Bonpland's real name was Goujaud, and he was born in La Rochelle, a coastal city in France. After serving as a Surgeon in the French army, and studying in Paris, he accompanied Alexander von Humboldt during five years of travel in Mexico, Colombia and the districts bordering on the Orinoco and Amazon rivers. In these explorations he collected and classified about 60 000 plants that were, until then, mostly unknown in Europe. He later described his findings in “Plantes equinoxiales” (Paris, 1808-1816).Many animals and plants are also named in his honour, including the squid Grimalditeuthis bonplandi and the orchid Ornithocephalus bonplandi.

Discoverer: H.M.S Challenger, 1873 The 'Challenger Deep', near the SW end of the Marianas Trench, is the greatest depth in the world oceans. It was named formally by UK's HMS 'Challenger' (there in 1951) to commemorate her predecessor also named HMS Challenger that visited the region in 1875 on her 1872-1874 world voyage, there obtaining a rope sounding of 4,500 fathoms (8,230m). Over the years, the search for the point of maximum depth has involved many vessels. The first definitive depth for that world maximum locality, 10,915 ± 10 m, was determined by Dr. R. L. Fisher aboard R/V 'Stranger' (SIO) in 1959. Six months later the bathyscaphe 'Trieste' dove at that locality and found the same depth, ±5 m, by manometer. In 1984, the S/V 'Takuyo' of the Japan Hydrographic Department, surveyed the whole extent of the 'Deep' revealing that the pocket had three depressions deeper than 10,800m, the easternmost being deepest at 10,914m±. The 1959 to 1984 results all lie within recognised precision, 10,920± 10m, the value here cited.

Proposer: Directorate of Hydrography and Navigation, Brazil, Aug. 2011Accredited by: SCUFN (Sep. 2011)After discussion on the feature it was decided that the name be accepted for the northwestern rift, but there is insufficient bathymetric data to prove the feature extends to the southeast, and so the southeastern part remains unnamed.Cruzeiro do Sul is the name of a five star constellation that indicates the South Pole (in English: South Cross). It is used as a national symbol by several southern nations and also appear in the Brazilian flag. The feature proposed is located in the Cruzeiro do Sul deformation zone, already described in scientific works.

One year later, he assumed an associate professor position at the world renowned University of Berlin.Heinrich Wilhelm Dove's influence on the scientific world was such that there is a crater on the moon, the Dove crater, named after him. He was also presented with the Copley Medal in 1853 because of his many achievements. Under the chair of Alexander von Humboldt in 1828, a Conference of German Naturalists took place in in Berlin. Humboldt, the senior scientist and accepted meteorologist, developed special relation and friendship to Heinrich Dove, which lasts over 30 years. Many experiments conducted by Dove, were based on the methods developed by Alexander von Humboldt. Heinrich Wilhelm Dove regarded Humboldt as fundamental scientist and founder of modern research.

Maximum Depth: ~ 3000 mThe proposed trench coincides with the collision area of the Carnegie Ridge with the continental slope. The maximum depths along this feature are approximately 3000 m, which is significantly lower than the Colombian Trench to the north and the Peru Trench to the south. This is due to the different tectonic processes which have created the trenches along this system. The northern extent of the Peru-Chili Trench and the southern extent of the Peru Trench are also separated by a tectonic collision zone, i.e. that of the Nazca Ridge and the continental slope, expressed as relatively shallow trench.

