RV Knorr was a research vessel formerly owned by the U.S. Navy and operated by the Woods Hole Oceanographic Institution for the U.S. research community in coordination with and as a part of the University-National Oceanographic Laboratory System (UNOLS) fleet. On March 14, 2016, Knorr was officially transferred to the Mexican Navy and renamed Rio Tecolutla . She was replaced at Woods Hole by the RV  Neil Armstrong . Knorr is best known as the ship that supported researchers as they discovered the wreck of the RMS Titanic in 1985. R/V Knorr ( AGOR-15 ) has traveled more than a million miles—the rough equivalent of two round trips to the Moon or forty trips around the Earth. Her sister ship is the RV Melville .

72-622: R/V Knorr was named in honor of Ernest R. Knorr , a distinguished hydrographic engineer and cartographer who was appointed Chief Engineer Cartographer of the U.S. Navy Hydrographic office in 1860. Chief Engineer Knorr was one of the leaders of the Navy’s first systematic charting and surveying effort from 1860 to 1885. She was launched on August 21, 1968 at the Defoe Shipbuilding Company in Bay City, Michigan , Knorr

144-596: A dot map showing corn production in Indiana or a shaded area map of Ohio counties , divided into numerical choropleth classes. As the volume of geographic data has exploded over the last century, thematic cartography has become increasingly useful and necessary to interpret spatial, cultural and social data. A third type of map is known as an "orienteering," or special purpose map. This type of map falls somewhere between thematic and general maps. They combine general map elements with thematic attributes in order to design

216-572: A dynamic positioning system that allows the ship to move in any direction and to maintain a fixed position in high winds and rough seas. In 2005–2006, the ship was refitted to support a new “long-coring” system that can extract 150-foot (46 m) plugs of ancient sediments from the sea floor. Weighing nearly 25,000 pounds, the new piston-coring system is the longest in the U.S. research fleet (twice as long as existing systems). Knorr and its long-corer will allow scientists to sample deep, ancient sediments that are rich with historical information about

288-536: A star map on the equidistant cylindrical projection. Although this method of charting seems to have existed in China even before this publication and scientist, the greatest significance of the star maps by Su Song is that they represent the oldest existent star maps in printed form. Early forms of cartography of India included depictions of the pole star and surrounding constellations. These charts may have been used for navigation. Mappae mundi ('maps of

360-535: A 'sense of the other' in relation to nonconforming maps." Depictions of Africa are a common target of deconstructionism . According to deconstructionist models, cartography was used for strategic purposes associated with imperialism and as instruments and representations of power during the conquest of Africa. The depiction of Africa and the low latitudes in general on the Mercator projection has been interpreted as imperialistic and as symbolic of subjugation due to

432-436: A Dynamic Positioning System capable of holding the ship in position within one meter was installed providing capability for ocean drilling and other precise operations. During a 2005–2006 refit a 25,000 pounds (11,000 kg) long coring system capable of 150 ft (45.7 m), longest in the U.S. research fleet, deep cores was installed. The ship has anti-roll tanks and an ice-strengthened bow enabling her to work in all of

504-428: A decreased focus on production skill, and an increased focus on quality design , the attempt to craft maps that are both aesthetically pleasing and practically useful for their intended purposes. A map has a purpose and an audience. Its purpose may be as broad as teaching the major physical and political features of the entire world, or as narrow as convincing a neighbor to move a fence. The audience may be as broad as

576-399: A different direction. To print from the finished plate, ink is spread over the metal surface and scraped off such that it remains only in the etched channels. Then the plate is pressed forcibly against the paper so that the ink in the channels is transferred to the paper. The pressing is so forceful that it leaves a "plate mark" around the border of the map at the edge of the plate, within which

648-482: A few metres; the invention of OpenStreetMap in 2004, a global digital counter-map that allowed anyone to contribute and use new spatial data without complex licensing agreements; and the launch of Google Earth in 2005 as a development of the virtual globe EarthViewer 3D (2004), which revolutionised accessibility of accurate world maps, as well as access to satellite and aerial imagery. These advances brought more accuracy to geographical and location-based data and widened

720-408: A general-purpose world map because regions are shown as increasingly larger than they actually are the further from the equator they are. Mercator is also credited as the first to use the word "atlas" to describe a collection of maps. In the later years of his life, Mercator resolved to create his Atlas, a book filled with many maps of different regions of the world, as well as a chronological history of

