Slope/shelf circulation and cross-slope/shelf transport out of a bay driven by eddies from the open ocean
… Circumpolar Current and the continental slope/shelf in the Marguerite Bay and west Antarctic Peninsula is examined as interaction between a wind-driven channel flow and a zonally uniform slope with a bay-shaped shelf to the south. Two control mechanisms, eddy advection and propagation of …

Investigating the local circulation of the southeast Cape Basin
… observed at the mooring located on the shelf edge (1000m) and the moorings further offshore (2000m, 3000m and 45000m). The offshore circulation, observed by the moorings located on the 2000, 3000, 4500m isobaths, were driven by large mesoscale eddies, both cyclonic and anticyclonic, …

Freshwater Transport on the Continental Shelf of the Southeastern United States
<p>The circulation of water over the shelf of the southeastern United States was examined during the Fall Removal Experiment from late October to early November 1987. A steady state, two-dimensional analytical model of wind and density driven flow was used to study the relative importance of …

The role of short-term atmospheric variability in shaping Lagrangian transport in the Southern Benguela
… work studies the links between the Lagrangian transport in the Southern Benguela upwelling system and the ocean circulation through modelling experimentation. More specifically, it intends to show that the wind-induced circulation at short-time scales impacts the drift of Lagrangian particles …

Radium isotopes as tracers of coastal circulation pathways in the Mid-Atlantic Bight
Pathways of exchange between the shelf and slope in the Mid-Atlantic Bight were investigated using a combination of radiochemical tracer and hydrographic measurements. The motivation was to provide evidence of transport routes for shelfwater that could be important to the balance of shelf-slope …

Cross-shelf circulation and momentum and heat balances over the inner continental shelf near Martha's Vineyard, Massachusetts
… of water temperature over the inner continental shelf are investigated using observations of water velocity, temperature, density, and bottom pressure; surface gravity waves; wind stress; and heat flux between the ocean and atmosphere during 2001-2007. When waves are small, cross-shelf wind …

Wind-driven circulation on a shallow, stratified shelf
Data from the Coastal Ocean Processes Inner Shelf Study are analyzed to determine atmospheric forcing characteristics and the heat balance of the inner shelf, and are used as motivation for a numerical study of inner shelf circulation during upwelling and downwelling. Variation in meteorological …

High Resolution Circulation of the Hawkesbury Shelf Region, SE Australia: Mean, Variability and Transport Pathways
… 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 basis for a variety of …

Temporal variability and vertical structure in larval abundance : the potential roles of biological and physical processes
… advected to potential adult habitats by inner-shelf circulation such as wind-driven upwelling and downwelling. This research capitalized on two sets of larval concentration time series, collected by moored zooplankton pumps, and complemented by synoptic hydrographic time-series data. High …

Circulation of the Western Antarctic Peninsula: Implications for Biological Production
… western Antarctic Peninsula (wAP) continental shelf is characterized by large persistent populations of Antarctic krill (<em> Enphausia superba</em>) and by regions of enhanced concentrations of marine mammals and other predators (hot spots). This study focused on understanding the role of …

Modeling the Seasonal Sea Ice Cycle in the Ross Sea, Antarctica
… ice model (CICE) and thermodynamically to an ice shelf is used to investigate Ross Sea seasonal sea ice cycle, polynya dynamics, distribution and transformations of continental shelf water masses, and bottom water formation. Daily atmospheric forcing is from the ECMWF ERA-40 dataset, and for a …

Clay Mineralogy and Organic Carbon Associations in Two Adjacent Watersheds, New Zealand
… in clay mineralogy associated with cross shelf transport reveal chlorite increases at the expense of illite off the Waiapu shelf. A downcore study was conducted on the Waipaoa shelf to examine temporal variability. The sediments in the flood layer and below resemble the river suspension, …
