S. Geological Survey (USGS) as a scientific research organization. For more than 100 years, the USGS has examined the geological structure and resources of the nation. The information provided by the USGS is helpful in promoting the health and safety of the people, as well as in the management of our natural resources.World War II and the development of sonar technology significantly improved our knowledge of the ocean basins. By the late 1950's, the scientific community had knowledge of the depths of the world's oceanic trenches and the existence of submarine mountain chains. In 1962, Congress extended the geologic investigations of the USGS into the marine realm. The data collected over the past 35 years have dramatically altered our perception of the sea floor.K&@sF% MOn March 10, 1983, President Reagan formally declared the Exclusive Economic Zone (EEZ) of this nation to extend over 200 nautical miles beyond its shorelines in the Atlantic, Pacific, and Arctic Oceans, the Gulf of Mexico, and the Caribbean and Bering Seas. The EEZ includes more than 13 million square kilometers (sq km) offshore, an area surprisingly much larger than our on-shore territory! This declaration gave the United States sovereign rights to all natural resources within the EEZ and provided a mandate for reconnaissance exploration.D(DI1 0'm-ƸThe EEZ, in comparison to long-studied onshore areas, clearly is a new frontier. By 1980, before the images featured on this CD-ROM were collected, the general bathymetry of the EEZ was known but the detailed geology was not well known. Only with such detailed knowledge of the sea floor could we begin to understand human impact on the oceans, appraise its resource potential, and be aware of existing geologic hazards. However, the problems encountered in mapping the sea floor are not unlike the challenges of mapping the Moon, Mars, Venus, and other planetary bodies. The environments are hostile, so scientists rely on remote-sensing techniques. Mapping the EEZ requires scientists to use geologic knowledge and intuition to synthesize information from several data sources._sFGL1 0"ޏThe USGS designed the EEZ-SCAN program to provide reconnaissance maps of the newly declared EEZ. During 1984 through 1991 extensive deep-water portions of the EEZ were mapped systematically using sidescan sonar, a remote-sensing technology that uses sound to collect images of the ocean floor. The resulting sidescan-sonar images, shown on this CD-ROM, are no less remarkable than the first photographs from the far side of the Moon. These reconnaissance views of the sea floor provide a "road map" to aid the next generation of studies of the geologic processes and resources of our oceans' floors.s(ILK fR"p MԀReferencesTop of page@GLL1K * 2L1McPlate Tectonics7L1M% $Plate Tectonics;LMg x AVScript(hfs,"top_pt.ave")"|Cross-Section of Tectonic Plates(caption)_1M>} Ȁ{ 7 AVScript(hfs,"open_g2.ave")MF?CThe size of the Earth -- about 12,750 kilometers (km) in diameter -- was known by the ancient Greeks, but it was not until the turn of the 20th century that scientists determined that our planet is made up of three main layers: crust, mantle, and core [image A and caption]. This layered structure can be compared to that of a boiled egg. The crust, the outermost layer, is rigid and very thin compared with thM>Le other two. Like the shell of an egg, the Earth's crust is brittle and can break. Below the crust is the mantle (the white of a boiled egg), a dense, hot layer of semi-solid rock approximately 2,900 km thick. At the center of the Earth lies the core (yolk), which is nearly twice as dense as the mantle.^M q =À 9IAVScript(hfs,"open_g7.ave")şThe surface of our planet has been shaped by plate-tectonic processes. In the early 1960's, the emergence of the theory of plate tectonics started a revolution in the earth sciences. Scientists now have a fairly good understanding of how the tectonic plates move and how such movements relate to earthquake activity, sea-floor topography, and almost all geologic processes active on the surface of the Earth.In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of numerous plates. The theory of plate tectonics states that the Earth's outermost layer is fragmented into a dozen or more plates that are moving relative to one another [image B and caption].H>Uc AVScript(hfs,"open_g1.ave")6爀 jThe tectonic plates do not randomly drift or wander about the Earth's surface. They are driven by the slow movement of hot, softened mantle that lies below the rigid plates. The mobile rock beneath the rigid plates is believed to be moving in a circular manner somewhat like a pot of thick soup when heated to boiling. The heated soup rises to the surface, spreads and begins to cool, and then sinks back to the bottom of the pot where it is reheated and rises again. This cycle is repeated over and over to generate what scientists call a