Nucleation and growth of strike slip faults in granite
P. Segall, D.P. Pollard
1983, Journal of Geophysical Research Solid Earth (88) 555-568
Fractures within granodiorite of the central Sierra Nevada, California, were studied to elucidate the mechanics of faulting in crystalline rocks, with emphasis on the nucleation of new fault surfaces and their subsequent propagation and growth. Within the study area the fractures form a single, subparallel array which strikes N50°–70°E and...
Reassessment of the rates at which oil from natural sources enters the marine environment
K.A. Kvenvolden, J.W. Harbaugh
1983, Marine Environmental Research (10) 223-243
Previous estimates of the world-wide input of oil to the marine environment by natural seeps ranged from 0??2 to 6??0 million (metric) tonnes per year with a 'best estimate' of 0??6 million tonnes per year. Based on considerations of the availability of oil for seepage from the world's known and...
Distribution of mineral deposits in accreted terranes and cratonal rocks of western United States
J. P. Albers
1983, Canadian Journal of Earth Sciences (20) 1019-1029
The western margin of the conterminous United States, covering roughly 300 000 mi2 (777 000 km2), is an agglomeration of tectonostratigraphic terranes accreted to the North American craton mainly during Mesozoic time. The terranes represent a number of fundamental crustal types: oceanic crust, island-arc crust, mélange, various combinations of the preceding three, batholithic, miogeoclinal, and...
Ferruginous hawk populations and habitat use in North Dakota
David S. Gilmer, Robert E. Stewart
1983, Journal of Wildlife Management (47) 146-157
Ferruginous hawks (Buteo regalis) were studied in central North Dakota on a 1,259-km2 intensive study block and on a surrounding study area (16,519 km2) from 1977 to 1979. A total of 629 occupied nests was examined. Highest nest densities (0.08 nest/km2) were in the Missouri Coteau in 1979. Few nests...

Research note: Isolation of a herpesvirus from a bald eagle nestling
D. E. Docherty, R.I. Romaine, R.L. Knight
1983, Avian Diseases (27) 1162-1165
Cloacal swabs collected from wild bald eagle nestlings (Haliaeetus leucocephalus) were tested for viruses. A virus isolated from one of these samples had a lipid coat and contained DNA. Electron microscopy confirmed that it was a herpesvirus. This appears to be the first report of a herpesvirus isolation from a...
Stability of streams and lakes on Mars
M. H. Carr
1983, Icarus (56) 476-495
Under present climatic conditions streams and lakes on Mars will freeze. Freezing is slow and would have a negligible effect in impeding flow of the large floods that are believed to have eroded the outflow channels. Valley networks are more difficult...

A Symposium on the Giant Planets and Their Satellites was presented in conjunction with the Twenty-fourth Plenary Meeting of the Committee on Space Research. This paper summarizes the talks presented and places the remaining papers of this volume in context. ?? 1983....
Temporal patterns of seed use and availability in a guild of desert ants
Patricia Mehlhop, Norman J. Scott Jr.
1983, Ecological Entomology (8) 69-85
1Temporal patterns of seed use were studied from late winter to autumn in three species of seed-harvesting ants in the Sonoran Desert. Measures of effective foraging activity, dietary niche breadth and dietary niche overlaps were obtained each month and were tested for correlation with estimates of the...

The white pelican (Pelicanus erythrorhynchos) as a host of Pelecanectes apunctatus (Acarina: Hypoderidae)
B.N. Tuggle
1983, Journal of Parasitology (69) 1083-1083
Several species of nymphs from the family Hypoderidae have been reported from pelecaniform birds (Cerny, 1969, Folia Parasit. (Praha) 16:271-274; Pence, 1972, J. Med. Ent. 9: 435-438; Pence and Courtney, 1973, J. Parasitol. 59: 711-718); however, there are no records from the white pelican, Pelecanus erythrorhynchos. I report here the...
Maps for the nation: The current federal mapping establishment
Gary W. North
1983, Government Publications Review (10) 345-360
The U.S. Government annually produces an estimated 53,000 new maps and charts and distributes about 160 million copies. A large number of these maps are produced under the national mapping program, a decentralized Federal/State cooperative approach to mapping the country at standard scales. Circular A-16, issued by the Office of...

Comparison of analytical methods for the determination of silica in geothermal waters
J.C. Chemerys
1983, Journal of Volcanology and Geothermal Research (16) 57-63
The silica concentration of 26 Guatemalan geothermal waters were analyzed colorimetrically (spectrophotometrically) and by atomic absorption. Results by the atomic absorption method were less affected by polymerization and precipitation of silica from supersaturated solutions. Shaking the samples prior to analysis improves the accuracy of the atomic absorption results. The advantages...
Late Holocene ice wedges near Fairbanks, Alaska, USA: Environmental setting and history of growth
T. D. Hamilton, T. A. Ager, S.W. Robinson
1983, Arctic and Alpine Research (15) 157-168
Test trenches excavated into muskeg near Fairbanks in 1969 exposed a polygonal network of active ice wedges. The wedges occur in peat that has accumulated since about 3500 yr BP and have grown episodically as the permafrost table fluctuated in response to fires, other local site conditions and perhaps regional...

An isolated population of small Canada geese on Kaliktagik Island, Alaska
Scott A. Hatch, Martha A. Hatch
1983, Wildfowl (34) 130-136
Recently we discovered that a small form of the Canada Goose Branta canadensis breeds on Kaliktagik Island, one of the Semidi Islands, about 80 km south of the Alaska Peninsula near longitude 157°W (Figure 1). The unexpected occurrence of geese on this oceanic island and the possibility that they are...
Cenozoic structural history of selected areas in the eastern Great Basin, Nevada-Utah
R. Ernest Anderson
1983, Open-File Report 83-504
The Confusion Range structural trough (CRST) of west-central Utah predates the Oligocene rocks that are exposed along it. The northern part of the axial region of the CRST is complicated by structures that include reverse faults and associated folds, a large-amplitude mushroom fold, and belts of sharply flexed to overturned...
The role of remotely sensed and other special data for predictive modeling: the Umatilla, Oregon example
Thomas R. Loveland, Gary E. Johnson
1983, Photogrammetric Engineering and Remote Sensing (49) 1183-1192
Landsat data and 1:24 000-scale aerial photographs were initially used to map the expansion of irrigation from 1973 to 1979 and to identify crops under irrigation in 1979. The crop data were then used with historical water requirement figures and digital topographic and hydrographic data to estimate water and power...

The boundary between the States of Ohio and Kentucky and Indiana and Kentucky has been in dispute for many years. A major breakthrough in this continuing dispute has been a recent agreement between the States to accept the boundary line as depicted on U. S. Geological Survey 7. 5-minute quadrangle...
