Trend analyses of sediment data for the DEC project Trend analyses of sediment data for the DEC project
Daily stream discharge, suspended-sediment concentration, and suspended-sediment discharge data were collected at eight sites in six watersheds of the Demonstration Erosion Control project in the Yazoo River Basin in north-central Mississippi during the period July 1985 through September 1991. The project is part of an ongoing interagency program of planning, design, construction...

Use of hydrologic budgets and hydrochemistry to determine ground-water and surface-water interactions for Rapid Creek, Western South Dakota Use of hydrologic budgets and hydrochemistry to determine ground-water and surface-water interactions for Rapid Creek, Western South Dakota
The study of ground-water and surface-water interactions often employs streamflow-gaging records and hydrologic budgets to determine ground-water seepage. Because ground-water seepage usually is computed as a residual in the hydrologic budget approach, all uncertainty of measurement and estimation of budget components is associated with the ground-water seepage. This uncertainty can...

Using GIS for verification of bathymetric data from Long Island sound Using GIS for verification of bathymetric data from Long Island sound
Accurate depiction of the topography of the seafloor in coastal areas is needed for modeling of ecosystems and processes, and also as a framework for analyzing and displaying information used in management decisions. Often, errors must be corrected before acquired digital data bases can be used. To create an acceptable data set, two corrected versions of a Long Island Sound data base...

Winter wolf predation in a multiple ungulate prey system, Gates of the Arctic National Park, Alaska Winter wolf predation in a multiple ungulate prey system, Gates of the Arctic National Park, Alaska
We investigated patterns of winter wolf predation, including prey selection, prey switching, kill rates, carcass utilization, and consumption rates for four wolf packs during three different study periods (March 1989, March 1990, and November 1990) in Gates of the Arctic National Park and Preserve, Alaska. Wolves killed predominantly caribou (165 caribou, seven moose, and five Dall sheep...

Wolf predation on caribou calves in Denali National Park, Alaska Wolf predation on caribou calves in Denali National Park, Alaska
During 1987-1991, 29 to 45 radio-collared caribou cows were monitored daily during calving each year and their calves were radio-collared (n = 147 calves) to investigate calf production and survival. We determined characteristics of wolf predation on caribou calves and, utilizing information from a companion wolf study, evaluated the role of spacing by caribou cows in minimizing wolf...

Strontium isotope geochemistry of soil and playa deposits near Yucca Mountain, Nevada Strontium isotope geochemistry of soil and playa deposits near Yucca Mountain, Nevada
The isotopic composition of strontium contained in the carbonate fractions of soils provides an excellent tracer which can be used to test models for their origin. This paper reports data on surface coatings and cements, eolian sediments, playas and alluvial fan soils which help to constrain a model for formation of the extensive calcretes and fault infillings in the Yucca Mountain...
