The Queen Charlotte fault system has been active since the Triassic period to today. The QCF is a trans-form boundary between the Pacic plate and the North American plate. The relationship of the QCT to the Queen Charlotte Fault (QCF) and the Pacific plate is unclear. Brown and W.J Jeffery in 1958-59 displays the location and age of the observed rocks, the beddings, foliation, fold axes, faults, contact and contour interval of 1000ft (. But in the late 18th century Queen Charlotte, wife of King George III (1738-1820), may have been the countrys first multiracial royal. The primary goal of the study was to gain a better understanding of the earthquake, tsunami, and underwater-landslide hazards throughout southeastern Alaska, as well as gather data to devel, Active traces of the southern Fairweather fault were revealed by light detection and ranging (lidar) and show evidence for transpressional deformation between North America and the Yakutat block in southeast Alaska. In fact, the Queen Charlotte Fault ruptured twice in recent years, raising concern over its potential to damage coastal and seabed infrastructure through southeastern Alaska and western British Columbia. But the Queen intervened to ensure Charlotte would not be known as 'Lady Charlotte', according to a royal historian. After a sleepless night of tsunami warnings and aftershocks, triggered by a massive earthquake off British Columbia's northwestern coast, Faye Beaulieu. Large anticlines lie seaward of and trend parallel to the fault. There was a conflict between the Queen and their son, the Prince of Wales, over who should assume the Regency should the King be declared unfit to rule. Epicenters were located near the Queen Charlotte-Fairweather fault and the Denali fault. A scattering of microearthquakes through the archipelago and the Coast Range and a concentration in the Glacier Bay region suggest that the seismicity may be more complex than the pattern indicated by the distribution of larger earthquakes. An official website of the United States government. A recently completed series of data publications led by the U.S. Geological Survey represents the first time the fault has been mapped using comprehensive, high-resolution marine geophysical approaches. The world's largest earthquakes occur along this type of plate boundary. Figure 5: This illustration represents a fold. In 1764, an eight-year-old Wolfgang Amadeus Mozart arrived in Great Britain with his family, as part of their grand tour of Europe. We're working to build upon Sitkas legacy as a research and educational community. USA, smartphone 907.747.8878 Queen Charlotte (born Sophia Charlotte of Mecklenberg-Strelitz) was the Queen of England from 1761-1818. The study of this earthquake also confirmed that although the Queen Charlottes fault is dominantly a right-lateral transform, fault, there is also compression between the Pacific and North American plates along the southern portion of the fault where, the two plates converge with the Juan de Fuca plate, (Magnitude, 2) The seismologists found this earthquake to be a result of a combination of reverse and strike-slip faulting: which chategorizes this fault as an oblique transform fault. Create your own unique website with customizable templates. 10 am - 2 pm, WednesdaySaturday : College of Wales, Aberystwyth (Wales). (Clague). Potential hydrocarbon source rocks include Upper Triassic-Lower Jurassic shales and limestones locally preserved below the basin and Tertiary shales within the deeper portions of the basin fill. There was margin subduction prior to the Eocene. Cordially. Barbara Stepko is a New Jersey-based freelance editor and writer who has contributed to AARP magazine and the Wall Street Journal. The Queen Charlotte Fault Zone (QCFZ) off western Canada is the northern equivalent to the San Andreas Fault Zone, the Pacific-North American plate boundary. This fault segment is bounded on the seaward side by a high, midslope ridge and by lower slope Quaternary( ) anticlines up to 35 km wide. The QCF formed off the west coast of the islands of Haida Gwaii upon the termination of margin subduction in the Eocene. Charlotte had the first evergreen in her house in 1800, decorating it with sweetmeats, almonds, fruits and toys. In 1761, when she turned 17, Princess Sophia was betrothed rather unexpectedly to the King of . In Browns article, they are compared to wraped panels of volcanic rock. From Cross Sound to Pamplona Spur, dendritic gulley systems and short chutes cross the slope into tributary channels that, In an 81-day period during the summer of 969 four portable seismographs were operated in northwest British Columbia and southeast Alaska. The North American Plate is made of continental crust, and the Pacific Plate is made of oceanic crust.

