1994, Book chapter, The geology of Alaska: Volume G-1 of Decade of North American Geology
The Aleutian arc is the arcuate arrangement of mountain ranges and flanking submerged margins that forms the northern rim of the Pacific Basin from the Kamchatka Peninsula (Russia) eastward more than 3,000 km to Cooke Inlet (Fig. 1). It consists of two very different segments that meet near Unimak Pass:...
Age-related reproduction in striped skunks (Mephitis mephitis) in the upper Midwest
Raymond J. Greenwood, Alan B. Sargeant
1994, Journal of Mammalogy (75) 657-662
Reproductive data from the upper Midwest are meager for the striped skunk (Mephitis mephitis), a common North American carnivore. We provide data on some age-related reproductive attributes of 178 female striped skunks collected at 19 sites in eastcentral North Dakota and westcentral Minnesota in 1979–1981 and 1987–1991. Seventy-four percent of...

Potentiometric surfaces of the intermediate aquifer system, west-central Florida, September, 1993
R. A. Mularoni
1994, Open-File Report 94-80
A map of the September 1993 potentiometric surface of the intermediate aquifer system in west- central Florida depicts water levels for the annual high water-level period. Water levels measured in September 1993 were generally below those reported for September 1992. In 134 wells with paired measurements, the September 1993 level...
Documentation of a computer program to simulate transient leakage from confining units using the modular finite-difference, ground-water flow model
S. A. Leake, P.P. Leahy, A. S. Navoy
1994, Open-File Report 94-59
Transient leakage into or out of a compressible fine-grained confining unit results from ground- water storage changes within the unit. The computer program described in this report provides a new method of simulating transient leakage using the U.S. Geological Survey modular finite- difference ground-water flow model (MODFLOW). The new...
Liquid-chromatographic determination of sarafloxacin residues in channel catfish muscle-tissue
J.R. Meinertz, V. K. Dawson, W.H. Gingerich, B. Cheng, M.M. Tubergen
1994, Journal of AOAC International (77) 871-875
A liquid chromatographic method is described for the determination of sarafloxacin hydrochloride residues in channel catfish (Ictalurus punctatus) fillets. Sarafloxacin was extracted from fillet tissue with acetonitrile–water (1+1). The extract was centrifuged and the supernatant was partitioned with hexane. The aqueous fraction was filtered through a 0.45 μm filter...
Declining survival of lake trout stocked during 1963-1986 in U.S. waters of Lake Superior

1994, North American Journal of Fisheries Management (14) 395-402
The average catch per effort (CPE) values for the 1963–1982 year-classes of stocked lake trout Salvelinus namaycush caught at age 7 in gill nets and for the 1976–1986 year-classes caught at ages 2–4 in trawls declined significantly in U.S. waters of Lake Superior. The declines in CPE were not explained by reduced...

The Geographic Information Retrieval and Analysis System (GIRAS) was developed in the mid 70s to put into digital form a numberof data layers which were of interest to the USGS. One of these data layers was the Hydrologic Units. The map is based on the Hydrologic Unit Maps published by...
Ground-water quality for Grainger County, Tennessee
J.D. Weaver, A.R. Patel, A.C. Hickey
1994, Open-File Report 93-365
The residents of Grainger County depend on ground water for many of their daily needs including personal consumption and crop irrigation. To address concerns associated with ground-water quality related to domestic use, the U.S. Geological Survey collected water samples from 35 wells throughout the county during the summer 1992....
