Sediment thicknesses and holocene glacial marine sedimentation rates in three east Greenland fjords (ca. 68°N)
J. T. Andrews, John D. Milliman, A. E. Jennings, N. Rynes, J. Dwyer
1994, The Journal of Geology (102) 669-683
We compared measured and estimated sediment budgets in heavily glaciated fjords in East Greenland. Mass balance calculations and regional glacio-climatic conditions suggest that the sediment flux to the seafloor in Kangerdlugssuaq and Nansen fjords should be dominated by iceberg rafting and not by the rain-out of suspended particulates in meltwater,...
Demographic and life history characteristics influence the cytonuclear composition of mosquitofish populations
Kim T. Scribner, John C. Avise
A. Beaumont, editor(s)
1994, Book chapter, Genetics and evolution of aquatic organisms
Experimental laboratory crosses and population experiments reveal significant differences in individual life-history traits and population demography between two related species of mosquitofish, Gambusia affinis and G. holbrooki. With respect to life-history traits, progeny from G. holbrooki exhibit larger size at birth and earlier age at sexual maturity than do progeny...

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...

Membrane-micelle model for humus in soils and sediments and its relation to humification
Robert L. Wershaw
1994, Water Supply Paper 2410
Humification, the process whereby biomass consisting of dead plant and animal remains is converted into soil organic matter (humus), is one of the basic processes of the carbon cycle. The organic compounds that make up plant and animal tissue are thermodynamically unstable in the oxidizing atmosphere at the surface of...
Overview of South‐east Asia land cover using a NOAA AVHRR one kilometer composite
Pierre Defourny, Udai C. Pradhan, Sritharan Vinay, Gary E. Johnson
1994, Geocarto International (9) 45-52
A cloud free AVHRR composite of South‐East Asia at one kilometer resolution has been produced from 38 selected daily NOAA‐11 AVHRR images. Geometric accuracy of about 1 pixel is achieved using a two‐step rectification algorithm (orbital model and transformation by ground control points). A spatial and spectral enhancement has been...

Prehistoric Alaska: The land

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...
United States Geological Survey, programs in Texas
Water Resources Division, U.S. Geological Survey
1994, Fact Sheet 043-95
Meteorologic and physiographic factors in parts of Texas combine to produce some of the most intense rainstorms in the Nation; these rainstorms cause severe, destructive floods somewhere in the State almost every year. A recent example is the catastrophic flooding in the Houston area in October 1994 that resulted in...

This report, Volume 1, includes records from the Delaware River Basin. Specifically, Volume 1...
Prospects for increasing the salt tolerance of forest trees: A review
J. A. Allen, J. L. Chambers, M. Stine
1994, Tree Physiology (14) 843-853
Three major themes related to the improvement of salt tolerance in forest tree species are examined. First, evidence demonstrating that substantial intraspecific variation in salt tolerance exists in many species is presented. This evidence is important because it suggests that efforts to improve salt tolerance through conventional plant breeding techniques are justified. Second, the...

In 1974–1975, 34 adult South Polar Skuas Catharacta maccormicki were colour-ringed on 18 nest territories at Bonaparte Point, Anvers Island, near Palmer Station along the Antarctic Peninsula. Subsequently, the area was searched for these birds during the austral summers of 1975–1976 to 1984–1985 and in 1987–1988 and 1989–1990. Fifty-three percent were seen...

Spatial and temporal statistical analysis of a ground-water level network, Broward County, Florida
E.D. Swain, R.S. Sonenshein
1994, Water-Resources Investigations Report 94-4076
The U.S. Geological Survey has developed a method to evaluate the spatial and temporal statistics of a continuous ground-water level recorder network in Broward County, Florida. Because the Broward County network is sparse for most spatial statistics, a technique has been developed to define polygons for each well that represent...

Hydrogeology and simulation of ground-water flow near the Lantana Landfill, Palm Beach County, Florida
G.M. Russell, E. J. Wexler

The Lantana landfill in Palm Beach County has a surface that is 40 to 50 feet above original ground level and consists of about 250 acres of compacted garbage and trash. Parts of the landfill are below the water table. Surface-resistivity measurements and water-quality analyses indicate that leachate-enriched ground water...
