Nest spacing, habitat selection, and behavior of waterfowl on Miller Lake Island, North Dakota
John T. Lokemoen, Harold F. Duebbert, David E. Sharp
1984, Journal of Wildlife Management (48) 309-321
The nesting behavior of a concentration of nesting mallards (Anas platyrhynchos) and gadwalls (A. strepera) was studied on a 4.5-ha island in Miller Lake, North Dakota, in 1977. A single 0.59-ha clump of thick shrub contained 225 simultaneously active mallard nests on 10 May. During the peak nesting period, mallard...
Refuge management analyses: levee alternatives at Clarence Cannon National Wildlife Refuge
Gregor T. Auble, David B. Hamilton, James E. Roelle
1984, Report
This report documents the results of a workshop that examined levee alternatives at Clarence Cannon National Wildlife Refuge. This refuge is located along the Mississippi River, approximately 50 miles north of St. Louis. It was purchased primarily for waterfowl maintenance. A levee providing flood protection from the Mississippi River has...
Estimating the effect of hunting on annual survival rates of adult mallards
Kenneth P. Burnham, Gary C. White, David R. Anderson
1984, Journal of Wildlife Management (48) 350-361
Management programs for waterfowl populations include rationale for, and establishment of, hunting regulations. These programs rest partially on the results of scientific studies on the effect of harvest rates on annual survival rates. The evidence of this relationship has changed markedly since the mid-1970's, and it is not...

Dynamics of added nitrate and phosphate compared in a northern California woodland stream
Michael J. Sebetich, Vance C. Kennedy, S. Marc Zand, Ronald J. Avanzino, Gary W. Zellweger
1984, Journal of the American Water Resources Association (20) 93-101
Injections of NO3 and PO4 were made during September 1975 into Little Lost Man Creek, a small pristine stream in Redwood National Park, California. Chloride, a conservative constituent, was added in a known ratio to the nutrients. Nutrient loss at a downstream point was calculated using concentration of added Cl as a...
Ultrathin lava layers exposed near San Luis Obispo Bay, California
James G. Moore, D.W. Charlton
1984, Geology (12) 542-545
Sequences of extraordinarily thin (1–5 cm thick) lava layers, resembling individual lava flows, are interbedded with Jurassic and Cretaceous pillowed lava flows near San Luis Obispo Bay on the California coast. Such layers are formed inside submarine pillowed lava pipes or flow lobes. As the lava surface in a pillow...

R. W. Lee, Stephen H. Kirby
1984, Journal of Geophysical Research B: Solid Earth (89) 4161-4166
Crystallographically oriented single‐crystal prisms of gem quality topaz (composition AlSiO (OH− F) where x = 0.04 ± 0.01) were deformed at a confining pressure of 1.50 GPa, a temperature of 800°C, and a strain rate of 2×10 s. Under nearly identical conditions, all crystals of anhydrous rock‐forming minerals that have...
Geologic evolution, sedimentation, and paleoenvironments of the Angola Basin and adjacent Walvis Ridge: Synthesis of results of Deep Sea Drilling Project Leg 75
Walter E. Dean, W.W. Hay, Jean-Claude Sibuet
1984, Initial Reports of the D.S.D.P. (75) 509-544
The section recovered at Site 530 (Holes 53OA and 530B) consists of eight sedimentary units and one basalt unit. The composition of the basalt recovered in Hole 53OA is distinct from typical mid-ocean ridge basalts (MORBs) but is similar to that of Hawaiian tholeiites and basalt from the central part...
Origin and geochemistry of Cretaceous deep-sea black shales and multicolored claystones, with emphasis on Deep Sea Drilling Project Site 530, southern Angola Basin
Walter E. Dean, M.A. Arthur, D.A.V. Stow
1984, Initial Reports of the D.S.D.P. (75) 819-844
Deep-water sedimentary sequences of mid-Cretaceous age, rich in organic carbon, have been recovered at many DSDP sites in the Atlantic Ocean. Most of these sequences have a marked cyclicity in amount of organic carbon resulting in interbedded multicolored shale, marlstone, and (or) limestone that have cycle periods of 20,000 to...
Middle Cretaceous black shales at Site 530 in the southeastern Angola Basin
D.A. Stow, Walter E. Dean
1984, Initial Reports of the D.S.D.P. (75) 809-817
The middle Cretaceous black shale interval at Site 530 is 170 m thick and late Albian to Coniacian in age. The organic-carbon-rich sediments occur as 260 separate beds (average 4 cm, maximum 60 cm thick) and make up less than 10% of the recovered section. Associated lithologies are greenish, grayish,...
Shimada Seamount: An example of recent mid-plate volcanism
J. V. Gardner, Walter E. Dean, Richard J. Blakely
1984, GSA Bulletin (95) 855-862
Shimada Seamount is an isolated volcanic feature located between the Clipperton and Clarion Fracture Zones ∼1,150 km west of the East Pacific Rise and ∼600 km west of the inactive spreading center represented by the Mathematician Seamounts. It rises ∼3,900 m above the surrounding sea floor to within 50 m...
Models for the deposition of Mesozoic-Cenozoic fine-grained organic-carbon-rich sediment in the deep sea
M.A. Arthur, Walter E. Dean, D.A.V. Stow
1984, Geological Society of London Special Publications (15) 527-560
The widespread occurrence of organic-carbon-rich strata (‘black shales’) in certain portions of Jurassic, Cretaceous and Cenozoic sequences has been well-documented from Deep Sea Drilling Project sites in the Atlantic and Pacific Oceans and from sequences, now exposed on land, originally deposited in the Tethyan ocean. These ancient black shales...
Flow-through bioassay for measuring bioaccumulation of toxic substances from sediment
Michael J. Mac, Carol C. Edsall, Robert J. Hesselberg, Richard E. Sayers Jr.
1984, Report
Over 10 million cubic meters of sediment are dredged annually from Great Lakes waterways. Because much of this material is taken from harbors, connecting channels, and other nearshore areas that often are contaminated with toxic substances, the sediments proposed for dredging need to be evaluated for the presence of bioavailable...

