Chung Jin S.Lunardini Virgil J.Chakrabarti S.K.Wang Y.S.Sodhi D.S.Karal K., editor(s)
1985, Conference Paper, Proceedings of the International Offshore Mechanics and Arctic Engineering Symposium
Besides providing an exact solution for steady-state heat conduction processes (Laplace Poisson equations), the CVBEM (complex variable boundary element method) can be used for the numerical error analysis of domain model solutions. For problems where soil water phase change latent heat effects dominate the thermal regime, heat transport can be...
STREAMFLOW LOSSES, CONSEQUENT FLOW THROUGH A THICK UNSATURATED ZONE, AND RECHARGE TO AN UNCONFINED AQUIFER.
J.R. Marie
1985, Conference Paper
Two experiments were conducted in conjunction with a 23-day aquifer test made in south-central Arizona to determine (1) water loss from a natural channel and (2) flow through a 330-foot-thick unsaturated zone overlying an unconfined aquifer. The experiments provided control for the aquifer test plus results relative to arid land...
GROUND-WATER DRAINAGE TO SURFACE MINES REFINED.
Linda S. Weiss
1985, Conference Paper
Changes in seepage flux and hydraulic head (ground-water level) resulting from ground-water drainage into the first and subsequent cuts of a surface coal mine can be estimated by a technique that considers drainage from the unsaturated zone and drainage effects of the advancing mine. A 'single-layer' technique is used, in...

C.P. Goodyear, J.E. Cohen, S.W. Christensen
1985, Transactions of the American Fisheries Society (114) 146-151
A mathematical technique was developed to examine interrelationships among first‐year survival rates, adult fecundity, and adult survival of striped bass Morone saxatilis based on indices of year‐class strength. Application of this technique to striped bass in Maryland waters of the Chesapeake Bay provided evidence for reduced survival in the life...
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...

R. Thorpe, G. Brown, H. Rymer, S. Barritt, M. Randal
1985, Earthquake Information Bulletin (USGS) (17) 44-49
The Costa Rican volacno Rincon de la Vieja is loosely but mysteriously translated as the "Old Lady's Corner." It consists of six volcanic centers that form a remote elongated ridge standing some 1300m above the surrounding terraine. Geologically speaking, the Guanacaste province of northern Costa Rica consists of a series...
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...
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...
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...
Deep continental margin reflectors
J. Ewing, J. Heirtzler, M. Purdy, Kim D. Klitgord
1985, Eos, Transactions, American Geophysical Union (66) 448-448
In contrast to the rarity of such observations a decade ago, seismic reflecting and refracting horizons are now being observed to Moho depths under continental shelves in a number of places. These observations provide knowledge of the entire crustal thickness from the shoreline to the oceanic crust on passive margins...
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...

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)....

Use of strontium isotopes to constrain the timing and mode of dolomitization of upper Cenozoic sediments in a core from San Salvador, Bahamas
Peter K. Swart, Joaquin Ruiz, Charles W. Holmes
1985, Geology (15) 262-265
The 87Sr/86Sr ratios and the activity ratios of 234U/238U and 230Th/238U have been measured in dolomites from a 168-m-deep core taken on the island of San Salvador, Bahamas. These data suggest two periods of dolomitization. The first episode dolomitized Miocene age sediments during the latest Miocene, and the second dolomitized the Pliocene portion...
Rapid postglacial shoreline changes in the western Gulf of Maine and the Paleo-Indian environment
Robert N. Oldale
1985, American Antiquity (50) 145-150
Rapid shoreline regression and transgression along the western Gulf of Maine between 13,000 and 9000 years B.P. are inferred to have produced a nearshore marine environment low in biologic productivity. Paleo-Indians living near the coast of the Gulf were probably forced to rely on nonmarine resources landward of the late-glacial...

Foraging recruitment by the Giant Tropical Ant Paraponera clavata (Hymenoptera, Formicidae)
Bruce A. Barrett, Clive D. Jorgenson, Sandra J. Looman
1985, Pan-Pacific Entomologist (61) 334-338
Increased foraging of an exceptionally abundant, but ephemeral, food source by ants can result from foraging excitement that does not include pheromone trails, tandem running, or from recruitment of other workers along pheromone trails (Carrol and Janzen, 1973). They also provided rationale for two types of short-lived pheromone trails resulting...
