The relationship of internal waves, with 2-to-20-minute periods, to surface 

 waves was investigated. It was found that (1) the interaction between amplitude- 

 modulated swell and internal waves may create internal waves of 2-to-20-minute 

 periods; (2) internal waves due to amplitude -modulated swell have the same char- 

 acteristics as the modulation; and (3) the resonance process is most efficient in 

 the case of a modulation traveling in the same direction as the carrier wave of 

 a swell.
