Seismic-hazard maps for Alaska and the Aleutian Islands
Robert L. Wesson, Arthur D. Frankel, Charles S. Mueller, Stephen C. Harmsen
1999, IMAP 2679
Probabilistic seismic hazard maps were prepared for Alaska portraying peak horizontal ground acceleration and horizontal spectral response acceleration for 0.2, 0.3, and 1.0 second periods with probabilities of exceedance of 10% in 50 years and 2% in 50 years. This particular data set...
Geographic information systems (GIS) compilation of geophysical, geologic, and tectonic data for the circum-North Pacific
Mark L. Greninger, Simon L. Klemperer, Warren J. Nokleberg
1999, Open-File Report 99-422
The accompanying directory structure contains a Geographic Information Systems (GIS) compilation of geophysical, geological, and tectonic data for the Circum-North Pacific. This area includes the Russian Far East, Alaska, the Canadian Cordillera, linking continental shelves, and adjacent oceans. This GIS compilation extends from 120°E to 115°W, and from 40°N to...
Geologic map of the Seldovia quadrangle, south-central Alaska
Dwight Bradley, Timothy M. Kusky, Peter J. Haeussler, Susan M. Karl, D. Thomas Donley
1999, Open-File Report 99-18
This is a 1:250,000-scale map of the bedrock geology of the Seldovia quadrangle, south-central Alaska. The map area covers the southwestern end of the Kenai Peninsula, including the Kenai Lowlands and Kenai Mountains, on either side of Kachemak Bay. The waters of Cook Inlet cover roughly half of the map...
An interpretation of the aeromagnetic and gravity data and derivative maps of the Craig and Dixon Entrance 1°x 3° quadrangles and the western edges of the Ketchikan and Prince Rupert quadrangles, southeastern Alaska
Jeffrey C. Wynn, R.P. Kucks, D. J. Grybeck
1999, Data Series 56
The U.S. Geological Survey (USGS) is required by the Alaska National Interest Lands Conservation Act (ANILCA, Public Law 96-487) to survey certain Federal lands to determine their mineral resource potential. As part of continuing studies designed to fulfill this responsibility, geochemical, geological and geophysical surveys of the Craig and Dixon...
Preliminary volcano-hazard assessment for Iliamna Volcano, Alaska
Christopher F. Waythomas, Thomas P. Miller
1999, Open-File Report 99-373
Iliamna Volcano is a 3,053-meter-high, ice- and snow-covered stratovolcano in the southwestern Cook Inlet region about 225 kilometers southwest of Anchorage and about 100 kilometers northwest of Homer. Historical eruptions of Iliamna Volcano have not been positively documented; however, the volcano regularly emits steam and gas, and small, shallow earthquakes...
Geochemical data for environmental studies of mineral deposits at Nabesna, Kennecott, Orange Hill, Bond Creek, Bremner, and Gold Hill, Wrangell-St. Elias National Park and Preserve, Alaska
R. G. Eppinger, Paul H. Briggs, D. S. Rosenkrans, Vanessa Ballestrazze, Jose Aldir, Z. A. Brown, J.G. Crock, W. M. d’Angelo, M. W. Doughten, D.L. Fey, P. L. Hageman, R.T. Hopkins, R. J. Knight, M.J. Malcolm, J. B. McHugh, A. L. Meier, J. M. Motooka, R. M. O’Leary, B. H. Roushey, S.J. Sultley, P. M. Theodorakos, S. A. Wilson
1999, Open-File Report 99-342
Environmental geochemical investigations were carried out between 1994 and 1997 in Wrangell-St. Elias National Park and Preserve (WRST), Alaska. Mineralized areas studied include the historic Nabesna gold mine/mill and surrounding areas; the historic Kennecott copper mill area and nearby Bonanza, Erie, Glacier, and Jumbo mines; the historic mill and gold...
The needs of salmon and steelhead in balancing their conservation and use
Carl V. Burger
E. Eric Knudsen, Cleveland R. Steward, Donald D. MacDonald, Jack E. Williams, Dudley W. Reiser, editor(s)
1999, Book chapter, Sustainable fisheries management: Pacific salmon
Over the past 100 years, Pacific salmon Oncorhynchus spp. and steelhead trout O. mykiss populations in the Pacific Northwest have experienced dramatic declines as a result of human population growth and associated development of the region's natural resources. Any strategy to reverse those declines will depend on achieving consensus among...
Biological effects of the 1997/98 ENSO in Cook Inlet, Alaska
John F. Piatt, Gary S. Drew, Thomas I. van Pelt, Alisa A. Abookire, April Nielsen, Michael T. Shultz, Alexander S. Kitaysky
1999, Conference Paper, Proceedings of the 1998 Symposium on the Impacts of the 1997/98 El Niño Event on the North Pacific Ocean and Its Marginal Seas
We have been conducting detailed studies of the biology of seabirds in relation to oceanography and forage fish ecology in lower Cook Inlet, Alaska, since 1995. This fortuitously allowed us to document biological effects of the 1997/98 ENSO in this region. Anomalously warm sea surface temperatures (SSTs) were observed in...
Development of a long-term ecological monitoring program in Denali National Park and Preserve, Alaska (USA)
Karen L. Oakley, Edward M. Debevec, Eric A. Rexstad
1999, Conference Paper, Proceedings: North American science symposium: Toward a unified framework for inventorying and monitoring forest ecosystem resources
A Long-term Ecological Monitoring (LTEM) program began at Denali National Park and Preserve, Alaska (USA) in 1992, as a prototype for subarctic parks. The early history of the Denali LTEM program provides insight into the challenges that can arise during monitoring program development. The Denali program has thus far taken...