Dufek, Expedition SO213/1, Jan. 2011Accredited by: SCUFN (Sep. 2011) Named after Christian Gottfried Ehrenberg (April 19, 1795 – June 27, 1876), German Naturalist, Zoologist, comparative Anatomist, Geologist, and Microscopic, one of the most famous and productive scientists of his time. Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi. Ehrenberg was appointed professor of medicine at Berlin University in 1827. In 1829 he accompanied Humboldt through eastern Russia to the Chinese frontier. After his return he began to concentrate his studies on microscopic organisms, which until then had not been systematically studied. For nearly 30 years Ehrenberg examined samples of water, soil, sediment, blowing dust and rock and described thousands of new species, among them well-known flagellates such as Euglena, ciliates such as Paramecium aurelia and Paramecium caudatum, and many fossils, in nearly 400 scientific publications. He was particularly interested in a unicellular group of protists called diatoms, but he also studied, and named, many species of radiolaria and forminifera.These researches had an important bearing on some of the infusorial earths used for polishing and other economic purposes; they added, moreover, largely to our knowledge of the microorganisms of certain geological formations, especially of the chalk, and of the marine and freshwater accumulations. Until Ehrenberg took up the study it was not known that considerable masses of rock were composed of minute forms of animals or plants. He also demonstrated that the phosphorescence of the sea was due to organisms.

Dr. Eötvös invented the Eötvös balance instrument and showed that, to a high degree of accuracy, gravitational mass and inertial mass are equivalent. Because the instrument is very sensitive and not suitable for data mass production, it was replaced by the gravimeter. However, the Eötvös balance is still used today for special geodetic and geophysical applications. Eötvös founded the Hungarian Society for Mathematics in 1885, and was active in improving educational standards in Hungary.

At an early age, he accompanied his father on several scientific expeditions, including James Cook's second voyage to the Pacific. His report from that journey, A Voyage Round the World, contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster was admitted to the Royal Society at the early age of twenty-two and came to be considered one of the founders of modern scientific travel literature.After returning to continental Europe, Forster turned toward academia. He traveled to Paris to seek out a discussion with the American revolutionary Benjamin Franklin in 1777. He taught natural history at the Collegium Carolinum in Kassel (1778–1784), and later at Academy of Vilna (Vilnius University) (1784–1787). He then (1788) became head Librarian at the University of Mainz. Most of his scientific work during this time consisted of essays on botany and ethnology, but he also prefaced and translated many books about travels and explorations, including a German translation of Cook's diaries. In the spring of 1790, Forster and the young Alexander von Humboldt started from Mainz on a long journey through the Southern Netherlands, the United Provinces, and England, which eventually finished in Paris. The impressions from the journey were described in a three volume publication (Views of the Lower Rhine, from Brabant, Flanders, Holland, England, and France in April, May and June 1790), published 1791–1794.

The crew of the Hansa consisted of 13 men. In October 1869, the ship was milled by the ice and finally sank on October 22 at a position 70°32’N, 21°W approximately 10 km from the East Greenland coast. The crew managed to survive the winter in a shelter, while drifting on the sea ice southward along the eastern coast of Greenland. In June 1870, the crew got to the coast by boat and reached the Moravian Herrnhut mission at Frederiksdal/Friedrichsthal near Cape Farewell, from where they got back to Germany.

Schwabenland (December 1938-April 1939). He obtained a PhD in Geology from the university in Berlin, then became a voluntary teaching assistant at the Mineralogical and Petrographic Institute in Berlin. He had strong polar interests and organised geological and glaciological expeditions to Sweden, Norway and Iceland between 1924 and 1934. In summer 1938 he used the new slow-flying Fieseler Storch aircraft to undertake a photographic exploration of the geography of Svalbard, publishing a travel report as a popular book, and making the first coloured aerial movie in the Arctic. Herrmann also had a special interest in volcanoes, and was appointed a member of the Santorin-Expedition to investigate the eruption of one the volcanoes of the Mediterranean island of Santorini, in 1925-26. He later participated in expeditions to volcanoes in Iceland and Italy (in 1932, 1936, 1937, and 1939). Herrmann described himself as a teacher and polar researcher. Having been wounded during the first World War, he was exempt from military service in the second. As a member of the Freemasons he was not a member of the National Socialist Party and as a consequence was never promoted as teacher. In addition to teaching, he published books and papers and gave lectures and radio broadcasts on geology and geography. His later books included "Die Pole der Erde" (The Poles of the Earth; 1950) and "Die Werkstatt Vulkane" (The Volcano Workshop; 1963). In 1947 he became docent of geography in Bederkesa and at the teacher training college in Celle, and later in Osnabrück.

