Micromorphologic evidence for paleosol development in the Endicott group, Siksikpuk formation, Kingak(?) shale, and Ipewik formation, western Brooks range, Alaska
Julie A. Dumoulin, Tim White
2005, Professional Paper 1709-E
Micromorphologic evidence indicates the presence of paleosols in drill-core samples from four sedimentary units in the Red Dog area, western Brooks Range. Well-developed sepic-plasmic fabrics and siderite spherules occur in claystones of the Upper Devonian through Lower Mississippian(?) Kanayut Conglomerate (Endicott Group), the Pennsylvanian through Permian Siksikpuk Formation (Etivluk Group), the...
Argon geochronology of late Pleistocene to Holocene Westdahl volcano, Unimak Island, Alaska
Andrew T. Calvert, Richard B. Moore, Robert G. McGimsey
2005, Professional Paper 1709-D
High-precision 40Ar/39Ar geochronology of selected lavas from Westdahl Volcano places time constraints on several key prehistoric eruptive phases of this large active volcano. A dike cutting old pyroclastic-flow and associated lahar deposits from a precursor volcano yields an age of 1,654+/-11 k.y., dating this precursor volcano as older than early...
Thermobarometric constraints on mid-Cretaceous to late Cretaceous metamorphic events in the western metamorphic belt of the Coast Mountains complex near Petersburg, southeastern Alaska
Glen R. Himmelberg, David A. Brew
2005, Professional Paper 1709-C
The western metamorphic belt is part of the Coast Mountains Complex of southeastern Alaska and western Canada. This complex formed as a result of mid-Cretaceous through middle Eocene crustal shortening between the previously amalgamated Wrangellia and Alexander terranes (Insular superterrane) and previously accreted terranes of the North American continental margin...
Sedimentology and sequence stratigraphy of the Cretaceous Nanushuk, Seabee, and Tuluvak formations exposed on Umiat Mountain, north-central Alaska
David W. Houseknecht, Christopher J. Schenk
2005, Professional Paper 1709-B
Upper Cretaceous strata of the upper part of the Nanushuk Formation, the Seabee Formation, and the lower part of the Tuluvak Formation are exposed along the Colville River on the east flank of Umiat Mountain in north-central Alaska. The Ninuluk sandstone, which is the uppermost unit of the Nanushuk Formation,...
2003 volcanic activity in Alaska and Kamchatka: Summary of events and response of the Alaska Volcano Observatory
Robert G. McGimsey, Christina A. Neal, Olga Girina
2005, Open-File Report 2005-1310
The Alaska Volcano Observatory (AVO) monitors the more than 40 historically active volcanoes of the Aleutian Arc. Of these, 24 were considered monitored in real time with short-period seismic instrument networks as of the end of 2003. The AVO core monitoring program also includes daily analysis of satellite imagery, observation...
Handbook of capture-recapture analysis
Steven C. Amstrup, Trent L. McDonald, Bryan F.J. Manly, editor(s)
2005, Book
Every day, biologists in parkas, raincoats, and rubber boots go into the field to capture and mark a variety of animal species. Back in the office, statisticians create analytical models for the field biologists' data. But many times, representatives of the two professions do not fully understand one another's roles....
Comparison of cytochrome P450 1A induction in blood and liver cells of sea otters
Brenda E. Ballachey, Paul W. Snyder, Tamara Kondratyuk
2005, Report
Sea otters in oiled areas of western PWS had elevated levels of cytochrome P450 1A (CYP1A), a biomarker of hydrocarbon exposure, measured in blood samples collected from otters in 1996- 98. In summer 2001, as part of project 01423, we have proposed to resample CYP1A in blood from sea otters...
Central Alaska Network vital signs monitoring plan
Margaret C. MacCluskie, Karen L. Oakley, Trent McDonald, Doug Wilder
2005, Report
Denali National Park and Preserve, Wrangell-St. Elias National Park and Preserve, and Yukon-Charley Rivers National Preserve have been organized into the Central Alaska Network (CAKN) for the purposes of carrying out ecological monitoring activities under the National Park Services’ Vital Signs Monitoring program. The Phase III Report is the initial...
Baseline water-quality characteristics of the Alaska Army National Guard Stewart River Training Area near Nome, Alaska
Josh D. Eash
2005, Scientific Investigations Report 2005-5221
The Alaska Army National Guard Stewart River Training Area is approximately 23 miles north of Nome on the Seward Peninsula in northwest Alaska. The Stewart River Training Area encompasses much of the Stewart River Basin and a small part of the Snake River Basin. Hydrologic, water-quality, and physical-habitat data were...
Bark beetle outbreaks in western North America: Causes and consequences
Barbara Bentz, Jesse Logan, James A. MacMahon, Craig D. Allen, Matt Ayres, Edward E Berg, Allan Carroll, Matt Hansen, Jeff H. Hicke, Linda A. Joyce, Wallace Macfarlane, Steve Munson, Jose Negron, Tim Paine, Jim Powell, Kenneth Raffa, Jacques Regniere, Mary Reid, Bill Romme, Steven J. Seybold, Diana Six, Jim Vandygriff, Tom Veblen, Mike White, Jeff Witcosky
2005, Conference Paper
Since 1990, native bark beetles have killed billions of trees across millions of acres of forest from Alaska to northern Mexico. Although bark beetle infestations are a regular force of natural change in forested ecosystems, several of the current outbreaks, which are occurring simultaneously across western North America, are the...
Non-lethal estimation of body composition of Yukon River salmon
F. Joseph Margraf, Kyle J. Hartman, M. Keith Cox
2005, Report
Because of the importance of Chinook salmon to commercial and subsistence fisheries on the Yukon River, further study of the factors that may affect the success of this species and our ability to manage the fisheries is warranted. Critical to these studies is the determination of the amount of lipids...
Preliminary integrated geologic map databases for the United States: Alabama, Florida, Georgia, Mississippi, North Carolina, and South Carolina
Connie L. Dicken, Suzanne W. Nicholson, John D. Horton, Michael P. Foose, Julia A. L. Mueller
2005, Open-File Report 2005-1323
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and environmental research....
