1977, Conference Paper, Proceedings: Third International Coral Reef Symposium
Five core borings were taken on and around Boo Bee Patch Reef to better understand the origin of such shelf lagoon reefs. The cores reveal 4 stages of development: (1) subaerial exposure of a Pleistocene "high" having about 8 meters of relief, possibly a Pleistocene patch reef; (2) deposition of...

Earthquakes; January-February 1977
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 46-47
There were no major earthquakes (7.0-7.9) during the first 2 months of the year, and no fatalities were reported. Three strong earthquakes occurred- New Guinea, Tadzhik S.S.R, and the Aleutian Islands. The Tadzhik earthquake on January 31 caused considerable damage and possible injuries. The United States experienced a number of...
Earthquakes: August-September 1976
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 32-33
Destructive earthquakes continued to strike in many parts of the world during this period. The sparsely populated area of the New Hebrides Islands in the southwest Pacific was struck by a major earthquake (one with a magnitude between 7.0 and 7.9). A great earthquake (magnitude 8.0 or above) struck just...

Landslides
T. H. Nilsen
1977, Earthquake Information Bulletin (USGS) (9) 27-33
Landslides are frequent in areas where there is high seismicity and steep slopes. Landslides associated with earthquakes may cause as much damage as the initial ground shaking. They may also occur long after the earthquake. Some of the major earthquakes that have occurred during the past 15 years demonstrate the hazards...
Earthquakes; May-June 1977
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 26-27
The months of May and June were somewhat quiet seismically speaking. There was only on significant earthquake, a magnitude 7.2 on June 22 in teh Tonga Islands. In teh United States, the two largest earthquakes occurred in California and on Hawaii. ...

Measuring the size of an earthquake
W. Spence
1977, Earthquake Information Bulletin (USGS) (9) 21-23
Earthquakes occur in a broad range of sizes. A rock burst in an Idaho silver mine may involve the fracture of 1 meter of rock; the 1965 Rat island earthquake in the Aleutian arc involved a 650-kilometer lenght of Earth's crust. Earthquakes can be even smaller and even larger. if...

Earthquakes and plate tectonics
H. Spall
1977, Earthquake Information Bulletin (USGS) (9) 14-17
The world's earthquakes are not randomly distributed over the Earth's surface. They tend to be concentrated in narrow zones. Why is this? And why are volcanoes and mountain ranges also found in these zones too? An explanation is to be found in plate tectonics, a concept which has revolutionized thinking in...
Anisotropic magnetic susceptibility of erbium and ytterbium in zircon, ZrSiO4
A. N. Thorpe, Charles Briggs, T. Tsang, F. Senftle, Corrine Alexander
1977, Journal of Physics and Chemistry of Solids (38) 477-480
Magnetic susceptibility measurements have been made for both Er- and Yb-doped (1̃03ppm) zircon single crystals with the magnetic field perpendicular and parallel to the [001] axis. Large susceptibility anisotropies were found in both cases. Our observed anisotropies of ZrSiO4: Yb indicate small populations (1̃9%) of Yb ions at the axial...

This report contains climatologic and hydrologic data that were collected as a part of an investigation of the southeastern Uinta Basin, Utah and Colorado, by the U.S. Geological Survey. The data apply mainly to water years 1975 and 1976, which includes the period from October 1974 through September 1976. Included...
Rising ground-water level in downtown Louisville, Kentucky, 1972-1977

1977, Water-Resources Investigations Report 77-92
Ground-water levels in the alluvial aquifer in Louisville, Jefferson County, Kentucky, are rising at a rate which could cause wet basements and possible structural damage tc buildings in the downtown area by 1982. The predicted water level for 1982 is based on the nearly linear increase which has been observed...
Use of natural basin wetlands by breeding waterfowl in North Dakota

1977, Journal of Wildlife Management (41) 243-253
Use of basin wetlands by breeding populations of 12 species of waterfowl was investigated in 1965 and during 1967-69 throughout the prairie pothole region of North Dakota. Data were obtained primarily by random sampling techniques. Of the total population occupying natural basin wetlands 55 percent occupied seasonal and 36 percent...

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...

1977, Open-File Report 77-829
The Spokane Valley-Rathdrum Prairie aquifer is composed of unconsolidated Quaternary glaciofluvial deposits underlying an area of about 350 square miles. Transmissivities in the aquifer range from about 0.13 million to 11 million feet squared per day and ground-water velocities exceed 60 feet per day in some areas. The water-table gradient...