convection cell or convective flow [image C and caption]. This convection within the mantle moves the tectonic plates along the Earth's surface in much the same way as a conveyor belt. 0 C T惀߃檵 G This conveyor belt activity causes the plates to be perpetually "recycled." New crust is formed at the mid-ocean ridge spreading centers while older crust is destroyed as it sinks into subduction zones. The size of the Earth has not changed significantly during the past 600 million years, and probably not since shortly after its formation 4.6 billion years ago. The Earth's unchanging size implies that the crust must be destroyed at about the same rate as it is being created.U= H _܀ Because the tectonic plates are constantly in motion, the areas where they meet, boundary zones, are geologically very dynamic. The main types of plate boundaries are: divergent, convergent, and transform. Divergent boundaries occur along spreading centers (often on the ocean floor) where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest. Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge that encircles the Earth. This immense system of submarine mountain chains -- more than 50,000 km long and, in places, more than 800 km across -- zigzags between the continents, winding its way around the globe like the seam on a baseball. Rising an average of about 4,500 meters(m) above the sea floor, the global mid-ocean ridge overshadows all the mountains in the United States except for Mount McKinley (Denali) in Alaska (6,194 m).j ֿxAVScript(hfs,"open_g5.ave")rr̀x0݀jLbs{AVScript(hfs,"open_g6.ave")*$AVScript(hfs,"open_g8.ave")CConvergent boundaries occur where tectonic plates collide. When two plates converge, one is usually subducted under the other, and in the process a deep sea-floor trench is formed. The plate being subducted sinks into the trench and is destroyed or recycled back into the mantle. Frequent earthquakes occur due to the stress of this plate interaction. As the subducted plate begins to melt, some of the newly formed magma rises through the overriding crust to form volcanoes. When oceanic and continental tectonic plates collide, the relatively dense oceanic crust is subducted beneath the more buoyant continental crust [image D and caption]; the trench occurs on the ocean floor along the continental margin, and the volcanoes develop along the continental borderlands. When an oceanic plate is subducted beneath another oceanic plate, volcanoes are slowly built on the ocean floor, sometimes rising above sea level to form island volcanoes [image E and caption]. Such volcanoes are typically strung out in chains called island arcs, which closely parallel the trenches. The Pacific Ocean is encircled by sea-floor trenches and active volcanoes. This is commonly known as "The Ring of Fire" [image F and caption]. } Ȁ9*ƀAVScript(hfs,"open_g4.ave")斍kDTransform boundaries occur where two plates slide horizontally past one another. These large faults or fracture zones commonly offset the active spreading ridges (divergent plate boundaries), producing zigzag plate margins, and are generally defined by shallow earthquakes. Most transform faults are found on the ocean floor. However, a few occur on land, for example the San Andreas fault zone in California is a transform boundary.The vast majority of earthquakes and volcanic eruptions occur near plate boundaries, but there are some exceptions. For example, the Hawaiian Islands, which are entirely of volcanic origin, have formed in the middle of the Pacific Ocean more than 3,200 km from the nearest plate boundary. The distinctive linear shape of the Hawaiian Island-Emperor Seamounts chain resulted from the Pacific Plate moving over a deep, stationary hot spot in the mantle, located beneath the present-day position of the Island of Hawaii [image G and caption]. Heat from this hot spot produced a persistent source of magma by partly melting the overriding Pacific Plate. The magma, which is lighter than the surrounding solid rock, then rises through the mantle and crust to erupt onto the sea floor, forming an active seamount. Over time, countless eruptions cause the seamount to grow until it finally emerges above sea level to form an island volcano. Continuing plate movement eventually carries the island beyond the stationary hot spot, cutting it off from the magma source, and volcanism ceases. As one island volcano becomes extinct, another develops over the hot spot, and the cycle is repeated. This process of volcano growth and death, over many millions of years, has left a long trail of volcanic islands and seamounts across the Pacific Ocean floor.s(jcK fR"Ac/w e[ReferencesTop of page?1 ?ERemote SensingBc% :Remote Sensing with GLORIA9g t AVScript(hfs,"top_rs.ave")"IǀSidescan-Sonar Data Collection(caption)J buMH%"ޏRemote-sensing technologies provide a unique view of otherwise inaccessible areas, as well as powerful