Evaluation of potential embryotoxicity and teratogenicity of 42 herbicides, insecticides, and petroleum contaminants to mallard eggs
David J. Hoffman, Peter H. Albers
1984, Archives of Environmental Contamination and Toxicology (13) 15-27
Results are reported for the embryotoxicity of 42 environmental contaminants applied externally to mallard (Anas platyrhynchos) eggs including crude and refined petroleum, and commercial formulations of herbicides and insecticides. Many of the petroleum pollutants were embryotoxic and moderately teratogenic and had LD50s of 0.3 to 5 μl per egg (∼6–90 μg/g...
Remote sensing and geophysical investigations of glacial buried valleys in northeastern Kansas
Jane E. Denne, Harold L. Yarger, P. A. Macfarlane, Ralph W. Knapp, Marios A. Sophocleous, James R. Lucas, Don W. Steeples
1984, Groundwater (22) 56-65
Aquifers found in glacial buried valleys are a major source of good-quality ground water in northeastern Kansas. The extent and character of many of these deposits are not precisely known, so a detailed study of the buried valleys was undertaken. Test drilling, Landsat imagery, shallow-earth temperature...
The use of decoys to attract Least Terns (Sterna antillarum) to abandoned colony sites in New Jersey
Natasha B. Kotliar, Joanna Burger
1984, Colonial Waterbirds (7) 134-138
The number of Least Tern colony sites in New Jersey has declined in recent years. Decoys were used at two recently abandoned Least Tern colony sites in New Jersey to encourage nesting. The sites were chosen because of their apparent suitability as colony sites and the relative ease...
Maps & minds : mapping through the ages
Water Resources Division, U.S. Geological Survey

Surficial geology
Charles B. Hunt
1984, Report
Surficial materials are those at or near the Earth's surface. They constitute, by far, the largest and most used part of the ground around us. Areas not covered by surficial deposits--bare bedrock--form probably less than 5 percent of our land surface.Most surficial deposits are composed of poorly consolidated clay, silt,...

Refuge management analyses: research needs for Muscatatuck National Wildlife Refuge
J. E. Roelle, G.T. Auble, D. B. Hamilton
1984, Report
Muscatatuck National Wildlife Refuge, located in southeastern Indiana, was established by the Migratory Bird Conservation Commission in 1966. Land use planning for the Refuge formally began in 1971, and development of facilities designed in that planning effort is now nearing completion. As these facilities become operational, Refuge personnel will be...
