Risk assessments are needed to understand the implications of reported concentrations; a fundamental part of the...
Identifying major sedimentary basins beneath the West Antarctic ice sheet from aeromagnetic data analysis
Robin E. Bell, M. Studinger, G.D. Karner, Carol A. Finn, D. D. Blankenship
Dieter Karl Futterer, Detlef Damaske, Georg Kleinschmidt, Hubert Miller, Franz Tessensohn, editor(s)
2005, Book chapter, Antarctica: Contributions to global earth sciences
In the Ross Sea, large sedimentary basins reflect primarily the major extensional event associated with the Late Cretaceous breakup of Gondwana. Within the Interior Ross Embayment, no similar large basins have been identified to date. We have used aerogravity and Werner deconvolution methods applied to aeromagnetic data to map depth...
A retrospective perspective: evaluating population changes by repeating historic bird surveys
Lawrence D. Igl, Douglas H. Johnson
2005, General Technical Report GTR-PSW-191
Acquiring an accurate picture of the changes in bird populations often involves a tradeoff between the time and effort required to complete the surveys and the number of years spent surveying the bird populations. An alternative approach to long-term monitoring efforts is to collect current data and contrast those with...

Taking the pulse of Colorado's Front Range: Developing regional indicators of environmental and quality of life condition
Jill S. Baron
2005, Fact Sheet 2005-3021
Indicators are routinely used to report the status and trends of human health, economy, educational achievement, and quality of life. Some environmental indicators, such as for water and air quality, are routinely reported and used to inform personal, management, or policy decisions. Other environmental indicators, particularly those that do not...

Heather Best, J. P. McNamara, Lee M. Liberty
2005, Arctic, Antarctic, and Alpine Research (37) 162
We collected ground-penetrating radar data at 10 sites along the Kuparuk River and its main tributary, the Toolik River, to detect unfrozen water beneath river ice. We used 250 MHz and 500 MHz antennas to image both the ice-water interface and the river channel in late April 2001, when daily...
Measuring nighttime spawning behavior of chum salmon using a dual-frequency identification sonar (DIDSON)
K.F. Tiffan, D.W. Rondorf
2005, Conference Paper
The striking body coloration and morphology that Pacific salmon display during spawning coupled with elaborate courtship behaviors suggest that visual cues are important during their reproductive period. To date, virtually all existing information on chum salmon (Oncorhynchus keta) spawning behavior has been derived from studies conducted during the daytime, and...
Diseases of amphibian eggs and embryos
D. E. Green, K. A. Converse
S.K. Majumdar, J.E. Huffman, F.J. Brenner, A.I. Panah, editor(s)
2005, Book chapter, Wildlife Diseases: Landscape Epidemiology, Spatial Distribution and Utilization of Remote Sensing Technology.
Amphibians generally are prolific egg producers. In tropical and semi-tropical regions, deposition of eggs may occur year-round or may coincide with rainy seasons, while in temperate regions, deposition of eggs usually occurs immediately after emergence from hibernation. Numbers of eggs produced by each species may vary from a few dozen...
Optimal swim speeds for traversing velocity barriers: An analysis of volitional high-speed swimming behavior of migratory fishes
T. Castro-Santos
2005, Journal of Experimental Biology (208) 421-432
Migrating fish traversing velocity barriers are often forced to swim at speeds greater than their maximum sustained speed (Ums). Failure to select an appropriate swim speed under these conditions can prevent fish from successfully negotiating otherwise passable barriers. I propose a new model of a distance-maximizing strategy for fishes traversing...
