1999 Volcanic activity in Alaska and Kamchatka: Summary of events and response of the Alaska Volcano Observatory
Robert G. McGimsey, Christina A. Neal, Olga Girina
2004, Open-File Report 2004-1033
The Alaska Volcano Observatory (AVO) monitors 41 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on daily analysis of satellite images, pilot reports, and observations of local residents and ship's crews. In 1999, AVO responded to eruptive...

Evaluation of pier-scour equations for coarse-bed streams
Katherine J. Chase, Stephen R. Holnbeck
2004, Scientific Investigations Report 2004-5111
Streambed scour at bridge piers is among the leading causes of bridge failure in the United States. Several pier-scour equations have been developed to calculate potential scour depths at existing and proposed bridges. Because many pier-scour equations are based on data from laboratory flumes and from cohesionless silt- and sand-bottomed...

Status assessment and conservation plan for the yellow-billed loon (Gavia adamsii)
Susan L. Earnst
2004, Scientific Investigations Report 2004-5258
Because of its restricted range, small population size, specific habitat requirements, and perceived threats to its breeding habitat, the Yellow-billed Loon (Gavia adamsii) is a species of conservation concern to the U.S. Fish and Wildlife Service and the subject of a petition for listing under the Endangered Species Act. This...

Origin of the Bering Sea salient
J.M. Amato, J. Toro, Thomas E. Moore
2004, GSA Special Papers (383) 131-144
Our investigations in Alaska and Russia show that the curved orogen of the Bering Strait region is a composite feature that formed as a result of multiple superimposed events and cannot be related to latest Cretaceous–early Tertiary east-west shortening. Relations interpreted to record east-west shortening include the Chukchi syntaxis, deformation...
Testing archival tag technology in coho salmon
Jennifer L. Nielsen, Philip Richards, Thor Tingey, Derek Wilson, Christian E. Zimmerman
2004, Report
Archive tags with temperature and light-geolocation sensors will be monitored for post-smolt coho salmon in Cook Inlet. Light/location relationships specific to the Gulf of Alaska developed under Project 00478 will be applied in this study of movement and migration paths for coho salmon during maturation in ocean environments in Cook...
Using Forward Looking Infrared (FLIR) imagery to detect polar bear maternal dens: Operations manual
Geoffrey S. York, Steven C. Amstrup, Kristin S. Simac
2004, BOEM MMS 2004-062
Recent research has shown that Forward Looking Infia-Red (FLIR) imagery can detect polar bear dens despite total snow cover over their deming habitat. FLIR imagers detect a AT or difference in temperature between objects in the imager's field of view. During the Arctic winter, the groundlsnow surface is typically cold,...
Seafloor habitat mapping and classification in Glacier Bay, Alaska: Phase 1 & 2 1996-2004
Philip N. Hooge, Paul R. Carlson, Jennifer Mondragon, Lisa L. Etherington, G.R. Cochran
2004, Report
Glacier Bay is a diverse fjord ecosystem with multiple sills, numerous tidewater glaciers and a highly complex oceanographic system. The Bay was completely glaciated prior to the 1700’s and subsequently experienced the fastest glacial retreat recorded in historical times. Currently, some of the highest sedimentation rates ever observed occur in...
Mitigation of earthquake damage
George Plafker
2004, Book chapter, Meeting Challenges with Geologic Maps
The article describes the use of a geologic map to help mitigate earthquake damage along the Denali Fault where the Trans-Alaska Pipeline crosses. Geologic mapping of bedrock and unconsolidated deposits reveals a history of horizontal right-lateral slip and local vertical separations at the fault. It was determined that the eastern...

The Cook Inlet Basin study unit of the U.S. Geological Survey National Water-Quality Assessment Program comprises 39,325 square miles in south-central Alaska. Data were collected at eight fixed sites to provide baseline information in areas where no development has taken place, urbanization or logging have occurred, or the effects of...
Preliminary integrated geologic map databases for the United States: Minnesota, Wisconsin, Michigan, Illinois, and Indiana

2004, Open-File Report 2004-1355
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....
Simulated peak inflows for glacier dammed Russell Fiord, near Yakutat, Alaska
Edward G. Neal
2004, Scientific Investigations Report 2004-5234
In June 2002, Hubbard Glacier advanced across the entrance to 35-mile-long Russell Fiord creating a glacier-dammed lake. After closure of the ice and moraine dam, runoff from mountain streams and glacial melt caused the level in ?Russell Lake? to rise until it eventually breached the dam on August 14, 2002....
Occurrence and distribution of trace elements in snow, streams, and streambed sediments, Cape Krusenstern National Monument, Alaska, 2002-2003
Timothy P. Brabets
2004, Scientific Investigations Report 2004-5229
Cape Krusenstern National Monument is located in Northwest Alaska. In 1985, an exchange of lands and interests in lands between the Northwest Alaska Native Association and the United States resulted in a 100-year transportation system easement for 19,747 acres in the monument. A road was then constructed along the easement...