He was a natural scientist and explorer. Between 1799 and 1804 he travelled in Latin America, exploring and describing it for the first time in a manner generally considered to be a modern scientific point of view.In Latin American expedition, he had important result about Casiquiare canal and determined the exact position for bifurcation. Mainly, these Latin American expeditions greatly affected physical geography and meteorology. Humboldt explained interrelations of all physical sciences and that was helped to determine the places where specific plants grew. Most modern and sophisticated scientific instruments were used to get the truth from the nature. He explained the rate of decrease in mean temperature with the increase in altitude, origin of tropical storms and Earth's magnetic fields variation from the poles to the equator.Humboldt's studies were extended to social researches which were conducted in Cuban Spanish colony. As a result of the expeditions and researches he wrote a work consisting of 36 volumes which took him 30 years to complete. His works created the new branches of science like plant geography as basis of agricultural science, climatology, volcanology and the model of Earth's magnetic field.

He enrolled as a sailor in 1853, before he attended the naval school in Bremen. After becoming a captain, Koldewey studied mathematics, physics, and astronomy at the universities of Hannover and Göttingen between 1866 and 1867. Carl Koldewey was given the leadership of the first German Arctic expedition as captain of ship Grönland in the summer of 1868. He had the choice of either advancing northwards as far as possible along Greenland's east coast or to reach so-called Gillis-Land by travelling around Spitsbergen. But adverse conditions and strong ice floes prevented him from reaching both destinations. Finally he reached his northmost latitude of 81°5' near Spitsbergen and returned. The second expedition consisted of a two-vessel convoy: Germania and Hansa- under the command of Carl Koldewey. The Germania made it through the pack ice during late summer, explored the region around Sabine Island, Little Pendulum Island and Shannon. On September 13, 1869, the ship wintered near the south coast of Sabine Island. In late July 1870, Germania was able to raise anchor and continue the expedition, until it returned to Bremerhaven, most of the way by sail, on September 11, 1870.

He was a seasoned polar whaler – 47-years old - who had sailed most of the seven seas. The season before (1937/38) he had been Fangleiter (whaling manager) on the German whaling ship Jan Wellem in the Antarctic. Kraul started his career in whaling as a worker at the whaling station of the Compania Argentina de Pesca in Grytviken during World War I. Then he became seaman on a whale catcher, was promoted pilot, and later in the 1920s sometimes held the well-paid position of whale shooter. In1928 he earned his captain’s ticket. Theoretical learning was not his strong point, and in his final examination he failed in physics, meteorology and oceanography, passing the other subjects with the lowest possible grades. Kraul’s strengths were practical, and he could tell the most exciting stories about his experiences. His life story up to and including his experiences on the Schwabenland was published as:- Kraul, O., 1939, Käpt’n Kraul Erzählt. F.A.Herbig, Berlin, 240 pp. Kraul’s experience of sailing steel hulled ships unprotected against ice in icy seas was invaluable to Ritscher, the leader of the expedition, and got the ship out of some difficult situations when the ship was manouevering among sea ice close to the coast. Avoiding ice was imperative as the main task of the expedition was to launch aerial survey aircraft (seaplanes) to map Dronning Maud Land for the first time (the major achievement of the expedition). The Schwabenland was a catapault ship borrowed from Lufthansa who used it for the South America mail run. But the returning seaplanes had to land on water – hence the need to avoid sea ice at all costs. On one occasion Schwabenland was nearly crushed by sea ice, until Kraul found the leads that would enable her to escape. Schwabenland made major bathymetric discoveries including undertaking the first N-S echo-sounding transect down the mid-Atlantic Ridge in the S Atlantic, and one

