Importance of the Surf Zone of Exposed Sandy Beaches for the Development of Juvenile Trachinotus (Pisces, Carangidae)
Sandy beaches dominate most of the tropical and temperate coastlines. Studies of nearshore ichthyofauna, in different regions of the world, have revealed the frequent occurrence of juvenile...

Opportunities in Applied Oceanography in the California Current
Recent developments within the US oceanographic research community and around the world have made it possible to provide ocean and atmosphere information and products in near real time...

Multiple Use Ocean Management in the U.S.: Toward a New Conceptual Framework
Problems with the sectorally based, largely single-purpose approach to the management of ocean resources and ocean space in the United States have been amply documented in recent years....

A New Panama Canal?
Based upon the 1977 treaty between the United States and Panama and an exchange of diplomatic notes among Panama, Japan and United States, a trinational feasibility study is being conducted...

Observations of Seasonal and Interseasonal Variability in Shelikof Strait, Alaska
Nearly five years of monthly mean current data from two locations (one nearshore on the shallow shelf and one in the Shelikof sea valley) are used in conjunction with surface geostrophic...

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...

Rip Currents: Human Impact and Forecastibility
Annually, a large number of people in the United States drown in the surf zone. This study determines the number of surf drownings each year, mainly in Dade and Broward counties of southeast...

Infragravity Waves, Longshore Currents, and Linear Sand Bar Formation
A new hypothesis regarding the role of infragravity waves in controlling the formation and offshore migration of linear (2-dimensional) sand bars is presented. The hypothesis is dependent...

Sediment Transport by Strong Wave-Plus-Current Flows
A prediction formula is derived for the suspended sediment transport rate in coastal regions when the current speed and/or wave orbital velocity is large. It is based on generalised forms...

Shoreface Connected Ridges Along the Dutch Coast
Quasi-synoptic current measurements were obtained across the Dutch shoreface connected ridges using an acoustic Doppler current profiler. The measurements are used to evaluate the role...

Trapping and Escape of Fine-Grained Sediments: Neuse River Estuary, N.C.
The Neuse River estuary and its receiving basin, Pamlico Sound, are part of a system that comprises large, shallow bodies of water which have little or no free connection with the open...

On the Application of Multiphase Flow Models for the Simulation of Density Stratified Flow in Aquifers
Two types of numerical simulation approach are usually applied when simulating density-stratified flow in aquifers: (a) the sharp interface approach, and (b) the coupling of flow transport...

Gravitational Circulation in a Tidal Strait
Eight months of continuous measurements of tidal current profiles with an acoustic Doppler current profiler (ADCP) were made in Carquinez Strait, California, during 1988 for the purpose...

Coastal Zone '91
Coastal Zone '91 is the seventh in a series of biennial multidisciplinary symposia on comprehensive coastal and ocean management. The papers included in this proceedings review...

New Experimental Results on the Parameters Influencing Air-Sea Gas Exchange
Gas exchange experiments from large linear and circular facilities are presented which provide some more insight into the influence of waves on the gas exchange process. The experimental...

Stochastic Behavior of Concrete Arch Dam-Reservoir Fluid-Foundation Systems in Nonstationary Random Vibration
The behavior of elastic arch dam reservoir fluid system subjected to ground acceleration excitations has been studied extensively by Chopra and his colleagues. In their studies, the excitations...

Seismic Ground Motions for Lifeline Analysis
The spatial variation of seismic ground motions necessary for lifeline analysis is determined from a stochastic source model combined with a substitute system representing the equivalent...

Variability of Parameters of Earthquake Ground Motion Recorded by Strong Motion Arrays
The spatial variation of scalar measures of earthquake ground motion, such as peak ground acceleration, strong motion duration, and root-mean-square amplitude, along with various spectral...

Identification of a Site-Specific Ground Motion Model
The power spectral density and envelope function of earthquake ground accelerations at a site of interest are determined with the aid of system identification based on information predicted...

Critical Seismic Excitation for Structures
Critical seismic excitations are defined as stationary random functions with a given variance, which maximize the response variance of a linear structural dynamic system. A method is presented...