AK Additional partners include EXPRESS (Expanding Pacific Research and Exploration of Submerged Systems), University of Calgary, NOAA Hydrographic Services Division, Sitka Sound Science Center, Alaska Department of Fish and Game, and the National Science Foundation. Six large earthquakes have occurred along the Queen Charlotte Fault within the last hundred years: a magnitude 7 event in 1929, a magnitude 8.1 in 1949 (Canada's largest recorded earthquake since the 1700 Cascadia earthquake), a magnitude 7.8 in 1958, a magnitude 7.4 in 1970, a magnitude 7.8 in 2012, and a magnitude 7.6 in 2013.[4]. Like the San Andreas fault, the Queen Charlotte-Fairweather Fault separates the Pacific tectonic plate from the North American plate. According to the UK Royals' website, the "Queen's music-master was Johann Christian Bach, who was the eleventh son of the great composer Johann Sebastian Bach. Assoc. In fact, according to Rhimes, who is . [24][8] There is a distinct structural transition due to a change in the stress regime from pure shear in the southern QCF segment to simple shear in the central QCF segment as a result of convergence decreasing below a critical angle of approximately 15.[8]. The primary goal of the study was to gain a better understanding of the earthquake, tsunami, and underwater-landslide hazards throughout southeastern Alaska, as well as gather data to devel, 12201 Sunrise Valley Drive Reston, VA 20192, Woods Hole Coastal and Marine Science Center, Alaska Department of Fish and Game (ADFG), Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), Coastal and Marine Hazards and Resources Program, began mapping the fault in detail in 2015, Fairweather fault, the terrestrial portion of this tectonic system, EXPRESS (Expanding Pacific Research and Exploration of Submerged Systems), Earthquake Hazards in Southeastern Alaska, Pacific Coastal and Marine Science Center, EXPRESS: Expanding Pacific Research and Exploration of Submerged Systems, Core Preparation and Analysis Laboratory and Sample Repositories, Characterizing the Active Queen Charlotte-Fairweather Fault System, Coastal and Marine Hazards and Resources Program News, Pacific Coastal and Marine Science Center News, Woods Hole Coastal and Marine Science Center News. Study with Quizlet and memorize flashcards containing terms like Draw a map of an idealized tectonic plate and explain the earthquake hazards along each type of plate edge:, Sketch a map of the Arabian plate and explain the origin of the Iranian Holy Land, and Turkey earthquakes:, Explain why earthquakes at subduction zones are many times more powerful than spreading-center earthquakes: and more. The series will center on the queen's younger years when she arrives in London before she earns the power and prominence that we see her wield in Bridgerton. While the San Andreas fault is continental fault, both display similar faulting system. The second quake, just 200 miles to the north, generated a magnitude 7.5 event offshore of Craig, Alaska, rupturing a 70-mile long stretch of the fault. Meghan Markle in March 2018. Though born in Germany and a princess of Mecklenburg-Strelitz, Charlotte was directly descended from an African branch of the Portuguese Royal House. In 2017 and 2018 the NOAA survey vessel Fairweather collected bathymetry and acoustic-backscatter data u, In 2015 the U.S. Geological Survey, Pacific Coastal and Marine Science Center, in cooperation with the Alaska Department of Fish and Game (ADFG), collected bathymetry and acoustic-backscatter data near Cross Sound in southeast Alaska using a Reson 7111 multibeam echosounder mounded to the ADFG R/V Solstice. In 1765, King George became mentally ill. (Its now believed that he was suffering from porphyria, an inherited disorder stemming from the buildup of certain chemicals in the brain, but at the time the cause of his illness was unknown.). In addition, the relationship between Queen Charlottes fault and the system of faults around it could explain the shearing in the northwest direction. Portrait of King George III and Queen Charlotte of the United Kingdom. Based on information provided in Module 4.5, this ''area'' (Northern BC) is no longer in a seismic gap zone. J. We are conducting comprehensive onshore and offshore geologic and geophysical investigations to fully characterize the seismic potential of the Queen Charlotte-Fairweather Fault system in southeast Alaska. In 1761 she was selected unseen after the British king asked for a review of all eligible German Protestant princesses. The blue arrows illustrate the acting forces and the red arrows illustrate the resulting motion. In other words, the folds appear to be controlled by the northwest strike-slip fault and by the compression of the Pacific and North America