At the same time, several of these parks include active and potentially active volcanoes that could pose serious hazards - earthquakes, mudflows, and hydrothermal explosions, as well as eruptions - events that would profoundly affect park visitors, employees, and infrastructure. Although most parks are in relatively remote areas, those with high visitation have daily populations during the peak season equivalent to those of moderate-sized cities. For example, Yellowstone and Grand Teton national parks can have a combined daily population of 80,000 during the summer, with total annual visitation of 7 million. Nearly 3 million people enter Hawai`i Volcanoes National Park every year, where the on-going (since 1983) eruption of Kilauea presents the challenge of keeping visitors out of harm's way while still allowing them to enjoy the volcano's spellbinding activity.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01435","usgsCitation":"Brantley, S., and McClelland, L., 2001, Volcanism in national parks: summary of the workshop convened by the U.S. Geological Survey and National Park Service, 26-29 September 2000, Redding, California: U.S. Geological Survey Open-File Report 2001-435, Report: PDF, 43 p.; Report: HTML Document, https://doi.org/10.3133/ofr01435.","productDescription":"Report: PDF, 43 p.; Report: HTML Document","numberOfPages":"43","additionalOnlineFiles":"Y","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":282915,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3002,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0435/","linkFileType":{"id":5,"text":"html"}},{"id":59754,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0435/pdf/of01-435.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":282914,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0435/ofr01-435_report.html"}],"country":"United States","state":"Alaska;California;Hawai'i;Oregon;Washington;Wyoming","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 172.45,32.37 ], [ 172.45,71.39 ], [ -103.89,71.39 ], [ -103.89,32.37 ], [ 172.45,32.37 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd7e5","contributors":{"editors":[{"text":"Guffanti, Marianne","contributorId":55334,"corporation":false,"usgs":true,"family":"Guffanti","given":"Marianne","affiliations":[],"preferred":false,"id":745714,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Brantley, Steven R. srbrant@usgs.gov","contributorId":4182,"corporation":false,"usgs":true,"family":"Brantley","given":"Steven R.","email":"srbrant@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":205750,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McClelland, Lindsay","contributorId":51652,"corporation":false,"usgs":true,"family":"McClelland","given":"Lindsay","email":"","affiliations":[],"preferred":false,"id":205751,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":31225,"text":"ofr0161 -

Salinity remained polyhaline to\r\neuhaline throughout the time of deposition (1800-1997), with alternating periods of\r\nstability and increased fluctuations. Since 1800, a Brachidontes assemblage has\r\ncharacterized Whipray Basin and the dominant faunal components have remained the\r\nsame in terms of presence and absence of species. However, patterns of dominance and\r\ndiversity within the Brachidontes assemblage have changed and these changes indicate\r\nfluctuations in the environment.\r\nThe period from 1815 to 1857 was distinguished by an abundance of molluscs\r\ndwelling on seagrass and sub-aquatic vegetation.

The period from 1862 to 1894\r\nappears unstable based on fluctuations in molluscan faunal richness, abundance, and\r\ndominant species. The epiphytic molluscs experienced significant shifts (? >30%)\r\nassociated with changes in sub-aquatic vegetation. The changes in epiphytic molluscs\r\nfrom 1871 to 1913 may be indicative of a seagrass die-off.

Fluctuating salinity, changes in\r\nvegetation, and reduced water quality (low O2, increased nutrients and/or reduced clarity)\r\noxygen supply) have characterized the past 50 years. These changes preceded a seagrass\r\ndie-off in 1987-88 and may be related to the causes of the die-off.

Statistical comparison of modern molluscan fauna to down-core molluscan assemblages in four cores elucidates changes in the Florida Bay ecosystem during the past 100 to 200 years. Fluctuations within molluscan faunal dominance and diversity patterns suggest a response to changing environmental conditions. Faunal dominance patterns indicate an increase in salinity in the northern transitional zone, and possibly the eastern portion of Florida Bay. Distinctive faunal shifts recorded at Russell Bank occur approximately between 1913 and 1933 and at Bob Allen mudbank between approximately 1900 and 1910. The period from approximately 1930 to 1980 within these cores shows rapid and dramatic fluctuations in species dominance and faunal richness. Beginning around 1980, the mussel Brachidontes exustus, which can tolerate diminished water quality and a wide range of salinities, increases in percent abundance in the upper portion of all four cores and becomes the dominant species at Russell Bank and Bob Allen Mudbank.
While these fluctuations within assemblages are distinctive, they are not so profound that they represent a major shift in estuarine zonations within northern, eastern, and central Florida Bay during the past 100 to 200 years. The majority of the molluscan fauna that are present at the core sites today are generally present throughout the period of deposition. Fluctuations in the molluscan faunal record down-core primarily express changes in dominance and diversity within assemblages and do not reflect substantial changes in overall assemblages. It is these fluctuations in dominance and the appearance or disappearance of critical indicator species that are indicative of salinity changes.
Understanding the dynamics of an ecosystem and the natural range of variation in the system over an extended period of time is a critical component of effective restoration. Analysis of the modern environment provides a means to interpret biological data preserved in cores, and to determine the physical and chemical variations in the environment indicated by the biota. Knowledge of the past provides the best insight to predicting the impact of future change on the environment.

