Quaternary Geologic Map of the Platte River 4 Degrees x 6 Degrees Quadrangle, United States
Vincent H. Dreeszen, Gerald Martin Richmond, Merlin J. Tipton, Richard F. Bretz, Fred V. Steece, George R. Hallberg, Joseph E. Goebel
Gerald M. Richmond, editor(s)
1994, IMAP 1420(NK-14)
The Quaternary Geologic Map of the Platte River 4 degree x 6 degree Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed...
Herbicides and nitrate in near-surface aquifers in the midcontinental United States, 1991
Dana W. Kolpin, Michael R. Burkart, E. Michael Thurman
1994, Water Supply Paper 2413
The occurrence and distribution of selected herbicides, atrazine metabolites, and nitrate were determined for near-surface aquifers (within 50 feet of land surface) in the corn- and soybean-producing region of the midcontinental United States. The study region included all or parts of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North...
Activities of the Water Resources Division, California District, fiscal year 1993
M. L. DeBortoli (compiler)
1994, Open-File Report 94-67
This report summarizes the progress of water- resources studies in California by the U.S. Geological Survey during fiscal year 1993. Much of the work was done in cooperation with State and local agencies. Additional supporting funds were transferred from other Federal agencies or appropriated directly to the U.S. Geological Survey....
Prehistoric Alaska: The land
Frederic H. Wilson, Florence R. Weber
Penny Rennick, editor(s)
1994, Alaska Geographic (21) 6-23
Many Alaskans know the dynamic nature of Alaska’s landscape firsthand. The 1964 earthquake, the 1989 eruption of Mount Redoubt volcano, the frequent earthquakes in the Aleutians and the ever-shifting meanders of the Yukon and Kuskokwim rivers remind them of constant changes to the land. These changes are part of the...
A seabird monitoring program for the North Pacific
S.A. Hatcher, G.W. Kaiser, Alexander V. Kondratyev, G.V. Byrd
1994, Conference Paper, Transactions of the 59th North American wildlife and natural resources conference
Seabird monitoring is the accumulation of time series data on any aspect of seabird distribution, abundance, demography, or behavior. Typical studies include annual or less frequent measures of numbers or productivity; less commonly, the focus is on marine habitat use, phenology, food habits, or survival. The key requirement is that...
Coastal uplift associated with the 1992 Cape Mendocino earthquake, northern California
G. A. Carver, A. S. Jayko, D.W. Valentine, W.H. Li
1994, Geology (22) 195-198
The April 25,1992, Cape Mendocino earthquake (Ms 7.1) uplifted ∼24 km of the northern California coast at the southern end of the Cascadia subduction zone, uplift which resulted in coastal emergence that caused extensive mortality of intertidal organisms between Cape Men docino and Punta Gorda. We estimated the amount of...
Simulations of the origin of fluid pressure, fracture gen­ eration, and the movement of fluids in the Uinta Basin, Utah
J.D. Bredehoeft, J.B. Wesley, T. D. Fouch
1994, AAPG Bulletin (78) 1729-1747
The Altamont oil field in the deep Uinta basin is known to have reservoir fluid pressures that approach lithostatic. One explanation for this high pore-fluid pressure is the generation of oil from kerogen in the Green River oil shale at depth. A three-dimensional simulation of flow in the basin was...
[Book review] The Ancient Murrelet. A natural history in the Queen Charlotte Islands
Scott A. Hatch
1994, The Auk (111) 242-243
Leadership in ecological research on north-temperate-zone seabirds has long been associated with the region of the northeastern Atlantic, which enjoys a tradition of detailed, innovative work spanning several decades. Although the temperate North Pacific is home to several of the same species that figure prominently in the Atlantic and also...
Postbreeding dispersal and drift-net mortality of endangered Japanese Murrelets
John F. Piatt, Patrick J. Gould
1994, The Auk (111) 953-961
The incidental catch of seabirds in high-seas drift nets was recorded in 1990-1991 by scientific observers on commercial squid and large-mesh fishery vessels operating in the North Pacific Transitional Zone. Twenty-six Synthliboramphus murrelet deaths were recorded in the months of August through December. All but one were from the Korean...
Revised Ages for Laminated Sediment and a Holocene-Marker Diatom from the Northern California Continental Slope
E. Hemphill-Haley, J.V. Gardner
1994, Quaternary Research (41) 131-135
Conventional and accelerator mass spectrometry 14C ages indicate that laminated sediment in three cores from the northern California continental slope near 38??N and 39??N were deposited between 42,000 and 25,000 yr B.P. This revises and refines our previous estimates that laminated sediment accumulated during the late Pleistocene to early Holocene...