analytical capabilities. Most imaging techniques that we are familiar with, such as photography or satellite imaging of the earth, use reflected light as their data source. Sonar technology uses soucnd waves to create images called sonographs. This technology is an essential tool in the study of the deep, dark sea floor.The first sidescan-sonar system was developed in 1960 by the Institute of Oceanographic Sciences (IOS) in the United Kingdom for use in shallow water. When the submarine Thresher was lost in 1963, the need for deep-water search capability became clear. In 1969 IOS introduced GLORIA (Geologic LOng Range Inclined ASDIC), the first sidescan-sonar system capable of deep-water geologic surveying. In 1977 they produced the next generation, GLORIA II, which was used to collect the imagery presented on this CD-ROM.?%  The GLORIA II sidescan-sonar system, used by the U.S. Geological Survey to map the U.S. Exclusive Economic Zone (EEZ), was specifically designed to map the large-scale morphology and texture of sea-floor features in the deep ocean. To map efficiently a large area such as the EEZ, some detail had to be sacrificed. GLORIA cannot resolve human debris such as pieces of shipwrecks, but it can map an area the size of New Jersey in a single day! The images shown on this CD-ROM have a pixel resolution of 500 meters (m). Higher resolution GLORIA images (50 m pixels) are available on other CD-ROMs (see Additional Data section of EEZ-View Text).] p  ݗAVScript(hfs,"open_g11.ave")wRiAcoustic images of the sea floor are formed by aiming sound waves at the sea floor and recording the returning sound waves. These images are graphic presentations of the interaction of acoustic energy with the sea floor, not optical views of the sea floor. The GLORIA II sonar vehicle is 8 m long, weighs 2.25 tons in air, and is neutrally buoyant in sea water. This torpedo-shaped "fish" is towed at about 50 m depth behind a ship by a heavy cable containing electrical wires that transmit the signals between the ship and the fish [image A and caption]. The electronic instruments in the fish send out a pulse of sound that travels through the water and is reflected by the sea-floor sediments. Computers aboard the ship then record the amount of energy (backscatter) that returns from the sea floor and use that data to create the image. ? = H'ꑀ"Sidescan" refers to the shape of the sonar beam, which fans out to the sides and scans a wide "swath" of sea floor. The energy beam is confined to the plane perpendicular to the ship's track, forming a narrow acoustic beam in the horizontal plane and a broad beam in the vertical plane. With every sound pulse the fish emits, it images one strip of sea floor as much as 22 km wide on each side of the fish. As the ship tows the fish along its course, it insonifies successive areas of the sea floor, building a long swath of imagery pulse by pulse. The fish is towed along parallel tracklines back and forth over an area, like mowing a lawn, with a small amount of overlap between adjacent swaths. With proper navigational control, these parallel swaths of sonar imagery can be mosaicked together to produce large areas of continuous sea-floor imagery, similar to the method used in aerial photography. @3 4U=ÀThe mosaic is a gray-scale image of the acoustic backscatter variations of the sea floor. The darkness or lightness of a feature on the mosaic is a function of how much sound is backscattered from the sea floor. White represents the most acoustic backscatter, and black represents the least. The amount of backscattered acoustic energy is controlled by the sea-floor topography, roughness of the sea-floor surface, and the sea-floor composition.Sea-floor topography dramatically affects the amount of backscatter received by the sidescan fish. When viewed from the ship's trackline, a positive-relief feature, such as a volcano, usually appears as a bright zone (the slope facing the sonar beam) with a dark zone (the acoustic shadow) behind it. @c Conversely, a negative-relief feature, such as a canyon, usually appears as a dark zone (the near wall is shadowed) followed by a bright zone (the far wall is facing the sonar beam).m WC% Hard rock ocean-floor substrates such as seamounts, volcanoes, and oceanic ridges reflect a lot of acoustic energy (high backscatter), and are recorded as bright areas on the sidescan image. Bright patterns also can be caused by certain sedimentation patterns and by steep sediment-covered slopes facing the sonar beam. Sea-floor materials such as soft mud tend to absorb much of the acoustic signal, returning very little energy (low backscatter), and appear on the image as dark areas. Dark patterns also have a variety of causes, but are commonly caused by acoustic shadows and certain variations in sediment type.@0E1 0QJ52USGS scientists have interpreted the geology of many of the sonar images from the EEZ.

