Erosion by biological activity in two New England submarine canyons
TLDR
In this paper, Deepstar 4000 observations from Block and Corsair Canyons indicate that erosion is pre predominantly biological, and no evidence for large mass movements in the axis area or recent turbidity current activity was observed in either canyon.Abstract:
Observations from Deepstar 4000 in Block and Corsair Canyons indicate that, at present, erosion is pre predominantly biological. No evidence for large mass movements in the axis area or recent turbidity current activity was observed in either canyon.read more

Borings As Trace Fossils, and the Processes of Marine Bioerosion
TL;DR: Marine borers are nearly ubiquitous in the modern seabed and their distinctive excavations provide abundant potential trace fossils, and their general erosional activities (bioerosion) are important factors in marine sedimentation and benthic ecology as discussed by the authors.

Modification of sediment permeability and shear strength by two burrowing invertebrates
P. S. Meadows,J. Tait +1 more
TL;DR: The correlations between shear strength and permeability and between permeable and water content were affected differently by the two species and there were few partial correlations between the variables.

The landslide problem
Ganapathy Shanmugam,Yuan Wang +1 more
TL;DR: The use of the general term “landslide”, with a built-in reference to a sliding motion, for all varieties of mass-transport deposits (MTD), which include slides, slumps, debrites, topples, creeps, debris avalanches etc. in subaerial, sublacustrine, submarine, and extraterrestrial environments has created a multitude of conceptual and nomenclatural problems.

Submarine fans: A critical retrospective (1950-2015)
TL;DR: Submarine fans have been extensively studied in the literature as mentioned in this paper, with the most significant contributions coming from the 1970s to the 21st century, where the main focus has shifted from submarine fans to submarine mass movements, internal waves and tides, and contourites.
Journal ArticleDOI
Morphologies of knickpoints in submarine canyons
TL;DR: In this article, a simple bed erosion model is presented, which is analogous to the detachment-and transport-limited erosion models of fluvial geomorphology, which predict that the channel topography should advect or diffuse (smooth out), respectively.
