Review of the geology and paleontology of the Ellsworth Mountains, Antarctica
G.F. Webers, J.F. Splettstoesser
2007, Open-File Report 2007-1047-SRP-107
The geology of the Ellsworth Mountains has become known in detail only within the past 40-45 years, and the wealth of paleontologic information within the past 25 years. The mountains are an anomaly, structurally speaking, occurring at right angles to the Transantarctic Mountains, implying a crustal plate rotation to reach...

Sediment and sediment-associated contaminant transport through karst
Barbara Mahler, J.-C. Personne, F. Leo Lynch, Peter C. Van Metre
2007, Book chapter, Studies of cave sediments: Physical and chemical records of paleoclimate
The unusual characteristics of subterranean flow in karst aquifers allow for the transport of sediment. Kartst ground-water system are created by dissolution of the bedrock matrix coupled with structural and stratigraphic controls. As a result, high flow velocities, large-diameter openings, and turbulent flow, all necessary for the entrainment and transport...

A pan-Precambrian link between deglaciation and environmental oxidation
T.J. Raub, J.L. Kirschvink
2007, Open-File Report 2007-1047-KP-08
Despite a continuous increase in solar luminosity to the present, Earth’s glacial record appears to become more frequent, though less severe, over geological time. At least two of the three major Precambrian glacial intervals were exceptionally intense, with solid evidence for widespread sea ice on or near the equator, well...
Jurassic silicic volcanism in the Transantarctic Mountains: Was it related to plate margin processes or to Ferrar magmatism?
D.H. Elliot, T.H. Fleming, K.A. Foland, C.M. Fanning
2007, Open-File Report 2007-1047-SRP-051
Silicic volcanism in the Transantarctic Mountains, represented by rhyolitic tuff that mainly precedes emplacement of the Ferrar Large Igneous Province, is important in interpretation of the tectonic evolution of the Antarctic sector of Gondwana. Sr and Nd isotope data indicate that the tuffs are not directly related to Ferrar magmatism...
Statistical methods for paleovector analysis
Jeffrey J. Love
2007, Book chapter, Encyclopedia of geomagnetism and paleomagnetism
Our concern is with the statistical description of paleomagnetic vectors and the estimation of their mean and variance. These vectors may come from a number of different rock units or archeological samples, representing a range of acquisition times, and be useful for studies of the mean paleomagnetic field and <i class="EmphasisTypeItalic...
Integration of seafloor point data in usSEABED
Jane A. Reid, S. Jeffress Williams, Mark Zimmermann, Chris Jenkins, Nadine E. Golden
2007, Conference Paper, Proceedings of Coastal Zone '07
Sediments of the beach, nearshore, and continental shelves record a complex interplay of processes including wave energy and direction , currents, beach erosion or accretion, bluff or cliff retreat, fluvial input, sediment longshore and cross-shelf transport processes, contaminant content and transport, sediment sources and sinks, and others. In turn, sediments...
Principal component analysis in paleomagnetism
Jeffrey J. Love
2007, Book chapter, Encyclopedia of geomagnetism and paleomagnetism
When studying the mean and variance of paleomagnetic data it is a common practice to employ principal component analysis (Jolliffe, 2002). The theory of this method is related to the mathematics quantifying the moment of inertia of a set of particles of mass about some reference point of interest. For...
Observatories, program in USA
Jeffrey J. Love, J.B. Townshend
2007, Book chapter, Encyclopedia of geomagnetism and paleomagnetism
The Geomagnetism Program of the US Geological Survey has, for over a century now, monitored the Earth's magnetic field through a network of magnetic observatories and conducted scientific analysis on the data collected. The program traces its origins to the Reorganization Act of 1843, in which Congress authorized the creation...
Cretaceous and Tertiary extension throughout the Ross Sea, Antarctica
Robert C. Decesari, Douglas C. Wilson, Bruce P. Luyendyk, Michael Faulkner
2007, Open-File Report 2007-1047-SRP-098
Marine geophysical data from the deep sea adjacent to the Ross Sea, Antarctica suggest that 70 km of extension occurred between East and West Antarctica from 46 to 2 Ma. The Northern and Victoria Land Basins in the western Ross Sea adjacent to the Transantarctic Mountains accommodated 95 km of...
Magnetic indices
Jeffrey J. Love, K.J. Remick
2007, Book chapter, Encyclopedia of geomagnetism and paleomagnetism
Magnetic indices are simple measures of magnetic activity that occurs, typically, over periods of time of less than a few hours and which is recorded by magnetometers at ground‐based observatories (Mayaud, 1980; Rangarajan, 1989; McPherron, 1995). The variations that indices measure have their origin in the Earth's ionosphere and magnetosphere....