792-581: A map is what comprise a map's deconstruction . A central tenet of deconstructionism is that maps have power. Other assertions are that maps are inherently biased and that we search for metaphor and rhetoric in maps. It is claimed that the Europeans promoted an " epistemological " understanding of the map as early as the 17th century. An example of this understanding is that "[European reproduction of terrain on maps] reality can be expressed in mathematical terms; that systematic observation and measurement offer

864-441: A map with a specific audience in mind. Oftentimes, the type of audience an orienteering map is made for is in a particular industry or occupation. An example of this kind of map would be a municipal utility map. A topographic map is primarily concerned with the topographic description of a place, including (especially in the 20th and 21st centuries) the use of contour lines showing elevation. Terrain or relief can be shown in

936-586: A metaphor for power. Political leaders could lay claim to territories through the use of maps, and this was greatly aided by the religious and colonial expansion of Europe. The Holy Land and other religious places were the most commonly mapped during the Renaissance. In the late 1400s to the late 1500s, Rome, Florence, and Venice dominated map-making and trade. It started in Florence in the mid-to late 1400s. Map trade quickly shifted to Rome and Venice but then

1008-466: A rare move, Ortelius credited mapmakers who contributed to the atlas, the list of which grew to 183 individuals by 1603. In the Renaissance , maps were used to impress viewers and establish the owner's reputation as sophisticated, educated, and worldly. Because of this, towards the end of the Renaissance, maps were displayed with equal importance of painting, sculptures, and other pieces of art. In

1080-505: A replacement for RV  Knorr , operated by Woods Hole Oceanographic Institution since 1970. The ship was constructed by Dakota Creek Industries of Anacortes, Washington and scheduled for completion in 2014 for entry into service in 2015. It was launched on 29 March 2014, christened by Carol Armstrong, passed sea trials 7 August 2015 and delivered to the Navy on 23 September 2015. A sister ship, RV  Sally Ride  (AGOR-28) ,

1152-534: A standard as compared to the 1:50,000 scale Canadian maps. The government of the UK produces the classic 1:50,000 (replacing the older 1 inch to 1 mile) " Ordnance Survey " maps of the entire UK and with a range of correlated larger- and smaller-scale maps of great detail. Many private mapping companies have also produced thematic map series. Thematic cartography involves maps of specific geographic themes, oriented toward specific audiences. A couple of examples might be

1224-416: A thin sheet of wax over the metal plate and uses ink to draw the details. Then, the engraver traces the lines with a stylus to etch them into the plate beneath. The engraver can also use styli to prick holes along the drawn lines, trace along them with colored chalk, and then engrave the map. Lines going in the same direction are carved at the same time, and then the plate is turned to carve lines going in

1296-400: A variety of ways (see Cartographic relief depiction ). In the present era, one of the most widespread and advanced methods used to form topographic maps is to use computer software to generate digital elevation models which show shaded relief. Before such software existed, cartographers had to draw shaded relief by hand. One cartographer who is respected as a master of hand-drawn shaded relief

1368-450: Is a close reproduction of a 1698 work by Nicolas de Fer . De Fer, in turn, had copied images that were first printed in books by Louis Hennepin , published in 1697, and François Du Creux, in 1664. By the late 18th century, mapmakers often credited the original publisher with something along the lines of, "After [the original cartographer]" in the map's title or cartouche . In cartography, technology has continually changed in order to meet

1440-473: Is an iconic example. Although the most widely used map of "The Tube," it preserves little of reality: it varies scale constantly and abruptly, it straightens curved tracks, and it contorts directions. The only topography on it is the River Thames , letting the reader know whether a station is north or south of the river. That and the topology of station order and interchanges between train lines are all that

1512-461: Is left of the geographic space. Yet those are all a typical passenger wishes to know, so the map fulfills its purpose. Modern technology, including advances in printing , the advent of geographic information systems and graphics software , and the Internet , has vastly simplified the process of map creation and increased the palette of design options available to cartographers. This has led to

1584-410: Is powered by a multi-drive low-voltage diesel electric propulsion system for efficiency and lower maintenance and fuel costs. Both Neil Armstrong -class ships have state of the art oceanographic equipment allowing deep ocean mapping and information technology for ship monitoring and worldwide land-based communication. Neil Armstrong has more than 130 square meters of adjustable lab space, supplied by