This spreading center is part of the global ridge system that extends 50,000 km through all the ocean basins. The Blanco Fracture Zone accommodates the offset between the Juan de Fuca Ridge and the Gorda Ridge [image A and caption]. Cascadia Channel, a major sediment conduit, can be clearly traced from offshore central Oregon south to where it snakes through the Blanco Fracture Zone, and then heads off the mosaic to the west [image B and caption]. The channel transports sediment from the Columbia and Fraser River systems westward more than 500 km across the Juan de Fuca and Pacific Plates. The Cascadia Subduction Zone is active along the Washington, Oregon, and northern California coasts: here the North American continental plate overrides both the Gorda and the Juan de Fuca oceanic plates, causing large earthquakes and creating the string of Cascade volcanoes in Oregon and Washington. The Mendocino Fracture Zone (MFZ) is a right-lateral transform fault that forms the boundary between the young crust of the Gorda Plate to the north and the older, more sediment-covered Pacific Plate to the south [image C and caption] and accommodates the relative motion between these two tectonic plates.

The Aleutian Arc is a string of volcanoes that has formed along the northern boundary of the Pacific plate where the oceanic crust is subducted beneath the Bering Sea at the Aleutian Trench. Although a geologic-interpretation map of this GLORIA image is not yet available, there are some interesting features to be noted. The oceanic crust entering the Aleutian Trench is relatively old, and during its history has accumulated a thick blanket of terrigenous and hemipelagic sediment that has buried and smoothed over the original rough topography of the igneous crust [image A and caption]. Additional sediment accumulates on the plate just prior to its subduction in the bathymetric low of the Aleutian Trench.

During the accretionary process, this originally flat-lying sedimentary blanket is folded and stacked up, forming long, steep-sided ridges that parallel the trench [image C and caption].

This influx of sediment has buried almost all traces of the igneous crust, forming a flat, largely featureless sea floor that slopes gently down to the west.

One of the most striking patterns visible in the southern Bering Sea basin is the variations in the reflectivity of the sea floor formed by the diffuse distributional pathways traveled by sediment flowing across the basin floor [image B and caption]. Earthquakes along the Aleutian Arc trigger large submarine landslides around the margins of the Bering Basin. One clear example is a 30 by 40 km section of sediment that slid down the western flank of Umnak Plateau [image C and caption].

Although a geologic-interpretation map of this sidescan-sonar image is not yet available, there are some interesting features to be noted. The Gulf of Alaska has been the site of steadily increasing sediment accumulation for at least the last 11 million years. During the last 2.5 million years the combination of high mountains, high snowfall rates, and active glaciers in Alaska has produced an extremely high erosion rate. Large quantities of sediment have been delivered to the Gulf of Alaska where the major onshore glacial and fluvial drainage systems reach the coast. The Gulf of Alaska has a very narrow continental shelf, and a steep continental slope. This geometry insures that most of the sediment eroded from the mountain belts is rapidly transported to the deep-sea floor in the Gulf.9aKׂ ܀e. CAVScript(hfs,"box_ga1.ave")湜}AVScript(hfs,"box_ga3.ave")ĵSediment that reaches the deep-sea floor in a continuous or pulsating stream is often delivered by a dilute density-driven flow called a turbidity current. These currents are driven by gravity, tend to channelize, [image B and caption] and behave similarly to a river flowing across the land. Because the flows are gravity driven and always must go downslope, complex interactions with submarine obstacles can occur. In the southern Gulf, a deep-sea channel crosses the axis of a seamount chain in a very convoluted fashion [image C and caption]. In the central Gulf the Surveyor Channel meanders downslope, first southwestward across the Gulf, then northwestward to the deep Aleutian Trench.

At the hot spot, magma from the Earth's mantle continually rises through the ocean crust, and lava erupts frequently to slowly build a volcanic seamount. Many of the seamounts grow tall enough to break the surface of the water, forming the Hawaiian Islands. Because they sit on the ocean floor in water depths greater than 5 km, the Hawaiian volcanoes are some of the tallest mountains in the world! xX ~_AVScript(hfs,"box_hw01.ave")[As the Pacific Plate continues to move northwestward, it carries the once-active volcano away from the magma source. Over time the extinct volcano gradually sinks below sea level due to its weight and continued cooling of the ocean crust. Meanwhile, a new volcano develops on the adjacent area of sea floor newly moved over the hot spot. All of the Hawaiian volcanoes in this area are younger than about 8 million years, the youngest toward the southeast. Loihi Seamount is the newest volcano growing off the southeast coast of the Island of Hawaii.

