2001, Report
Information is a resource that can help Native American governments and their people. The U.S. Geological Survey (USGS) makes available technical expertise, reports, and other impartial information sources that can benefit Native Americans interested in subsistence issues, water, land use, and the health of many parts of the environment.The USGS...
Catalog of earthquake hypocenters at Alaskan volcanoes: January 1, 1994 through December 31, 1999

2001, Open-File Report 2001-189
The Alaska Volcano Observatory (AVO), a cooperative program of the U.S. Geological Survey, the Geophysical Institute of the University of Alaska - Fairbanks, and the Alaska Division of Geological and Geophysical Surveys, has maintained a seismic monitoring program at potentially active volcanoes in Alaska since 1988 (Power and others, 1993;...
Effects of food stress on survival and reproductive performance of seabirds
John F. Piatt, Sasha Kitaysky
2001, Report
Traditional field methods of assessing effects of fluctuations in food supply on the survival and reproductive performance of seabirds may give equivocal results. In this project we applied an additional tool: The measure of stress hormones in free-ranging seabirds. Food stress can be quantified by measuring base levels of stress...
USGS Mineral Resources Program; national maps and datasets for research and land planning

2001, Fact Sheet 079-01
The U.S. Geological Survey, the Nation’s leader in producing and maintaining earth science data, serves as an advisor to Congress, the Department of the Interior, and many other Federal and State agencies. Nationwide datasets that are easily available and of high quality are critical for addressing a wide range of...
Volcanism in national parks: summary of the workshop convened by the U.S. Geological Survey and National Park Service, 26-29 September 2000, Redding, California
Steven R. Brantley, Lindsay McClelland
Marianne Guffanti, editor(s)
2001, Open-File Report 2001-435
Spectacular volcanic scenery and features were the inspiration for creating many of our national parks and monuments and continue to enhance the visitor experience today (Table 1). At the same time, several of these parks include active and potentially active volcanoes that could pose serious hazards - earthquakes, mudflows, and...

Frolov, Kazuya Fujita, Nikolai A. Goryachev, Anany I. Pozdeev, Vladimir V. Ratkin, Sergey M. Rodinov, Ilya S. Rozenblum, David W. Scholl, Vladimir I. Shpikerman, Anatoly A. Sidorov, David B. Stone
2001, Open-File Report 2001-261
The digital files on this report consist of a dynamic computer model of the metallogenesis and tectonics of the Circum-North Pacific, and background articles, figures, and maps. The tectonic part of the dynamic computer model is derived from a major analysis of the tectonic evolution of the Circum-North Pacific which...
Reprocessing of multi-channel seismic-reflection data collected in the Chukchi Sea
Warren F. Agena, Myung W. Lee, Patrick E. Hart
2001, Open-File Report 2001-330
Contained on this set of two CD-ROMs are stacked and migrated multi-channel seismic-reflection data for 44 lines recorded in the Chukchi Sea, northern Alaska, by the United States Geological Survey in 1977, 1978, and 1980. All data were reprocessed by the USGS in 2000 using updated methods. The resulting final...
Water temperature of streams in the Cook Inlet basin, Alaska, and implications of climate change
Rebecca E. Kyle, Timothy P. Brabets
2001, Water-Resources Investigations Report 2001-4109
Water-temperature data from 32 sites in the Cook Inlet Basin, south-central Alaska, indicate various trends that depend on watershed characteristics. Basins with 25 percent or more of their area consisting of glaciers have the coldest water temperatures during the open-water season, mid-May to mid-October. Streams and rivers that drain lowlands...
Photogrammetric Data Set, 1957-2000, and Bathymetric Measurements for Columbia Glacier, Alaska
Robert M. Krimmel
2001, Water-Resources Investigations Report 2001-4089
Major changes in the length, speed, surface altitude, and calving rate of Columbia Glacier, Alaska have been recorded with stereo vertical photography acquired on 119 dates from 1957 to 2000. Photogrammetric analysis of this photographic record has resulted in precise measurement of these changes. From 1982 to 2000 Columbia Glacier...
Geologic map of the Arctic Quadrangle, Alaska
W. P. Brosge, H. N. Reiser, J.T. Dutro Jr., R. L. Detterman, I.L. Tailleur
2001, IMAP 2673
Introduction The Arctic quadrangle is well located to shed light on the basic geologic relations of northern Alaska. The rocks represent all of the stratigraphic systems from Cambrian to Cretaceous and all but one of the tectono-stratigraphic subterranes of the Brooks Range, from the autochthonous subterrane in the north to...
Geologic studies in Alaska by the U.S. Geological Survey, 1999
Larry P. Gough, Frederic H. Wilson, editor(s)
2001, Professional Paper 1633
The collection of nine papers that follow continue the series of U.S. Geological Survey (USGS) investigative reports in Alaska under the broad umbrella of the geologic sciences. The series presents new and sometimes preliminary findings that are of interest to earth scientists in academia, government, and industry; to land and...
Arctic National Wildlife Refuge, 1002 area, petroleum assessment, 1998, including economic analysis
K. J. Bird, D.W. Houseknecht
2001, Fact Sheet 028-01
The Alaska National Interest Lands Conservation Act (1980) established the Arctic National Wildlife Refuge (ANWR). In section 1002 of that act, Congress deferred a decision regarding future management of the 1.5-million-acre coastal plain ("1002 area") in recognition of the area’s potentially enormous oil and gas resources and its importance...

K. J. Bird
2001, Fact Sheet 024-01
The area currently known as the National Petroleum ReserveAlaska was originally designated in 1923 as Naval Petroleum Reserve No. 4 (NPR4). It was one of four U.S. regions thought to contain significant amounts of oil that were to be reserved for national crises. Geographic and geologic knowledge of the NPR4...

A. D. McGuire, S. Sitch, Joy S. Clein, R. Dargaville, G. Esser, J. Foley, Martin Heimann, F. Joos, J. Kaplan, D. W. Kicklighter, R.A. Meier, J. M. Melillo, B. Moore III, I. C. Prentice, N. Ramankutty, T. Reichenau, A. Schloss, H. Tian, L.J. Williams, U. Wittenberg
2001, Global Biogeochemical Cycles (15) 183-206
The concurrent effects of increasing atmospheric CO2 concentration, climate variability, and cropland establishment and abandonment on terrestrial carbon storage between 1920 and 1992 were assessed using a standard simulation protocol with four process-based terrestrial biosphere models. Over the long-term(1920–1992), the simulations yielded a time history of terrestrial uptake that is...
Observations of earthquake source parameters at 2 km depth in the Long Valley Caldera, eastern California
Stephanie G. Prejean, William L. Ellsworth
2001, Bulletin of the Seismological Society of America (91) 165-177
To investigate seismic source parameter scaling and seismic efficiency in the Long Valley caldera, California, we measured source parameters for 41 earthquakes (M 0.5 to M 5) recorded at 2 km depth in the Long Valley Exploratory Well. Borehole recordings provide a wide frequency bandwidth, typically 1 to 200–300 Hz,...

Water Resources Division, U.S. Geological Survey
2001, Report
The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000 scale and exists at that scale for the whole country. High resolution NHD adds...
