Control of whirling disease (Myxosoma cerebralis): Use of methylene blue staining as a possible indicator of effect of heat on spores
G. L. Hoffman, M.E. Markiw
1977, Journal of Fish Biology (10) 181-183
Methylene blue staining (0.08 %) was used to determine efficiency of heat treatment in killing spores of Myxosoma cerebralis. Nearly all spores heated at 90°C for 10 min and 70°C for 100 min became stained giving presumptive evidence that they were killed....

This report presents selected basic data from a study of the ground- water resources of the Parowan Valley and Cedar City Valley drainage basins, Iron County, Utah. The study was made during 1973-75 by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water...
Classification of the hydrologic settings of lakes in the north central United States
Thomas C. Winter
1977, Water Resources Research (13) 753-767
The hydrologic settings of 150 lakes in the north central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic settings of lakes. Precipitation-evaporation balance and the water quality variables have high loadings on the first principal component. Highest loadings...
Remote sensing for lineaments in the Mississippi Embayment
D. O'Leary
1977, Earthquake Information Bulletin (USGS) (9) 14-18
A recurrence of an 1811-12 type earthquake in the Mississippi Valley would pose severe problems to construction in the valley. As William Stauder has stated in the preceding article, a particular difficulty in understanding the seismicity of this area is that, whereas various surface manifestations of the 1811-12 earthquakes have...
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD

Studying the Earth from space
Water Resources Division, U.S. Geological Survey
1977, Report
Pictures of the Earth's surface obtained from satellites are providing scientists with new tools to investigate the Earth and its environment. At the same time, a growing population and an ever-expanding technology place unprecedented demands on natural resources. Man can no longer treat his resources strictly according to immediate economic...
Binorm-a fortran subroutine to calculate the percentiles of a standardized binormal distribution
R.B. McCammon
1977, Computers & Geosciences (3) 335-339
BINORM is a FORTRAN subroutine for calculating the percentiles of a standardized binormal distribution. By using a linear transformation, the percentiles of a binormal distribution can be obtained. The percentiles of a binormal distribution are useful for plotting purposes, for establishing confidence intervals, and for sampling from a mixed population...
Demographic features of a lapland longspur population near Barrow, Alaska
Thomas W. Custer, Frank A. Pitelka
1977, The Auk (94) 505-525
Breeding density, clutch size, hatching and fledging success, and survival of adult Lapland Longspurs (Calcarius lapponicus) were monitored over a 7-year period near the Naval Arctic Research Laboratory, Barrow, Alaska. Nesting begins as soon as the tundra starts to clear of snow and appears to be timed so that the...

Mitigating earthquakes; the federal role
F. Press
1977, Earthquake Information Bulletin (USGS) (9) 4-5
With rapid approach of a capability to make reliable earthquake forecasts, it essential that the Federal Government play a strong, positive role in formulating and implementing plans to reduce earthquake hazards. Many steps are being taken in this direction, with the President looking to the Office of Science and Technology...

Revised age for Midway volcano, Hawaiian volcanic chain

1977, Earth and Planetary Science Letters (37) 107-116
New conventional K-Ar,40Ar/39Ar, and petrochemical data on alkalic basalt pebbles from the basalt conglomerate overlying tholeiitic flows in the Midway drill hole show that Midway evolved past the tholeiitic shield-building stage and erupted lavas of the alkalic suite27.0 ± 0.6m.y. ago. The data also show that previously published conventional K-Ar ages...
Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado
Leonard F. Konikow
1977, Water Supply Paper 2044
A solute-transport model that can be used to predict the movement of dissolved chemicals in flowing ground water was applied to a problem of ground-water contamination at the Rocky Mountain Arsenal, near Denver, Colo. The model couples a finite-difference solution to the ground-water flow equation with the method-of-characteristics solution to...

Earthquake history of Virginia
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 28-30
Virginia is a State of considerable seismic activity, although the earthquakes are rarely strong. Thirty-five shocks, intensity MM V or greater (Modified Mercalli Scale), are listed with epicenters within its borders. The locations of several of the older events are not precise; thus, the above count i subject to alteration....
Earthquakes in the United States
C. Stover
1977, Earthquake Information Bulletin (USGS) (9) 32-33
To supplement data in the report Preliminary Determination of Epicenters (PDE), the National earthquake Information Service (NEIS) also publishes a quarterly circular, Earthquakes in the United States. This provides information on the felt area of U.S earthquakes and their intensity. The main purpose is to describe the larger effects of these earthquakes so that...
