Bathymetry of the South African Continental Shelf
… of which lies the prominent South African continental shelf, a relatively flat extension of the onshore coastal plain. The continental shelf is host to major mineral and petroleum deposits, home to South Africa’s major sea fisheries and full of navigation hazards. Therefore, knowledge of …

Cooling and internal waves on the Continental Shelf
… of geostrophic flows and inhibits the cross-shelf flux of heat. The vertical mixing is eventually suppressed by the advective transport of cold, dense water offshore. Once this happens, alongshore geostrophic flows form, and become baroclinically unstable. The surface heat flux is then …

Palaeogene ostracods from the South African continental shelf
92 cytheracean species, representing 44 genera are recorded from the Palaeogene Agulhas Bank and west coast margin of South Africa. 11 genera and 3 species are common with the Upper Cretaceous faunas. 12 genera (18 species) are left in open nomenclature. The following genera are represented:- …

The dynamics of mean circulation on the continental shelf
… the order 5 cm/sec has been observed on several continental shelves, e.g. in the Middle Atlantic Bight and in the Weddell Sea. A theoretical model is developed to explore the driving mechanism of this mean circulation. In the model, the velocity field is decomposed into a depth-independent bottom …

Assessing Dynamic Seabed Change on the Scottish Continental Shelf
… analysis of dune morpho dynamics on the Scottish continental shelf is essential to facilitate the predicted expansion of offshore renewables in this area. This thesis therefore aims to investigate dune mobility on the Scottish continental shelf that is driven by energetic hydrodynamics which may …

Tidal band current variability over the Northern California continental shelf
… of the tidal band current fluctuations over the continental shelf off northern California. The term "tidal band" is used here to denote fluctuations with periods from about one-half to one day, including all the major diurnal and semidiurnal tidal constituents. The semidiurnal frequency is …

The Response of an Idealized Continental Shelf to Atmospheric Forcing
<p>The response of continental shelf water to cooling and wind stress is investigated using a two-dimensional numerical model. The topography of the east coast continental shelf was idealized by connecting a shallow (50 m) rectangular nearshore basin to a deeper (100 m) rectangular offshore basin. …

Ocean circulation and dynamics on the west Antarctic Peninsula continental shelf
… program on the western Antarctic Peninsula continental shelf are used to characterize the ocean circulation and its connection to fresh water and heat fluxes on the shelf. Mean velocities on the shelf are of the order of 5 cm/s or less. Tidal motions are dominated by the M2 and S2 …

Mechanisms of turbulent mixing in the Continental Shelf bottom boundary layer
… in the late summer of 1996 on the New England shelf. The energetics of the turbulent fluctuations are investigated by testing simplified budgets for turbulent kinetic energy and scalar variance. The turbulent kinetic energy budget is locally balanced while the scalar variance budget is not, …

The Microbiostratigraphy of the Paiaeocene of the Northwest European Continental Shelf
… laid down under moderate palaeodepths (c. middle shelf) and probably representative of the socalled "outer sublittoral" biofacies of King, 1983. Evidence for progressive deepening of water depth towards the north of the area and mto the Silver Pit Basin was noted. The microfaunal assemblages from …

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 …

Fish population and behavior revealed by instantaneous continental-shelf scale imaging
