As a sailor, Maury noted numerous lessons that ship masters had learned about the effects of adverse winds and drift currents on the path of a ship. The captains recorded the lessons faithfully in their logbooks, which were then forgotten. At the Observatory, Maury uncovered an enormous collection of thousands of old ships' logs and charts in storage in trunks dating back to

The two remained lifelong friends. Other religious friends of Maury included James Hervey Otey , his former teacher who, before 1857, worked with Bishop Leonidas Polk on the construction of
750-608: A few years, nations owning three-fourths of the shipping of the world were sending their oceanographic observations to Maury at the Naval Observatory, where the information was evaluated and the results were given worldwide distribution. As its representative at the conference, the United States sent Maury. As a result of the Brussels Conference, many nations, including many traditional enemies, agreed to cooperate in sharing land and sea weather data using uniform standards. It
875-468: A land system of weather observations. Maury became convinced that adequate scientific knowledge of the sea could be obtained only through international cooperation. He proposed that the United States invite the maritime nations of the world to a conference to establish a "universal system" of meteorology, and he was the leading spirit of a pioneer scientific conference when it met in Brussels in 1853.

Following the war, Maury was eventually pardoned; he accepted a teaching position at the Virginia Military Institute in Lexington, Virginia . He died at the institute in 1873 after he had completed an exhausting state-to-state lecture tour on national and international weather forecasting on land. He had also completed his book, Geological Survey of Virginia , and
1750-608: A voyage around the Cape of Good Hope in 1777, he mapped "the banks and currents at the Lagullas " . He was also the first to understand the nature of the intermittent current near the Isles of Scilly , (now known as Rennell's Current). The tides and currents of the ocean are distinct. Tides are the rise and fall of sea levels created by the combination of the gravitational forces of the Moon along with

Affected planktonic organisms will include pteropods , coccolithophorids and foraminifera , all important in the food chain . In tropical regions, corals are likely to be severely affected as they become less able to build their calcium carbonate skeletons, in turn adversely impacting other reef dwellers. The current rate of ocean chemistry change seems to be unprecedented in Earth's geological history, making it unclear how well marine ecosystems will adapt to

Challenger , leased from the Royal Navy, was modified for scientific work and equipped with separate laboratories for natural history and chemistry . Under the scientific supervision of Thomson, Challenger travelled nearly 70,000 nautical miles (130,000 km) surveying and exploring. On her journey circumnavigating the globe, 492 deep sea soundings, 133 bottom dredges, 151 open water trawls and 263 serial water temperature observations were taken. Around 4,700 new species of marine life were discovered. The result
2875-1098: The American Civil War , Maury joined the Confederacy. Upon his resignation from the U.S. Navy, the Virginia governor appointed Maury commander of the Virginia Navy. When this was consolidated into the Confederate Navy, Maury was made a Commander in the Confederate States Navy and appointed as chief of the Naval Bureau of Coast, Harbor, and River Defense. In this role, Maury helped develop the first electrically controlled naval mine, which caused havoc for U.S. shipping. He'd had experience with transatlantic cable and electricity flowing through wires underwater when working with Cyrus West Field and Samuel Finley Breese Morse . The naval mines, called torpedoes at that time, were similar to present-day contact mines and were said by

Lee in Lexington, where Lee was president of Washington College. Maury served as a pallbearer for Lee. He also gave talks in Europe about cooperation on a weather bureau for land, just as he had charted the winds and predicted storms at sea many years before. He gave speeches until his last days when he collapsed while giving one. He went home after he recovered and told his wife Ann Hull Herndon-Maury, "I have come home to die." He died at home in Lexington at 12:40 pm on Saturday, February 1, 1873. He

