circulation of the water below the surface. They dredged at depths down to 2000 fathoms. H. M. S. Challenger (1872-1876) This research ship carried five scientists, under the direction of Wyville Thomson, and made extensive biological, chemical, geological and physical observations, mainly in the Atlantic and Pacific Oceans and across the Indian Ocean south of 40 deg. S. The extensive biological collections, together with soundings, bottom samples, and chemical and physical observations, presented the first broad view of the character of the oceans.