plates. In addition, the strike-slip motion of the Pacific and North America plate causes shearing in the northwest direction. More than three-quarters of the states population live in an area that can experience a magnitude 7 earthquake. Young structures underlie the slope from Middleton Island to Pamplona Spur, but are absent from Pamplona Spur to Cross Sound. Earth Sci. UNM researchers study mysterious Queen Charlotte fault. It is Canada's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California. Queen Charlotte fault (54N) delineate patterns of brittle faulting linked to transform development since 50 Ma. You see, George wasn't looking for a political equal. Secure .gov websites use HTTPS I dont think a prisoner could wish more ardently for his liberty than I wish to be rid of my burden and see the end of my campaign. After the king was declared insane (1811 . Although most of the plate motion isaccommodated by the right-lateral Queen CharlotteFairweather Fault (QCFF) System, which has produced at least six M>7 earthquakes since 1920, The neotectonics of southern Alaska (USA) are characterized by a several hundred kilometerswide zone of dextral transpressional that spans the Alaska Range. Regents' Lecturer, Lindsay Lowe Worthington, and her team have set out to learn more about the mysterious Queen Charlotte fault . Queen Charlotte in the studio of Allan Ramsay, oil on canvas, (1762). Previous models for the accommodation of transpression include internal deformation of both plates adjacent to the plate boundary or oblique subduction of the oceanic plate; the latter has A team of geologists on a September expedition to map a major offshore earthquake fault north of Canada's Vancouver Island has discovered a surprising geologic feature deep beneath the waves: an. The blue plane illustrates the axial plane. We map the Holocene geomorphic expression of tectonic deformation along the southern 30 km of the Fairweather fault, which ruptured in the 1958 moment magnitude 7.8 earthquake. , Share sensitive information only on official, secure websites. ; (United States). The Queen Charlotte Fault lies between the North American Plate and the Pacific Plate. The Queen Charlotte fault is one of this type of fault. The shaking of the ground near an earthquake source made up of potentially damaging seismic waves of various types. The red line represents a wavelength. It appears to be the fastest moving continent-ocean strike-slip fault in the world. Speedy faults like the Queen Charlotte can trigger earthquakes and tsunamis more frequently than slower faults. ", "Magnitude 7.7 Queen Charlotte Islands Region.". the transform Queen Charlotte Fault (QCF) south of Haida Gwaii (Figure 1). [5] The same location also marks earthquake rupture boundaries between the 2013 Craig event[25] and the 1972 M7.6 Sitka event,[26][27] as well as the inferred intersection of the Chatham Strait Fault and the Aja Fracture Zone (FZ) with the Queen Charlotte Fault; the Aja FZ also marks an approximately 3 million year contrast in Pacific Plate crustal age. Aftershocks as large as 6.3 magnitude were reported. (Brown Bulletin 54, 38) Among a variety of sedimentary and plutonic rocks, an important amount of volcanic rocks is mostly found in the southern islands. Geol., Bull. Another large earthquake hit along that fault in 1972. A switch in relative plate motions at the Queen Charlotte Fault 10 million years ago produced consequent strain throughout the northern portion of the Western Cordillera, resulting in crustal thinning and decompression melting of oceanic island basalt-like mantle to create alkaline volcanism. Charlotte, meanwhile, became her husbands legal guardian, which placed her under a great deal of stress. A few folds on the sea floor are observable on the photo provided by Google Earth. Science. The queen founded orphanages and, in 1809, became the patron of Londons General Lying-in Hospital, one of the first maternity hospitals in Great Britain. The, A regional survey of the western Canadian continental margin from the central Queen Charlotte Island, 52/sup 0/40'N, to the Strait of Juan de Fuca, 47/sup 0/40'N, has been completed with the acoustic imaging system SeaMARC II. Figure 6: Fold systems along rocks from the Triassic, Jurassic, Cretaceous and Tertiaty periods. GLORIA images collected in 1989 along southeast Alaska and British Columbia strikingly show the active trace of the Fairweather-Queen Charlotte transform fault system beneath the outer shelf and slope; seismic-reflection data are used to track the fault system across the continental shelf where GLORIA data are not available. An active strike-slip boundary similar to Californias San Andreas fault, the Queen Charlotte Fault has produced five magnitude-7-and-higher earthquakes