1979, Geophysics (44) 1022-1033
Velocities were obtained from unreversed, refracted arrivals on analog records from a 48‐channel, 3.6-km hydrophone cable (3.89 km from the airgun array to the last hydrophone array). Approximately 200 records were analyzed along 1500 km of ship track on Georges Bank, northwest Atlantic Ocean, to obtain regional sediment velocity distribution...
Monitoring of subsurface injection of wastes, Florida
John Vecchioli
1979, Groundwater (17) 244-249
Injection of waste liquids into Florida's subsurface is physically feasible in many places but should be accompanied by monitoring of the waste-receiving aquifer system in addition to the injection facility. Monitoring of the interaction of factors including hydrogeologic conditions, well construction, waste volumes and characteristics, and potable-water sources is desirable...
Spectra of altered rocks in the visible and near infrared
G.R. Hunt, Roger P. Ashley
1979, Economic Geology (74) 1613-1629
Visible and near-infrared (0.35 to 2.5 mu m) bidirectional reflection spectra were recorded for a suite of well-characterized hydrothermally altered rock samples. The spectra typically display well-defined bands caused by both electronic and vibrational processes in the individual mineral constituents.Electronic transitions in the iron-bearing constituent minerals produce diagnostic minima near...
Habitat evaluation
1979, Water Spectrum (11) 26-34
Ours has been a nation of rapid growth and development; our abundant water and other natural resources were quickly utilized to meet the needs of our expansion. Resources perceived to be “important” to the national interest were often exploited at the expense of others. Fish and wildlife, because of their...
The composite dynamic method as evidence for age-specific waterfowl mortality
Kenneth P. Burnham, David R. Anderson
1979, Journal of Wildlife Management (43) 356-366
For the past 25 years estimation of mortality rates for waterfowl has been based almost entirely on the composite dynamic life table. We examined the specific assumptions for this method and derived a valid goodness of fit test. We performed this test on 45 data sets representing a...

During the 1976 water year, rainfall was 3.6 percent below average in Broward County, Fla. Water levels in the Pompano Beach and Dixie well fields were lower during the peak of the 1976 dry season than the peak of the record low dry season in 1971. Flow in the major...
Lakes of Oregon, Volume 6: Douglas County
Joseph F. Rinella
1979, Report
An inventory of lakes and reservoirs in Oregon is useful in evaluating the surface-water supply of the State and in providing answers to questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never been published. Those data were compiled...
The use of habitat structure preferenda for establishing flow regimes necessary for maintenance of fish habitat
Clair B. Stalnaker
1979, Book chapter, The Ecology of Regulated Streams
The pursuit of simplicity in the complex management of instream and out-of-stream water uses very early led to the minimum, or “base,” flow concept and the myth that a consistent methodology could be used to establish the desired minimum flow. Such a single flow value has not proven to be...

Geochemical and hydrologic considerations and the use of enthalpy-chloride diagrams in the prediction of underground conditions in hot-spring systems
R.O. Fournier
1979, Journal of Volcanology and Geothermal Research (5) 1-16
Thermal water ascending in a hot-spring system may cool by conduction of heat to the surrounding rock, by boiling, by mixing with cooler water, or by a combination of these processes. Complete or partial chemical reequilibration may occur as a result of this cooling. In spite of these complexities, in...

Jon E. Keeley
1979, Ecological Monographs (49) 89-108
Throughout the southeastern United States the hardwood Nyssa sylvatica (sensu lato) is distributed along a soil moisture gradient from upland sites, which are never flooded, to floodplains, which are periodically flooded and drained to permanently flooded swamps. Population differentiation with respect to flood tolerance and related physiological attributes was investigated...
Some basic considerations in the design of hydrologic data networks
Marshall E. Moss
1979, Water Resources Research (15) 1673-1676
Two preeminent considerations of data network design are the random nature of the hydrologic phenomena and the uses that will be made of the data. Information distilled from the data is usually measured in a parametric statistical sense, although the data user is more concerned with the integrated measure of...
Barometric fluctuations in wells tapping deep unconfined aquifers
Edwin P. Weeks
1979, Water Resources Research (15) 1167-1176
Water levels in wells screened only below the water table in unconfined aquifers fluctuate in response to atmospheric pressure changes. These fluctuations occur because the materials composing the unsaturated zone resist air movement and have capacity to store air with a change in pressure. Consequently, the translation of any pressure...