1656-469: Is the Swiss professor Eduard Imhof whose efforts in hill shading were so influential that his method became used around the world despite it being so labor-intensive. A topological map is a very general type of map, the kind one might sketch on a napkin. It often disregards scale and detail in the interest of clarity of communicating specific route or relational information. Beck's London Underground map

1728-460: Is the earliest known map is a matter of some debate, both because the term "map" is not well-defined and because some artifacts that might be maps might actually be something else. A wall painting that might depict the ancient Anatolian city of Çatalhöyük (previously known as Catal Huyuk or Çatal Hüyük) has been dated to the late 7th millennium BCE. Among the prehistoric alpine rock carvings of Mount Bego (France) and Valcamonica (Italy), dated to

1800-481: Is the study and practice of making and using maps . Combining science , aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: Modern cartography constitutes many theoretical and practical foundations of geographic information systems (GIS) and geographic information science (GISc). What

1872-619: The Argo , to search for the Titanic . The Navy agreed it would finance use of the RV Knorr for Ballard's Titanic search only if he first searched for and investigated the two sunken submarines, and found out the state of their nuclear reactors after being submerged for such a long time, and whether their radioactivity was impacting the environment. When they searched for the two submarines, Ballard and his team discovered that they had imploded from

1944-770: The Neil Armstrong -class research vessels , to be owned by the United States Navy and operated by Woods Hole Oceanographic Institution . Secretary of the Navy Ray Mabus announced on September 24, 2012, that the research vessel was to be named after Neil Armstrong , the first person to walk on the Moon and a former naval aviator who served in the Korean War . The ship was ordered in May 2010 as

2016-561: The Berlin Conference of 1884–1885. Before 1749, maps of the African continent had African kingdoms drawn with assumed or contrived boundaries, with unknown or unexplored areas having drawings of animals, imaginary physical geographic features, and descriptive texts. In 1748, Jean B. B. d'Anville created the first map of the African continent that had blank spaces to represent the unknown territory. In understanding basic maps,

2088-553: The Far East (which he learned through contemporary accounts from Arab merchants and explorers) with the information he inherited from the classical geographers, he was able to write detailed descriptions of a multitude of countries. Along with the substantial text he had written, he created a world map influenced mostly by the Ptolemaic conception of the world, but with significant influence from multiple Arab geographers. It remained

2160-522: The Kassite period (14th – 12th centuries BCE). The oldest surviving world maps are from 9th century BCE Babylonia . One shows Babylon on the Euphrates , surrounded by Assyria , Urartu and several cities, all, in turn, surrounded by a "bitter river" ( Oceanus ). Another depicts Babylon as being north of the center of the world. The ancient Greeks and Romans created maps from

2232-746: The North Star at night or the Sun at noon. Advances in photochemical technology, such as the lithographic and photochemical processes , make possible maps with fine details, which do not distort in shape and which resist moisture and wear. This also eliminated the need for engraving, which further speeded up map production. In the 20th century, aerial photography , satellite imagery , and remote sensing provided efficient, precise methods for mapping physical features, such as coastlines, roads, buildings, watersheds, and topography. The United States Geological Survey has devised multiple new map projections, notably

2304-583: The Werner projection . This was an equal-area, heart-shaped world map projection (generally called a cordiform projection) that was used in the 16th and 17th centuries. Over time, other iterations of this map type arose; most notable are the sinusoidal projection and the Bonne projection . The Werner projection places its standard parallel at the North Pole; a sinusoidal projection places its standard parallel at

2376-477: The printing press , quadrant , and vernier allowed the mass production of maps and the creation of accurate reproductions from more accurate data. Hartmann Schedel was one of the first cartographers to use the printing press to make maps more widely available. Optical technology, such as the telescope , sextant , and other devices that use telescopes, allowed accurate land surveys and allowed mapmakers and navigators to find their latitude by measuring angles to

2448-476: The 17th century, European cartographers both copied earlier maps (some of which had been passed down for centuries) and drew their own based on explorers' observations and new surveying techniques. The invention of the magnetic compass , telescope and sextant enabled increasing accuracy. In 1492, Martin Behaim , a German cartographer and advisor to the king John II of Portugal , made the oldest extant globe of