The secrecy involving the Portuguese navigations, with the death penalty for the leaking of maps and routes, concentrated all sensitive records in the Royal Archives, completely destroyed by the Lisbon earthquake of 1775 . However, the systematic nature of the Portuguese campaign, mapping
9375-531: The northern states of Mexico . Maury also advocated construction of a railroad across the Isthmus of Panama . For his scientific endeavors, Maury was elected to the American Philosophical Society in 1852. Maury also called for an international sea and land weather service. Having charted the seas and currents, he worked on charting land weather forecasting. Congress refused to appropriate funds for
9500-530: The ocean's physical attributes including temperature-salinity structure, mixing, surface waves , internal waves, surface tides , internal tides , and currents . The following are central topics investigated by physical oceanography. Since the early ocean expeditions in oceanography, a major interest was the study of ocean currents and temperature measurements. The tides , the Coriolis effect , changes in direction and strength of wind , salinity, and temperature are
9625-412: The oceans was primarily for cartography and mainly limited to its surfaces and of the animals that fishermen brought up in nets, though depth soundings by lead line were taken. The Portuguese campaign of Atlantic navigation is the earliest example of a systematic scientific large project, sustained over many decades, studying the currents and winds of the Atlantic. The work of Pedro Nunes (1502–1578)
9750-402: The pH (now below 8.1 ) through ocean acidification. The pH is expected to reach 7.7 by the year 2100. An important element for the skeletons of marine animals is calcium , but calcium carbonate becomes more soluble with pressure, so carbonate shells and skeletons dissolve below the carbonate compensation depth . Calcium carbonate becomes more soluble at lower pH, so ocean acidification
9875-488: The plan, Lee wrote Maury saying, "The thought of abandoning the country, and all that must be left in it, is abhorrent to my feelings, and I prefer to struggle for its restoration, and share its fate, rather than to give up all as lost." In the end, the plan did not attract the intended immigrants and Maximilian, facing increasing opposition in Mexico, ended it. Maury then returned to England in 1866 and found work there. In 1868 he
10000-690: The polar regions and Africa , so too did the mysteries of the unexplored oceans. The seminal event in the founding of the modern science of oceanography was the 1872–1876 Challenger expedition . As the first true oceanographic cruise, this expedition laid the groundwork for an entire academic and research discipline. In response to a recommendation from the Royal Society , the British Government announced in 1871 an expedition to explore world's oceans and conduct appropriate scientific investigation. Charles Wyville Thomson and Sir John Murray launched
10125-460: The proposals, and Maury's proposal received little or no support in the United States, especially in the South, which sought to perpetuate the institution and the riches made off the yoke of slavery. By 1855, the proposal had failed. Brazil authorized free navigation to all nations in the Amazon in 1866, only when it was at war against Paraguay, when free navigation in the area had become necessary. Maury
10250-466: The rest of her career. (Russell, 2000) Sverdrup, Johnson and Fleming published The Oceans in 1942, which was a major landmark. The Sea (in three volumes, covering physical oceanography, seawater and geology) edited by M.N. Hill was published in 1962, while Rhodes Fairbridge 's Encyclopedia of Oceanography was published in 1966. The Great Global Rift, running along the Mid Atlantic Ridge,
10375-513: The return route from the western coast of Africa (sequentially called 'volta de Guiné' and 'volta da Mina'); and the references to the Sargasso Sea (also called at the time 'Mar da Baga'), to the west of the Azores , in 1436, reveals the western extent of the return route. This is necessary, under sail, to make use of the southeasterly and northeasterly winds away from the western coast of Africa, up to
10500-495: The river highways of the Amazon valley". Brazil maintained legal enslavement but had prohibited the importation of newly enslaved people from Africa in 1850 under the pressure of the British. Maury proposed that moving people enslaved in the United States to Brazil would reduce or eliminate slavery over time in as many areas of the southern United States as possible and would end new enslavement for Brazil. Maury's primary concern, however,
