FOREWORD 



Oceanic thermal structure prediction for support of Fleet 

 operating units is the prime objective of the Antisubmarine War- 

 fare Environmental Prediction Services (ASl^PS) program. Current 

 prediction techniques which are designed for deepwater areas are 

 not necessarily suitable for the shallow-water areas inshore of 

 the 500-fathom isobath. Since 1967 a series of investigations 

 has been conducted in selected areas to obtain data necessary for 

 modifying deepwater techniques for use in shallow-water areas. 

 This report, the second of a series, describes thermal structure 

 in the Virginia Canes Operating Area during September and October 

 1967. Subsequent reports will describe thermal structure in the 

 VACAPES Op-Area and in other shallow-water areas.
