Figure 9. The sea floor at 1000 meters depth south of Capri. Figure shows appearance of bottom immedi- 

 ately to the right of the ballast pile shown in figure 8. The undisturbed sea floor sediment appears 

 "gravelly." This feature is possibly due to the delicate sculpturing activity of the numerous isopod 

 Crustacea. 



Figure 10. The sea floor at 1000 meters south of Copri. Bits of detritus, mostly from the littoral growing 

 eelgrass, Posidonia^ was often seen. Low mounds, presumably of biological origin, are silhouetted in the 

 background.
