only sound speed. No sound speed relation to other physical or compositional 

 properties was determined in this study. Future use of the DOSP, including the 

 application of density and/or porosity gages (Erchul, 1971; Rose, 1971) may 

 provide sufficient data to characterize the sediment without the need for 

 recovering a sample. 



ACKNOWLEDGEMENT S 



The DOSP is being co-developed under contractual agreement between URI and the 

 U.S. Navy Underwater Systems Center, New London, Connecticut. The authors wish 

 to thank Dr. E. Towle of the Caribbean Research Institute, Col. J. Smith of the 

 Research Triangle Institute, and personnel of the TEKTITE II office, U.S. 

 Department of the Interior, for their cooperation in providing use of the 

 R/V ADVANCE II and transportation of personnel and equipment for this investi- 

 gation.
