8. Turbidity currents originate on the upper flanks of the channel, flow down 

 slope at high velocity within the gullies, and distribute the sediment load locally on 

 the channel floor. 



9. Frequency of the turbidity flows is greatest in the cul-de-sac area and 

 becomes less frequent northward in the channel. Rate of sediment accumulation is 

 highest on the channel flanks and becomes less northward from the cul-de-sac along 

 the channel axis. 



10. Ultimate bearing strength of the sediment is lowest in the cul-de-sac and 

 near-flank areas, highest in the axial area, and can be shown to follow the same 

 trend as the organic carbon and water content of the sediments. 



1 1 . Bottom photographs show a paucity of benthic fauna, and, in general, a 

 relatively featureless, unconsolidated ooze covers the channel floor. 



12. The photographs reveal a bare rock outcrop at 1,000 fathoms in the center 

 of the channel off Fresh Creek. Features in the outcrop indicate subaerial erosion 

 of the exposure at some earlier geologic time. 



13. Ripple marks present in some of the bottom photograph suggest a bottom 

 current at 1 ,000 fathoms of at least 0.3 to 0.7 knot.