2520-526: The 4th millennium BCE, geometric patterns consisting of dotted rectangles and lines are widely interpreted in archaeological literature as depicting cultivated plots. Other known maps of the ancient world include the Minoan "House of the Admiral" wall painting from c.  1600 BCE , showing a seaside community in an oblique perspective, and an engraved map of the holy Babylonian city of Nippur , from

2592-619: The Amur River as the border between the Eurasian powers, and opened up trading relations between the two. This treaty's significance draws from the interaction between the two sides, and the intermediaries who were drawn from a wide variety of nationalities. Maps of the Enlightenment period practically universally used copper plate intaglio, having abandoned the fragile, coarse woodcut technology. Use of map projections evolved, with

2664-557: The Earth. In 1507, Martin Waldseemüller produced a globular world map and a large 12-panel world wall map ( Universalis Cosmographia ) bearing the first use of the name "America." Portuguese cartographer Diogo Ribero was the author of the first known planisphere with a graduated Equator (1527). Italian cartographer Battista Agnese produced at least 71 manuscript atlases of sea charts. Johannes Werner refined and promoted

2736-660: The Space Oblique Mercator for interpreting satellite ground tracks for mapping the surface. The use of satellites and space telescopes now allows researchers to map other planets and moons in outer space. Advances in electronic technology ushered in another revolution in cartography: ready availability of computers and peripherals such as monitors, plotters, printers, scanners (remote and document) and analytic stereo plotters, along with computer programs for visualization, image processing, spatial analysis, and database management, have democratized and greatly expanded

2808-505: The culmination of many map-making techniques incorporated into Chinese mercantile cartography. In 1689, representatives of the Russian tsar and Qing Dynasty met near the border town of Nerchinsk, which was near the disputed border of the two powers, in eastern Siberia. The two parties, with the Qing negotiation party bringing Jesuits as intermediaries, managed to work a treaty which placed

2880-433: The demands of new generations of mapmakers and map users. The first maps were produced manually, with brushes and parchment; so they varied in quality and were limited in distribution. The advent of magnetic devices, such as the compass and much later, magnetic storage devices, allowed for the creation of far more accurate maps and the ability to store and manipulate them digitally . Advances in mechanical devices such as

2952-801: The diminished proportions of those regions compared to higher latitudes where the European powers were concentrated. Maps furthered imperialism and colonization of Africa in practical ways by showing basic information like roads, terrain, natural resources, settlements, and communities. Through this, maps made European commerce in Africa possible by showing potential commercial routes and made natural resource extraction possible by depicting locations of resources. Such maps also enabled military conquests and made them more efficient, and imperial nations further used them to put their conquests on display. These same maps were then used to cement territorial claims, such as at

3024-432: The double hemisphere being very common and Mercator's prestigious navigational projection gradually making more appearances. Due to the paucity of information and the immense difficulty of surveying during the period, mapmakers frequently plagiarized material without giving credit to the original cartographer. For example, a famous map of North America known as the "Beaver Map" was published in 1715 by Herman Moll . This map

3096-479: The early seventeenth century, the Selden map was created by a Chinese cartographer. Historians have put its date of creation around 1620, but there is debate in this regard. This map's significance draws from historical misconceptions of East Asian cartography, the main one being that East Asians did not do cartography until Europeans arrived. The map's depiction of trading routes, a compass rose, and scale bar points to

3168-530: The equator; and the Bonne projection is intermediate between the two. In 1569, mapmaker Gerardus Mercator first published a map based on his Mercator projection , which uses equally-spaced parallel vertical lines of longitude and parallel latitude lines spaced farther apart as they get farther away from the equator. By this construction, courses of constant bearing are conveniently represented as straight lines for navigation. The same property limits its value as

3240-518: The field of cartography can be divided into two general categories: general cartography and thematic cartography. General cartography involves those maps that are constructed for a general audience and thus contain a variety of features. General maps exhibit many reference and location systems and often are produced in a series. For example, the 1:24,000 scale topographic maps of the United States Geological Survey (USGS) are

3312-424: The general public or as narrow as a single person. Mapmakers use design principles to guide them in constructing a map that is effective for its purpose and audience. The cartographic process spans many stages, starting from conceiving the need for a map and extending all the way through its consumption by an audience. Conception begins with a real or imagined environment. As the cartographer gathers information about

