An Update to CoastWatch?NOAA's New Capability for the Coastal Ocean
The National Oceanic and Atmospheric Administration's (NOAA) CoastWatch project was initiated in August 1988 in response to a red tide event off the North Carolina coast....

A New Approach to Ocean Data Management
Ocean Data Management is the collection, storage, analysis and dissemination of a wide variety of physical, chemical, biological and geological data useful for research purposes in the...

Detection of 2-D Nearshore Wave Patterns Using Linear Prediction and SAR Data
Extraction of wave parameters such as wavelength and direction on radar images is normaly done using fast Fourier transforms (FFT) on typical image size of 256 ? 256 which may not be appropriate...

Pre-Operational Considerations for Marine Finfish Aquaculture: Site Selection and Allocation in British Columbia
Marine fish farming is a new component in the complex mixture of coastal resource uses in British Columbia. To ensure that the marine finfish aquaculture industry develops within an environmentally...

NOAA's Coastal Ocean Database and FOCOS Program
The NOAA Center for Ocean Analysis and Prediction (COAP) was recently formed in Monterey to support collection, distribution, and analysis of marine data for application to coastal ocean...

Numerical Simulation of Alabama's Weeks Bay Estuary
Weeks Bay system models describing water elevation, water circulation, salinity and BOD/DO concentrations are used to investigate two case study scenarios - a dredged ten foot deep boat...

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...

Moving Muds in the Marine Environment
Fine sediments with cohesive properties abound in the marine environment. We review idealized relationships that are useful in understanding flow behavior of important components of marine...

Alongshore Sediment Transport Rate Distribution
The initial analysis of a new set of experimental data on alongshore sediment transport rate distribution is presented. The distributions were generally found to be bimodal but tended...

G6 Coastal Morphodynamics
The contents and the backgrounds of the European coastal modelling programme 'G6 Coastal Morphodynamics', in the framework of the EC-sponsored Marine Science...

Turbulence Modelling of Suspended Sediment in the Surf Zone
A computational model is developed for the prediction of the wave period averaged turbulence structure under a breaking wave. The principal forcing function for the model is the generation...

Estimation of Overwash Bore Velocities Using Video Techniques
Overwash data were collected at a site on the Isles Dernieres, LA barrier island chain during Hurricane Gilbert in September 1988. A video technique was applied that allowed the quantification...

Phase Speed and Angle of Breaking Waves Measured with Video Techniques
The phase speed and incident angle of breaking surface gravity waves in the surf zone are measured using video processing techniques. The analysis of video data follows two lines. The...

Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....

Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...

Bedload Transport Measurement by Imaging of Tracers
A dyed-sand tracer technique is developed for investigation of bedload under laboratory oscillatory flows. Imaging of the tracer with high speed photography allows the creation of time...

Grain-Shape Analysis of Littoral and Shelf Sands, Southern California
Estimation of the exchange rates and determination of transport mechanisms and pathways associated with the onshore-offshore vector is one of the greatest sources of error in sediment...

Computer Simulation of Shore-Normal Variations in Sediment Size
A computer simulation model is presented which is designed to predict the selective shore-normal sorting of grain sizes in the nearshore environment. The model simulates wave shoaling,...
