Publication Extents

Not all publications have extents, not all extents are completely accurate
Publications of the U.S. Geological Survey, 1971-1981
Water Resources Division, U.S. Geological Survey
1986, Report
This catalog is a list of books and maps published between 1971 and 1981. It supplements the past permanent catalogs "Publications of the Geological Survey, 1879-1961" and "Publications of the Geological Survey, 1962-1970." It also lists those reports in the 1879-1961 and 1962-70 catalogs that are out of stock and...
Vegetation mapping of Nowitna National Wildlife Refuge, Alaska using Landsat MSS digital data
Stephen S. Talbot, Carl J. Markon
1986, Photogrammetric Engineering and Remote Sensing (52) 791-799
A Landsat-derived vegetation map was prepared for Nowitna National Wildlife Refuge. The refuge lies within the middle boreal subzone of north central Alaska. Seven major vegetation classes and sixteen subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, alluvial, subalpine); dwarf scrub (prostrate...
Long-term water-quality characteristics of Charlotte Harbor, Florida
T. H. Fraser
1986, Water-Resources Investigations Report 86-4180
Water-quality data for nine constituents collected from January 1976 through March 1984 in upper Charlotte Harbor were examined for evidence of trend (change) with time. Average seasonal patterns and moving averages were described to aid initial descriptions of variation. Multilinear regression models were developed using independent variables that are known...
New theories about ancient extinctions
H. Spall
1986, Earthquakes & Volcanoes (USGS) (18) 90-92
The abrupt disappearance of all the dinosaurs about 65 million years ago, along with perhaps half the plant species and other animals, has been one of the great geological mysteries. Clues to the cause of these extinctions have been scarce and open to many interpretations. But all this may be changing....
Earthquakes, January-February 1986
W. J. Person
1986, Earthquakes & Volcanoes (USGS) (18) 235-237
The first two months of the year were somewhat quiet seismically speaking. There were no major earthquakes (7.0-7.9) but one death was caused by an earthquake in Peru. In the United States a magntidue 4.9 earthquake in Ohio on January 31 caused some minor injuries and was felt in eleven states,...
The Pacific tsunami warning system
G. Pararas-Carayannis
1986, Earthquakes & Volcanoes (USGS) (18) 122-130
Of all natural disasters, tsunamis are among the most terrifying and complex phenomena, responsible for great loss of lives and vast destruction of property. Enormous destruction of coastal communities has taken place throughout the world by such great waves since the beginning of recorded history. The impact of tsunamis on human...
Guidelines to classification and nomenclature of Arabian felsic plutonic rocks
C.R. Ramsay, D. B. Stoeser, A.R. Drysdall
1986, Journal of African Earth Sciences (4) 13-20
Well-defined procedures for classifying the felsic plutonic rocks of the Arabian Shield on the basis of petrographic, chemical and lithostratigraphic criteria and mineral-resource potential have been adopted and developed in the Saudi Arabian Deputy Ministry for Mineral Resources over the...
Response of rainbow trout to source and level of supplemental dietary methionine
H. A. Poston
1986, Comparative Biochemistry and Physiology, Part A: Physiology (83) 739-744
1. Methionine and total sulfur amino acid (TSAA) requirements of rainbow trout (Salmo gairdneri) were investigated by feeding graded isosulfurous levels of l- and dl-methionine, l-cystine, and the free acid and calcium forms of methionine hydroxy analog (MHA).2. Added cystine did not promote growth, survival or prevent...
Jabal Silsilah tin prospect, Najd region, Kingdom of Saudi Arabia
du Bray
1986, Journal of African Earth Sciences (4)
A significant Sn deposit at Jabal Silsilah (26°07′N, 42°41′E), a prominent ring complex in the NE Arabian Shield, is associated with greisen in flat-topped cupolas of a highly evolved, zinnwaldite- and topaz-bearing alkali-feldspar granite. This granite is peraluminous, enriched in...
Magmatic inclusions in silicic and intermediate volcanic rocks
Charles R. Bacon
1986, Journal of Geophysical Research B: Solid Earth (91) 6091-6112
Fine‐grained ellipsoidal inclusions from a few millimeters to over l m in size are present in many intermediate to silicic lava flows and domes. Only recently has it become widely accepted that such inclusions are chilled blobs of magma. Their magmatic origin is manifested by vesicularity and high groundmass porosity,...
Water resources data for South Carolina, water year 1984
C.S. Bennett, R.D. Hayes, J.W. Gissendanner, K.H. Jones
1986, Water Data Report SC-84-1
Water resources data for the 1984 water year for South Carolina consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels of ground-water wells. This volume contains records for water discharge at 93 gaging stations, stage only...
Percentage entrainment of constituent loads in urban runoff, south Florida
R. A. Miller
1985, Water-Resources Investigations Report 84-4329
Runoff quantity and quality data from four urban basins in south Florida were analyzed to determine the entrainment of total nitrogen, total phosphorus, total carbon, chemical oxygen demand, suspended solids, and total lead within the stormwater runoff. Land use of the homogeneously developed basins are residential (single family), highway, commercial,...
Drought of 1980-82 in southeast Florida with comparison to the 1961-62 and 1970-71 droughts
B.G. Waller
1985, Water-Resources Investigations Report 85-4152
South-central Florida (the Kissimmee Basin) experienced a severe drought during 1980-82, causing Lake Okeechobee--the largest surface-water storage area in south Florida--to reach the lowest stage ever recorded, 9.75 feet above sea level, on July 29, 1981. A prolonged period of deficient rainfall extended from June 1980 to March 1982. On...
Geologic history of Goban Spur, Northwest Europe continental margin
P.C. de Graciansky, Claude (Wylie) Poag
1985, Initial reports of the Deep Sea Drilling Project (80) 1187-1216
Drilling on Leg 80 of the Deep Sea Drilling Project-International Phase of Ocean Drilling was conducted on a transect of four sites (548-551) across the continent-ocean boundary at Goban Spur, a prominent southwest-trending structural and topographic high on the Irish continental slope. Drilling results have been integrated with physiographic, gravimetric,...

J.M. Cleveland, T.F. Rees, K.L. Nash
1985, Nuclear Technology (69) 380-387
As part of a continuing study, plutonium, americium, and neptunium speciation was determined at 25 and 90°C in four groundwaters from diverse sources: the Sparta aquifer in Louisiana, near the Vacherie salt dome; Mansfield No. 2 well in the Palo Duro Basin, Texas; the Stripa mine in Sweden; and the...
Leaching of plutonium from a radioactive waste glass by eight groundwaters from the western United States
T.F. Rees, J.M. Cleveland, K.L. Nash
1985, Nuclear Technology (70) 133-140
The leachability of a radioactive waste glass formulated to Battelle Pacific Northwest Laboratory specification 80-270 has been studied using eight actual groundwaters with a range of chemical compositions as leachants. Waters collected from the Grande Ronde Basalt (Washington State) and from alluvial deposits in the Hualapai Valley (Arizona) were the...