These predictions stemmed from observations that the Pacific Decadal Oscillation (PDO) appeared to abruptly change from a “positive” to a “negative” phase in 1999 (Figure 1). During the mid‐twentieth century, a similar negative phase of the PDO was accompanied by prolonged dry conditions in the southwest.
By extrapolation, some climatologists predicted future drought in the southwest. Such a change would heavily affect land use planning in the region, because national demographics have stressed the region's resources over the past century From 1990 to 2000, for instance, the population of Nevada and Arizona increased by almost 2.3 million people (http://www.census.gov/population/www/cen2000/respop.html). To discuss potential scenarios of landscape and ecosystem response to 25 years of hot and dry climate, scientists from diverse disciplines gathered at the University of Arizona in April 2001.

Magnetic samples were taken from three stratigraphic sections spanning the entire formation: the type section of the Twobar Shale and Rices Mudstone members of the San Lorenzo Formation at Kings Creek, the thickest section along the San Lorenzo River, and the upper part of the section along Zayante Creek. After overprinting was removed, a stable remanence was obtained which passed a reversal test and fold test. Our results suggest an age of 36.5 Ma for the early/late Narizian boundary, 35.5 Ma for the Narizian/Refugian boundary, 32.5 Ma for the Refugian/Zemorrian boundary, and 30.0 Ma for the early/late Zemorrian boundary, consistent with results reported from other regions. However, the beginning of the Vaqueros Stage is demonstrably time transgressive, with typical Vaqueros molluscs (e.g., Turritella inezana) first occurring as early as 29.5 Ma in the Santa Cruz Mountains, while they first occur at 27.5 Ma in Ventura County, and 17.5 Ma in Orange County, California.

Magnetic samples were taken from the 75 m of exposed section, and yielded a stable remanence held mainly in magnetite which passed a reversal test. The section showed two normal zones and three reversed magnetozones. Based on calcareous nannofossils and planktonic foraminifera, we correlate the type Ulatisian with Chron C20r-C22r (45.0-50.5 Ma), which is latest early Eocene to early middle Eocene on the global time scale. Our data calibrate what has been previously suggested by micropaleontologists: the base of the Ulatisian in the Vacaville Shale is 2 million years older (50.5 Ma) than it is in Media Agua Creek in the Temblor Range (48.5 Ma), and that the top of the Ulatisian is a million years younger (46.5 Ma) in the Vacaville section then it is at Media Agua Creek (47.5 Ma). This is another example of the problems with time-transgressive benthic foraminiferal stages.

Together they form the broad transform-fault boundary along which the Pacific and North America crustal plates move irregularly past one another in a right-lateral sense at a rate of about 5 centimeters (cm)/year. The city of San Diego, which lies adjacent to the Pacific Ocean in the southwestern-most corner of California, is cut by one such fault zone -- the Rose Canyon Fault Zone. Oblique movement on faults within the Rose Canyon Fault Zone has, over time, led to the development of San Diego Bay, which separates the metropolitan area of San Diego from Coronado and North Island. The Coronado Bridge spans San Diego Bay and connects the cities of San Diego and Coronado. A principal concern regarding the bridge's earthquake safety involves its proximity, especially of its foundation piers, to potential shallow fault rupture. The objectives of this study were (1) to identify and accurately locate Holocene faults (those younger than about 12,000 years) and (2) to determine the time of the most recent movement on these faults and, therefore, their potential hazard to the Coronado Bridge.

This disrupted zone is within the Fox Hills Formation, ranges from 0.5 to 5 m in thickness, and contains large-scale slump-roll structures, clastic dikes, flame structures, and massive, homogenized beds. The zone is ∼0.5 m above a belemnite fauna Sr dated as 67.6 ± 0.5 Ma, contains scaphitid ammonites characteristic of the Jeletzkytes nebrascensis ammonite zone of the Fox Hills Formation, and is capped by a 0.5–4-cm-thick brownish-black mudstone that contains spherules. Pollen of the late Maastrichtian Wodehouseia spinata palynostratigraphic zone occurs immediately above and below the disrupted zone. The disrupted zone is overlain by an additional 25 m of marine Fox Hills Formation. These stratigraphic relationships suggest that the upper part of the Fox Hills Formation in this part of South Dakota is Paleocene; that the Western Interior Seaway was locally present well into the Paleocene; and that scaphitid ammonites may range the Cretaceous-Tertiary (K-T) boundary.