in the last 100 years and presents the greatest earthquake hazard to residents of southeast Alaska and western British Columbia. Alaska has more large earthquakes than the rest of the United States combined. The age of the rocks are illustrated and the formations that occured on this area are also displayed. The fault rupture began in the ocean bottom offshore from Graham Island and spread for more than three hundred miles along the Queen Charlotte Fault. In addition to multibeam sonar, their tools included seismic-reflection surveys that use sound to reveal rock layers beneath the seafloor, piston cores that bring up the top several meters of ocean sediment for further scrutiny, and cameras with powerful lights dragged just above the seabed. Write something about yourself. Data from this research are being used to refine the seismic hazard for southeastern Alaska, as well as to develop geologic models that can be applied to similar plate boundaries around the globe, said Peter Haeussler, USGS Geologist at the Alaska Science Center and a co-author of the data publications. The Queen Charlotte Fault forms a triple junction on its south with the Cascadia subduction zone and the Explorer Ridge (the Queen Charlotte Triple Junction ). In subsequent research expeditions (two in 2016, one in summer 2017, and another in fall 2017), additional data were collected along the underwater Queen Charlotte Fault. In Alaska, digital elevation models based on light detection and ranging and interferometric synthetic aperture radar data enabled our fault mapping at scales of 1:2,000 and 1:10, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), A bathymetric terrain model of multibeam sonar data collected between 2005 and 2018 along the Queen Charlotte Fault System in the Eastern Gulf of Alaska from Cross Sound, Alaska to Queen Charlotte Sound, Canada, Coastal and Marine Hazards and Resources Program, Woods Hole Coastal and Marine Science Center, Multibeam bathymetry and acoustic-backscatter data collected in 2017 and 2018 of Noyes Submarine Canyon and vicinity, southeast Alaska, Pacific Coastal and Marine Science Center, Multibeam bathymetry and acoustic-backscatter data collected in 2015 near Cross Sound, southeast Alaska, during field activity 2015-629-FA, Radiocarbon Data for Fairweather Fault Investigation, Glacier Bay National Park, Southeast Alaska (2021), Multibeam bathymetry and backscatter data collected in the eastern Gulf of Alaska during USGS Field Activity 2016-625-FA using a Reson 7160 multibeam echosounder, Systematic mapping of the ocean-continent transform plate boundary of the Queen Charlotte fault system, southeastern Alaska and western British ColumbiaA preliminary bathymetric terrain model, Geomorphic expression and slip rate of the Fairweather fault, southeast Alaska, and evidence for predecessors of the 1958 rupture, The Peters Hills basin, a Neogene wedge-top basin on the Broad Pass thrust fault, south-central Alaska, Groundwater and Streamflow Information Program. [4] This is similar to the 1970 earthquake, which also showed a strike-slip movement with a small but significant thrust component, consistent with relative plate motion. We can think of this fault system as the San Andreas of the north, said USGS Research Geophysicist Danny Brothers, a lead author of the publications. Hanging canyons of Haida Gwaii, British Columbia, Canada: Fault-control on submarine canyon geomorphology along active continental margins. The variability in the surficial and deep structures along the length of the margin is great and corresponds well with the postulated variations in the local ocean/continent motion vectors: motion along the southern Queen Charlotte Islands margin is primarily transform (about 55 mm/year) with a small component of convergence (about 10 mm/year); motion south of the triple junction at the Wilson Knolls is convergent but at a very slow rate (about 10 mm/year); and motion along the central and southern Vancouver Island margin is nearly orthogonal to the coast and more rapid (about 40 mm/year). Digital, The Neogene Peters Hills basin is a small terrestrial basin that formed along the south flank of the Alaska Range during a time in which there was regional shortening. Sitka Over the last 100 years, the Queen Charlotte-Fairweather fault system has produced large-magnitude earthquakes affecting both Canada and the U.S. To fill in missing details about its offshore location and structure, USGS uses sophisticated techniques to truly understand the faults hazard potential. In California, the San Andreas Fault is the plate boundary, running east of Los Angeles and west of San Francisco, but in actuality the plate boundary is diffuse and spreads as far east as Salt Lake City, Utah as part of the Basin and