ABSTRACT 



This report describes a study of the occurrence, speed, and 

 direction of short-term changes in water temperature near 

 Texas Tower No. 4 off New York. Measurements made 

 during two-week periods in the fall of 1959 and the spring 

 of 1960 reveal common occurrences of internal solitary wave 

 forms indicated by temperature changes at fixed levels of 

 several degrees centigrade within several-minute intervals. 

 Internal temperature wave forms observed in both seasons 

 were typically moving onshore at speeds ranging from 0.75 

 to 1.30 knots. Comparison of observed speeds with values 

 calculated from internal solitary wave theory exhibits reason- 

 able agreement considering the limitations of the field 

 experimental phase of the study. 



The data upon which this report is based were collected by the author while 

 Head, Special Research Group, Hydrographic Office. The manuscript was 

 prepared by the author while associated with the Department of Oceanog- 

 raphy and Meteorology, Agricultural and Mechanical College of Texas.
