Abstract:

San Miguel Passage is characterized by sediment dispersion to the southeast. The energy level is highest in the center of the passage and is there a gradual decrease in energy towards the perimeter. Santa Cruz Channel is more complex. A lobe of coarse sediment, part of which appears to be relict, in the northern section of the channel shows dispersion to the east. However, finer sediment is moving into the southern part of the area from the east, where it is intercepted by the head of Santa Cruz Canyon. All of the passages are considered to be at or near a state of dynamic equilibrium with respect to mechanical energy input because of the thin veneer of sediment present and the high degree of sorting exhibited by the sediment.