She obtained geological education at the Far Eastern Polytechnic Institute, Vladivostok, and finished her academic training in 1960. She worked later at the Pacific division of the Shirshov Institute of Oceanology (since 1968, the Pacific Oceanology Institute), in Vladivostok, and participated in a number of seagoing expeditions as marine geologist. In 1964-1965 Natasha attended the 36th cruise of "Vitjaz" as petrologist, and contributed to the first discovery of the upper mantle rocks outcrops, dredged in the rift zone of the Karlsberg Ridge (NW-branch of the Mid-Ocean Ridge system in the Indian Ocean). She actively collaborated in studies of the mid-oceanic ridges of the Atlantic, Indian Ocean and Pacific. In 1971 she moved to the laboratory of Geomorphology and Tectonics at the Shirshov Institute of Oceanology, Moscow. She joined the 49th cruise of "Vitjaz" in the West Pacific, led the dredging program in the newly discovered Vitjaz Trench (north of the North Fiji Basin) and made first discoveries of upper mantle rocks outcrops. From 1992 until her decease in Moscow on 25.01.2010, Natasha Kurentsova worked in the laboratory for Geomorphology and Tectonics of the Ocean Floor at GEOCHI. She attended the 21st and 29th cruises of r/v "Akademik Boris Petrov" and on several Antarctic expeditions of the German RV "Polarstern” in the Atlantic and Pacific Sectors of the Southern Ocean where she collected rock samples from 300 sites, followed by intensive petrological and geochemical analyses at the GEOCHI. Based on the results she published series of articles in scientific magazines of the Russian Academy of Sciences.

They constitute a wide-ranging ethnicity composed of various groups who shared a common social, religious and economic structure, as well as a common linguistic heritage. Their influence extended between the Aconcagua River and Chiloé Archipelago and later eastward to the Argentine pampa. Historically, Mapuches were known as Araucanians (araucanos). They resisted heavily the conquest attempts by the Spanish and the Incas. The Mapuches make up about 4% of the Chilean population, and are particularly concentrated in Araucanía Region, which is located 600 km south of Santiago de Chile and north of the city Valdivia. Mapuche Ridge is located approx. 1000 km off the Araucanian Region of Chile coast.

Dufek, Expedition SO213/1, Jan. 2011Accredited by: SCUFN (Sep. 2011)Named after Matthew Fontaine Maury, born near Fredericksburg, Virginia, 14 January 1806; died Lexington, Virginia, 1 February 1873. Maury is considered as one of the fathers of global ocean mapping. From 1868 he was professor of physics at Virginia Military Institute United States, until his death. Maury’s scientific career began with two articles and a textbook on navigation. These made him an obvious choice for the U.S. Navy exploring expedition, his main interest lay in improving the technology of navigation, for which the science of the earth was more relevant than the science of the heavens. Maury’s insight that the data on winds and currents in these logs could be brought together to chart the general circulation of atmosphere and ocean was the basis for his chief contribution to science. Maury began to publish his Wind and Current Charts—beginning with the North Atlantic in 1847— and to issue them free to mariners in exchange for abstract logs of the winds and currents of their voyages. The result was a series of charts and (after 1850) accompanying sailing directions that presented a climatic picture of the surface winds and currents for all the oceans. Inspired by the example of Alexander von Humboldt, many men of science in the second quarter of the nineteenth century were devoting their efforts to collecting on a large scale the data of physical phenomena on earth.Maury’s scientific achievements were organizational and empirical like those from Humboldt; they earned him the praise of European leaders of science, including Humboldt. Beginning with an article on the Gulf Stream in 1844, Maury developed theories of the general circulation of atmosphere and ocean, first in articles and in Explanation and Sailing Directions to Accompany the Wind and Current Charts (1850 et seq.) and then in his best-known work, Physical Geography of the Sea (1855).

This was resulted in publication of an atlas of seafloor morphology around Japan (Mogi, 1979). He found in situ deformation of a subducting seamount and demonstrated this is an excellent example of a plate subduction, giving a huge impact on the marine geology/geophysics community (Mogi and Nishizawa,1980).

