Monitoring active volcanoes
R.I. Tilling
1980, Earthquake Information Bulletin (USGS) (12) 131-134
One of the most spectacular, awesomely beautiful, and at times, most destructive displays of natural energy is an erupting volcano, belching fume and ash thousands of feet into the atmoshpehere and pouring out red-hot molten lava in fountains and streams. ...

Charles F. Richter; an interview
H. Spall
1980, Earthquake Information Bulletin (USGS) (12) 4-8
Charles F. Richter, renowned seismologist, is a professor emeritus at the California Institue of techonology (Caltech). He is best known to the public for the Richter magnitude scale; but he is equally recognized in the scientific community for many other contributions to seismology including his books Elementary Seismology (1958) and...
An economical educational seismic system
J. D. Lehman
1980, Earthquake Information Bulletin (USGS) (12) 197-199
There is a considerable interest in seismology from the nonprofessional or amateur standpoint. The operation of a seismic system can be satisfying and educational, especially when you have built and operated the system yourself. A long-period indoor-type sensor and recording system that works extremely well has been developed in the...
Water quality of Tampa Bay, Florida, June 1972 - May 1976
Carole L. Goetz, Carl R. Goodwin
1980, Water-Resources Investigations Report 80-12
A comprehensive assessment of the water quality of Tampa Bay, Florida, was initiated in 1970 to provide background information to evaluate the effects of widening and deepening the ship channel to the port of Tampa. This report provides results of water-quality sampling in the bay from 1972 to 1976, prior...

Visitor use patterns in Yosemite National Park
J. W. van Wagtendonk
1980, Journal of Travel Research (19) 12-17
After several years of dramatic increases, visitor use in Yosemite National Park has leveled off to an average of 2.4 million visits per year. Coincident with this decline in the growth rate, there have been some changes in visitation trends and patterns. Data collected in the park show that the...

Goat paddock cryptoexplosion crater, Western Australia
J.E. Harms, D.J. Milton, J. Ferguson, D.J. Gilbert, W.K. Harris, B. Goleby
1980, Nature (286) 704-706
Goat Paddock, a crater slightly over 5 km in diameter (18??20??? S, 126??40???E), lies at the north edge of the King Leopold Range/Mueller Range junction in the Kimberley district, Western Australia (Fig. 1). It was noted as a geological anomaly in 1964 during regional mapping by the Bureau of Mineral...
A model to forecast short-term snowmelt runoff using synoptic observations of streamflow, temperature, and precipitation
Wendell V. Tangborn
1980, Water Resources Research (16) 778-786
Snowmelt runoff is forecast with a statistical model that utilizes daily values of stream discharge, gaged precipitation, and maximum and minimum observations of air temperature. Synoptic observations of these variables are made at existing low- and medium-altitude weather stations, thus eliminating the difficulties and expense of new, high-altitude installations. Four...
Secular, annual, and semiannual changes in the baseline level of the earth's magnetic field at North American locations
W.H. Campbell
1980, Journal of Geophysical Research Solid Earth (85) 6557-6571
Secular, annual, and semiannual changes were obtained from the midnight values of field on specially determined days of quiet magnetospheric conditions. From a selection of North American observatories the latitude variation of these changes was evaluated from 20° to 65°. Results for the active and quiet sun years (1958 and...
Tertiary δ18O record and glacio-eustatic sea-level fluctuations
R.K. Matthews, R.Z. Poore
1980, Geology (8) 501-504
Previous interpretation of the Tertiary δ18O record of plaiiktic and benthic foraminifers has emphasized comparison to the modern ocean, assumed an ice-free world prior to middle Miocene time, and thereby calculated surprisingly cool temperatures for the tropical sea surface. We propose an alternative...
On the extraction of directional sea-wave spectra from synthetic- aperture radar-signal arrays without matched filtering.
R.L. Wildey
1980, Modern Geology (7) 147-159
An economical method of digitally extracting sea-wave spectra from synthetic-aperture radar-signal records, which can be performed routinely in real or near-real time with the reception of telemetry from Seasat satellites, would be of value to a variety of scientific disciplines. This paper explores techniques for such data extraction and concludes...

Crude oil degradation as an explanation of the depth rule
L.C. Price
1980, Chemical Geology (28) 1-30
Previous studies of crude oil degradation by water washing and bacterial attack have documented the operation of these processes in many different petroleum basins of the world. Crude oil degradation substantially alters the chemical and physical makeup of a crude oil, changing a light paraffinic low-S "mature" crude to a...
Treasures from the deep ( Metallic nodules).
D.Z. Piper
1980, Water Spectrum (13) 8-15
The composition, distribution, metric growth rates and variations in sea-floor metallic nodules are outlined and discussed The considerable age, slow accretion and relationship to underlying sediments are problems of origin which are yet to be solved and some speculative answers are discussed. Mining of the nodules is reviewed and its...
Origin of gasoline-range hydrocarbons and their migration by solution in carbon dioxide in Norton basin, Alaska.
Keith A. Kvenvolden, George E. Claypool
1980, American Association of Petroleum Geologists Bulletin (64) 1078-1086
Carbon dioxide from a submarine seep in Norton Sound, Alaska, carries a minor component of gas- and gasoline-range hydrocarbons. The molecular and isotopic compositions of the hydrocarbon gases and the presence of gasoline-range hydrocarbons indicate that these molecules are derived from thermal alteration of marine and/or nonmarine organic matter buried...
