C. FUTUEE PLANS 



1. Revisions of Log Sheet and Manuals 



The method of processing BT data, which has "been described 

 in this report, eliminates all hand copying of data onto the finished 

 print, with the single exception of the key number used for filing. 

 This must be added to the space provided in the upper right hand comer 

 of each print. The method, however, places a greater hurden on the 

 accuracy and readability of the log sheet data. Errors on the log 

 sheet could be corrected in the older process before or during copying 

 data to the backs of the hathythermograms . The newer method requires 

 that all corrections he made prior to photographing. Obviously the 

 best place to make corrections is at the source. To this end the oh- 

 server in the field must be provided with a precise set of instructions 

 and all the codes and tables necessary to complete the log sheet 

 properly. In addition, the log sheet information must be arranged in 

 the easiest manner for the analyst to read the film or the print 

 (fig. 9) and also to enable the E.A.M. punch -card operator to trans - 

 scrihe all the information in the desired order. 



In order that these things may be accomplished, the BT log 

 sheet, Oceanographic Log Sheet - B, PENC-KHO II89 , has been revised. 

 Each pad of 100 log sheets is provided with a cover Jacket containing 

 instructions for filling in the various columns and marking the slides. 

 The jacket also contains all necessary codes and tables for making the 

 meteorological entries. Examples of the entries are shown on a sample 

 log sheet. H. 0. Pub. Wo. 606-C, Bathythermograph Observations, is 

 being rewritten and modernized to bring it into agreement with the new 

 log sheet and the instructions contained in the new edition of E. 0. 

 Pub. Wo. 607, Instruction Manual for Oceanographic Observations. These 

 instructions will be much more detailed and specific than previous ones. 

 It has been found that where a choice of observational method was 

 allowed such as injection or bucket sea temperatures and Beaufort or 

 knots for wind, the observer rarely stated which he used. By elimin- 

 ating choice much time will be saved that is now spent in determining 

 which method the observer used. It is hoped that by providing all 

 observers with these tools, the time spent in receding and correcting 

 log sheets can be considerably reduced, which in turn will greatly 

 reduce the time required for processing each cruise.
