path of the hurricane eye. A 50-m. -thick 

 layer of isothermal water lay on the surface 

 at distances of about 150 km. either side of 

 the path. A strong divergence developed sea- 

 ward of the Mississippi Delta. Surface cur- 

 rents flowed to the east and west on respective 



sides of the delta. Although nnodified to some 

 degree, these latter features were still present 

 10 days after the stornn had passed over the 

 northern shelf.

LIBRARY 



More than 600 volumes of books and journals, 

 and 2,200 reprints and miscellaneous publica- 

 tions were added to the library collection 

 during fiscal year 1966. Additions included 

 microform and reprint editions of selected 

 out-of-print publications and a number of 

 translations. Additional shelving and equipment 

 have been acquired to accommodate the ex- 

 panding collection. 



The use of library services amd the library 

 resources increased markedly during the year. 

 In addition to current activities, special proj- 

 ects have included (1) revision of the subject 

 index for reprints received before the current 

 listing to consolidate them with the subject 

 catalog in use; (2) compilation of an author 

 index for certain series of Service publica- 

 tions; and (3) preparation of a selected subject 

 index for the Laboratory supply of reprints. 

 Duplicate amd surplus publications were for- 

 warded to other laboratories upon request. 

 The weekly list of current acquisitions was 

 continued for distribution to the staff and to 

 selected laboratories. 



The librarian has continued to assist other 

 laboratory libraries in Region 2 in methods 

 and procedures.
