Landslide triggers and types
Robert L. Schuster, Gerald F. Wieczoreck
2002, Conference Paper, Landslides
The term “landslide trigger” refers to an external stimulus, such as intense rainfall, rapid snowmelt, seismic shaking, volcanic eruption, stream/coastal erosion, or natural dam failure, which causes an immediate or near-immediate response in the form of landslide activity. In this paper, we discuss the types of landslides caused by these...
A fresh look at glacial floods
Steve M. Colman
2002, Science (296) 1251-1252
We tend to think of continental-scale ice sheets as rather ponderous affairs, inexorably advancing southward over the landscape and then slowly retreating to the north at the end of each ice age. Over the last 20 years, however, evidence has accumulated that this is a misconception. We now know that...
Design and performance of limestone drains to increase pH and remove metals from acidic mine drainage, Chapter 2
Charles A. Cravotta III,, George R. Watzlaf
2002, Book chapter, Handbook of Groundwater Remediation Using Permeable Reactive Barriers
Data on the construction characteristics and the composition of influent and effluent at 13 underground, limestone-filled drains in Pennsylvania and Maryland are reported to evaluate the design and performance of limestone drains for the attenuation of acidity and dissolved metals in acidic mine drainage. On the basis of the initial...
Sea otter (Enhydra lutris) perspective: Part B. Food limitation and the recovery of sea otters following the Exxon Valdez oil spill
Thomas A. Dean, James L. Bodkin, Allan K. Fukuyama, Stephen C. Jewett, Daniel H. Monson, Charles E. O’Clair, Glenn R. VanBlaricom
Leslie E. Holland-Bartels, editor(s)
2002, Report, Mechanisms of impact and potential recovery of nearshore vertebrate predators following the 1989 <i>Exxon Valdez</i> oil spill
We examined the potential role of food limitation in constraining recovery of sea otters in Prince William Sound, Alaska, following the <i>Exxon Valdez</i> oil spill. The spill resulted in the removal of a large number of sea otters in 1989, and as of 1998, the portion of the population in...
Harlequin duck (Histrionicus histrionicus) perspective: Harlequin duck population recovery following the Exxon Valdez oil spill: Progress, process, and constraints
Daniel Esler, Timothy D. Bowman, Kimberly A. Trust, Brenda E. Ballachey, Thomas A. Dean, Stephen C. Jewett, Charles E. O’Clair

2002, Report, Mechanisms of impact and potential recovery of nearshore vertebrate predators following the 1989 <i>Exxon Valdez</i> oil spill
Following the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, we studied the status of recovery of harlequin duck (Histrionicus histrionicus) populations during 1995-1998. We evaluated potential constraints to full recovery, including (1) exposure to residual oil, (2) food limitation, and (3) intrinsic demographic limitations on population growth...
Sea otter (Enhydra lutris) perspective: Part C. Trophic linkages among sea otters and bivalve prey in Prince William Sound, Alaska, in the aftermath of the Exxon Valdez oil spill: Implications for community models in sedimentary habitats
Glenn R. VanBlaricom, Allan K. Fukuyama, Charles E. O’Clair, Daniel H. Monson, Stephen C. Jewett, Tamara K. Gage, Thomas A. Dean, James L. Bodkin

2002, Report, Mechanisms of impact and potential recovery of nearshore vertebrate predators following the 1989 <i>Exxon Valdez</i> oil spill
We exploited the Exxon Valdez oil spill in Prince William Sound (PWS), Alaska, to evaluate effects of reduced sea otter densities on prey populations in sedimentary habitats. We considered the need for and characteristics of new models for trophic effects of sea otters on coastal marine benthic communities. We viewed...
Reducing Vulnerability of Ports and Harbors to Earthquake and Tsunami Hazards
Nathan J. Wood, James W. Good, Robert F. Goodwin
2002, Conference Paper, Coastal Disasters Conference 2002
Recent scientific research suggests the Pacific Northwest could experience catastrophic earthquakes in the near future, both from distant and local sources, posing a significant threat to coastal communities. Damage could result from numerous earthquake-related hazards, such as severe ground shaking, soil liquefaction, landslides, land subsidence/uplift, and tsunami inundation. Because of...
The global transport of dust: An intercontinental river of dust, microorganisms and toxic chemicals flows through the Earth's atmosphere
Dale Griffin, Christina Kellogg, Virginia Garrison, Eugene Shinn
2002, American Scientist (90) 228-235
The coral reefs in the Caribbean have been deteriorating since the 1970s, and no one is quite sure why. Such environmental devastation is usually blamed on Homo sapiens, but that doesn’t seem to be what’s going on here. Recently, some scientists at the USGS think they’ve solved the puzzle: Bacteria...
Synimpact-postimpact transition inside Chesapeake Bay crater
Claude (Wylie) Poag
2002, Geology (30) 995-998
The transition from synimpact to postimpact sedimentation inside Chesapeake Bay impact crater began with accumulation of fallout debris, the final synimpact deposit. Evi dence of a synimpact fallout layer at this site comes from the presence of unusual, millimeter- scale, pyrite microstructures at the top of the Exmore crater-fill breccia....
Vulnerability assessment of a port and harbor community to earthquake and tsunami hazards: Integrating technical expert and stakeholder input
Nathan J. Wood, James W. Good, Robert F. Goodwin
2002, Natural Hazards Review (3) 148-157
Research suggests that the Pacific Northwest could experience catastrophic earthquakes and tsunamis in the near future, posing a significant threat to the numerous ports and harbors along the coast. A collaborative, multiagency initiative is underway to increase the resiliency of Pacific Northwest ports and harbors to these hazards, involving Oregon...
Across-shelf sediment transport: Interactions between suspended and bed sediment
Courtney K. Harris, Patricia L. Wiberg
2002, Journal of Geophysical Research C: Oceans (107) 8-1-8-12
We use a two-dimensional, time-dependent sediment-transport model to quantify across-shelf transport, deposition, and sorting during wave-driven resuspension events characteristic of those that dominate sediment transport on many continental shelves. Decreases in wave-orbital velocities as water depth increases, and the resulting cross-shelf gradient in bed shear stress favor a net offshore...
