Effects of acidic deposition on water quality and forest health in Georgia Effects of acidic deposition on water quality and forest health in Georgia
Biogeochemical studies at the Panola Mountain Research Watershed near Atlanta, Ga., and in the Coastal Plain Province of Georgia have provided an assessment of some of the potential effects of acid deposition on streamwater quality and forest health in Georgia. Historically, "acid rain" has not been considered a potentially serious problem in the southeastern United States; however...

Preliminary results of the first scientific Drilling on Lake Baikal, Buguldeika site, southeastern Siberia Preliminary results of the first scientific Drilling on Lake Baikal, Buguldeika site, southeastern Siberia
The Baikal Drilling Project (BDP) is a multinational effort to investigate the paleoclimatic history and tectonic evolution of the Baikal sedimentary basin during the Late Neogene. In March 1993 the Baikal drilling system was successfuly deployed from a barge frozen into position over a topographic high, termed the Buguldeika saddle, in the southern basin of Lake Baikal. The BDP-93...

Offset-vertical seismic profiling for marine gas hydrate exploration: Is it a suitable technique? First results from ODP Leg 164 Offset-vertical seismic profiling for marine gas hydrate exploration: Is it a suitable technique? First results from ODP Leg 164
Walkaway vertical seismic profiles were acquired during Ocean Drilling Project (ODP) Leg 164 at the Blake Ridge to investigate seismic properties of hydrate-bearing sediments and the zone of free gas beneath them. An evaluation of compressional (P-) wave arrivals Site 994 indicates P-wave anisotrophy in the sediment column. We identified several shear (S-) wave arrivals in the horizontal

Morphology and stratal geometry of the Antarctic continental shelf: Insights from models Morphology and stratal geometry of the Antarctic continental shelf: Insights from models
Reconstruction of past ice-sheet fluctuations from the stratigraphy of glaciated continental shelves requires understanding of the relationships among the stratal geometry, glacial and marine sedimentary processes, and ice dynamics. We investigate the formation of the morphology and the broad stratal geometry of topsets on the Antarctic continental shelf with numerical models. Our models...

New approaches to the analysis of population trends in land birds: Comment New approaches to the analysis of population trends in land birds: Comment
James et al. (1996, Ecology 77:13-27) used data from the North American Breeding Bird Survey (BBS) to examine geographic variability in patterns of population change for 26 species of wood warblers. They emphasized the importance of evaluating nonlinear patterns of change in bird populations, proposed LOESS-based non-parametric and semi-parametric analyses of BBS data, and contrasted...

Surface-water quality changes after 5 years of nutrient management in the Little Conestoga Creek headwaters, Pennsylvania, 1989-91 Surface-water quality changes after 5 years of nutrient management in the Little Conestoga Creek headwaters, Pennsylvania, 1989-91
A 5.82-square-mile drainage basin in the headwaters of the Little Conestoga Creek in Lancaster County, Pa., was investigated from October 1989 through September 1991 as part of a longer-term effort to determine the effects of nutrient management on surface-water quality. A previous investigation found no statistical evidence that implementation of nutrient management from 1986 to 1989...

Scour at bridges, what's it all about? Stream stability and scour-assessment at bridges in Pennsylvania Scour at bridges, what's it all about? Stream stability and scour-assessment at bridges in Pennsylvania
Scour is the removal of sediment (soil and rocks) from streambeds and streambanks caused by movingwater. Although scour may occur at any time, it is usually more significant during high flows, when the water is swift and deep. Swiftly movingwater has more energy (turbulence and velocity) to lift and transport sediment than slowly moving water.
