Coupling of ocean bottom seismometers to sediment: Results of tests with the U.S. Geological Survey ocean bottom seismometer
Anne M. Trehu
1985, Bulletin of the Seismological Society of America (75) 271-289
The response of an ocean bottom seismometer (OBS) to a transient pull that excites the natural OBS-sediment coupling resonance can be modeled as a mass-spring-dashpot system in which the resonant frequency and damping are functions of instrument mass and bearing radius and of the physical properties of the sediment (primarily...
Occurrence and preservation of Eocene squamariacean and coralline rhodoliths: Eau, Tonga
Binyamin Buchbinder, Robert B. Halley
Donald F. Toomey, Matthew H. Nitecki, editor(s)
1985, Book chapter, Paleoalgology: Contemporary research and applications
A widespread rhodolith facies occurs within middle Eocene limestones of Eua, Tonga (Fig. 1). These limestones, first described by Hoffmeister (1932), represent a portion of a broad, early Tertiary platform that developed in the Tonga area prior to disruption and uplift by later Tertiary plate movements (Kroenke and Tongilava 1975)....
A note on the effect of bottom currents on an ocean bottom seismometer
Anne M. Trehu
1985, Bulletin of the Seismological Society of America (75) 1195-1204
Two three-component ocean bottom seismometers and a current meter were deployed a few hundred meters apart on the southern Blake Plateau off the United States eastern coast to study the effect of near-bottom currents on the background noise level of seismometers. Although analysis of the data is limited somewhat by...
Why deposits of longitudinal dunes are rarely recognized in the geologic record
David M. Rubin, Ralph E. Hunter
1985, Sedimentology (32) 147-157
Dunes that are morphologically of linear type, many of which are probably of longitudinal type in a morphodynamic sense, are common in modern deserts, but their deposits are rarely identified in aeolian sandstones. One reason for non-recognition of such dunes is that they can migrate laterally when they are not...
A drowned Holocene barrier spit off Cape Ann, Massachusetts
Robert N. Oldale
1985, Geology (13) 375-377
Seismic profiles and bathymetric contours reveal a drowned barrier spit on Jeffreys Ledge off Cape Ann, Massachusetts. Seaward-dipping internal reflectors indicate that a regressive barrier formed during the early Holocene low sea-level stillstand. Preservation of the barrier spit may have been favored by its large size (as much as 20...
New York Bight fault
Deborah R. Hutchinson, John A. Grow
1985, Geological Society of America Bulletin (96) 975-989
High-resolution, single-channel and multichannel seismic-reflection profiles in the New York Bight provide 7 crossings of a 50-km-long fault that trends north-northeast for 30 km from its southern end, then bends northeast, and may continue northward beneath Long Island. Displacement, which is consistently down to the west, decreases upsection and suggests...
Block Island fault: A Paleozoic crustal boundary on the Long Island platform
Deborah R. Hutchinson, Kim D. Klitgord, R. S. Detrick
1985, Geology (13) 875-879
A major fault cutting through most of the crust can be identified and mapped on the Long Island platform using multichannel seismic reflection profiles and magnetic data. The fault, here called the Block Island fault (BIF), strikes north-northeast, dips westward at low angle, and does not resemble the thin-skinned thrust...
Remote sensing; a geophysical perspective
K. Watson
1985, Geophysics (50) 2595-2610
In this review of developments in the field of remote sensing from a geophysical perspective, the subject is limited to the electromagnetic spectrum from 0.4 mu m to 25 cm. Three broad energy categories are covered: solar reflected, thermal infrared, and microwave.The reflected solar region has been the most intensely...
Evaluation of glutamic acid and glycine as sources of nonessential amino acids for lake trout (Salvelinus namaycush) and rainbow trout (Salmo gairdnerii)
S. G. Hughes
1985, Comparative Biochemistry and Physiology, Part A: Physiology (81A) 669-671
1. A semi-purified test diet which contained either glutamic acid or glycine as the major source of nonessential amino acids (NEAA) was fed to lake and rainbow trout.2. Trout fed the diet containing glutamic acid consistently showed better growth and feed conversion efficiencies than those fed the diets containing glycine.3....
Improving waterfowl production estimates: Results of a test in the prairie pothole region
P.M. Arnold, L.M. Cowardin
1985, International Congress of Game Biologists (17) 859-865
The U.S. Fish and Wildlife Service in an effort to improve and standardize methods for estimating waterfowl production tested a new technique in the four-county Arrowwood Wetland Management District (WMD) for three years (1982-1984). On 14 randomly selected 10.36 km2 plots, upland and wetland habitat was mapped, classified, and digitized....
EFFECT OF SANTA ROSA LAKE ON GROUND WATER FLOW TO THE PECOS RIVER, NEW MEXICO.
Dennis W. Risser
1985, Conference Paper
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa Rosa Lake has caused changes in the ground water flow system, which may cause changes in the streamflow...
Bald eagle mortality from lead poisoning and other causes 1963-1984
National Wildlife Health Laboratory.
1985, Report
In November 1984, the NWHL was assigned the task to:"Prepare a report of bald eagle mortality from lead poisoning and other causes. Determine whether primary causes of lead poisoning are due to ingestion of lead shot pellets. Prepare an appropriate map showing eagle concentrations and location of death. Make management...
GAS HYDRATES AT TWO SITES OF AN ACTIVE CONTINENTAL MARGIN.
K.A. Kvenvolden
1985, Conference Paper, Society of Petroleum Engineers of AIME, (Paper) SPE
Sediment containing gas hydrates from two distant Deep Sea Drilling Project sites (565 and 568), located about 670 km apart on the landward flank of the Middle America Trench, was studied to determine the geochemical conditions that characterize the occurrence of gas hydrates. Site 565 was located in the Pacific...
Contaminant trends in lake trout (Salvelinus namaycush) of the upper Great Lakes
David S. DeVault, Wayne A. Willford, Robert J. Hesselberg
1985, Report
Contaminant body burdens in lake trout from the Upper Great Lakes have been monitored since 1970 on Lake Michigan and since 1977 and 1978 on Lakes Superior and Huron by USEPA, Great Lakes National Program Office and USFWS, Great Lakes Fishery Laboratory. Analysis of the Lake Michigan data shows that mean...
