The mechanisms controlling the temperature and salinity structure of shallow continental shelf seas have been understood for over thirty years, yet knowledge of what drives their large-scale circulation has remained relatively unknown. Here we describe a decade long programme of measurements, using satellite-tracked drifting buoys on the northwest European shelf, to draw attention to a. A general ocean circulation model is used to study the dynamics of the cross-shelf circulation in the Yellow and East China Seas in winter. The model results show that the shelf circulation in.

the shelf seas account for ∼9% of the total area of the global ocean and less than % of the volume. The shelf seas have an influence and importance quite out of proportion to these numbers. The shelf seas act to dissipate a high proportion of the mechanical energy input to the ocean. All papers from M.J. Bowman and W.E. Esaias's () book, "Ocean Fronts in Coastal Processes" were included along with the papers in the Royal Society of London's Circulation and Fronts in Continental Shelf Seas (Royal Society of London, ).

Get this from a library. Circulation and fronts in continental shelf seas: a Royal Society discussion held on 25 and 26 February [J C Swallow;]. All of the shelfbreak zones are graced by thermohaline fronts.

The fronts are progradational on the west and south-eastern coasts and retrogradational on the northeastern shelf. These fronts are an integral ingredient of all aspects of physical processes at the shelfbreak strip. Variations in the level of tidal stirring divide the shelf seas, during the summer regime, into well mixed and stratified zones separated by high gradient regions called fronts.

A well‐defined class of fronts occurring in the shelf seas around the United Kingdom during the summer months marks the boundary between stratified and vertically mixed regimes. The occurrence of these fronts may be interpreted in terms of the distribution of available turbulent kinetic energy from the tidal currents and wind stress and the buoyancy flux input at the by: Bowers, D.

Geographical variations in the seasonal heating cycle in northwest european shelf seas Continental Shelf Research 10 Cited by: It also discusses the extent of each province, continental shelf topography, and tidal and shelf-edge fronts, defining characteristics of regional oceanography, the response of the pelagic ecosystems, and regional benthic and demersal ecology.

A two-dimensional numerical model is formulated to simulate long-term mixing in the coastal waters over the European Continental Shelf. By using both tidal and wind-driven components, the mean circulation over this region is computed and is shown to be in good agreement with earlier estimates from (i) modelling studies, (ii) observations of residual flow, and (iii) observations of mean sea.

First, CDW is driven onto the shelf at least partially due to momentum advection and the curvature of the shelf break. Then, the general shelf circulation pulls the CDW into the interior.

Scotland's position on the UK Continental Shelf means that the seas around Scotland are directly affected by oceanic circulation. The steep bathymetry of the continental slope acts as a barrier between oceanic regions and the shelf sea systems, reducing the amount of water that can travel from the deeper waters of the North Atlantic into the shallower waters on the continental shelf.

Introduction to the Physical and Biological Oceanography of Shelf Seas In this exciting and innovative textbook, two leading oceanographers bring together the fundamental physics and biology of the coastal ocean in a quantitative but accessible way for undergraduate and graduate students.

Shelf. The journal provides a unique forum, unifying the multidisciplinary approaches to the study of the oceanography of estuaries, coastal zones, and continental shelf seas.

It features original research papers, review papers and short communications treating such disciplines as zoology, botany, geology, sedimentology, physical oceanography.

[1] The mechanisms controlling the temperature and salinity structure of shallow continental shelf seas have been understood for over thirty years, yet knowledge of what drives their large‐scale circulation has remained relatively unknown.

Water masses of shelf seas are generally more buoyant than the oceanic water offshore, because freshwater (and hence buoyancy) is supplied by rivers, or in some locations by the equatorward coastal flow of light polar water.

Shelf sea hydrography is therefore often characterized by buoyancy-driven, longshore currents in which the sea surface slopes. The coastal ocean meets the deep sea at the continental shelf edge.

Questions of global change entail elucidation of the processes that determine the quantities, transformation and fate of materials transported between the shelf and ocean, the measurement and definition of exchange processes, and the development of prognostic models of exchanges.
