Sediment-starved margins occur in the eastern Qiongdongnan area because of a very wide shelf and insufficient sediment supply.
The modern Niceto canyon head is connected landwards to a delta system that stretches across a 1 km wide shelf.
A 2-cm wide shelf with small wells was mounted in the front of the slit, but outside the box wall.
The Bay of Bengal is bordered to the north by a wide continental shelf that narrows to the south and by slopes of varying gradient on the northwest, north, and northeast, all cut by canyons from the rivers.
The performance of coastal altimetry over a wide continental shelf is assessed using multiple-year ocean current observations by moored Acoustic Doppler Current Profilers (ADCP) and high-frequency (HF) radar on the West Florida Shelf.
The semi-enclosed basin of the Golfe d'Arguin (Northwest Africa) is present on a wide, shallow shelf, bordering the Sahara desert, in a stable tectonic context.
France's Atlantic coast north of the Gironde estuary is a succession of rocky and sandy shorelines, including a sizeable intertidal zone, a wide continental shelf, and two major estuaries (Loire and Gironde).
Little dilution of the carbonate produced in situ is generally promoted by a wide "epicontinental" shelf, subdued topography of the adjacent mainland, the predominance of limestone outcrops, and an arid climate.
The present activity of deep-sea sedimentary processes is linked to the existence of a direct connection between the Congo River estuary and the Congo canyon head that allows relatively continuous sediment feeding of the deep-sea environment, in spite of a wide continental shelf (150 km).
