James J. Rytuba, Richard K. Glanzman
1979, Papers on mineral deposits of western North America (Report 33) 109-117
The McDermitt caldera complex, located along the Nevada-Oregon border, is a Miocene collapse structure 45 km in diameter. Large-volume rhyolitic and peralkaline ash-flow tufts were erupted from 17.9-15.8 m.y. ago, leading to the formation of overlapping and nested calderas. Emplacement of rhyolitic ring domes, located primarily along the western margin...

1979, Technical Publication 66
Ground water in the Navajo Sandstone near Caineville, Wayne County, Utah, was studied during 1975-77 as part of an investigation of water in bedrock in the lower Dirty Devil River basin area. The purpose of the study near Caineville was to determine the water-bearing properties of the Navajo by utilizing...
Survival of one- and two-year-old monosex grass carp in small ponds
A.E. Thomas, Ray R. Carter, Donald C. Greenland
1979, Progressive Fish-Culturist (41) 38-38
Limited information has become available on the survival of monosex (female) grass carp (Ctenopharyngodon idella) reared in earthen ponds. Monosex fish produced in 1975 (Stanley 1976) were reared 27 months in earthen ponds at the Fish Farming Experimental Station, Stuttgart, Arkansas. Periodic transfers of these fish to different ponds afforded...
Synthetic fuels development: earth-science considerations

1979, Report
The current energy crisis is affecting the lives of all Americans. Continued increases in energy prices and frequent shortages are stark reminders of our growing dependence on foreign energy resources in today's energy-hungry world. A comprehensive national energy policy must consider a variety of energy resources, including synfuels, to meet...

This program begins to satisfy a longstanding need for a consistent level of detail, standardization in categorization, and scale of compilation...
Toxicity of fishery chemicals to the asiatic clam, Corbicula manilensis
Jack H. Chandler, L. L. Marking
1979, Progressive Fish-Culturist (41) 148-151
The Asiatic clam (Corbicula manilensis), a species introduced into U. S. waters, has spread rapidly, and its ability to survive, reproduce, and spread has caused concern. Aquatic biologists suspect that the clams may crowd out indigenous mollusks, and the animals sometimes plug water intakes and leave shell deposits that interfere...
Chloride inhibition of nitrite-induced methemoglobinemia in channel catfish (Ictalurus punctatus)
J.R. Tomasso, B.A. Simco, K. B. Davis
1979, Journal of the Fisheries Research Board of Canada (36) 1141-1144
Exposure of channel catfish (Ictalurus punctatus) fingerlings for 24?h to 1.0, 2.5, and 5.0?mg/L nitrite (pH?=?7; hardness?=?40?mg/L; temperature?=?22–25 °C) produced methemoglobin levels of 20.7?±?1.9%, 59.8?±?1.9%, and 77.4?±?1.4% (SE), respectively. However, methemoglobin levels were not elevated when fish were simultaneously exposed to 1.0, 2.5, and 5.0?mg/L nitrite and 25, 50, and...
United States Geological Survey Yearbook, fiscal year 1978
Water Resources Division, U.S. Geological Survey
1979, Report
Fiscal year 1978 saw the U.S. Geological Survey continuing to perform its basic historical missions of collecting, analyzing, and disseminating information about the Earth, its processes, and its water and mineral resources. Classifying Federal lands and supervising lessee mineral extraction operations on those lands were also major Survey concerns during...
Parathion causes secondary poisoning in a laughing gull breeding colony
Donald H. White, Kirk A. King, C. A. Mitchell, E. F. Hill, T. G. Lamont
1979, Bulletin of Environmental Contamination and Toxicology (23) 281-284
Use of organophosphate insecticides as replacements for the more persistent organochlorine compounds has increased dramatically in recent years. Organophosphates are desirable for field application because they break down rapidly in the environment and do not persist in animal tissues (Stickel 1974). Nevertheless, certain organophosphates are extremely toxic to wildlife for...

The concentrations of dissolved solids, chloride, and sulfate in Livingston Reservoir on the Trinity River in southeastern Texas usually average less than 250 mg/l (milligrams per liter), 40 mg/l, and 50 mg/l, respectively. The water is usually hard or moderately hard (61 to 180 mg/l as calcium carbonate). The concentrations...

Atlantic salmon embryos and fry: Effects of various incubation and rearing methods on hatchery survival and growth
Kenneth A. Leon, W.A. Bonney
1979, Progressive Fish-Culturist (41) 20-25
Significantly heavier fry of Atlantic salmon (Salmo salar) and greatly reduced mortality apparently resulted from the use of matrix substrates during egg incubation and alevin development. Salmon fry produced by this method fed readily and did not have the constricted yolk sacs that commonly occur when conventional rearing methods are used....
