Modified level II streambed-scour analysis for structure I-70-148-4528 crossing West Fork of East Fork Whitewater River in Wayne County, Indiana Modified level II streambed-scour analysis for structure I-70-148-4528 crossing West Fork of East Fork Whitewater River in Wayne County, Indiana
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sedient-transport data are evaluated to calculate the depth of scour that may result when given discharge is routed through a bridge opening. the results of the modified Levell II analysis for structure I-70-148-4528 on Interstate 70 crossing West Fork of East Fork Whitewater River in Wayne County, Indiana...

The wind-forced response on a buoyant coastal current: Observations of the western Gulf of Maine plume The wind-forced response on a buoyant coastal current: Observations of the western Gulf of Maine plume
The Freshwater plume in the western Gulf of Maine is being studied as part of an interdisciplinary investigation of the physical transport of a toxic alga. A field program was conducted in the springs of 1993 and 1994 to map the spatial and temporal patterns of salinity, currents and algal toxicity. The observations suggest that the plume's cross-shore structure varies markedly as a...

Quality-control design for surface-water sampling in the National Water-Quality Assessment Program Quality-control design for surface-water sampling in the National Water-Quality Assessment Program
The data-quality objectives of the National Water-Quality Assessment Program include estimating the extent to which contamination, matrix effects, and measurement variability affect interpretation of chemical analyses of surface-water samples. The quality-control samples used to make these estimates include field blanks, field matrix spikes, and replicates. This report describes the...

An example of endurance in an old wolf, Canis lupus An example of endurance in an old wolf, Canis lupus
An 11 to 13-year-old Arctic Wolf (Canis lupus arctos) was observed chasing a young Arctic Hare (Lepus arcticus) for 6 to 7 minutes and catching it. This provides an example of the degree of endurance of which an old wolf is capable.

The Chesapeake Bay bolide impact: A convulsive event in Atlantic Coastal Plain evolution The Chesapeake Bay bolide impact: A convulsive event in Atlantic Coastal Plain evolution
Until recently, Cenozoic evolution of the Atlantic Coastal Plain has been viewed as a subcyclical continuum of deposition and erosion. Marine transgressions alternated with regressions on a slowly subsiding passive continental margin, their orderly succession modified mainly by isostatic adjustments, occasional Appalachian tectonism, and paleoclimatic change. This passive scenario was...
