Velocity and bottom-stress measurements in the bottom boundary layer, outer Norton Sound, Alaska.
D.A. Cacchione, D.E. Drake, P. Wiberg
1982, Geologie en Mijnbouw (61) 71-78
We have used long-term measurements of near-bottom velocities at four heights above the sea floor in Norton Sound, Alaska, to compute hourly values of shear velocity u., roughness and bottom-drag coefficient. Maximum sediment resuspension and transport, predicted for periods when the computed value of u. exceeds a critical level, occur...
Nocturnal activity and foraging of prairie raccoons (Procyon lotor) in North Dakota
Raymond J. Greenwood
1982, American Midland Naturalist (107) 238-243
Nocturnal activity and foraging of 39 radio-equipped raccoons (Procyon lotor) in eastern North Dakota were studied from April-July in 1974-1976. Sixteen of the raccoons were collected after foraging bouts for stomach content analysis. Raccoon activity consisted of running (13%), walking (49%) and local movement in confined areas (38%). Local movement...
Multi-element analysis of manganese nodules by atomic absorption spectrometry without chemical separation
Jean S. Kane, J. M. Harnly
1982, Analytica Chimica Acta (139) 297-305
Five manganese nodules, including the USGS reference nodules A-1 and P-1, were analyzed for Co, Cu, Fe, K, Mg, Mn, Na, Ni and Zn without prior chemical separation by using a simultaneous multi-element atomic absorption spectrometer with an air—cetylene flame. The nodules were prepared in three digestion matrices. One of...
Holocene sedimentation in the shallow nearshore zone off Nauset Inlet, Cape Cod, Massachusetts
D.G. Aubrey, D.C. Twichell, S.L. Pfirman
1982, Marine Geology (47) 243-259
Present conditions and sedimentary evolution of the shallow offshore region near Nauset Inlet on Cape Cod, Massachusetts were clarified using high-resolution seismic-reflection profiles, sidescan-sonar records, surface grab samples and current meter measurements. The study area contains three provinces: (1) a nearshore province (shallower than 18 m) with a relatively steep...
Stream-grade variation and riparian-forest ecology along Passage Creek, Virginia
Cliff R. Hupp
1982, Bulletin of the Torrey Botanical Club (109) 488-499
Passage Creek, in northwestern Virginia, flows on relatively nonresistant shales, then cuts through a gorge underlain by resistant sandstone In the gorge, the stream gradient steepens, the size of bed material increases, a braided channel forms, and riparian-forest composition and growth form changes relative to areas outside the gorge Effects...
Bank stability and channel width adjustment, East Fork River, Wyoming
E.D. Andrews
1982, Water Resources Research (18) 1184-1192
Frequent surveys of eight cross sections located in self-formed reaches of the East Fork River, Wyoming, during the 1974 snowmelt flood showed a close relation between channel morphology and scour and fill. Those cross sections narrower than the mean reach width filled at discharges less than bankfull and scoured at...
Accumulation by fish of contaminants released from dredged sediments
James G. Seelye, Robert J. Hesselberg, Michael J. Mac
1982, Environmental Science & Technology (16) 459-464
Inasmuch as the process of dredging and disposing of dredged materials causes a resuspension of these materials and an increase in bioavailability of associated contaminants, we conducted a series of experiments to examine the potential accumulation by fish of contaminants from suspended sediments. In the first experiment we compared accumulation...

Paleomagnetic data from the Coso Range, California and current status of the Cobb Mountain normal geomagnetic polarity event
Edward A. Mankinen, C. Sherman Gromme
1982, Geophysical Research Letters (9) 1279-1282
Two basalt flows which erupted about 1.08 m.y. ago in the Coso Range, California, have normal magnetic polarity and thus provide additional evidence for the Cobb Mountain normal polarity event. A review of available data confirms that this event was of geomagnetic origin. A mean age of 1.10 ± 0.02...
Intraslope basins in Northwest Gulf of Mexico; a key to ancient submarine canyons and fans
A.H. Bouma
1982, Book chapter, M 34: Studies in Continental Margin Geology
The hummocky, diapirically deformed Texas-Louisiana continental slope includes three major types of intraslope basins: blocked-canyon intraslope basin, interdomal basin, and collapse basin. Major sand bodies present in the blocked-canyon intraslope basins are used to determine the sedimentary history of the Tertiary and Quaternary of this area. During relative lowering of...
Earthquakes of Loihi submarine volcano and the Hawaiian hot spot
F. W. Klein
1982, Journal of Geophysical Research Solid Earth (87) 7719-7726
Loihi is an active submarine volcano located 35 km south of the island of Hawaii and may eventually grow to be the next and southernmost island in the Hawaiian chain. The Hawaiian Volcano Observatory recorded two major earthquake swarms located there in 1971–1972 and 1975 which were probably associated with...
Distribution, mineralogy, and texture of manganese nodules and their relation to sedimentation at DOMES Site A in the equatorial North Pacific
David Z. Piper, J. R. Blueford
1982, Deep Sea Research Part A, Oceanographic Research Papers (29) 927-951
DOMES Site A, in the equatorial North Pacific, was surveyed in detail in an attempt to relate the distribution of nodules to sedimentation. The sea floor is characterized by a broad east-west-trending valley defined by strongly dissected highlands to the north and...
Variability in nest survival rates and implications to nesting studies
Albert T. Klett, Douglas H. Johnson
1982, The Auk (99) 77-87
We used four reasonably large samples (83-213) of Mallard (Anas platyrhynchos) and Blue-winged Teal (A. discors) nests on an interstate highway right-of-way in southcentral North Dakota to evaluate potential biases in hatch-rate estimates. Twelve consecutive, weekly searches for nests were conducted with a cable-chain drag in 1976 and 1977. Nests...
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...
Petrology and trace element geochemistry of the Honolulu volcanics, Oahu: Implications for the oceanic mantle below Hawaii
D.A. Clague, F.A. Frey
1982, Journal of Petrology (23) 447-504
The Honolulu Volcanics comprises small volume, late-stage (post-erosional) vents along rifts cutting the older massive Koolau tholeütic shield on Oahu, Hawaii. Most of these lavas and tuff of the Honolulu Volcanics have geochemical features expected of near-primary magmas derived from a peridotite source containing Fo87–89 olivine; e. g. 100 Mg/(Mg...

A computer model was calibrated to approximate predevelopment flow conditions in a multilayered aquifer system in 10,600 square miles in west-central Floria. The lowermost aquifer, called the Floridan aquifer, is confined in most of the study area and consists of carbonate rocks ranging up to 1,300 feet thick. The Floridan...
