FOREWORD 



Of great importance to a variety of naval operations is the knowledge 

 of density distribution in the ocean at particular points in space and 

 time. The field studies conducted at Texas Tower No. 4 in support of 

 the Antisubmarine Warfare Environmental Prediction System (ASWEPS) 

 were designed to detect and provide a fund of field data for the analysis 

 of regular and irregular variations in temperature structure beneath 

 the water surface. The primary emphasis of this report is on anomalous 

 short-term transitions giving the appearance of internal solitary waves.