He studied in Pisa at the Regia Scuola Normale Superiore where he obtained a degree in Mathematics and in Physics in 1940 and got a University teaching qualification in Earth Physics in 1948. In 1949 he founded in Trieste the Osservatorio Geofisico Sperimentale (OGS) and was its Director until 1963 and its President until 1975. From 1971 to his death he was member of the Editorial Board for the International Bathymetric Chart of the Mediterranean (IBCM) and Vice-Chairman of the Consultation Group for Ocean Mapping (CGOM) of IOC. He led also to the compilation (for the IOC of UNESCO) first of the IBCM 1:1.000.000, published in 10 sheets in 1981, and later on (1985-99) of the Overlay Sheets with the gravity and magnetic anomalies, the seismicity and other geological and geophysical parameters. Carlo Morelli has achieved many scientific goals. The largest part of his experimental research is pertinent to Gravimetry. He proposed and led an endeavor which lasted for 20 years: the global gravity net and its standardization, which was officially adopted by the International Association of Geodesy at the Moscow 1971 General Assembly. This reference system (IGSN 71: International Gravity Standardization Net) represents also nowadays a basic instrument for the international cooperation and is universally adopted. Carlo Morelli is the author of 327 scientific papers (215 of which as the only author), mostly in international journals.

Krocker, Expedition 64PE306, May 2009Accredited by: SCUFN (Sep. 2011)Named from “Niemegk”, a small city located 60 kilometres west of Potsdam and hosting one of the world famous geomagnetic observatories. The “Magnetic Observatory Adolf Schmidt” was installed in 1930 replacing the observatory in Potsdam because the expansion of subway lines there led to bad influences. Looking for a new location, the regional government had to agree on a contract imposing that no large industry be installed in the future within 50 kilometre distance to minimize magnetic disturbances. The city fathers of Niemegk signed this treaty even if this meant a limitation for the city’s development. However, this decision was a success for the science and since then, international competitions repeatedly show that the quality of magnetic measurements is one of the three best worldwide.

He contributed immensely to the development of geophysics not only as an outstanding scientist but also as a great leader. From 1973 to 1991, he served as Secretary General of International Union of Geodesy and Geophysics (IUGG), and was the Honorary Secretary General of IUGG until his death. His tenure lasted so long because he had an extraordinary ability to meet the expectations of his colleagues. One of his successes as Secretary General was the adhesion of China as member of IUGG, for which he showed all his skill in diplomatic matters. During his long and fruitful scientific career, Paul Melchior had been Director of the International Center for Earth Tides (1958-995), President of the Commission of Earth Rotation of the International Astronomical Union (1967-1970), and President of CODATA (1974-1978).Paul Melchior studied mathematics at the Free University of Brussels. His professional career started as assistant at the Royal Observatory of Belgium in 1949. He became the Director in 1981 and served in that capacity until his retirement in 1990. Paul Melchior had a profound attachment to the Observatory. His contributions to the development of geophysics and geodesy at the Observatory are countless and brought great renown to his grateful Institute. For his dedication for science and his international reputation, in 1993 King Baudouin bestowed upon him the title of Baron. Paul Melchior began his career as an astronomer. From 1950 to 1957, he spent long nights observing at the Askania Great Meridian Circle in Uccle. After compiling the data, he published the most precise star catalogue of that time. Soon, he was interested in the Earth's rotation. He then developed the complete theory of the motions of the Earth's rotational axis and its link to Earth's tides. This became his main subject of research. He began measuring Earth tides in 1957 with the Verbaandert-Melchior quartz tiltmeters.In 1958, he was the first to analyze Earth tide observations using an electronic computer, the famous IBM 650. In 1968, Paul Melchior founded, with Johnny Flick, the Underground Laboratory of Walferdange in Luxembourg. In 1969, with Prof.

