Analysis of the low-flow characteristics of streams in Louisiana
Fred N. Lee
1985, Water Resources Technical Report of the Louisiana Department of Transportation and Development, Office of Public Works 35
The U.S. Geological Survey, in cooperation with the Louisiana Department of Transportation and Development, Office of Public Works, used geologic maps, soils maps, precipitation data, and low-flow data to define four hydrographic regions in Louisiana having distinct low-flow characteristics. Equations were derived, using regression analyses, to estimate the 7Q2, 7Q10,...
YELLOWSTONE MAGMATIC-HYDROTHERMAL SYSTEM, U. S. A.
R.O. Fournier, A.D. Pitt
Stone Claudia, editor(s)
1985, Conference Paper
At Yellowstone National Park, the deep permeability and fluid circulation are probably controlled and maintained by repeated brittle fracture of rocks in response to local and regional stress. Focal depths of earthquakes beneath the Yellowstone caldera suggest that the transition from brittle fracture to quasi-plastic flow takes place at about...

1985, Conference Paper, Polar bears: Proceedings of the eighth working meeting of the IUCN/SSC Polar Bear Specialist Group
In 1979 the U.S. Fish and Wildlife Service continued its program of mark and recapture. From 31 March to 4 May field crews working at Point Barrow, Alaska, captured and marked a total of 15 polar bears (Table I). The small number was due to very poor ice conditions off...
RAPID REMOVAL OF A GROUNDWATER CONTAMINANT PLUME.
L. Jeff Lefkoff, Steven M. Gorelick
Schmidt Kenneth D., editor(s)
1985, Conference Paper
A groundwater management model is used to design an aquifer restoration system that removes a contaminant plume from a hypothetical aquifer in four years. The design model utilizes groundwater flow simulation and mathematical optimization. Optimal pumping and injection strategies achieve rapid restoration for a minimum total pumping cost. Rapid restoration...
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...
Comparison of digestion methods for total elemental analysis of peat and separation of its organic and inorganic components
C. S.E. Papp, T. F. Harms
1985, The Analyst (110) 237-242
In order to find the most efficient digestion method for the total elemental recovery in peat, ten samples were subjected to different techniques and analysed for Ca, Mg, Fe, AI, Na, K, Mn, P, Zn, Cu, Li, Cd, Co, Ni, Pb and Si using atomic-absorption spectrophotometry. The most satisfactory procedures...

Diversion of lava during the 1983 eruption of Mount Etna
J. P. Lockwood, R. Romano
1985, Earthquake Information Bulletin (USGS) (17) 124-133
Mankind's first known attempt to divert a lava flow was in 1669, when a flow from Mount Etna volcano threatened the Sicilian city of Catania. This attempt was largely unsuccessful, in part due to opposition by citizens of another town, Paterno. Attempts to divert lava flows from Mauna Loa Volcano...

Reducing losses from earthquakes through personal preparedness
W. J. Kockelman
1985, Earthquake Information Bulletin (USGS) (17) 50-59
Actions to reduce earthquake hazards can be divided into five phases:two occur before the event, one during the event, and two after the event. The phases are: (1) Mitigation techniques taken anywhere from 1 to 20 years before the event, (2) preparedness measures taken 1 to 20 weeks before the...

Kinds of damage that could result from a great earthquake in the central United States
M. G. Hooper, S. T. Algermissen
1985, Earthquake Information Bulletin (USGS) (17) 84-97
In the winter of 1811-12 a series of three great earthquakes occurred in the New Madrid, Missouri seismic zone in the central United States. In addition to the three principal shocks, at least 15 other earthquakes of intensity VIII or more occurred within a year of the first large earthquake...
Recent volcano monitoring in Costa Rica

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...