10625-410: The route taken by Gama at the time he set sail). Furthermore, there were systematic expeditions pushing into the western Northern Atlantic (Teive, 1454; Vogado, 1462; Teles, 1474; Ulmo, 1486). The documents relating to the supplying of ships, and the ordering of sun declination tables for the southern Atlantic for as early as 1493–1496, all suggest a well-planned and systematic activity happening during
10750-555: The scientific community to assess the role of the oceanic processes in the global climate by the reconstruction of past climate at various intervals. Paleoceanographic research is also intimately tied to palaeoclimatology. The earliest international organizations of oceanography were founded at the turn of the 20th century, starting with the International Council for the Exploration of the Sea created in 1902, followed in 1919 by
10875-400: The shifting conditions of the near future. Of particular concern is the manner in which the combination of acidification with the expected additional stressors of higher ocean temperatures and lower oxygen levels will impact the seas. Geological oceanography is the study of the geology of the ocean floor including plate tectonics and paleoceanography . Physical oceanography studies
11000-505: The slave trade that accompanied his scientific achievements. Maury staunchly opposed secession, but in 1860, he wrote letters to the governors of New Jersey, Pennsylvania, Delaware, and Maryland urging them to stop the momentum toward war. When Virginia declared secession in April 1861, Maury nonetheless resigned his commission in the U.S. Navy, choosing to fight against the North. With the outbreak of
11125-413: The start of the U.S. Navy. He pored over the documents, collecting information on winds, calms, and currents for all seas in all seasons. His dream was to put that information in the hands of all captains. Maury's work on ocean currents and investigations of the whaling industry led him to suspect that a warm-water, ice-free northern passage existed between the Atlantic and Pacific. He thought he detected
11250-418: The study of marine meteorology, navigation , and charting prevailing winds and currents. His 1855 textbook Physical Geography of the Sea was one of the first comprehensive oceanography studies. Many nations sent oceanographic observations to Maury at the Naval Observatory, where he and his colleagues evaluated the information and distributed the results worldwide. Knowledge of the oceans remained confined to
11375-520: The submersible DSV Alvin . In the 1950s, Auguste Piccard invented the bathyscaphe and used the bathyscaphe Trieste to investigate the ocean's depths. The United States nuclear submarine Nautilus made the first journey under the ice to the North Pole in 1958. In 1962 the FLIP (Floating Instrument Platform), a 355-foot (108 m) spar buoy, was first deployed. In 1968, Tanya Atwater led
11500-400: The topmost few fathoms of the water and a small amount of the bottom, mainly in shallow areas. Almost nothing was known of the ocean depths. The British Royal Navy 's efforts to chart all of the world's coastlines in the mid-19th century reinforced the vague idea that most of the ocean was very deep, although little more was known. As exploration ignited both popular and scientific interest in
11625-522: The university president announced it would recommend to the JMU board of visitors to rename Maury Hall, along with Ashby Hall and Jackson Hall. Ships have been named in his honor, including various vessels named USS Maury ; USS Commodore Maury (SP-656), a patrol vessel and minesweeper of World War I; and a World War II Liberty Ship . Additionally, Tidewater Community College, based in Norfolk, Virginia , owns
11750-496: The vessel lost 36 members of her crew to the gold fever sweeping California at the time. Turning south, Vincennes cruised off South America until late 1851, closely monitoring the activities of revolutionaries ashore. She made a courtesy call to the Hawaiian Islands at the end of the year and proceeded thence to Puget Sound where she arrived on 2 February 1852. She anchored briefly there and returned via San Francisco and
11875-467: The visitors were treated with courtesy. However, Commodore Biddle's attempts to force the opening of feudal Japan to multinational trade were politely rebuffed, and the vessels weighed anchor on 29 July. Columbus returned to the United States by way of Cape Horn , but Vincennes remained on the China Station for another year before returning to New York on 1 April 1847. Here, she was decommissioned on
