Abstract Continental slopes are the edges of continental blocks, the zones of change from continental crust to oceanic crust. They are critical links in the chain of sedimentary processes that eventually carry sediment to the true ocean basin floor. In spite of their importance, until recently continental slopes have been largely ignored

Pogonophora on the New England Continental Slope
Science, 1963Two species of Pogonophora on the continental slope off southern New England are reported. Two species were found: Siboglinum ekmani Jägersten and Siboglinum sp., an undescribed species. The density of both species combined, at 366 m, was 30 per square meter and at 567 m depth, it was 25 per ...

Sediment partitioning, continental slopes and base‐of‐slope systems
Basin Research, 2016AbstractDeciphering the role slope topography plays in partitioning sediment on siliciclastic continental slope and base‐of‐slope systems helps our understanding of slope depositional processes in significant ways: (1) by validation of large‐scale depositional process models for continental margins, (2) by validation of numerical basin‐scale ...

Erosion of canyons in continental slopes
Geological Society, London, Special Publications, 2005AbstractSonar images of the Atlantic USA continental slope reveal an eroded landscape that appears remarkably similar to subaerial landscapes eroded by surface runoff. Analysis of multibeam data reveals that they are also similar in a number of quantitative aspects, such as similar scaling between channel gradient and contributing area, they show Hack ...

Slope Stability of Continental Megalandslides
2013Continental megalandslides, although rare, are found in various morphological settings including mountain fronts and valley sides with steep (> 30°) to shallow (

Topographic Waves over the Continental Slope
Journal of Physical Oceanography, 1988Abstract Current meter data taken during a one-year period over the continental slope and upper rise in three cross-isobath sections have been examined for energy distribution, coherence, and phase propagation of topographic waves. A peak at 15 days is present in the energy preserving spectrum of the near-bottom currents on the rise and slope.

Occurrence of Pyrosoma on the Continental Slope
Nature, 1960Hurley and McKnight1 have reported that the pelagic tunicate Pyrosoma atlanticum atlanticum rests on or swims just above the sea-floor at a depth of 160–170 metres. Indirect observations made on this species in the course of a line-fishing survey of the fishes of the south-eastern Australian continental slope2 corroborate the concentration of this ...

Characteristics of Continental Shelves and Slopes
AAPG Bulletin, 1965One of the most important and interesting geological questions awaiting solution is that of the origin of continental shelves and slopes. Just as for other geological features, more than a single origin is involved for different areas or for different times.

Geomorphic Evolution of Continental Terrace (Continental Shelf and Slope)
AAPG Bulletin, 1952Prevailing concepts regarding the geomorphic modification of the continental margin rely on the theory of wave base and its corollaries, namely, a wave-built terrace, topset shelf beds, and steep foreset slope beds. These views are rejected because they are theoretically unsound and they do not adequately explain the form of the terrace as revealed by ...

Line-Fishing on the Continental Slope
Journal of the Marine Biological Association of the United Kingdom, 1964A method of line fishing in depths of over 1000 fm has been used successfully from R.V. ‘Sarsia’ on the continental slope. The catches have been mainly black squaloids but two brotulids, truly abyssal fishes, have also been taken.
