Three additional fields have already been added to the day sheets: 

 time of beginning of observations (65-68) , time of end of observations 

 (69-72), and special parametric analysis (73-75). The times of begin- 

 ning and end of observations coincided with the times of sunset and 

 sunrise on the Cromwell cruises, but in other studies observations may 

 begin or end earlier or later. 



In the pilot study, density figures were computed on the basis of a 

 full day's observations. In future studies, however, it may be 

 necessary to determine abundance in areas that were covered in less

than a full day. The new special parametric analysis (SPA) field 

 will be introduced on the revised day card for that purpose. An 

 entry in this field will "flag" for restricted abundance analysis all 

 observations made within the time segment represented on the day 

 card. The use of all combinations of punches in each column (10 

 digits and 26 letters) permits designation of 36 3 (46,656) different 

 areas. 



On the day card the number of hours of observation, the actual 

 times of observation, and the distance travelled within the designated 

 area must be fractionized by entering them on two or more "fractional"