The lava has erupted from fissures that cross the crest of the Hawaiian Arch. Thin tongues of lava more than 100 km long have flowed both southward and northward from this topographic high. The southern ends of some lava flows are interbedded with landslide debris from the Hawaiian Islands, showing that this lava field developed at the same time as the nearest Hawaiian volcanoes, apparently in response to the same hot spot.

The submarine landslide deposits are visible on the imagery directly offshore of the cliffs. The Hilina Slump is offshore on the southeast flank of the active volcano Kilauea on the Island of Hawaii. It moves episodically along steep faults which extend to depths of more than 5 km.

Use the magnifier tool to enlarge the area around Gardner Pinnacles (Image A yellow box) and you will see the white speckly marks characteristic of such debris.CEt AVScript(hfs,"ybox_hw2.ave")"Nov ݖ㈀(Remove) yellow boxesReferencesTop of pageL1+a ԊHNorthwestern Hawaiian RidgeCEԊ% <Northwestern Hawaiian Ridgex LX B AVScript(hfs,"top_hw3.ave")"Sidescan-Sonar ImageTԊ<  .dπ"ޏx*ƀ 7{ kDThe Hawaiian Islands are the southern end of a 5,000-km-long string of underwater volcanoes called the Hawaiian-Emperor Chain. Volcanoes of the Hawaiian chain form a long, discontinuous ridge called the Hawaiian Ridge. The GLORIA image of the Exclusive Economic Zone (EEZ) of the northwestern Hawaiian Ridge covers about 700,000 square kilometers (sq km) of sea floor. Within this sidescan-sonar image the row of non-data areas in blue traces the axis of the northwest-southeast-trending ridge. Over the past 80 million years, the Hawaiian-Emperor Chain developed, one volcano after another, as the Pacific Plate moved slowly northwestward over a stationary hot spot. At the hot spot, magma from the mantle continually rises through the ocean crust, and lava erupts frequently to slowly build a volcanic seamount. Many of the seamounts grow tall enough to break the surface of the water, forming the Hawaiian Islands. As the Pacific Plate continues to move northwestward, it carries the once-active volcano away from the maL<Egma source. Over time the extinct volcano gradually sinks below sea level due to its weight and continued cooling of the ocean crust. Twenty to thirty million years ago several of the Hawaiian seamounts and small islands extending southeastward through the center of this area were much larger islands.`Ld AVScript(hfs,"box_hw32.ave")&\@\Although a geologic-interpretation map of this GLORIA image is not yet available, there are some interesting features to be noted. Unlike the Hawaiian volcanoes farther to the southeast, most volcanoes in this segment of the chain do not form a continuous ridge. Instead, the Hawaiian volcanoes in this area occur among older seamounts (probably older than 75 million years) that are aligned in rows trending south-southeast rather than east-southeast like the rest of the Hawaiian Ridge. These older seamounts are thought to represent the traces of ancient hot spots, similar to the Hawaiian hot spot but no longer active. North of Lisianski Island, for example, are three guyots believed to have formed over such a hot spot [image A and caption].5<| ƀs sH惀߃AVScript(hfs,"box_hw31.ave")Aw拍The Murray Fracture Zone, visible north of the Hawaiian ridge in the Central Hawaiian GLORIA mosaic, can barely be seen in the southwest part of this image. This fracture zone consists of groups of linear, east-west-trending faults caused by offsets in the mid-ocean ridge. The pattern of short, linear bands perpendicular to the fracture zone is called spreading fabric and is composed of volcanic ridges that formed, one after another, at the spreading center of the mid-ocean ridge. Here the fracture zone is obscured by sediment from islands; the faint expression of the sea-floor spreading fabric gives a clue to its location. It also appears to be much wider than it is in the central Hawaiian EEZ; evidently the spreading center underwent some significant changes when this part of the sea floor formed about 110 to 130 million years ago. Additional evidence for such changes can be seen in the far northern part of the mosaic, where unusual "swirly" patterns in the spreading fabric [image B and caption] suggest that the spreading center of the East Pacific Rise spun off a series of very small tectonic plates as it "dueled" with other spreading centers at a triple junction.hX ~AVScript(hfs,"box_hw33.ave")ӇAlso visible in this