Near-surface geology and sediment-failure geohazards of the central Scotian Slope

Siliciclastic slope deposits from the Cretaceous Abeokuta Group, Dahomey (Benin) Basin, southwestern Nigeria

“…This analysis supports the deductions on slope environments and facies building blocks of Galloway (1998). Similarly, it compares favourably with outcropping slope and deep-sea sedimentary features recognized by other workers (Selley, 1985;Hiscott and Aksu, 1994;Harrison and Graham, 1999;Peter, 2002;Browne and Slatt, 2002;Beabouef, 2004;Mosher et al, 2004). The results of those studies are compared with this study.…”

“…Channels have been described as prominent features on the slope and base of slope settings and exhibit similar characteristics with their subaerial counterparts (Schumm, 1993). The morphologies of the channels delineated on some of the present outcrops are similar to smaller canyons, gullies and upper slope escarpments of Mosher et al (2004), recognized on the Scotian slope.…”

Geomorphologic features related to gravitational collapse: Submarine landsliding to lateral spreading on a Late Miocene–Quaternary slope (SE Crete, eastern Mediterranean)

“…They normally show a wide range of morphologies, which reflect differences in the nature of substrate strata prior to failure, relative inertia of downslope transport, as well as complex interactions between failed strata and the slope morphology (Locat, 2001;Mosher et al, 2004;Lee et al, 2006;Bull et al, 2008). However, one of the principal limitations when using indirect geophysical methods to assess sediment failure relates to the impossibility of correlating, from headwall to toe regions of landslides, the acoustic characteristics of failed strata with their corresponding petrophysical properties.…”

The Kongsfjorden Channel System offshore NW Svalbard: downslope sedimentary processes in a contour-current-dominated setting

“…Fig. 5h; compare with [44]). As the study area is located close to the SFZ, we also regard the release of tectonic stress (compare with [55]) as a potential trigger for failures on the sidewalls.…”

“…[29,37,43,44,48,58,71,73]). In this study, we present swath bathymetry and subbottom profiler data from a channel system on the continental slope off NW Svalbard.…”
