Analysis of continuous GPS measurements from southern Victoria Land, Antarctica
Michael J. Willis
2007, Open-File Report 2007-1047-SRP-064
Several years of continuous data have been collected at remote bedrock Global Positioning System (GPS) sites in southern Victoria Land, Antarctica. Annual to sub-annual variations are observed in the position time-series. An atmospheric pressure loading (APL) effect is calculated from pressure field anomalies supplied by the European Centre for Medium-Range...

2007, Technical Report 528
More than $30 million is expended annually on environmental monitoring in the Southern California Bight (SCB), yet only 5% of the Bight is monitored on an ongoing basis. Therefore, environmental managers in the SCB decided to expand their monitoring program and, starting in 1994, decided to conduct periodic regional assessments...

R. Perez-Lopez, J. L. Giner-Robles, J.J. Martinez-Diaz, M.A. Rodriguez-Pascua, M. Bejar, C. Paredes, J.M. Gonzalez-Casado
2007, Open-File Report 2007-1047-SRP-086
The tectonic field on Deception Island (South Shetlands, West Antarctica) is determined from structural and fractal analyses. Three different analyses are applied to the study of the strain and stress fields in the area: (1) field measurements of faults (strain analysis), (2) fractal geometry of the spatial distribution of lineaments...

2007, Book chapter, Subsurface hydrology: Data integration for properties and processes
Since 1997, repeated, coincident geophysical surveys and extensive hydrologic studies in shallow monitoring wells have been used to study static and dynamic processes associated with surface water-groundwater interaction at a range of spatial scales at the estuarine and ocean boundaries of an undeveloped, permeable barrier island in the Georgia part...
The history of Antarctic Peninsula glaciation
Peter F. Barker
2007, Open-File Report 2007-1047-SRP-042
As Co-Chief Scientist on DSDP Leg 35 in 1974, Cam Craddock (1930-2006) produced the first useful information on Cenozoic Antarctic Peninsula glaciation - an early middle Miocene (15-17 Ma) apparent glacial onset. Subsequent work, onshore and offshore, has greatly extended our knowledge but that early conclusion stands today. Cenozoic Antarctic...

2007, Environmental Science & Technology (41) 3408-3414
A 10-year study by the U.S. Geological Survey’s (USGS’s) National Water-Quality Assessment (NAWQA) Program provides a national-scale view of pesticide occurrence in streams and groundwater. The 1992-2001 study builds upon a preliminary analysis from NAWQA’s first phase of studies during 1992-1996 (1, 2). Pesticide data available from various studies prior...

2007, Open-File Report 2007-1047-SRP-088
Flow records at the two stream gauges on the Onyx River represent the longest actively collected environmental records in the McMurdo Dry Valleys, Antarctica. The downstream gauge, near Lake Vanda, has been collecting data since 1969, and the upstream gauge, at Lower Wright Glacier (LWRT), has collected data since 1972....

K. Gohl, G. Eagles, G. Netzeband, J.W.G. Grobys, N. Parsiegla, P. Schluter, V. Leinweber, R.D. Larter, G. Uenzelmann-Neben, G.B. Udintsev
2007, Open-File Report 2007-1047-SRP-047
The Amundsen Sea embayment of West Antarctica is in a prominent location for a series of tectonic and magmatic events from Paleozoic to Cenozoic times. Seismic, magnetic and gravity data from the embayment and Pine Island Bay (PIB) reveal the crustal thickness and some tectonic features. The Moho is 24-22 km...
Geometrical analysis of structural data collected at high South latitude: A modular arithmetic method that addresses meridional convergence
C.S. Siddoway, M.F. Siddoway
2007, Open-File Report 2007-1047-SRP-061
The convergence of meridians toward the South Pole causes unique problems for geometrical comparison of structural geological and geophysical datasets from Antarctica. The true North reference direction ordinarily is used for measuring and reporting vector data (strike, trend) in Antarctica, as elsewhere. However, over a latitude distance of just 100...
Cretaceous oblique detachment tectonics in the Fosdick Mountains, Marie Byrd Land, Antarctica
R. McFadden, C.S. Siddoway, C. Teyssier, C.M. Fanning, S.C. Kruckenberg
2007, Open-File Report 2007-1047-SRP-046
The Fosdick Mountains form an E-W trending migmatite dome in the northern Ford Ranges of Marie Byrd Land, Antarctica. Pervasively folded migmatites derived from lower Paleozoic greywacke and middle Paleozoic plutonic rocks constitute the dome. New field research documents a transition from melt-present to solid-state deformation across the south flank...
Vertical motions in Northern Victoria Land inferred from GPS: A comparison with a glacial isostatic adjustment model
F. Mancini, M. Negusini, A. Zanutta, A. Capra
2007, Open-File Report 2007-1047-SRP-073
Following the densification of GPS permanent and episodic trackers in Antarctica, geodetic observations are playing an increasing role in geodynamics research and the study of the glacial isostatic adjustment (GIA). The improvement in geodetic measurements accuracy suggests their use in constraining GIA models. It is essential to have a deeper...

2007, Journal of Island and Coastal Archaeology (2) 161-174
In this article, a collaborative effort between archaeologists and marine ecologists, we discuss the role kelp forest ecosystems may have played in facilitating the movement of maritime peoples from Asia to the Americas near the end of the Pleistocene. Growing in cool nearshore waters along rocky coastlines,...

Research to support sterile-male-release and genetic alteration techniques for sea lamprey control
Roger A. Bergstedt, Michael B. Twohey
2007, Journal of Great Lakes Research (33) 48-69
Integrated pest management of sea lampreys in the Laurentian Great Lakes has recently been enhanced by addition of a sterile-male-release program, and future developments in genetic approaches may lead to additional methods for reducing sea lamprey reproduction. We review the development, implementation, and evaluation of the sterile-male-release technique (SMRT) as...
