An example of a sediment analysis that is primarily biological and 

 consists of a listing of the species whose skeletal remains have been 

 identified in the sample is provided by Figure 9. 



Figure 6 provides examples of samples reported in Swedish and 

 Russian publications. A long core from one of the deepest ocean trenches 

 is reported by the Swedish Deep Sea Expedition (Code 214) and gives 

 a field description of the color and grain size classification, a descrip- 

 tion of the origin of the nnaterial, and the percentage of grains in 

 various size classes at different levels in the core. The Russian 

 publication (Code 262) reports both a core and a dredge sample taken 

 at the same location in the Barents Sea. In this example the information 

 was abstracted from several widely separated pages in the publication, 

 translated, and assembled on one card, a very laborious task. 



Another example of treatment of Soviet data is shown in Figure 8. 

 Here the Russian has been transliterated and translatedfor this report; 

 however, on most of the data cards the information appears in the 

 Cyrillic form and has been neither transliterated nor translated. 

 The widespread ignorance of Russian among Americans greatly limits 

 the use of such data except where translation facilities are available. 



Figure 7 is an example of a long description of a sample in Portu- 

 guese. Here the language is less of a barrier to English speaking 

 researchers than in Figure 8 but still may cause some difficulty for 

 those unfamiliar with Romance languages. 



Another problem in handling sediment data is the reproduction of 

 graphic portrayals of samples (Figure 13). Placing such information on 

 individual sample data cards is complicated further when the original 

 is in color, which cannot be reproduced photostatically. 



B. Organization of data file -- The data cards are filed geographic- 

 ally by using the Marsden square system (Figures 14 and 15). The 

 first order division is by 10-degree squares, the second by 5-degree 

 squares, and the third by 1-degree squares. Five-degree square divi- 

 sions have been used to date in only a few 10-degree squares in which 

 there are too many cards for convenient manual sorting. It has not 

 been necessary as yet to use the 1-degree square breakdown. The 

 Marsden square number is entered on the upper right-hand corner of 

 the data card.
