... Abstract When icebergs touch and scour through unconsolidated seafloor sediment the keel ice may fracture and crush, creating individual ice blocks that may rotate independently of each other under confining pressure. Blocks of ice also may be forced into and embedded in the seafloor beneath...

... for gouge depths within local neighborhoods. Seafloor roughness maps can also be generated to highlight the spatial variability of seafloor disturbance and, in a relative sense, visualize the ages of different gouges if certain assumptions are satisfied. We illustrate application of the method using...

... Abstract Arctic circulation drives multi-year sea ice against the Canadian Arctic Archepelago, making this margin one of the toughest regions in the Arctic Ocean to survey. Yet Canada had a need to map the seafloor in this region as part of its Extended Continental Shelf Program. One...

... have discovered substantial methane gas plumes exiting the seafloor along the Arctic Ocean margin, and the plumes appear at depths corresponding to the upper limit of a receding gas hydrate stability zone. It has been suggested that these plumes may be the first visible signs of the dissociation...
