Populations of mink (Mustela vison) have declined in many areas of the world. Such declines have been linked to exposures to synthetic, halogenated hydrocarbons. In the Great Lakes region, mink are fewer in areas along the shore of the Great Lakes and their tributaries where mink have access...

Fishes of the Great Lakes contain hazardous chemicals such as synthetic halogenated hydrocarbons and metals. These fish can move from the lakes into the Great Lakes tributaries of Michigan. In doing so, they transport concentrationsof contaminants which may represent a risk to wildlife. Concentrations of mercury (Hg), total polychlorinated biphenyls...
Rates and processes of bluff recession along the Lake Michigan shoreline in Illinois
R.W. Jibson, J. K. Odum, J.-M. Staude
1994, Journal of Great Lakes Research (20) 135-152
Examined bluffs along 30 km of the Lake Michigan shoreline from Wilmette to Waukegan, Illinois, to measure amounts and variation in retreat rates and to determine what factors control rates and processes of retreat. The predominant bluff-retreat process is shallow- to intermediate-depth translational landsliding triggered by heavy rainfall and wave...
A 4500-year record of large floods on the Colorado River in the Grand Canyon, Arizona
J. E. O’Connor
1994, Journal of Geology (102) 1-9
A sequence of flood deposits left by the Colorado River in the Grand Canyon, Arizona, provides evidence of at least 15 floods with peak discharges greater than over the last 4500 yr. Ten floods during the last 2000-2300 yr...
Paleoclimatic Inferences from a 120,000-Yr Calcite Record of Water-Table Fluctuation in Browns Room of Devils Hole, Nevada
Barney J. Szabo, Peter T. Kolesar, A.C. Riggs, I.J. Winograd, K.R. Ludwig
1994, Quaternary Research (41) 59-69
The petrographic and morphologic differences between calcite precipitated below, at, or above the present water table and uranium-series dating were used to reconstruct a chronology of water-table fluctuation for the past 120,000 yr in Browns Room, a subterranean air-filled chamber of Devils Hole fissure adjacent to the discharge area of...
Prediction of structural response to large earthquakes by using recordings from smaller earthquakes
Erdal Safak
1994, Conference Paper, Structures Congress XII
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can be approximated as linear combinations of records from smaller earthquakes. Two methods are introduced to predict structural response to a large earthquake by using the recorded...
Nonpoint and Point Sources of Nitrogen in Major Watersheds of the United States
Larry J. Puckett
1994, Water-Resources Investigations Report 94-4001
Estimates of nonpoint and point sources of nitrogen were made for 107 watersheds located in the U.S. Geological Survey's National Water-Quality Assessment Program study units throughout the conterminous United States. The proportions of nitrogen originating from fertilizer, manure, atmospheric deposition, sewage, and industrial sources were found to vary with climate,...

Emplacement and inflation of pahoehoe sheet flows: observations and measurements of active lava flows on Kilauea volcano, Hawaii
K. Hon, J. Kauahikaua, R. Denlinger, K. Mackay
1994, Geological Society of America Bulletin (106) 351-370
Inflated pahoehoe sheet flows have a distinctive horizontal upper surface, which can be several hundred meters across, and are bounded to steep monoclinal uplifts. The inflated sheet flows studied ranged from 1 to 5 m in thickness, but initially propagated as thin sheets of fluid pahoehoe lava, generally 20-30 cm...
Experimental studies of alunite: II. Rates of alunite-water alkali and isotope exchange
R.E. Stoffregen, R. O. Rye, M.D. Wasserman
1994, Geochimica et Cosmochimica Acta (58) 917-929
Rates of alkali exchange between alunite and water have been measured in hydrothermal experiments of 1 hour to 259 days duration at 150 to 400°C. Examination of run products by scanning electron microscope indicates that the reaction takes place by dissolution-reprecipitation. This exchange is modeled with an empirical rate equation...
Water resources activities in Kentucky, 1993-94
L. S. Maglothin (compiler), R.W. Forbes
1994, Open-File Report 93-157
The U.S. Geological Survey (USGS) is the principal Federal water-resources data collection and investigation agency. Through the Water Resources Division District Office in Kentucky, the USGS investigates the occurrence, distribution, quantity, movement, and chemical and biological quality of surface and ground water in the State. The mission of this program...
Mantle plume influence on the Neogene uplift and extension of the US western Cordillera?
T. Parsons, G. A. Thompson, Norman H. Sleep
1994, Geology (22) 83-86
espite its highly extended and thinned crust, much of the western Cordillera in the United States is elevated more than 1 km above sea level. Therefore, this region cannot be thought of as thick crust floating isostatically in a uniform mantle; rather, the...
Principal facts for gravity data in the Bethel and Russian Mission 1 degree x 3 degrees quadrangles, Alaska

Bethel and Russian Mission 1° x 3° quadrangles are located in southwestern Alaska near the mouth of the Kuskokwim River. The Russian Mission quadrangle now has about 266 gravity stations and the Bethel quadrangle has about 485 gravity stations.Riverboat traverses along the Yukon River in the northern part of the...

CASERTZ aeromagnetic data reveal late Cenozoic flood basalts (?) in the West Antarctic rift system
John C. Behrendt
1994, Geology (22) 527-530
The late Cenozoic volcanic and tectonic activity of the enigmatic West Antarctic rift system, the least understood of the great active continental rifts, has been suggested to be plume driven. In 1991-1992, as part of the CASERTZ (Corridor Aerogeophysics of the Southeast Ross...
Origin and evolution of the Seattle Fault and Seattle Basin, Washington
S. Y. Johnson, C. J. Potter, J.M. Armentrout
1994, Geology (22) 71-74
Analysis of seismic reflection data reveals that the Seattle basin (Washington) is markedly asymmetric and consists of ∼9-10 km of Eocene and younger deposits. The basin began as a discrete geologic element in the late Eocene (∼40 Ma), the result of a reorganization...

Lateral movement and stability of channel banks near four highway crossings in southwestern Mississippi
D. Phil Turnipseed
1994, Water-Resources Investigations Report 94-4035
Channel meandering in alluvial streams has caused localized channel instability that has resulted in bridge failure and loss of human life in Mississippi. The U.S. Geological Survey, in coopera- tion with the Mississippi Department of Transpor- tation, conducted a study to develop a better methodology for defining and estimating channel...
