Preliminary assessment of landslide-induced wave hazards: Tidal Inlet, Glacier Bay National Park, Alaska
Gerald F. Wieczorek, Matthias Jakob, Roman J. Motyka, Sandra L. Zirnheld, Patricia Craw
2003, Open-File Report 2003-100
A large potential rock avalanche above the northern shore of Tidal Inlet, Glacier Bay National Park, Alaska, was investigated to determine hazards and risks of landslide-induced waves to cruise ships and other park visitors. Field and photographic examination revealed that the 5 to 10 million cubic meter landslide moved between...
Rocky Mountain snowpack chemistry at selected sites for 2001
George P. Ingersoll, M. Alisa Mast, David W. Clow, Leora Nanus, Donald H. Campbell, Heather Handran
2003, Open-File Report 2003-48
Because regional-scale atmospheric deposition data in the Rocky Mountains are sparse, a program was designed by the U.S. Geological Survey, in cooperation with the National Park Service, U.S. Department of Agriculture Forest Service, and other agencies, to more thoroughly determine the chemical composition of precipitation and to identify sources of...
Potentiometric Surface of the Magothy Aquifer in Southern Maryland, September 2002
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2003, Open-File Report 2003-256
This report presents a map showing the potentiometric surface of the Magothy aquifer in the Magothy Formation of Upper Cretaceous age in Southern Maryland during September 2002. The map is based on water-level measurements in 79 wells. The highest measured water level was 83 feet above sea level near the...
Potentiometric Surface of the Aquia Aquifer in Southern Maryland, September 2002
Stephen E. Curtin, David C. Andreasen, Judith C. Wheeler
2003, Open-File Report 2003-255
This report presents a map showing the potentiometric surface of the Aquia aquifer in the Aquia Formation of Paleocene age in Southern Maryland during September 2002. The map is based on water-level measurements in 94 wells. The highest measured water level was 38 feet above sea level near the northern...
User's Guide for the Agricultural Non-Point Source (AGNPS) Pollution Model Data Generator
Michael P. Finn, Douglas J. Scheidt, Gregory M. Jaromack
2003, Open-File Report 2003-130
BACKGROUND Throughout this user guide, we refer to datasets that we used in conjunction with developing of this software for supporting cartographic research and producing the datasets to conduct research. However, this software can be used with these datasets or with more 'generic' versions of data of the appropriate type. For...
Geophysical identification and geological Implications of the southern Alaska magnetic trough
R. W. Saltus, T. L. Hudson, Frederic H. Wilson
2003, Open-File Report 2003-200
The southern Alaska magnetic trough (SAMT) is one of the fundamental, crustal-scale, magnetic features of Alaska. It is readily recognized on 10 km upward-continued aeromagnetic maps of the state. The arcuate SAMT ranges from 30 to 100 km wide and extends in two separate segments along the southern Alaska margin...
African dust carries microbes across the ocean: are they affecting human and ecosystem health?
Christina A. Kellogg, Dale W. Griffin
2003, Open-File Report 2003-28
Atmospheric transport of dust from northwest Africa to the western Atlantic Ocean region may be responsible for a number of environmental hazards, including the demise of Caribbean corals; red tides; amphibian diseases; increased occurrence of asthma in humans; and oxygen depletion (eutrophication) in estuaries. Studies of satellite images suggest that...
Occurrence and distribution of dissolved trace elements in the surface waters of the Yakima River basin, Washington
Curt A. Hughes
2003, Water-Resources Investigations Report 2002-4177
The occurrence, distribution, and transport of dissolved (filtered-water) trace elements in the surface waters of the Yakima River Basin were assessed using data collected between 1999 and 2000 as part of the U.S. Geological Survey s National Water-Quality Assessment (NAWQA) Program. Samples were collected at 34 sites throughout the basin...
Comparison and continuous estimates of fecal coliform and Escherichia coli bacteria in selected Kansas streams, May 1999 through April 2002
Patrick P. Rasmussen, Andrew C. Ziegler
2003, Water-Resources Investigations Report 2003-4056
The sanitary quality of water and its use as a public-water supply and for recreational activities, such as swimming, wading, boating, and fishing, can be evaluated on the basis of fecal coliform and Escherichia coli (E. coli) bacteria densities. This report describes the overall sanitary quality of surface water in...
Total petroleum systems of the Paleozoic and Jurassic, Greater Ghawar Uplift and adjoining provinces of central Saudi Arabia and northern Arabian-Persian Gulf
Richard M. Pollastro
2003, Bulletin 2202-H
The greater Paleozoic and Jurassic petroleum systems of the Arabian Peninsula form two of the most prolific petroleum-producing systems in the world. Source rocks of these systems extend throughout the eastern Arabian Peninsula and Arabian-Persian Gulf. Primary elements of these Paleozoic and Jurassic petroleum systems - source, reservoir, and seal...
Geology of an Ordovician stratiform base-metal deposit in the Long Canyon Area, Blaine County, Idaho
B.R. Otto, G.A. Zieg
2003, Bulletin 2064-KK
In the Long Canyon area, Blaine County, Idaho, a strati-form base-metal-bearing gossan is exposed within a complexly folded and faulted sequence of Ordovician strata. The gossan horizon in graptolitic mudrock suggests preservation of bedded sulfides that were deposited by an Ordovician subaqueous hydrothermal system. Abrupt thickness changes and geochemi-cal zoning...
Revised Cretaceous and Tertiary stratigraphic nomenclature in the Colville Basin, Northern Alaska
Charles G. Mull, David W. Houseknecht, Kenneth J. Bird
2003, Professional Paper 1673
A revised stratigraphic nomenclature is proposed for Cretaceous and Tertiary geologic units of the central and western North Slope of Alaska. This revised nomenclature is a simplified and broadly applicable scheme suitable for a suite of digital geologic quadrangle maps being prepared jointly by the U.S. Geological Survey and the...