The tectonic part of the dynamic computer model is derived from a major analysis of the tectonic evolution of the Circum-North Pacific which is also contained in directory tectevol. \nThe dynamic computer model and associated materials on this CD-ROM are part of a project on the major mineral deposits, metallogenesis, and tectonics of the Russian Far East, Alaska, and the Canadian Cordillera. The project provides critical information on bedrock geology and geophysics, tectonics, major metalliferous mineral resources, metallogenic patterns, and crustal origin and evolution of mineralizing systems for this region. The major scientific goals and benefits of the project are to: (1) provide a comprehensive international data base on the mineral resources of the region that is the first, extensive knowledge available in English; (2) provide major new interpretations of the origin and crustal evolution of mineralizing systems and their host rocks, thereby enabling enhanced, broad-scale tectonic reconstructions and interpretations; and (3) promote trade and scientific and technical exchanges between North America and Eastern Asia.","language":"ENGLISH","doi":"10.3133/ofr01261","collaboration":"See also Professional Paper PP-1626","usgsCitation":"Scotese, C.R., Nokleberg, W.J., Monger, J.W., Norton, I.O., Parfenov, L.M.,

The potential for development of water resources in this aquifer has prompted Federal, State, and local authorities to seek additional information about the quality and quantity of ground water in the carbonate-rock province.\r\n\r\nInvestigations of the region's hydrogeology have been ongoing since the early 1900's. U.S. Geological Survey studies dating from 1975 to 1996 used these data to identify temporal changes of water levels in wells, regional potentiometric surfaces, and the direction of regional ground-water flow in southern Nevada. In the current study, the ground-water potentiometric surface in a 20,000-square-mile section of the regional carbonate-rock aquifer in southern Nevada and southeastern California was identified based on interpretation of water-level data collected from 1998 through 2000. Also included are hydrographs that were constructed from water-level data collected from 1985 through 2000. The hydrographs and accompanying map provide a generalized picture of water levels in consolidated rocks of the southern portion of the carbonate-rock province. Interpretation of the potentiometric surface was constrained by the limited number of wells completed in the carbonate-rock aquifer.","language":"ENGLISH","doi":"10.3133/ofr01335","usgsCitation":"Wilson, J., 2001, Potentiometric surface, carbonate-rock province, southern Nevada and southeastern California, 1998-2000: U.S. Geological Survey Open-File Report 2001-335, 15 p., 1 over-size sheet. , https://doi.org/10.3133/ofr01335.","productDescription":"15 p., 1 over-size sheet.

The well was drilled in cooperation with the State Department of Hawaiian Home Lands and the Maui County Department of Water Supply, and is located near the area that supplies much of the drinking water on Molokai. The well is at a ground-surface elevation of about 982 feet and penetrated a 1,585-foot section of soil and volcanic rock to a depth of 603 feet below sea level. Prior to casing, a cave-in caused the bottom 55 feet of the well to be filled with rocks originating from a zone above. Thus, the final well depth reported by the driller was 1,530 feet.\r\n\r\nMeasured water levels in the well during the period from February 1 to July 13, 2001 range from 8.68 to 9.05 feet above sea level. The most recent available water-conductivity profile from July 13, 2001 indicates that the lowest salinity water in the well is in the upper zone from the water table to a depth of about 220 feet below sea level. Below this upper zone, water salinity increases with depth. The water-temperature profile from July 13, 2001 indicates that the lowest temperature water (20.2 degrees Celsius) in the well is located in the upper zone from the water table to a depth of about 200 feet below sea level. Water temperature increases to 24.5 degrees Celsius near the bottom of the measured profile, 507 feet below sea level.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr2001350","collaboration":"Prepared in cooperation with the State of Hawaii Department of Hawaiian Home Lands and Maui County Department of Water Supply","usgsCitation":"Oki, D.S., and Bauer, G.R., 2001, Drilling, Construction, Water-Level, and Water-Quality Information for the Kualapuu Deep Monitor Well, 4-0800-01, Molokai, Hawaii: U.S. Geological Survey Open-File Report 2001-350, iv, 19 p. , https://doi.org/10.3133/ofr2001350.","productDescription":"iv, 19 p.
