RECOMMENDATIONS 



1. Conduct further studies of oxygen consumption of 

 siphonophore floats, especially during secretion of carbon 

 monoxide. Such data should provide a better idea of the 

 energy likely to be available for countering the collapsing 

 effects of high pressure, and of probable refilling times. 



2. Provide possible chemical substrate materials to 

 floats in an effort to determine maximum rates of carbon 

 monoxide secretion. 



3. Conduct procedures 1 and 2, above, in small pressure 

 chambers to directly determine the effects of elevated pres- 

 sures on respiratory rate and gas production rate. 



4. Utilize pressure chambers in a study of bubble re- 

 lease by siphonophore floats; attempt to learn size and 

 frequency of bubble release as the pressure is reduced by 

 steps.