12000-489: The west coast of South America and in the South Pacific during the rest of the year, in late 1839 Vincennes arrived at Sydney, Australia , her base for a pioneering cruise to Antarctica . She unintentionally exposed the lack of defences and security at Sydney Harbour when she slipped unnoticed into Sydney Harbour on 30 November 1839 under the cover of darkness. Between mid-January and mid-February 1840, she operated along
12125-434: The world ocean through further scientific study enables better stewardship and sustainable utilization of Earth's resources. The Intergovernmental Oceanographic Commission reports that 1.7% of the total national research expenditure of its members is focused on ocean science. The study of oceanography is divided into these five branches: Biological oceanography investigates the ecology and biology of marine organisms in
12250-604: Was "work to be done by Africans with the American axe in his hand." In the 1850s, he studied a way to send Virginia's slaves to Brazil as a way to phase out slavery in the state gradually. Maury was aware of an 1853 survey of the Amazon region conducted by the Navy Lt. William Lewis Herndon. The 1853 expedition aimed to map the area for trade so that American traders could go "with their goods and chattels [including enslaved people] to settle and to trade goods from South American countries along
12375-823: Was a veteran of the Wilkes expedition. The squadron stood out of Norfolk on 11 June 1853, rounded the Cape of Good Hope , and charted numerous islands and shoals in the Indian Ocean before arriving in China in March 1854. Here Commodore Matthew Calbraith Perry relieved Ringgold for medical reasons and gave command of the expedition to Lt. John Rodgers . Vincennes sailed on to survey the Bonin and Ladrone Islands and returned to Hong Kong in February 1855. The expedition sailed again in March and surveyed
12500-623: Was accompanied by the ship-of-the-line Columbus , under the command of Captain Thomas Wyman ; and the two vessels formed a little squadron under the command of Commodore James Biddle , who carried a letter from Secretary of State John C. Calhoun to Caleb Cushing , American commissioner in China , authorizing Cushing to make the first official contact with the Japanese Government. The squadron sailed for Macau by way of Rio de Janeiro and
12625-466: Was adopted by navies and merchant marines worldwide and was used to develop charts for all the major trade routes. With the outbreak of the American Civil War , Maury, a Virginian , resigned his commission as a U.S. Navy commander and joined the Confederacy . He spent the war in the Southern United States , and Great Britain and France as a Confederate envoy. He helped the Confederacy acquire
12750-506: Was authorized by Congress on 3 March 1825. She was laid down at New York in 1825, launched on 27 April 1826, and commissioned on 27 August 1826, with Master Commandant William Compton Bolton in command. The ship set sail for the first time on 3 September 1826, from New York bound for the Pacific by way of Cape Horn . She cruised extensively in that ocean, visiting the Hawaiian Islands in 1829 and made her way to Macau by 1830, under Commander William B. Finch . Her return voyage
12875-674: Was built in 1882. In 1893, Fridtjof Nansen allowed his ship, Fram , to be frozen in the Arctic ice. This enabled him to obtain oceanographic, meteorological and astronomical data at a stationary spot over an extended period. In 1881 the geographer John Francon Williams published a seminal book, Geography of the Oceans . Between 1907 and 1911 Otto Krümmel published the Handbuch der Ozeanographie , which became influential in awakening public interest in oceanography. The four-month 1910 North Atlantic expedition headed by John Murray and Johan Hjort
13000-586: Was discovered by Maurice Ewing and Bruce Heezen in 1953 and mapped by Heezen and Marie Tharp using bathymetric data; in 1954 a mountain range under the Arctic Ocean was found by the Arctic Institute of the USSR. The theory of seafloor spreading was developed in 1960 by Harry Hammond Hess . The Ocean Drilling Program started in 1966. Deep-sea vents were discovered in 1977 by Jack Corliss and Robert Ballard in
