2001, Marine Geology (175) 199-219
Advances in technology have resulted in a new instrument that is designed for in-situ determination of particle size spectra. Such an instrument that can measure undisturbed particle size distributions is much needed for sediment transport studies. The LISST-100 (Laser In-Situ Scattering and Transmissometry) uses the principle of laser diffraction to...

Basinsoft, a computer program to quantify drainage basin characteristics
Craig A. Harvey, David A. Eash
2001, Book chapter, GIS for Water Resource and Watershed Management
Surface water runoff is a function of many interrelated factors including climate, soils, landuse, and the physiography of the drainage basin. A practical and effective method to quantify drainage basin characteristics would allow analysis of the interrelations of these factors, leading to an improved understanding of the effects of drainage...
Benthic algae of benchmark streams in agricultural areas of eastern Wisconsin
Barbara C. Scudder, Jana S. Stewart
2001, Water-Resources Investigations Report 96-4038-E
Benthic algae were collected from 20 streams in the Western Lake Michigan Drainages by the U.S. Geological Survey in May and June of 1993 as part of the National Water-Quality Assessment program. These streams were selected to represent "benchmark" streams that were minimally affected by human activities, especially agriculture, for...

Effects of stream acidification and habitat on fish populations of a North American river
Barry P. Baldigo, Gregory B. Lawrence
2001, Aquatic Sciences (63) 196-222
Water quality, physical habitat, and fisheries at sixteen reaches in the Neversink River Basin were studied during 1991-95 to identify the effects of acidic precipitation on stream-water chemistry and on selected fish-species populations, and to test the hypothesis that the degree of stream acidification affected the spatial distribution of each...

Validation of a numerical modeling method for simulating rainfall-runoff relations for headwater basins in western King and Snohomish Counties, Washington
Richard S. Dinicola
2001, Water Supply Paper 2495
The validity of a previously determined numerical modeling method was assessed. Numerical models for 11 drainage basins were constructed with the Hydrologic Simulation Program-FORTRAN (HSPF) with parameter values that were generalized for the physiographic region. Large and recurrent simulation errors were initially identified, but three systematic modifications of the models...

2001, Book chapter, Past climate variability and change in the Arctic and at high latitudes: A report by the U.S. Climate Change Science Program and Subcommittee on Global Change Research.
Interpretation of paleoclimate records requires an understanding of Earth’s climate system, the causes (forcings) of climate changes, and the processes that amplify (positive feedback) or damp (negative feedback) these changes. Paleoclimatologists reconstruct the history of climate from proxies, which are those characteristics of sedimentary deposits that preserve paleoclimate information. A...
