RECOMMENDATIONS 



1. Continue combined photographic, sediment, water- 

 sampling, water-current, and temperature studies at ocean 

 stations to improve the reliability of microroughness pre- 

 dictions for the sea floor. 



2. Construct microprofiles of the sea floor covering 

 vertical, horizontal, and slope measurements of micro- 

 relief for correlation analyses. The principles of photo- 

 grammetry should be applied if stereo cameras are utilized 

 to obtain the needed data. 



3. Encourage the study of micro and intermediate 

 relief as an aid to the future operation of submersibles 

 and tracked vehicles on the sea floor. 



4. Encourage further use of portable, subbottom, 

 acoustic profiling methods to help establish the relation- 

 ships of microrelief at the sediment-water interface to 

 deeper substrata features. 



ADMINISTRATIVE INFORMATION 



Field work for this project has extended over the 

 past 10 years on an intermittent basis. This report was 

 prepared under BUSHIPS Problem SR 104 03 01, Task 0539 

 (NEL Problem L4-1 (now L40161)). It was approved for 

 publication on 26 April 1966. 



Many scientists and crew members on numerous 

 oceanographic cruises helped the author lower cameras, 

 collect samples, and process film; they are too numerous 

 to be named here. Special thanks are due to R. E. Boyce 

 for the preparation of photographic grid scales and help in 

 the analysis of bottom photographs; to D. Muerdter for 

 mathematical assistance; and G. L. Prible, D. Bachman, 

 and Mrs. Renee Forsyth for the preparation of maps and 

 illustrations.
