Seismic lines were acquired to map the shallow sedimentary structures. Seismic velocity analyses suggest a consistent regional velocity-depth trend on the slope, east of the Mackenzie Trough, with deviations noted at an upper erosional unconformity associated with mega-scale glacial lineations and at the base of the Shallow Bay Formation. Data acquired in the Mackenzie Trough region suggest a different velocity-depth trend, with the region being marked by a large erosional unconformity. Velocity analyses suggest a removal of up to 600 m of overburden. In deeper water, a bottom-simulating reflector is characterized by the presence of free gas and a low velocity zone. The data allowed analyses of fluid expulsion features and determine that the source of mud extruded on the seafloor was from depths of up to 3 km"--Provided by publisher. |
