Empirical model of Skeletonema costatum photosynthetic rate, with applications in the San Francisco Bay estuary
James E. Cloern
1978, Advances in Water Resources (1) 267-274
An empirical model of Skeletonema costatum photosynthetic rate is developed and fit to measurements of photosynthesis selected from the literature. Because the model acknowledges existence of: 1) a light-temperature interaction (by allowing optimum irradiance to vary with temperature), 2) light inhibition, 3) temperature inhibition, and 4) a salinity effect, it accurately estimates...

Amplitude of foreshocks as a possible seismic precursor to earthquakes
A.G. Lindh
1978, Earthquake Information Bulletin (USGS) (10) 162-164
In recent years, we have made significant progress in being able to recognize the long-range pattern of events that precede large earthquakes. For example, in a recent issue of the Earthquake Information Bulletin, we saw how the pioneering work of S.A. Fedotov of the U.S.S.R in the Kamchatka-Kurile Islands region has...
Earthquakes; January-February, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 148-149
Seismically speaking, 1978 began slowly. The first major earthquake (magnitude 7.0 and above) of the year occurred on February 9 and was centered in the Kermadec Islands region in the South Pacific Ocean. The first destructive earthquake of the year strukc southern Honshu, Japan, on January 14. The magnitude 6.5...
Water-level monitoring in the area of the Palmdale Uplift, Southern California
D.L. Lamar, P.M. Merifield
1978, Earthquake Information Bulletin (USGS) (10) 144-147
Abnormal behavior of water levels in wells has been observed prior to a number of earthquakes. For instance, water-level minima have been noted in the Cienega Winery well before earthquakes on the San Andreas fault. Abnormal water-level fluctuations were used in conjunctions with other precursors to predict the February 4,...
Earthquakes; July-August 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 26-27
July and August were somewhat active seismically speaking, compared to previous months of this year. There were seven earthquakes having magnitudes of 6.5 or greater. The largest was a magnitudes of 6.5 or greater. The largest was a magnitude 8.0 earthquake south of Sumbawa Island on August 19 that killed...
Radon emanation on the San Andreas Fault
C. Y. King
1978, Earthquake Information Bulletin (USGS) (10) 136-138
Radon is a radioactive gas with a half-life of 3.8 days. (Half-life is the time required for the substance to lose half of its radioactivity by decay.) It is itself produced by the decay of uranium. Radon is constantly emanated from the Earth into the atmosphere. Many cases are known...
Earthquakes, March-April 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 192-194
Earthquakes caused fatalities in Mexico and Sicily; injuries and damage were sustained in eastern Kazakh SSR and Yugoslavia. There were four major earthquakes; one south of Honshu, Japan, two in the Kuril Islands region, and one in the Soviet Union. The United States experienced a number of earthquakes, but only...
Earthquakes, November-December 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 97-99
Two major earthquakes occurred in the last 2 months of the year. A magnitude 7.0 earthquake struck San Juan Province, Argentina, on November 23, causing fatalities and damage. The second major earthquake was a magnitude 7.0 in the Bonin Islands region, an unpopulated area. On December 19, Iran experienced a...

Earthquakes; November-December, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (11) 110-112
Seismically speaking, the last 2 months were the most active of the year. There were six major earthuakes having magnitudes (M) ranging from 7.0 to 7.9 throughout the world: the Solomon Islands, Mexico (the largest of the year, M=7.9), the Kuril Islands, Taiwan, the Philippine Islands, and western Iran. THe...

Wetland classification in the United States
L.M. Cowardin
1978, Journal of Forestry (76) 666-668
Wetland is part of a continuum of land types between deep water and dryland. Only one wetland classification was available for the United States prior to preparation of the new system described here, but numerous regional and special-purpose classifications are in use. The new classification is hierarchical, progressing from five...

Chemosterilization of the sea lamprey (Petromyzon marinus)
Lee H. Hanson, Patrick J. Manion
1978, Technical Report 29
The chemical, P,P-bis(1-aziridinyl)-N-methylphosphinothioic amide (bisazir), was found in laboratory studies to be an effective sterilant for both sexes of adult sea lampreys (Petromyzon marinus) when given intraperitoneally at a dosage of 100 mg per kilogram of body weight. A total of 300 normal spawning-run sea lampreys and 300 injected with...

Impact of potential phosphate mining on the hydrology of Osceola National Forest, Florida
James A. Miller, G.H. Hughes, R. W. Hull, John Vecchioli, P. R. Seaber
1978, Water-Resources Investigations Report 78-6
Potentially exploitable phosphate deposits underlie part of Osceola National Forest, Fla. Hydrologic conditions in the forest are comparable with those in nearby Hamilton County, where phosphate mining and processing have been ongoing since 1965. Given similarity of operations, hydroloigc effects of mining in the forest are predicted. Flow of stream...

Movements of walleyes tagged in eastern Lake Erie
David R. Wolfert, Harry D. Van Meter
1978, New York Fish and Game Journal (25) 16-22
In May, October and November of 1968, 2,456 walleyes of various ages were captured, tagged and released in eastern Lake Erie to determine seasonal movement of walleyes in that basin and the degree to which they intermingled with fish of the central and western basins. From 1968 to 1971, 275...
Age, growth, and food of northern pike in eastern Lake Ontario
David R. Wolfert, Terence J. Miller
1978, Transactions of the American Fisheries Society (107) 696-702
Northern pike (Esox lucius) from eastern Lake Ontario were sampled with gill nets and trap nets in 1972-1973. Fish of age-groups IV, V, and VI were predominant in the catch. Although males were slightly longer after the 1st yr of life, females gained a 25-mm advantage in the 2nd yr...
