Seafloor environments in Cape Cod Bay, a large coastal embayment Seafloor environments in Cape Cod Bay, a large coastal embayment
Cape Cod Bay is a glacial, semi-enclosed embayment that has a patchy distribution of modern seafloor sedimentary environments of erosion or nondeposition, deposition, and sediment reworking. Sidescan-sonar records and supplemental bathymetric, sedimentary, subbottom, and physical-oceanographic data indicate that the characteristics and distribution of these three categories of bottom...

Proceedings of the ocean drilling program: New Jersey continental slope and rise Proceedings of the ocean drilling program: New Jersey continental slope and rise
The Scientific Results volumes of the Proceedings of the Ocean Drilling Program contain specialty papers presenting the results of extensive research in various aspects of scientific ocean drilling. The authors of the papers published in this volume have enabled future investigators to gain ready access to the results of their research, and I acknowledge their contributions with thanks...

Three-dimensional models of deformation near strike-slip faults Three-dimensional models of deformation near strike-slip faults
We use three-dimensional elastic models to help guide the kinematic interpretation of crustal deformation associated with strike-slip faults. Deformation of the brittle upper crust in the vicinity of strike-slip fault systems is modeled with the assumption that upper crustal deformation is driven by the relative plate motion in the upper mantle. The driving motion is represented by...

Oxygen transport and pyrite oxidation in unsaturated coal-mine spoil Oxygen transport and pyrite oxidation in unsaturated coal-mine spoil
An understanding of the mechanisms of oxygen (02) transport in unsaturated mine spoil is necessary to design and implement effective measures to exclude 02 from pyritic materials and to control the formation of acidic mine drainage. Partial pressure of oxygen (Po2) in pore gas, chemistry of pore water, and temperature were measured at different depths in unsaturated spoil at two...

Empirical Bayes estimation of proportions with application to cowbird parasitism rates Empirical Bayes estimation of proportions with application to cowbird parasitism rates
Bayesian models provide a structure for studying collections of parameters such are considered in the investigation of communities, ecosystems, and landscapes. This structure allows for improved estimation of individual parameters by considering them in the context of a group of related parameters. Individual estimates are differntially adjusted toward in overall mean, with the magnitude...

Merged GLORIA sidescan and hydrosweep pseudo-sidescan: Processing and creation of digital mosaics Merged GLORIA sidescan and hydrosweep pseudo-sidescan: Processing and creation of digital mosaics
We have replaced the usual band of poor-quality data in the near-nadir region of our GLORIA long-range sidescan-sonar imagery with a shaded-relief image constructed from swath bathymetry data (collected simultaneously with GLORIA) which completely cover the nadir area. We have developed a technique to enhance these "pseudo-sidescan" images in order to mimic the neighbouring GLORIA...

Effects of agricultural best-management practices on the Brush Run Creek headwaters, Adams County, Pennsylvania, prior to and during nutrient management Effects of agricultural best-management practices on the Brush Run Creek headwaters, Adams County, Pennsylvania, prior to and during nutrient management
The U.S. Geological Survey, in cooperation with the Susquehanna River Basin Commission and the Pennsylvania Department of Environmental Resources, investigated the effects of agricultural best-management practices on surface-water quality as part of the U.S. Environmental Protection Agency's Chesapeake Bay Program. This report characterizes a 0.63-square- mile agricultural watershed...

Evaluation of scour at selected bridge sites in Indiana Evaluation of scour at selected bridge sites in Indiana
Twenty bridge sites in Indiana were evaluated to determine: the extent of scour during floods, streambed stability, the maximum historical scour, and estimates of potential scour. Historical scour data were collected by means of geophysical methods and used to evaluate the scour-computation procedures recommended by the U.S. Federal Highway Administration and 13 other published pier...
