Longitudinal cross sections of cul-de-sac cores are presented in Figure 9, and, 

 from this figure, the cores collected from the central, flat reaches of this area can 

 be seen to consist almost in equal part of turbidites and sediments laid down particle- 

 by-particle from the water column. Turbidites in this area accounted for well over 

 40 percent of the sediment column sampled. In the cul-de-sac it was difficult to 

 ascertain the upper contact of turbidites with the overlying sediment; hence, it Is 

 possible that a larger percentage of the sediment column is due to turbidity currents 

 than the data reveals. 



Many of the cul-de-sac cores gave off a strong H2S odor, and the few pH meas- 

 urements taken were less than 7.0.
