Bibliography of literature from 1990-1997 pertaining to Holocene and fumarolic Pleistocene volcanoes of Alaska, Canada, and the conterminous United States
Christopher J. Harpel, John W. Ewert
2000, Open-File Report 2000-17
The 1980's and 1990's were marked by frequent worldwide destructive volcanic eruptions. Significant loss of life and property during eruptions, and extensive media coverage of volcanic events around the globe have brought volcanic processes and hazards increasingly to the forefront of scientific, governmental, and public attention (e.g., Casadevall, 1994; Pringle, 1994). A result of...

2000, IMAP 2677
Introduction The Nulato quadrangle encompasses approximately 17,000 km2 (6,500 mi2) of west-central Alaska within the Yukon River drainage basin. The quadrangle straddles two major geologic features-the Yukon-Koyukuk sedimentary basin, a huge triangle-shaped Cretaceous depression that stretches across western Alaska from the Brooks Range to the Yukon delta; and the Ruby geanticline,a...

Robert G. Eppinger, Paul H. Briggs, Danny Rosenkrans, Vanessa Ballestrazze
2000, Professional Paper 1619
Environmental geochemical investigations at Wrangell-St. Elias National Park and Preserve, Alaska, between 1994 and 1997 included studies of the Kennecott stratabound copper mines and mill area; historic mines and mill in the Bremner District, gold placer mines at Gold Hill; the undisturbed porphyry, Cu-Mo deposits at Orange Hill and Bond...
US GeoData Digital Elevation Models
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 040-00
Digital elevation model (DEM) data are arrays of regularly spaced elevation values referenced horizontally either to a Universal Transverse Mercator (UTM) projection or to a geographic coordinate system. The grid cells are spaced at regular intervals along south to north profiles that are ordered from west to east. The U.S....
Revision of Primary Series Maps
Water Resources Division, U.S. Geological Survey
2000, Fact Sheet 047-00
In 1992, the U.S. Geological Survey (USGS) completed a 50-year effort to provide primary series map coverage of the United States. Many of these maps now need to be updated to reflect the construction of new roads and highways and other changes that have taken place over time. The USGS...
Organic geochemistry data of Alaska
Charles N. complied by Threlkeld, Raymond C. Obuch, G.L. Gunther
2000, Data Series 59
In order to archive the results of various petroleum geochemical analyses of the Alaska resource assessment, the USGS developed an Alaskan Organic Geochemical Data Base (AOGDB) in 1978 to house the data generated from USGS and subcontracted laboratories. Prior to the AOGDB, the accumulated data resided in a flat data...
Radar structure of earthquake-induced, coastal landslides in Anchorage, Alaska
Walter Barnhardt, Robert E. Kayen
2000, Environmental Geosciences (7) 38-45
Ground-penetrating radar (GPR) was used to investigate the internal structure of two large landslides in Anchorage, Alaska that resulted from the great 1964 earthquake. The Government Hill and Turnagain Heights landslides occurred in similar stratigraphic and geographic settings, yet the style of ground deformation is different at each site. GPR...

This dataset contains geochemical data for Alaska produced by the analytical laboratories of the Geologic Division of the U.S. Geological Survey (USGS). These data represent analyses of stream-sediment, heavy-mineral-concentrate (derived from stream sediment), soil, and organic material samples. Most of the data comes from mineral resource investigations conducted in the...
Stations in the USGS's National Stream Quality Accounting Network (NASQAN)

2000, Report
This is a point coverage of stations in the U.S. Geological Survey's National Stream Quality Accounting Network (NASQAN). NASQAN was established in 1973. Water-quality data currently is collected at NASQAN sites on bimonthly and quarterly intervals. However, some of the bimonthly stations will be sampled only five times a...

2000, Canadian Journal of Fisheries and Aquatic Sciences (57) 2319-2335
In May 1997, physical and biological variables were studied in 16 streams of different ages and contrasting stages of development following glacial recession in Glacier Bay National Park, southeast Alaska. The number of microcrustacean and macroinvertebrate taxa and juvenile fish abundance and diversity were significantly greater in older streams. Microcrustacean...

In the southern Beaufort Sea, polar bears are most common within the area of the outer continental shelf, where the hunt for seals along persistent...
Comparisons of methods for determining dominance rank in male and female prairie voles (Microtus ochrogastor)
Richard B. Lanctot, Louis B. Best
2000, Journal of Mammalogy (81) 734-745
Dominance ranks in male and female prairie voles (Microtus ochrogaster) were determined from 6 measurements that mimicked environmental situations that might be encountered by prairie voles in communal groups, including agonistic interactions resulting from competition for food and water and encounters in burrows. Male and female groups of 6 individuals...