13125-415: Was exhausted from traveling throughout the nation giving speeches promoting land meteorology. His eldest son, Major Richard Launcelot Maury, and son-in-law, Major Spottswood Wellford Corbin, attended him at the time. Maury asked his daughters and wife to leave the room. His last words, recorded verbatim, were "all's well," a nautical expression meaning calm conditions at sea. His body was placed on display in
13250-408: Was five. He wanted to emulate the naval career of his older brother, Flag Lieutenant John Minor Maury , an officer in the U.S. Navy, who caught yellow fever after fighting pirates . As a result of John's painful death, Matthew's father, Richard, forbade him from joining the Navy. Maury strongly considered attending West Point to get a better education than the Navy could offer. Instead, he obtained
13375-540: Was inspired by Psalm 8, "Thou madest him to have dominion over the works of thy hands... and whatsoever passeth through the paths of the seas." As officer-in-charge of the United States Navy office in Washington, DC , called the "Depot of Charts and Instruments," the young lieutenant became a librarian of the many unorganized log books and records in 1842. On his initiative, he sought to improve seamanship by organizing
13500-595: Was made by way of China , the Philippines , the Indian Ocean , and the Cape of Good Hope . Ship chaplain Charles Samuel Stewart published a book about the voyage. After nearly four years, Vincennes arrived back in New York on 8 June 1830, becoming the first U.S. Navy ship to circumnavigate the Earth . Two days later the ship was decommissioned. Following repairs and recommissioned, Vincennes then operated in
13625-528: Was neither the freedom of enslaved people nor the amelioration of slavery in Brazil, but rather an absolution for slaveholders of Virginia and other southern states. Maury wrote to his cousin, "Therefore I see in the slave territory of the Amazon the SAFETY VALVE of the Southern States." Maury wanted to open up the Amazon to free navigation in his plan. However, Emperor Pedro II 's government firmly rejected
13750-561: Was next assigned to the Home Squadron and placed under the command of Commander Franklin Buchanan , a distinguished officer destined to become the first Superintendent of the United States Naval Academy . She sailed to the West Indies and cruised off the Mexican coast until the summer of 1844. Though this duty proved relatively uneventful, Vincennes did rescue two grounded English brigs off
13875-483: Was not an enslaver, but he did not actively oppose the institution of slavery. An article tying his legacy in oceanography to the slave trade suggested that Maury was ambivalent about slavery, seeing it as wrong but not intent on forcing others to free enslaved people. However, a recent article explaining the removal of his monument from Monument Avenue in Richmond, Virginia, illustrated a proslavery stance through deep ties to
14000-634: Was offered the position as its first president but turned it down because of his age. He had previously been suggested as president of the College of William & Mary in Williamsburg, Virginia , in 1848 by Benjamin Blake Minor in his publication the Southern Literary Messenger . He considered becoming president of St. John's College in Annapolis, Maryland, the University of Alabama , and
14125-490: Was one of the principal advocates for founding a national observatory and he appealed to a science enthusiast and former U.S. president, Representative John Quincy Adams , for the creation of what would eventually become the Naval Observatory. Maury occasionally hosted Adams, who enjoyed astronomy as an avocation, at the Naval Observatory. Concerned that Maury always had a long trek to and from his home on upper Pennsylvania Avenue, Adams introduced an appropriations bill that funded
14250-545: Was ordered abandoned and destroyed to prevent her capture, and her engineer set a slow match to the vessel's magazine while her men took refuge on other ships. However, her engineer cut the burning fuse and threw it overboard before the magazine could explode and, after the Confederate vessels withdrew early in the afternoon, Vincennes was refloated. After the Confederate attack, the Union sloop-of-war continued on blockade duty off
14375-648: Was ordered to assist in the occupation of Head of Passes , Mississippi River , and remain there on blockade duty. Though the Federal warships did successfully deploy, on 12 October 1861 the Confederate metal-sheathed ram Manassas and armed steamers Ivy and James L. Day drove the Union blockaders from Head of Passes in the Battle of the Head of Passes , forcing the Screw sloop-of-war Richmond and Vincennes aground. Vincennes