More than 500,000 line-km of new airborne and shipborne data, recently acquired by the international community over East Antarctica and surrounding regions, significantly upgrade the Antarctic Digital Magnetic Anomaly Project (ADMAP) compilation and lead to substantial improvements in magnetic anomaly pattern recognition. New data have been matched in one inverse operation...
Coupling alongshore variations in wave energy to beach morphologic change using the SWAN wave model at Ocean Beach, San Francisco, CA
Jodi L. Eshleman, Patrick L. Barnard, Li H. Erikson, Daniel M. Hanes
2007, Conference Paper, 10th International Workshop on Wind Hindcasting and Forecasting and Coastal Hazard Symposium: North Shore, Oahu, November 11-16, 2007
Coastal managers have faced increasing pressure to manage their resources wisely over the last century as a result of heightened development and changing environmental forcing. It is crucial to understand seasonal changes in beach volume and shape in order to identify areas vulnerable to accelerated erosion. Shepard (1950) was among...
Model scenarios of shoreline change at Kaanapali Beach, Maui, Hawaii: Seasonal and extreme events
Sean Vitousek, Charles H. Fletcher, Mark A. Merrifield, Geno Pawlak, Curt D. Storlazzi
2007, Conference Paper, Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes
Kaanapali beach is a well-defined littoral cell of carbonate sand extending 2 km south from Black Rock (a basalt headland) to Hanakao'o Point. The beach experiences dynamic seasonal shoreline change forced by longshore transport from two dominant swell regimes. In summer, south swells (Hs = 1–2 m Tp = 14–25...
Pliocene environments
R.Z. Poore
2007, Book chapter, Encyclopedia of Quaternary Science
The Pliocene spans the interval of Earth history from ca. 5.3 to 1.8 million years ago (Ma). Although details are still debated there is much evidence from continental and oceanic locations indicating that conditions from 5.3 to about 3.0 Ma were often warmer than in modern times in mid- and...

2007, Conference Paper, Coastal engineering 2006: proceedings of the 30th international conference: San Diego, California, USA, 3-8 September 2006
Runup data collected during the summer of 2005 at Ocean Beach, San Francisco, CA are analyzed and considered to be typical summer swash characteristics at this site. Analysis shows that the beach was dissipative with Iribarren numbers between 0.05 and 0.4 and that infragravity energy dominated. Foreshore slopes were mild...

Uranium(VI) release from contaminated vadose zone sediments: Estimation of potential contributions from dissolution and desorption
Deborah L. Bond, James A. Davis, John M. Zachara
2007, Book chapter, Developments in earth and environmental sciences
A key difficulty in developing accurate, science-based conceptual models for remediation of contaminated field sites is the proper accounting of multiple coupled geochemical and hydrologic processes. An example of such a difficulty is the separation of desorption and dissolution processes in releasing contaminants from sediments to groundwaters; very few studies are found...

Brian J. Todd, Page C. Valentine, Oddvar Longva, John Shaw
2007, Boreas (36) 148-169
The extent and behaviour of the southeast margin of the Laurentide Ice Sheet in Atlantic Canada is of significance in the study of Late Wisconsinan ice sheet-ocean interactions. Multibeam sonar imagery of subglacial, ice-marginal and glaciomarine landforms on German Bank, Scotian Shelf, provides evidence of the pattern of glacial-dynamic events...
