Except for the CaC03 content and the specific gravity which tend to remain 

 constant in the sediments, other properties show a variation in magnitude which is 

 generally dependent upon the area from which the sediment sample was obtained. 

 These variations will be discussed below under the appropriate sedimentary category. 



Near-flank Sediments 



Sediments of the near-flank category are represented by the following samples; 



62-1 62-23 62-37 



62-4 62-24 62-38 



62-6 62-25 62-39 



62-9 62-26 62-57 



62-10 62-28 62-58 



62-14 62-32 61-1 



62-15 62-33 61-9 



62-19 62-34 61-10 



62-20 62-35 61-18 



62-21 62-36 



An examination of Figure 4 shows that these samples are all located on the flanks or 

 walls bounding the TOTO and were collected from water depths between 250 and 

 1 ,243 meters. 



Sediment color in the near-flank area is decidedly darker compared to other 

 areas in the TOTO and is dominantly yellowish gray (5Y7/2) grading to a lighter 

 greenish gray (5GY8/1). (Geological Society of America Rock-Color Chart code). 

 The most striking property exhibited by these cores, except for a few from the 

 southern flank of the cul-de-sac. Is the smooth, even color and texture with depth 

 In the sediment. Figure 7 presents a longitudinal cross section of selected near- 

 flank cores, and, from this, the general homogenuity of particle grain size and 

 sediment color Is evident.
