Growth of submersed macrophyte communities in the St. Clair - Detroit River system between Lake Huron and Lake Erie
Donald W. Schloesser, Thomas A. Edsall, Bruce A. Manny
1985, Canadian Journal of Botany (63) 1061-1065
Growth of submersed aquatic macrophytes was determined from observation and on the basis of biomass of samples collected from April to November 1978 at seven study sites in a major river system of the Great Lakes, the St. Clair – Detroit river system between Lake Huron and Lake Erie. Growth...
Uptake, biotransformation, and elimination of rotenone by bluegills (Lepomis macrochirus )
W.H. Gingerich, J.J. Rach
1985, Aquatic Toxicology (6) 179-186
Yearling bluegills (Lepomis macrochirus) were exposed to sublethal concentrations of [14C]rotenone (5.2 μg/l) for 30 days in a continuous flow exposure system and then transferred to clean, flowing water for an additional 21-day depuration period. Rates of uptake and elimination and profile of the rotenoid metabolites in head, viscera, and...
Mapping and research in the exclusive economic zone
Bonnie A. McGregor, Millington Lockwood
1985, Report
By proclamation of the President on March 10, 1983, the United States claimed sovereign rights and jurisdiction within an Exclusive Economic Zone (EEZ). The United States is responsible for wisely developing and managing the EEZ and its marine resources and for protecting its environment. The U.S. Exclusive Economic Zone is...

Hydrogeology, digital solute-transport simulation, and geochemistry of the Lower Cretaceous aquifer system near Baltimore, Maryland
Francis H. Chapelle
1985, Maryland Geological Survey Report of Investigations 43
This study was made to develop information on the hydrogeology and ground-water geochemistry of the Patuxent and Patapsco aquifers (Lower Cretaceous) near Baltimore, Maryland. This information is needed to evaluate the availability and chemical quality of water from these aquifers.The Patuxent aquifer unconformably overlies Lower Paleozoic and Precambrian basement rocks...
Chronology of migration by American coots in Oklahoma
William R. Eddleman, Fritz L. Knopf, Craig T. Patterson
1985, Journal of Wildlife Management (49) 241-246
American coots (Fulica americana) were studied on large reservoirs in north-central Oklahoma in 1979-1982 to determine chronologies of migrations by age- and sex class. Coots began migrating into Oklahoma in mid-September, numbers peaked in early to mid-October, and few birds were seen after 1 November. Some late migrants...
Analysis of gravity data in volcanic terrain and gravity anomalies and subvolcanic intrusions in the Cascade Range, U.S.A., and at other selected volcanoes
David L. Williams, Carol A. Finn
William J. Hinze, editor(s)
1985, Book chapter, The utility of regional gravity and magnetic anomaly maps
Gravity data were investigated to reveal the presence of subvolcanic intrusions. With few exceptions, these intrusions produce a detectable gravity anomaly. In the past, these gravity anomalies have often been overlooked or misinterpreted because the data reduction procedure was inadequate. A pragmatic method for reducing and interpreting reconnaissance gravity data...
