Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns
Robert E. Gill Jr., L. Richard Mewaldt
1979, North American Bird Bander (4) 4-13
San Francisco Bay, California, including its fringing marshes, supports a large and diverse water related avifauna (Grinnell and Wythe 19271 Sibley 1952, Gill 1973, 1977). Certain of man's alterations of the Bay's shallower wetlands have resulted in increased habitat diversity which has allowed colonization by several species of birds including...
Tufted Puffins nesting in estuarine habitat
Robert E. Gill Jr., Gerald A. Sanger
1979, The Auk (96) 792-794
The Tufted Puffin (Lunda cirrhata) apparently has the most extensive breeding distribution of any North Pacific seabird, extending in the western North Pacific from Hokkaido to the north Chukotsk Peninsula on the Chukchi Sea, and in North America from Cape Lisburne on the Chukchi Sea, south to the Farallon Islands...

Paleozoic rocks on the Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1978
Robert L. Detterman, James E. Case, Frederic H. Wilson
1979, Circular 804-B
Two small areas of middle Paleozoic limestone were discovered near Gertrude Creek, 16 km north of Becharof Lake on the Alaska Peninsula, during reconnaissance flying as part of the Alaska Mineral Resource Assessment Program (AMRAP) for the Alaska Peninsula. Previously, the only known occurrence of Paleozoic rocks on the Alaska...
Histochemistry of leucine aminoaphthylamidase (LAN) in rainbow trout (Salmo gairdneri)
Gerald R. Bouck
1979, Transactions of the American Fisheries Society (108) 57-62
The histochemistry of leucine aminonaphthylamidase (LAN) was studied in frozen tissue sections of rainbow trout both in yearling and adult fish. Age of fish had relatively little effect upon the results. The most intense LAN color production was in epithelial cells of midgut, pyloric ceca, hindgut, and in some segments...
Geohydrology of Brooks, Lowndes, and western Echols Counties, Georgia
R.E. Krause
1979, Water-Resources Investigations Report 78-117
The principal artesian aquifer, a limestone of Eocene to Miocene age, is the main source of water supply for Brooks, Lowndes, and western Echols Counties in south Georgia. Pumpage of about 22 million gallons perday from this prolific aquifer has not posed any problems regarding declining water levels or depletion...
Hydrology and water quality in the Nederlo Creek Basin, Wisconsin, before construction of two water-retention structures
Phil A. Kammerer Jr., Marvin G. Sherrill
1979, Water-Resources Investigations Report 79-95
The Nederlo Creek basin, in the "Driftless Area" of southwest Wisconsin, is geographically and hydrologically similar to other small basins in the area. Topography is rugged, with approximately 400 feet of relief between the boundary ridge tops and the valley floor. The water-retention structures (a dry floodwater- retention structure and...
Low-flow characteristics of streams in the Trempealeau-Black River basin, Wisconsin
B. K. Holmstrom
1979, Water-Resources Investigations Report 79-9
Lov-flov characteristics of streams in the Trempealeau-Black River "basin are presented. Included are estimates of low-flow frequency and flow duration at 9 gaging stations, and low-flow frequency characteristics at 20 low-flow partial-record stations and 119 miscellaneous sites. Ten equations are provided to estimate low-flow characteristics at ungaged sites and at sites...

Records of prehistoric earthquakes in sedimentary deposits in lakes
J. Sims
Henry Spall, editor(s)
1979, Earthquake Information Bulletin (USGS) (11) 228-233
Historic records of earthquakes are too short to allow a true assessment of their recurrence intervals. Methods are needed, therefore, that will enable the seismicity of an area to be evaluated beyond the limit of historic records. One place where a record of ancient seismic activity might be preserved is in...
Laboratory experiments and preseismic slip

Modeling of rock friction 2. Simulation of preseismic slip
James H. Dieterich
1979, Conference Paper, Journal of Geophysical Research B: Solid Earth
The constitutive relations developed in the companion paper are used to model detailed observations of preseismic slip and the onset of unstable slip in biaxial laboratory experiments. The simulations employ a deterministic plane strain finite element model to represent the interactions both within the sliding blocks and between the blocks...
Modeling of rock friction 1. Experimental results and constitutive equations
James H. Dieterich
1979, Conference Paper, Journal of Geophysical Research B: Solid Earth
Direct shear experiments on ground surfaces of a granodiorite from Raymond, California, at normal stresses of ??6 MPa demonstrate that competing time, displacement, and velocity effects control rock friction. It is proposed that the strength of the population of points of contacts between sliding surfaces determines frictional strength and that...
A preliminary assessment of the timing and migration of shorebirds along the northcentral Alaska Peninsula

1979, Book chapter, Shorebirds in Marine Environments (Studies in Avian Biology no. 2)
An intensive study of post-breeding and migrating shorebirds was conducted in 1976 on a major estuary of the Alaska Peninsula at Nelson Lagoon. Twenty species were recorded, eight of them breeding on the study area. Temporal patterns of relative abundance were obtained from aerial and ground censuses. Prominent events in...
Worth of data and natural disaster insurance
E. D. Attanasi, M.R. Karlinger
1979, Water Resources Research (15) 1763-1766
The Federal Government in the past has provided medical and economic aid to victims of earthquakes and floods. However, regulating the use of hazard-prone areas would probably be more efficient. One way to implement such land use regulation is through the national flood and earthquake insurance program. Because insurance firms...

In this study the tectonic stress along active crustal fault zones is taken to be of the form , where is the average tectonic stress at depth y and Δσp(x, y) is a seismologically observable, essentially...
Maps for America: Cartographic products of the U.S. Geological Survey and others
Morris M. Thompson
1979, Report
This book was first conceived as being devoted entirely to descriptions of the maps produced by the U.S. Geological Survey. As the project developed, however, it became clear that the story of maps is not complete unless it is properly set in the background of the American mapping effort as a...

The need for disseminating current information on activities in the field of sedimentation was proposed by the Chairman of the Federal Interagency River Basin Committee's Subcommittee on Sedimentation shortly after the subcommittee was formed in May 1946. At the fifth meeting of the subcommittee on September 17, 1946, the members...