14500-461: Was ordered to assume command of the blockade off Ship Island, Mississippi , and to guard the pass out of Mississippi Sound. While so deployed, boat crews from the vessel and Clifton captured the barge H. McGuin in Bay St. Louis, Mississippi , on 18 July 1863. Vincennes also reported the capture of two boats laden with food on 24 December. Vincennes remained off Ship Island for the remainder of
14625-491: Was pardoned by the federal government and returned to the US, accepting a teaching position at the Virginia Military Institute in Lexington, Virginia, holding the chair of physics. While in Lexington, he completed a physical survey of Virginia, which he documented in the book The Physical Geography of Virginia . He had once been a gold mining superintendent outside Fredericksburg and had studied geology intensely during that time, so he
14750-661: Was proclaimed Emperor of Mexico. At an early stage in the war, the Confederate States Congress assigned Maury and Francis H. Smith, a mathematics professor at the University of Virginia, to develop a system of weights and measures. Maury was in the West Indies on his way back to the Confederacy when he learned of its collapse. The war had brought ruin to many in Fredericksburg, where Maury's immediate family lived. On
14875-719: Was refitted with a light spar deck and declared the flagship of the South Sea Surveying and Exploring Expedition to the Antarctic region. Commanded by Lieutenant Charles Wilkes , the expedition sailed from Hampton Roads in August 1838, and made surveys along the South American coast before making a brief survey of Antarctica in early 1839. Entering into the South Pacific in August and September 1839, her cartographers drafted charts of that area that are still used today. Following survey operations and other scientific work along
15000-676: Was soon after the Brussels conference that Prussia, Spain, Sardinia, the Free City of Hamburg, the Republic of Bremen, Chile, Austria, Brazil, and others agreed to join the enterprise. The Pope established honorary flags of distinction for the ships of the Papal States, which could be awarded only to the vessels that filled out and sent to Maury in Washington, DC, the Maury abstract logs. Maury's stance on
15125-548: Was the Report Of The Scientific Results of the Exploring Voyage of H.M.S. Challenger during the years 1873–76 . Murray, who supervised the publication, described the report as "the greatest advance in the knowledge of our planet since the celebrated discoveries of the fifteenth and sixteenth centuries". He went on to found the academic discipline of oceanography at the University of Edinburgh , which remained
15250-494: Was the first comprehensive work on oceanography to be published. In 1825, at 19, Maury obtained, through U.S. Representative Sam Houston , a midshipman's warrant in the United States Navy. As a midshipman on board the frigate USS Brandywine , he almost immediately began to study the seas and record methods of navigation. When a leg injury left him unfit for sea duty, Maury devoted his time to studying navigation, meteorology, winds, and currents. He became Superintendent of
15375-509: Was the most ambitious research oceanographic and marine zoological project ever mounted until then, and led to the classic 1912 book The Depths of the Ocean . The first acoustic measurement of sea depth was made in 1914. Between 1925 and 1927 the "Meteor" expedition gathered 70,000 ocean depth measurements using an echo sounder, surveying the Mid-Atlantic Ridge. In 1934, Easter Ellen Cupp ,
15500-471: Was to overcome this problem and clear the passage to India around Africa as a viable maritime trade route, that a systematic plan of exploration was devised by the Portuguese. The return route from regions south of the Canaries became the ' volta do largo' or 'volta do mar '. The 'rediscovery' of the Azores islands in 1427 is merely a reflection of the heightened strategic importance of the islands, now sitting on
15625-556: Was well-equipped to write such a book. He aimed to assist war-torn Virginia in rebuilding by discovering and extracting minerals, improving farming, etc. He lectured extensively in the United States and abroad. He advocated for creating a state agricultural college as an adjunct to Virginia Military Institute. This led to the establishment at Blacksburg of the Virginia Agricultural and Mechanical College , later renamed Virginia Polytechnic Institute and State University, in 1872. Maury