Range. Below are data and web tools related to this project. [29], The 2012 magnitude 7.8 earthquake struck off the western coast of Haida Gwaii at around 8:10pm Pacific Time on Saturday 27 October. This was the biggest quake in Canadian territory since 1949. Here, some other facts about this most unusual womans life: She had fifteen children, thirteen of whom survived to adulthood. The Queen Charlotte Fault (QCF) forms a transpressionalplate boundary, and is as active as other major transform fault systems (i.e. The Queen Charlotte Basin was formed during the last 43 Ma by episodes of extension paired with a belt of subsidence and uplift. Dear Mrs. Meryem Berrada, Read another story from us:The life of Mary Queen of Scots Married 3 times, imprisoned and her untimely end. While Mt. Queen Charlotte's fault by meryem berrada. [3][8] Through geologic time, a change in pacific plate motion beginning as recently as approximately 6 Ma[11] or as early as approximately 12 Ma[12] caused an increase in convergence along the entire length of the fault and initiated underthrusting[13] along the southern segment where convergence is highest,[2] a process that ultimately led to the 2012 Haida Gwaii thrust earthquake. This resulted in a 1,720-foot (524-meter) tsunami that crashed into a mountainside, the largest ever recorded tsunami run-up. We are fortunate to have a strong partnership with Natural Resources Canadas Geological Survey of Canada, so that we can examine the fault system in its entirety." The bathymetry and acoustic-backscatter data are provided as GeoTIFFs with 10-m spatial res. This magnitude 7.8 earthquake caused as much as 21 feet of horizontal movement and up to 3 feet of vertical movement and was felt as far south as Seattle, Washington. Pet. Soc. [7] The two segments are collectively called the Queen Charlotte-Fairweather Fault System. [5] The entire approximately 900km offshore length has ruptured in seven greater than magnitude 7 events during the last century, making the cumulative historical seismic moment release higher than any other modern transform plate boundary system.[6]. The blue arrows illustrate the acting force. In this case, Queen Charlottes fault carries the strain to the Cascadia subduction zone below it and the Alaska subduction zone above it. The National Seismic Hazard Maps developed by the USGS show the spatial probability of peak earthquake-driven ground motion levels. Researchers from NOAA, U.S. Geological Survey and their partners have completed the first high-resolution, comprehensive mapping of one of the fastest A team of USGS scientists spent two weeks in the isolated Glacier Bay National Park, exploring one of the fastest-moving faults in North America. The Queen Charlotte's fault is often compared to the San Andreas fault. 1995 made a case the Explorer Plate is no longer subducting.14 They interpreted a zone of seismicity cutting across the Explorer plate to represent the new Pacific-America plate boundary. Plate 1 illustrates a motion similar to that of the Pacific plate, Plate 2 illustrates that of the North America plate. Santa Cruz, CA 95060 The Queen Charlotte Fault forms a triple junction south with the Cascadia subduction zone and the Explorer Ridge (the Queen Charlotte Triple Junction). The second quake, just 200 miles to the north, generated a magnitude 7.5 event offshore of Craig, Alaska, rupturing a 70-mile long stretch of the fault. However, the folds observed on sedimentary rocks near the fault zone are overturned folds and steeper. Movement along this thrust raised a ridge of Jurassic and Cretaceous m, A 1200 km-long transform plate boundary passes through southeastern Alaska and northwestern British Columbia and represents one of the most seismically active, but poorly understood continental margins of North America. It is often referred to as the right lateral strike-slip equivalent to the San Andreas fault zone. United States, 4210 University Drive - AAPG Bulletin (American Association of Petroleum Geologists); (USA). The Queen Charlotte Fault (QCF) is a transform fault that separates the Pacific plate and the North American plate. Clearly evident in the imagery are the deformation of sediments at the base of the slope, the surface expression of seismically active faults, the mass wasting of sediment frequently observed at the base of the slope, and the erosional, The Queen Charlotte basin is a 40,000 km{sup 2} late Paleogene-Neogene basin underlying the Queen Charlotte Islands, Hecate Strait, and Queen Charlotte Sound region of the Canadian Pacific continental margin. The Queen Charlotte fault marks the boundary between two tectonic plates: the Pacific Plate to the southwest, and the North American Plate to the northeast. For example, the mountain experienced a small swarm of . The Queen loved the residence so much, she started spending most of her time there, and it became known as The Queens House.. In 2015, U.S. Geological Survey scientists in collaboration with scientists from other institutions began a study of the Queen Charlotte faultthe first systematic study of the fault in more than three decades. 