Sanctuaries for lake trout in the Great Lakes
Jon G. Stanley, Randy L. Eshenroder, Wilbur L. Hartman
1987, Conference Paper, Coastal zone '87 : proceedings of the Fifth Symposium on Coastal and Ocean Management
Populations of lake trout, severely depleted in Lake Superior and virtually extirpated from the other Great Lakes because of sea lamprey predation and intense fishing, are now maintained by annual plantings of hatchery-reared fish in Lakes Michigan, Huron, and Ontario and parts of Lake Superior. The extensive coastal areas of...
Use of low-altitude aerial photography to identify submersed aquatic macrophytes
Donald W. Schloesser, Bruce A. Manny, Charles L. Brown, Eugene Jaworski
1987, Conference Paper, Color aerial photography in the plant sciences and related fields : proceedings of the Tenth Biennial Workshop on Color Aerial Photography in the Plant Sciences
The feasibility of using low-altitude aerial photography to identify beds of submersed macrophytes is demonstrated. True color aerial photos and collateral ground survey information for submersed aquatic macrophyte beds at 10 sites in the St.Clair-Detroit River system were obtained in September 1978. Using the photos and collateral ground survey information,...
Environmental pollutant and necropsy data for ospreys from the eastern United States, 1975-1982
Stanley N. Wiemeyer, Shelia K. Schmeling, Allen Anderson
1987, Journal of Wildlife Diseases (23) 279-291
Twenty-three ospreys (Pandion haliaetus) found dead or moribund in the eastern United States during 1975–1982 were necropsied and selected tissues were analyzed for organo-chlorines and metals. Major causes or factors contributing to death were trauma, impact injuries, and emaciation. DDE was detected in 96% of the osprey carcasses, DDD in...
Calculation of solar radiation in mountainous terrain
Alan L. Flint, S.W. Childs
1987, Agricultural and Forest Meteorology (40) 233-249
A study was performed to assess the accuracy of a daily solar radiation model for horizontal or sloping sites in terrain where surrounding ridges and tall trees block both direct beam and diffuse sky short wave radiation. To simulate adequately the major effects of these environments on radiation, the model...
Earthquakes, September-October 1986
W. J. Person
1987, Earthquakes & Volcanoes (USGS) (19) 74-76
There was one great earthquake (8.0 and above) during this reporting period in the South Pacific in the Kermadec Islands. There were no major earthquakes (7.0-7.9) but earthquake-related deaths were reported in Greece and in El Salvador. There were no destrcutive earthquakes in the United States....
Resource assessments, geologic deposit models, and offshore minerals with an example of heavy-mineral sands
Emil D. Attanasi, J. H. DeYoung, E. R. Force, Andrew Grosz
P. G. Teleki, M.R. Dobson, Jeffrey R. Moore, von Stackelberg U., editor(s)
1987, Book chapter, Marine minerals
A resource assessment method for offshore minerals based on descriptive and grade-tonnage models is proposed. Historical development and applications of this method are summarized. Based on this approach, descriptive and quantitative deposit models for strand-line titanium placer deposits have been developed. Descriptive statistics were also computed using the worldwide deposit...
New estimates of displacement along the San Andreas fault in central California based on paleobathymetry and paleogeography
Richard G. Stanley
1987, Geology (15) 171-174
Studies of depth-related benthic foraminiferal biofacies permit the construction of paleobathymetric maps of the La Honda and San Joaquin basins of central California. These maps support the hypothesis that the La Honda and San Joaquin basins were contiguous during the late Oligocene and early Miocene and subsequently were separated by...
Surficial aquifer system in eastern Lee County, Florida
D. H. Boggess, F. A. Watkins
1986, Water-Resources Investigations Report 85-4161
The surficial aquifer system in eastern Lee County consists of an upper water bearing unit, which is generally unconfined, and a lower water bearing unit, which is confined and is the major source tapped by most wells. The top of the lower unit, which is of primary interest in this...
Hydrogeologic conditions and saline-water intrusion, Cape Coral, Florida, 1978-81
D. J. Fitzpatrick
1986, Water-Resources Investigations Report 85-4231
The upper limestone unit of the intermediate aquifer system, locally called the upper Hawthorn aquifer, is the principal source of freshwater for Cape Coral, Florida. The aquifer has been contaminated with saline water by downward intrusion from the surficial aquifer system and by upward intrusion from the Floridan aquifer system....
Chemical effects of highway runoff on the surficial aquifer, Broward County, Florida
Barbara Howie, B.G. Waller
1986, Water-Resources Investigations Report 86-4200
In many areas of Broward County, swales are commonly designed to accept stormwater runoff from highways. Two sites adjacent to heavily traveled highways were studied to determine if stormwater percolating through unsaturated sand underlying the swales may affect the quality of water in the Biscayne aquifer. Concentrations of selected chemicals...
Later Paleozoic and Early Jurassic fossil ages from the McHugh Complex: A section in Geologic studies in Alaska by the U.S. Geological Survey during 1985 Circular 978
Steven W. Nelson, Charles D. Blome, Anita G. Harris, Katherine M. Reed, Frederic H. Wilson
1986, Circular 978
Late Mississippian through Early Pennsylvanian and Early Jurassic microfossils were collected from the type locality of the McHugh Complex (Clark, 1973) along the Seward Highway southeast of Anchorage (fig. 36). Radiolarians collected indicate that same of the oceanic rocks in the McHugh Complex are Early Jurassic in age. Conodonts extracted from...
Developing a state water plan: Ground-water conditions in Utah, spring of 1986
James L. Mason, G. J. Smith, D. Michael Roark, Patrick M. Lambert, V.L. Jensen, Dale E. Wilberg, Carole B. Burden, R. B. Garrett, D. C. Emett, Susan Duncanson, G. W. Sandberg, R. W Puchta, L. R. Herbert
1986, Cooperative Investigations Report 26
This is the twenty-third in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions.This report, like the...
