the distribution of the work among the different members 

 of the staff and the amount of time required for each sub- 

 ject of investigation. It should be stated that although 

 the tables show the number of hours per day, two days 

 are required to complete a schedule since magnetic and 

 oceanographic stations are made on alternate days, in- 

 cluding Saturdays and Sundays. 



The number of hours given in the above tables is 

 approximate only and, of course, subject to considerable 

 variation. In order to have only eight hours per day per 

 man, the time required perhaps in all cases has been 

 underestimated. It is doubtful if the work performed on 

 board in one day could be accomplished in sixty-four 

 working hours, even if there were no trouble with appa- 

 ratus or delays due to other causes. As a consequence, 

 the average working day is considerably more than eight 

 hours. 



Discussion of Scientific Program 



Navigation. - -Whenever weather conditions permit, 

 latitude observations are taken daily at noon and longi- 

 tude in midmorning and midafternoon. Occasionally stars 

 are used for both latitude and longitude. All observations 

 are made and computed independently by two members 

 of the scientific staff (and by the first officer). Dead 

 reckoning involves a great deal of work and the amount 

 varies with the number of scientific observations made. 

 Whenever a scientific observation is made or a sample 

 collected, the time and log reading are recorded. The 

 position for each observation is computed later from the 

 previous and subsequent astronomic positions. Also a 

 certain amount of time is required for laying out courses 

 and other routine work. Navigation requires a total of at 

 least eight hours per day from two or three persons.
