Quantitative fish survey of the submarine canyons of the iSimangaliso Wetland Park
… studies of fish species associated with the submarine canyons of the north east coast of South Africa. These canyons offer protection to coelacanths Latimeria chalumnae, fish of commercial importance, and a number of protected and endemic species. A fish survey was conducted by remotely …

Controls on sedimentation in submarine canyons: Nazare, Setubal and Cascais canyons, West Iberian Margin
… one of the most comprehensive studies on submarine canyons yet. It<br/>integrates data on the geology, geochemistry, sedimentology and oceanography of the<br/>Nazaré, Setúbal and Cascais canyons, west Iberian margin, in order to constrain the<br/>processes and controls of past and present …

Observed circulation and inferred sediment transport in Hudson Submarine Canyon
Velocity and temperature time series from Hudson Submarine Canyon and hydrographic surveys of seven canyons of the Middle Atlantic Bight indicate that the effects of storms, tides, and incoming internal waves are intensified in submarine canyons. Storms with strong eastward and westward wind stress …

Abyssal mixing from bottom boundary effects in Mid-Atlantic Ridge flank canyons
… Experiment, suggest that mixing in the flank canyons of the Mid-Atlantic Ridge generated when strong mean flows interact with the many sills and constrictions within the canyons may represent a dynamically important amount of abyssal mixing. The energy pathways and mechanisms of this mixing …

Characterization of the East China Sea Continental Shelf Circulation Northeast of Taiwan surrounding Mien-Hua Canyon
Submarine canyons have a proven and direct influence on continental shelf circulation and flow dynamics, especially in relation to western boundary currents. There are two key circulation features northeast of Taiwan on the East China Sea continental shelf: (1) the cold dome, a cyclonic feature …

Multi-Disciplinary Analyses of Outcropping Late Cretaceous Clinoform Stratigraphy, Magallanes Basin, Chile
… basins. Clinoforms, shelf-edge deltas, submarine canyons, and deep-water channels are central components of these systems, yet their stratigraphic architecture, sediment-routing behaviour, fluid trapping potential, and influence on organic matter preservation are commonly studied …

From the Foreland and Retroarc Thrust Belts to the Mantle Transition Zone: First Multi-Scale Retrodeformable Transect of the Active 90 mm/yr Taiwan Arc-Continent Collision
… eastern Taiwan, which is one of the largest submarine canyons around Taiwan and results from the <1 Ma uplift of the retroarc thrust belt and submarine erosion. Chapter 2 presents the precollisional architecture of the Luzon arc and the thin-skinned structure and stratigraphy of the deforming …

Coastal sources of estuarine inflow
… of deep inflow in both experiments, suggesting submarine canyons may be an important conduit of inflow under all wind stress conditions. The results suggests that wind stress may be less important than other shelf dynamics on time scales longer two weeks.

The Ecology of Cuvier’s beaked whale, Ziphius cavirostris (Cetacea: Ziphiidae), in the Bay of Biscay
… areas over continental shelf slopes and submarine canyons. The variety of modelling techniques used to identify the habitat preferences and to predict areas of high suitability for Cuvier’s beaked whale in the Bay of Biscay all proved advantageous. On a global scale, techniques such as …

Seismic stratigraphy and tectonic evolution of a transform continental margin, offshore Sierra Leone
… and the development of extensive lowstand submarine fan systems. Some models of slope failure and synchronous development of submarine channel and canyon systems have been developed for this basin. Extensional slope failure is controlled by pre-existing structural trends. Submarine canyons …

Studies of deep-sea sedimentary microtopography in the North Atlantic Ocean
… irregularities on the sea floor, such as submarine canyons, or by instabilities in the flow of deep, contour-following currents. Sediment waves develop where there is an abundant supply of sediment and steady mean currents. Waves appear to migrate upstream where tidal current fluctuations …

The application of machine learning and 3D photogrammetry for cold-water coral habitat classification in the NE Atlantic
Cold-water coral reefs are complex structural habitats that represent one of the most important deep marine ecosystems. As three-dimensional habitats with high structural complexity, they provide ecosystem services that influence species abundance and biodiversity, being indicators of ecosystem …
