Charles W. Holmes
1988, Developments in Sedimentology (42) 271-287
Three distinct carbonate deposits have been identified on the slope and adjacent sea floor of the southwestern Florida Platform: (1) reef talus, recognized by shape and location, found on the upper slope of the Yucatan Channel and also east of the Marquesas Keys; (2) hemipelagic sediments, with complex sigmoid-oblique...
Paleomagnetic results from the Shasta Bally Plutonic Belt in the Klamath Mountains Province, northern California
Edward A. Mankinen, William P. Irwin, C. Sherman Gromme
1988, Geophysical Research Letters (15) 56-59
Available paleomagnetic data show approximately 100° of clockwise rotation for Permian and Triassic strata of the Eastern Klamath terrane. Jurassic strata of this terrane are rotated approximately 60° clockwise, which is comparable to rotations reported for Jurassic plutons that occur elsewhere in the Klamath Mountains province. Paleomagnetic data obtained during...

R. A. Kerr
1988, Earthquakes & Volcanoes (USGS) (20) 114-119
The first official earthquake forecast for California emphasizes the broad extent of the hazard and the uncertainties involved in predicting the next quakes. For the first time, researchers have reached to a consensus on the threat of large earthquakes to California, things look no worse for Los Angles than before. It...
What is worse than the “big one”?
R. A. Kerr
1988, Earthquakes & Volcanoes (USGS) (20) 213-218
The Whittier Narrows California earthquake sequence (local magnitude, Ml=5.9 or 1 October, 1987), which caused over $358 million damage, indicates that assessments of earthquake hazards in Los Angeles metropolitan area may be underestimated. the sequence ruptured a previously unidentified thrust fault that may be part of a large system of...
Cathodoluminescent bimineralic ooids from the Pleistocene of the Florida continental shelf
R. P. Major, Robert B. Halley, Karen J. Lukas
1988, Sedimentology (35) 843-855
A bored and encrusted late Pleistocene ooid grainstone was recovered from the seafloor at a depth of approximately 40 m on the outer continental shelf of eastern Florida. Ooid cortices are dominantly bimineralic, generally consisting of inner layers of radial magnesian calcite and outer layers of tangential aragonite. Ooid nuclei...

Ground-water geochemistry of the Albuquerque-Belen Basin, central New Mexico
S. K. Anderholm
1988, Water-Resources Investigations Report 86-4094
The purpose of this study was to define the areal distribution of different water types, use the distribution to help define the groundwater flow system, and identify processes resulting in differences in groundwater quality in the Albuquerque-Belen Basin in central New Mexico. The chemistry of surface water inflow from adjacent...

A detailed chronology of the most recent eruption period at Mount Hood, Oregon
Kenneth A. Cameron, P. T. Pringle
1987, Geological Society of America Bulletin (99) 845-851
The most recent eruptive period of Mount Hood volcano, the Old Maid eruptive period, was characterized by volcano-hydrologic events (hydrologic events initiated by volcanic activity) which resulted in extensive lahar inundation in the White, Sandy, and Zigzag River drainages and produced a lithic pyroclastic flow which traveled at least 9...
Macrofauna and environment of the Nanpil-Kiepw River, Ponape, Eastern Caroline Islands
J. A. Maciolek, J.I. Ford
1987, Bulletin of Marine Science (41) 623-632
The first comprehensive evaluation of stream fauna in the Eastern Caroline Islands resulted from collections on Ponape, a 334-km- island having more than 40 streams, many of which arise along 700-m-high interior ridges. Field surveys centered on the Nanpil-Kiepw River below 170 m elevation, a bouldery reach with water of...
Water resources of Langlade County, Wisconsin
W.G. Batten
1987, Wisconsin Geological & Natural History Survey Information Circular 58
Langlade County depends almost exclusively on ground water pumped from the glacial sand and gravel deposits for its water needs. Well yields of 10 to 20 gallons per minute can be obtained from these deposits throughout most of the county. Yields of 500 to 1,000 gallons per minute are obtained...
Chemical and biological status of lakes and streams in the upper midwest: assessment of acidic deposition effects
J.G. Wiener, J.M. Eilers
1987, Lake and Reservoir Management (3) 365-378
Many lakes in three areas in the Upper Midwest - northeastern Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan - have low acid neutralizing capacity (ANC) and may be susceptible to change by acidic deposition. Northcentral Wisconsin and the Upper Peninsula of Michigan together contain about 150-300 acidic lakes...
Residues of organochlorine pesticides and polychloribiphenyls [sic] in starlings (Sturnus vulgaris), from the continental United States, 1982

1987, Environmental Monitoring and Assessment (8) 59-75
Starlings were collected from 129 sites throughout the contiguous United States in the fall of 1982 and analyzed for organochlorine compounds as part of a nationwide monitoring program. Residues of 14 organochlorine compounds were found. Only DDE, polychlorobiphenyls (PCB), dieldrin, and heptachlor epoxide occurred in more than 50% of the...
Black duck-mallard interactions on breeding areas in Maine
J. R. Longcore, P.O. Corr, D.G. McAuley
1987, Transactions of the Northeast Section, The Wildlife Society (44) 16-32
Mallard (Anas platyrhynchos) pairs (2-4) and broods (1-2) have occurred sporadically each year during recent (1977-86) waterfowl investigations in Maine. State-wide brood counts (1956-1986) for 36 wetlands in Maine depict an average increase of 1-3 mallard broods. Broods occurred mostly on man-made impoundments. Numbers of mallards captured during banding (as...
