Radium isotopes as tracers of coastal circulation pathways in the Mid-Atlantic Bight
… with half-lives of 4 days to 1600 years, a coastal source, and conservative properties in seawater, were used as coastal water mass tracers. The final study was comprised of data from 5 cruises, with a total of 8 cross-shelfbreak transects. Two areas were studied, a northern Mid-Atlantic …

The Effect of Submarine Canyon Width and Stratification on Coastal Circulation and Across Shelf Exchange
<p>A 3-D ocean circulation model is used to investigate the effect of the width of a submarine canyon and stratification on adjacent coastal circulation and across shelf exchange. Upwelling winds for 20 d drive circulation over six canyons of varying widths (8–60 km), two escarpments to represent …

Análise das variações morfodinâmicas por funções ortogonais empíricas - Praia do Flamengo (RJ)
… provide information for making decision in the coastal management, and to guide future works of coastal engineering. The profiles measured by survey were analyzed by EOF method (Empirical Orthogonal Functions). Also, there were performed grain size analysis, coastal circulation cells study, and …

Numerical Model Simulation of Offshore Flow During the Winter Season
… variability of heat and moisture flux in coastal zones, adequate descriptive models of mesoscale coastal circulation and weather patterns demand high spatial resolution in the analysis of wind, temperature and moisture patterns. To obtain realistic concepts of offshore flow the sparse …

Regional flow conditions associated with stratocumulus cloud-clearing events over the southeast Atlantic
… assess the character of the diurnal west-African coastal circulation. Our results indicate that the active period regularly experiences offshore flow from the continent above the boundary layer overnight, whereas the null period is associated with predominantly onshore flow along the coast …

The Role of Kelvin Waves on the Circulation and Salt Transport Variability in the Coastal Bay of Bengal
… until reaching Sumatra, where they follow the coastal waveguide counter-clockwise around the perimeter of the Bay of Bengal (BoB). We observed these Kelvin waves using the sea surface height (SSH) anomalies derived from satellite altimeter observations for the 1993-2006 period, the Simple Ocean …

The nearshore dynamics of Matroos Bay : field and theoretical investigations
… investigations were made of the nearshore circulation of Matroos Bay, a small embayment on the south-western coast of Africa. The field study revealed two dominant circulation types, denoted "anticlockwise" and "clockwise". The anticlockwise circulation type was characterized by longshore …

Can Waters Around Durney Key, Pasco County, Florida, Support Coral Recruitment to Artificial Substrates?
… the reef. Large-scale processes include coastal circulation, wave climate, and sediment dynamics that take place over spatial scales of tens to hundreds of kilometers in the region of the reef. Small-scale processes include the physical characteristics in the immediate vicinity of the …

High Resolution Circulation of the Hawkesbury Shelf Region, SE Australia: Mean, Variability and Transport Pathways
The exchange between the open ocean and coastal waters within continental shelf systems is driven by complex circulation processes making it hard to measure and observe. They are highly productive regions, sustaining marine ecosystems and are often nursery areas for many organisms, providing the …

Internal wave generation and its impact at the island Shelf
… provides an integrated analysis of island-shelf circulation and the generation of nonlinear internal waves (NIWs) in the Madeira Archipelago, a region characterized by steep bathymetry, a narrow insular shelf, and strong atmosphere–ocean interactions. Although Madeira has been widely studied in …

Inner Shelf Circulation in Coastal Virginia: A Data Assimilation Approach
… error of un-assimilated information. The mean circulation obtained over the inner shelf was less than 10 cm s<sup>−1</sup> and oriented along shelf. The mean flow and elevation reflected semigeostrophic dynamics with along shore pressure gradient balanced by friction and rotation, and cross …

Subtidal cross-shelf circulation on the Northern California shelf
Moored time series from the Coastal Ocean Dynamics Experiment (CODE), Shelf Mixed Layer Experiment (SMILE), Sediment Transport Events over the Shelf and Slope (STRESS) study, and Northern California Coastal Circulation Study (NCCCS) are used to study subtidal cross-shelf circulation over the …