3384-409: The immense pressure at depth. It littered thousands of pieces of debris all over the ocean floor. Following the large trail of debris led them directly to both and made it significantly easier for them to locate them than if they were to search for the hulls directly. Using that lesson, they had Argo sweep back and forth across the ocean floor to find the Titanic's debris trail, following the trail to

3456-569: The making of maps. The ability to superimpose spatially located variables onto existing maps has created new uses for maps and new industries to explore and exploit these potentials. See also digital raster graphic . In the early years of the new millennium, three key technological advances transformed cartography: the removal of Selective Availability in the Global Positioning System (GPS) in May 2000, which improved locational accuracy for consumer-grade GPS receivers to within

3528-426: The map, whether in physical or electronic form. Once finished, the map is delivered to its audience. The map reader interprets the symbols and patterns on the map to draw conclusions and perhaps to take action. By the spatial perspectives they provide, maps help shape how we view the world. RV Neil Armstrong RV Neil Armstrong (AGOR-27) is the designation for a new oceanographic research ship , first of

3600-451: The most accurate world map for the next three centuries. The map was divided into seven climatic zones, with detailed descriptions of each zone. As part of this work, a smaller, circular map depicting the south on top and Arabia in the center was made. Al-Idrisi also made an estimate of the circumference of the world, accurate to within 10%. In the Age of Discovery , from the 15th century to

3672-731: The ocean and climate. In 1985, operated by the Woods Hole Oceanographic Institution , she was the ship that discovered the wreck of the RMS Titanic , using side scan sonar . The U.S. Navy was interested in finding out what happened to their missing nuclear powered attack submarines, the USS Scorpion and the USS Thresher , which sank in the 1960s. Robert Ballard approached the Navy about using his new deep sea underwater robot craft,

3744-445: The only route to cartographic truth…". A common belief is that science heads in a direction of progress, and thus leads to more accurate representations of maps. In this belief, European maps must be superior to others, which necessarily employed different map-making skills. "There was a 'not cartography' land where lurked an army of inaccurate, heretical, subjective, valuative, and ideologically distorted images. Cartographers developed

3816-415: The paper is depressed compared to the margins. Copper and other metals were expensive at the time, so the plate was often reused for new maps or melted down for other purposes. Whether woodcut or intaglio, the printed map is hung out to dry. Once dry, it is usually placed in another press to flatten the paper. Any type of paper that was available at the time could be used to print the map, but thicker paper

3888-492: The prints rather than having to create a new one. On the other hand, it is hard to achieve fine detail with the relief technique. Inconsistencies in linework are more apparent in woodcut than in intaglio. To improve quality in the late fifteenth century, a style of relief craftsmanship developed using fine chisels to carve the wood, rather than the more commonly used knife. In intaglio, lines are engraved into workable metals, typically copper but sometimes brass. The engraver spreads

3960-721: The range of applications for cartography, for example in the development of satnav devices. Today most commercial-quality maps are made using software of three main types: CAD , GIS and specialized illustration software . Spatial information can be stored in a database , from which it can be extracted on demand. These tools lead to increasingly dynamic, interactive maps that can be manipulated digitally. Field-rugged computers , GPS , and laser rangefinders make it possible to create maps directly from measurements made on site. There are technical and cultural aspects to producing maps. In this sense, maps can sometimes be said to be biased. The study of bias, influence, and agenda in making

4032-408: The sheet. Being raised from the rest of the block, the map lines cause indentations in the paper that can often be felt on the back of the map. There are advantages to using relief to make maps. For one, a printmaker doesn't need a press because the maps could be developed as rubbings. Woodblock is durable enough to be used many times before defects appear. Existing printing presses can be used to create

4104-479: The sixteenth century, maps were becoming increasingly available to consumers through the introduction of printmaking, with about 10% of Venetian homes having some sort of map by the late 1500s. There were three main functions of maps in the Renaissance: In medieval times, written directions of how to get somewhere were more common than the use of maps. With the Renaissance, cartography began to be seen as

4176-404: The subject, they consider how that information is structured and how that structure should inform the map's design. Next, the cartographers experiment with generalization , symbolization , typography , and other map elements to find ways to portray the information so that the map reader can interpret the map as intended. Guided by these experiments, the cartographer settles on a design and creates

