Biomechanics of Local Articular Incongruities
Abnormalities of intra-articular contact near sites of local surface incongruity are frequently associated with secondary osteoarthrosis. We here review a series of experimental and computational...

The Use of Computer Mapping to Establish Historical Erosion Rates and Coastal Cosntruction Setbacks in New Jersey
New Jersey's Rules on Coastal Zone Management define coastal policies which guide public decisions about significant proposed development and management of resources of New Jersey's coastal...

Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...

Sonar Mapping of Giant Kelp Density and Distribution
The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques...

Quantitative Mapping of Coastal Habitats and Natural Resource Distributions: Application to Narragansett Bay, Rhode Island
Effective management of the coastal zone is dependent on the availability of accurate information on the distributions of natural resources in both time and space. However, comprehensive...

Satellite Mapped Imagery for CoastWatch
The goal of CoastWatch, an activity within the new Coastal Ocean Program of the National Oceanic and Atmospheric Administration (NOAA), is to provide data and products for near real-time...

HF Radar Ocean Surface Mapping in Monterey Bay as a Prototype for California Coastal Environmental Monitoring and Governance
A network of coastal HF radars is being established to provide real-time coverage of ocean surface currents, onshore waves, and ultimately wind fields over Monterey Bay. Data products...

A Portable Geographic Information System (GIS) for Coastal Mapping
The combined increases in portable computing power and storage with the availability of new software has enabled the development of a truly portable Geographic Information System (GIS)...

Destruction Caused by Hurricane Hugo: A Timber Resources Damage Assessment in a Coastal Region
Damage assessments of large areas impacted by intense natural storms can be difficult. The purpose of this paper is to investigate the area and amount of damage to pine forests within...

Sediment Yield Location Maps
The West National Technical Center of the Soil Conservation Service is compiling a series of colored sediment yield location maps for the eleven western United States, as well as Alaska...

Accurate Shoreline Mapping: Past, Present, and Future
Mapping historical shoreline changes and predicting future shoreline positions requires both accurate and precise analyses of time-dependent fluctuations in water levels and sediment volumes...

Mapping Barrier Island Changes in Louisiana: Techniques, Accuracy, and Results
Changes in shoreline position along Louisiana's rapidly changing barrier coastline were compiled using cartographic data sources and aerial photography from 1855 to 1989. An interactive...

Accuracy Standards and Development of a National Shoreline Change Data Base
Data associated with mapping shoreline position provides baseline information used by scientists, managers, and planners for quantitative assessment of historical trends and prediction...

Keys to High-Accuracy Mapping of Shoreline Changes
For many years it has been difficult to overlay maps and aerial photographs with different scales and publication dates using conventional techniques. Large processing errors also made...