mosaic are several large landslides from Hawaiian volcanoes and older guyots. A good example occurs near Lisianski Island [image C and caption]. Such landslides are quite common throughout the Hawaiian Islands; at least 68 landslides are visible on the GLORIA images between Hawaii and Midway Island, each more than 20 km long.CHt AVScript(hfs,"ybox_hw3.ave")"? ㉧F(Remove) yellow boxesReferencesTop of page@1P  Johnston Island7H% $Johnston Islandw 6W ~B AVScript(hfs,"top_ji.ave")"Sidescan-Sonar ImagevJ AVScript(hfs,"box_ji3.ave")Q{kD{ *ƀ.dπ"ޏJohnston Island marks the center of this circular Exclusive Economic Zone (EEZ) [image A and caption]. It is the northernmost of the Line Islands, a series of seamounts and linear volcanic ridges created as oceanic crust traveled over local hot spots. This 4,200-km-long island chain is bordered by the Mid-Pacific Mountains and the Molokai Fracture Zone. The GLORIA image of the Johnston Island EEZ covers about 450,000 square kilometers (sq km) of sea floor. Although a geologic-interpretation map of this sidescan-sonar image is not yet6JH available, there are some interesting features to be noted.6N= HkI `Necker Ridge (top center of mosaic) is an elongate ridge that trends NE-SW from the Hawaiian EEZ to the Johnston Island EEZ. Necker Ridge is 600 km long and ranges in width from about 20 km at its northern and southern ends to more than 40 km along the central segment of the ridge. It rises as much as 3 km above the surrounding abyssal plain. Necker Ridge originally formed through volcanic processes and has been sculpted by mass movement. Numerous slumps and canyons incise the flanks of the ridge, providing sediment to the small deep-sea fans along the base. Unlike the very large deep-sea fans off the east or west coast of the North American continent, these fans are less than 10 km across.J <%AVScript(hfs,"box_ji2.ave")ct=qkӀ\U2nF ?g9eHorizon Guyot is a flat-topped volcanic ridge running parallel to and lying southeast of Necker Ridge [image B and caption]. It is 300 km long, 70 km wide, and rises 3,500 meters (m) above the adjacent abyssal plain. The guyot has been submerged since the Late Cretaceous. Erosional processes are quite active on Horizon Guyot. Well-developed talus aprons are present along the base of the guyot. Along the western flank large-scale faulting occurs, and chaotic, slump-like features predominate. Numerous terraces expose basement rock. These terraces are visible on the GLORIA image as bright areas along the western rim of the guyot. In contrast, the eastern flank shows a predominance of rills and gullies that occur in a dendritic pattern.dN  AVScript(hfs,"box_ji1.ave")S^AVScript(hfs,"box_ji5.ave")oTwo distinct strands of the Molokai Fracture Zone (MFZ) are visible in the northeast section of the GLORIA image [image C and caption]. These bright lineations are multiple ridges and basins caused by offsets in the East Pacific Rise spreading center, now being overridden by North America. The MFZ extends from central Baja California westward across the Pacific Ocean, through the Hawaiian EEZ and into the area shown in this mosaic. While the southern strand disappears before Karin Ridge [image D and caption], the northern strand continues in the western part of the Johnston Island EEZ."&  AVScript(hfs,"box_ji4.ave")twRiAVScript(hfs,"box_ji6.ave")'TNIn the northeast section of the GLORIA image lies a series of low abyssal hills [image E and caption]. The mottled backscatter pattern in that area is intriguing. While it may represent recent lava flows, it is most likely a large field of manganese nodules. Known manganese nodule fields have a similar backscatter pattern, and manganese encrustations are common in this area.The southern half of the mosaic is dominated by numerous seamounts, many previously undiscovered [image F and caption]. The geologic reason for this scattering of seamounts is not clear, but may be related to the early history of the Pacific Plate.C  s AVScript(hfs,"ybox_ji.ave")"K 㗫|(Remove) yellow boxesReferencesTop of pageO& +1u a < +qjIKingman Reef and Palmyra AtollF! q% BKingman Reef and Palmyra Atollw +W ~B AVScript(hfs,"top_kp.ave")"Sidescan-Sonar Image1qAn c.dπAVScript(hfs,"box_kp2.ave")4r"ޏThis GLORIA image shows about 200,000 square kilometers (sq km) of sea floor, representing the northern two-thirds of the Exclusive Economic Zone (EEZ) around KingmaA n Reef and Palmyra Atoll in the central Pacific Ocean [image A and caption].