834 Lincoln Street [8] The Queen Charlotte Fault continues northward along the Alaskan coast where it is called the Fairweather Fault. The Queen Charlotte fault became the western terminus of the glacio-isostatic forebulge, with the fault acting as a hinged flap taking up the uplift and collapse along the fault of 70+ m. This may have resulted in the development of the distinctive fault valley that presently acts as a very linear channel pathway for sediment throughout the . [32] Recent detailed seafloor mapping has revealed the expression of the Queen Charlotte Fault on the seafloor,[33] including the truncation of submarine canyons that occur along the continental slope.[34]. On Sunday, 22 debutantes made their London society debut at Queen Charlotte's Ball. Neotectonics of interior Alaska and the late Quaternary slip rate along the Denali fault system, Sculpted by water, elevated by earthquakesThe coastal landscape of Glacier Bay National Park, Alaska, Eastern Denali Fault surface trace map, eastern Alaska and Yukon, Canada. Charlotte was also the mother of two future British monarchs, George IV and William IV. 384 Woods Hole Road Quissett Campus Woods Hole, MA 02543-1598 In 2015, U.S. Geological Survey scientists in collaboration with scientists from other institutions began a study of the Queen Charlotte faultthe first systematic study of the fault in more than three decades. The junction of the Queen Charlotte, Fairweather, and Transition faults is located at the southeastern tip of the Yakutat block, an oceanic plateau and microplate. Creating a 700 mile boundary between the Pacific and NorthAmerican tectonic plates, the fault has been described as the San Andreas of the north based on its characteristic horizontal motion (i.e., strike-slip faulting) and its frequent earthquakes. "Queen Charlotte has been such a moving character to write and now having the opportunity to work with Julia to adapt this story into a book is such an exciting opportunity," Rhimes said in a . In the core of the orogen,250 km from the transform, north striking, dipslip brittle faults and vertical axis rotation of large crustal domains occurred after 50 Ma and before intrusion of mafic dikes at 20 Ma. [4] It sustains the highest known deformation rates among continental or continent-ocean transform systems globally, accommodating greater than 50mm/yr dextral offset. According to A.Sutherland Browns article Geology of the Queen Charlotte Islands, folds with low intensity are observable near the junction of the Pacific and North America plates. Queen Charlotte and the Prince of Wales would reconcile in 1791, and when she died in 1818, sitting in an armchair at the familys country retreat, her eldest son was there beside her, holding her hand. The purpose of the proposed study is to characterize an approximately 450-km segment of the fault that encompasses systematic variations in key parameters in space and time: (1) Changes in fault obliquity relative to Pacific-North American plate motion leading to increased convergence from north to south; (2) Pacific plate age and theoretical To the south, the San Andreas blends into a series of faults, like the San Jacinto Fault, and it . San Andreas, Alpine) in terms of slip rates and seismogenic potential. Brub, J., G. C. Rogers, R. M. Ellis, and F. O. Hasselgren (1989). (Earthquake). Later, Mozart would dedicate his Opus 3 piece to the Queen. Seismol. Geomorphologic expression and surface processes associated with the QCFZ system have been revealed in unprecedented detail by recent seabed mapping surveys. Secure .gov websites use HTTPS Prince Louis and Princess Charlotte's duties for the Coronation have been made public as George takes center stageOn May 6, King Charles will be crowned, and. The Queen Charlotte Fault is an active transform fault that marks the boundary of the North American and the Pacific Plates. Subduction Zone: A region where the earth's plates collide, with one plate sliding beneath the other. The Sitka Sound Science Center is part of an international team of scientistsprobing the depths of the northeast Pacific offshore of Alaska and British Columbia, Canada, to better understand hazards associated with the Queen Charlotte Fault. Along, GLORIA side-scan images provide new insight to the morphology and sedimentology of the Gulf of Alaska and show that tectonism strongly influences downslope and abyssal plain sediment transport.