4248-558: The time of Anaximander in the 6th century BCE. In the 2nd century CE, Ptolemy wrote his treatise on cartography, Geographia . This contained Ptolemy's world map – the world then known to Western society ( Ecumene ) . As early as the 8th century, Arab scholars were translating the works of the Greek geographers into Arabic. Roads were essential in the Roman world, motivating the creation of maps, called itinerarium , that portrayed

4320-459: The troubles of a coarse medium and so was able to express the looping cursive that came to be known as cancellaresca . There were custom-made reverse punches that were also used in metal engraving alongside freehand lettering. The first use of color in map-making cannot be narrowed down to one reason. There are arguments that color started as a way to indicate information on the map, with aesthetics coming second. There are also arguments that color

4392-634: The world as experienced via the roads. The Tabula Peutingeriana is the only surviving example. In ancient China , geographical literature dates to the 5th century BCE. The oldest extant Chinese maps come from the State of Qin , dated back to the 4th century BCE, during the Warring States period . In the book Xin Yi Xiang Fa Yao , published in 1092 by the Chinese scientist Su Song ,

Still, some additions were made to the Atlas after his death, and new editions were published after his death.

Knorr was designed to accommodate a wide range of oceanographic tasks, with two instrument hangars and eight scientific work areas; a fully equipped machine shop; three oceanographic winches; and two cranes. Knorr is equipped with sophisticated navigation and satellite communication systems, as well as

4680-618: The wreckage of the ship itself. It was announced on December 4, 2014, that the research vessel Knorr was being decommissioned after more than 40 years as the workhorse of the Woods Hole Oceanographic Institution research fleet. The ship's last full research cruise, with Chief Science Officer Richard W. Murray , was completed in December 2014. Knorr was transferred to the Mexican Navy in 2016, and

4752-449: Was delivered to Woods Hole on April 15, 1970. The ship was built with Cycloidal propulsion that was replaced during a 1989-1991 midlife refit at which time propulsion was changed to two azimuthing stern thrusters and a retractable bow thruster as well as the hull being lengthened from 246 ft (75.0 m) to 279 ft (85.0 m). The overhaul between 1989 and 1991 added 34 feet (10 m) of length to her midsection. In 2003

4824-522: Was first used on maps for aesthetics but then evolved into conveying information. Either way, many maps of the Renaissance left the publisher without being colored, a practice that continued all the way into the 1800s. However, most publishers accepted orders from their patrons to have their maps or atlases colored if they wished. Because all coloring was done by hand, the patron could request simple, cheap color, or more expensive, elaborate color, even going so far as silver or gold gilding. The simplest coloring

4896-422: Was launched 9 August 2014 to be operated by Scripps Institution of Oceanography under a renewable charter-party agreement. Neil Armstrong is a commercially designed mono hull research vessel, capable of coastal and deep ocean oceanography operations, and equipped with cranes and winches for over-the-side loading of research equipment and supplies, as well as accommodations for twenty-four scientists. The ship

4968-469: Was merely outlines, such as of borders and along rivers. Wash color meant painting regions with inks or watercolors. Limning meant adding silver and gold leaf to the map to illuminate lettering, heraldic arms, or other decorative elements. The early modern period saw the convergence of cartographical techniques across Eurasia and the exchange of mercantile mapping techniques via the Indian Ocean. In

5040-493: Was more durable. Both relief and intaglio were used about equally by the end of the fifteenth century. Lettering in mapmaking is important for denoting information. Fine lettering is difficult in woodcut, where it often turned out square and blocky, contrary to the stylized, rounded writing style popular in Italy at the time. To improve quality, mapmakers developed fine chisels to carve the relief. Intaglio lettering did not suffer

5112-609: Was overtaken by atlas makers in the late 16th century. Map publishing in Venice was completed with humanities and book publishing in mind, rather than just informational use. There were two main printmaking technologies in the Renaissance: woodcut and copper-plate intaglio , referring to the medium used to transfer the image onto paper. In woodcut, the map image is created as a relief chiseled from medium-grain hardwood. The areas intended to be printed are inked and pressed against

5184-609: Was replaced by a new $ 74 million research vessel, the RV Neil Armstrong .