Harvey Pirie was a versatile man of science and pioneer explorer of the Sub-Antarctic. Shortly after receiving a science and medical degree at Edinburgh, Dr Harvey Pirie joined the Scottish National Antarctic Expedition (1902-4) on “S.Y. Scotia” under William S. Bruce. The naturalist team explored East Falkland, Laurie Island in the South Orkneys, and made the first oceanographic investigation of the Weddell Sea. After sighting Antarctica and naming the coast seen Coats Land, they returned to the Clyde via Gough Island and Cape Town. Dr. Pirie was the author of the expedition report "Zoological Log of Omond House, Scotia Bay". After a period in Scottish private practice, Pirie became a bacteriologist; he joined the Colonial Medical Service in 1913 and served in Kenya. In 1918 he organized the bacteriological services at the South African Institute for Medical Research in Johannesburg, and became deputy-director, 1926-41. Large submarine features northern of South Scotia Ridge are named after members of the Scotia Expedition (Bruce, Herdman, Pirie).

In his writings he was very aware of the astronomical discoveries of his time and he fitted numerous independent pieces of knowledge into usable generalizations. He was the first to popularize and may actually have invented the grid system of latitude and longitude we are still using. He established the convention of orienting maps with the north at the top ; he divided the earth sphere in 360 degrees.

Snow), Nov. 2003Accredited by: SCUFN (Sep. 2011)This deep was discovered during the YK03-09-Leg 2 cruise of R/V Yokosuka. During the cruise, two dives of the submersible Shinkai 6500 (dives #799 & #800) investigated the feature for the first time. The dives recovered mantle peridotites and gabbros, indicating that the feature is geologically a rift basin within the Parece Vela Basin. Geologically, this feature also represents a “tectonic window”, an important setting to study Earth’s lithosphere. Because of this important discovery by Shinkai 6500, the feature is named after that submersible.

Takuyo, Nov. 1998 - May 1999.Accredited by: SCUFN (May 2008).Named after Dr. Risaburo Tayama who was one of the pioneers on submarine topographical and geological researches in Japan. He had worked on bathymetric and geological surveys in Japan and the Western Pacific Ocean for more than 20 years. He devoted 12 years to studies of coral reef islands in the Western Pacific Ocean. His detailed descriptions of geomorphology and geology of coral reefs contributed to an understanding of how coral reefs develop. He also compiled bathymetric and geomorphological maps of a large region (130°-174°E and 4°S-30°N), which already depicts this guyot as a seafloor high. The guyot is a drowned coral reef and is linked with his lifework study.

Minimum Depth: ~ 1400 to 1500 m;Maximum Depth: ~ 5500 m; Total Relief: ~ 4000 m.The guyot is one of the constituents of the “Marcus-Wake Seamount Group” in the Northwest Pacific Ocean. It has a flat-topped summit. Its basal area is about 90×100 km².

Depth: from less than 150 m to over 740 m.Ulsan Seachannel is located about 55 km to the east of Ulsan harbour, starting from the coast of the Korean peninsula. The estuarine appearance of the feature on the continental shelf gradually becomes a relatively narrow depression with steep sides and a substantial gradient as the feature traces down the continental slope into Ulleung Basin. The seachannel was most likely formed by headward erosion of the continental slope by turbidity currents transporting terrestrially-derived sediments from the Korean peninsula. Its width is approximately 5 km and its total length is approximately 50 km.

Taken from the AGSO Bathymetric Map "Cuvier". Formerly, Zenith Seamount (See DMA Chart 5446, June 1933 and Australian INT 708, May 1975). It was incorrectly called Wallaby Plateau on GEBCO 5.09. It was also noted at SCGN/10 that the eastern plateau (23°40' S - 108°35' E) was named Cuvier (Wallaby) Plateau on Map "Cuvier" and it was therefore considered that another Wallaby Plateau in the same area would have been misleading. The Sub-Committee decided that the name Wallaby would be kept for the Saddle only which is close by. Although Veevers, in his article, has named Quokka Rise the feature north of Cuvier (Wallaby) Plateau, the Sub-Committee took no position on this suggestion.
