Effect of capture stress on plasma enzyme activities in rainbow trout (Salmo gairdneri)
G.R. Bouck, M. A. Cairns, A. R. Christian
1978, Journal of the Fisheries Research Board of Canada 1485-1488
Four capture methods were used to collect domesticated rainbow trout (Salmo gairdneri): angling, electroshocking, seining, and direct netting (control). Blood was sampled rapidly upon capture, usually within 2 min. No significant differences were noted within the time frame of the experiment between the four capture groups for plasma protein concentration, lactate...
Volunteers in the earthquake hazard reduction program
P.L. Ward
1978, Earthquake Information Bulletin (USGS) (10) 139-143
One of the specific objectives of the Earthquake Hazard Reduction Act of 1977 is to educate the public, including State and local officials, about earthquakes. Although the Federal Government is significantly increasing its research efforts in earthquake studies, the ultimate benefits of this program will depend on whether the individual...

Sea-level changes before large earthquakes
M. Wyss
1978, Earthquake Information Bulletin (USGS) (10) 165-168
Changes in sea level have long been used as a measure of local uplift and subsidence associated with large earthquakes. For instance, in 1835, the British naturalist Charles Darwin observed that sea level dropped by 2.7 meters during the large earthquake in Concepcion, CHile. From this piece of evidence and...

Geomagnetic polarity event recorded at 1.1 m.y. B.P. on Cobb Mountain, Clear Lake volcanic field, California
Edward A. Mankinen, J.M. Donnelly, C. S. Grommé
1978, Geology (6) 653-656
Paleomagnetic studies show that a normal polarity event within the Matuyama reversed polarity epoch is recorded by one of the volcanic units on Cobb Mountain in northern California. K-Ar age determinations show that this event has an age of 1.12 ± 0.02 m.y. and clearly preceded the Jaramillo normal polarity...
Geomagnetic paleointensities from radiocarbon‐dated lava flows on Hawaii and the question of the Pacific nondipole low
Robert S. Coe, Sherman Gromme, Edward A. Mankinen
1978, Journal of Geophysical Research B: Solid Earth (83) 1740-1756
Radiocarbon ages have been published for nine basaltic lava flows on the island of Hawaii; the ages range from 2600 to somewhat older than 17,900 years B.P. By using the Thelliers' method in vacuum, geomagnetic paleointensity values were obtained from eight of the lavas; the ninth proved unsuitable. The paleointensities...
Paleomagnetic evidence for a Late Cretaceous deformation of the Great Valley Sequence, Sacramento Valley, California
Edward A. Mankinen
1978, Journal of Research of the U.S. Geological Survey (6) 383-390
Paleomagnetic samples from five localities within the Great Valley sequence range in age from Late Jurassic to Late Cretaceous. All samples possess normal polarity, and alternating-field demagnetization experiments show that the remanence was acquired after the sequence was folded. A mean paleomagnetic pole position determined from 17 demagnetized samples is...

1978, Open-File Report 78-506
In an area of 7,200 acres (29 sq km) In the Hanging Woman Creek study area, the Anderson coal bed contains potentially surface minable resources of 378 million short tons (343 million metric tons) of subbituminous C coal that ranges in thickness from 26 to 33 feet (7.9-10.1 m) at...

Comparison of a few recording current meters in San Francisco Bay, CA
R. T. Cheng
1978, Conference Paper, Proceedings, Conference on Current Measurements
A team of research scientists in the U.S. Geological Survey uses San Francisco Bay, California, as an outdoor laboratory to study complicated interactions of physical, chemical, and biological processes which take place in an estuarine environment. A current meter comparison study was conceived because of the need to select a...
K-Ar age of the late Pleistocene eruption of Toba, north Sumatra
D. Ninkovich, N. J. Shackleton, A. A. Abdel-Monem, J. D. Obradovich, G. Izett
1978, Nature (276) 574-577
The late Pleistocene eruption of Toba is the largest magnitude explosive eruption documented from the Quaternary. K-Ar dating of the uppermost unit of the Toba Tuff gives an age of [~amp]sim; 75,000 yr. A chemically and petrographically equivalent ash layer in deep-sea cores helps calibrate the Stage 4-5 boundary of...

The impacts of off-road vehicles on vegetation and soil were investigated at seven representative sites in the San Francisco Bay area. Plant cover of grass and chaparral (with shrubs to 4 m tall) have been stripped by the two- and four-wheel vehicles in use. Impacts on loamy soils include increased...

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...
Effects of paved surfaces on recharge to the Floridan aquifer in east-central Florida: A conceptual model
C. H. Tibbals
1978, Water-Resources Investigations Report 78-76
The proportionate amount of surface area that can be paved in Floridan aquifer recharge areas in east-central Florida without reducing the net recharge to the Floridan aquifer is a function of many variables that include rainfall, depth to water table, depth to potentiometric surface of the Floridan, evaporation from paved...
