Quaternary geologic map of the Lake Erie 4 degrees x 6 degrees quadrangle, United States and Canada
David S. Fullerton, Gerald M. Richmond, W.R. Cowan, W. D. Sevon, R. P. Goldthwait, W.R. Farrand, E.H. Muller, R.E. Behling, J.A. Stravers, Gerald Martin Richmond
David S. Fullerton, editor(s)
1991, IMAP 1420(NK-17)
The Quaternary Geologic Map of the Lake Erie 4? x 6? Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that...
Surface water quality assessment of the Upper Illinois River basin in Illinois, Indiana, and Wisconsin: Geochemical data for fine-fraction streambed sediment from high- and low-order streams, 1987
John A. Colman, R. F. Sanzolone
1991, Open-File Report 90-571
Geochemical data are presented from a synoptic survey of 46 elements in fine-fraction streambed sediments of the Upper Illinois River Basin during the fall of 1987. The survey was a component study of the Illinois pilot project of the U.S. Geological Survey's National Water-Quality Assessment program. Most of the sampling...
Floods in the Nishnabotna River basin, Iowa
D. A. Eash, A.J. Heinitz
1991, Open-File Report 91-171
Flood-elevation profiles and flood-peak discharges for floods during 1972, 1982, and 1987 in the Nishnabotna River basin are given in this report. The profiles are for the 1972 flood on the West and East Nishnabotna Rivers, the 1982 flood on Indian Creek, and the 1987 flood on the lower West...
Chufa biology and management
Leigh H. Fredrickson, James R. Kelley Jr.
1991, Fish and Wildlife Leaflet 13.4.18
Chufa (Cyperus esculentus) is an emergent perennial sedge that is common in seasonally flooded wetlands. Although chufa is common in many States, it is most abundant in the Southeast, including the Mississippi alluvial valley (Fig. 1). Belowground biomass of chufa, especially the tubers, serves as a valuable food source for...
Long-term decline in freshwater mussels (Bivalvia: Unionidae) of the western basin of Lake Erie
Thomas F. Nalepa, Bruce A. Manny, James C. Roth, Samuel C. Mozley, Donald W. Schloesser
1991, Journal of Great Lakes Research (17) 214-219
Long-term trends in the abundance of unionids in the western basin of Lake Erie were examined from data collected at 17 stations in 1961, 1972, and 1982. The mean number of unionids at these stations declined over this time period, decreasing from 10 m−2 in 1961, to 6 m−2 in...
Rehabilitation of a Species: The Black-Footed Ferret (Mustela nigripes)
Brian Miller, Dean E. Biggins, Lou Hanebury, Courtney Conway, Chris Wemmer
1991, Conference Paper, Proceedings of the Ninth Annual Wildlife Rehabilitation Association
Black-footed ferrets (Mustela nigripes) are an endangered carnivore endemic to North America.  This small nocturnal member of the weasel family is totally dependent on the prairie dog (Cynomys spp.) ecosystem for survival.  The ferret lives in prairie dog burrows and relies on prairie dogs for 90 percent of its diet...
Time-courses in the retention of food material in the bivalves Potamocorbula amurensis and Macoma balthica significance to the absorption of carbon and chromium
Alan W. Decho, Samuel N. Luoma
1991, Marine Ecology Progress Series (78) 303-314
Time courses for ingestion, retention and release via feces of microbial food was investigated using 2 bivalves with different feeding strategies, Potamocorbula amurensis and Macoma balthica. The results showed 2 pathways for the uptake of food material in these clams. The first is represented by an initial label pulse in the feces. The...
Crustal structure interpreted from magnetic anomalies
Jeffrey Phillips, Richard J. Reynolds, Herbert Frey
1991, Reviews of Geophysics (29) 416-427
In this review, we discuss publications during the last quadrennium (1987–1990) that used aeromagnetic data, marine magnetic data, satellite magnetic data, and rock magnetic and petrologic data to provide information on the sources of magnetic anomalies. Abstracts and papers by non‐U.S. authors are not described.The publications reviewed reflect increased integration...
Fractal hierarchies of magma transport in Hawaii and critical self- organization of tremor
H. R. Shaw, B. Chouet
1991, Journal of Geophysical Research (96) 10,191-10,207
A hierarchical model of magma transport in Hawaii is developed from the seismic records of deep (30-60 km) and intermediate-depth (5-15 km) harmonic tremor between January 1, 1962, and December 31, 1983. A tremor model of magma transport is developed from mass balances of percolation that are proportional to tremor...
