able to spend at least 6 hours every day in the water but we had to 

 change the Baralyme and cook the meals and put certain pieces of gear 

 back together occasionally and it was just simply a matter of wanting 

 to spend more time on my primary objective and less time on the 

 housekeeping. 



I think we have had suggested this morning that there be a habitat 

 engineer on the next crew and I think this is a very good idea. How- 

 ever, I think he should be a diver and allow him to get out into the 

 environment because he is going to go stir crazy if he has to stay in all 

 the time. 



Mr. Downing. Thank you very much. 



Thank you, Mr. Chairman. 



Mr. Van Derwaubler. I wonder if I could add one word here. 



I think it is very important that in future development of under- 

 water equipment that the scientific communitj^ have the option or 

 ability to communicate with people who are doing this development 

 and suggest perhaps some of the things that we need. Particularly in 

 the military group I think that are developing equipment, and I would 

 think it would be helpful for us to communicate with them. 



Now, this may go on right now. I am not sure of it. But I know that 

 I haven't had the opportunity and I would like to. 



Thank you. 



Mr. Downing. I think you should be provided that opportunity. 



One final question. 



Was there any other equipment particularly unacceptable to you or 

 that you thought could have been improved ? 



Mr. Waller. I don't know that there was any other equipment that 

 was unacceptable. After having done this, we now have a much better 

 feel for what equipment we were lacking and I am afraid that some 

 of this equipment we were lacking has not even been developed yet. 

 We have a long list of things that are definitely needed. Other equip- 

 ment that we did not have was largely due to the fact that we could 

 not afford it at the time but some of it was available. 



Mr. Rogers. Would the gentleman yield ? 



I wonder if you could submit that list to the committee. 



Mr. Waller. Yes, sir. I would be delighted to. 



Mr. Rogers. I think this might be helpful. 



Thank you. 



(The information follows:) 



Equipment needs and. developmental items it considered to be necessary or 

 critical to future undersea habitat operations and conventional scientific diving : 



1. Extended duration (closed-circuit) underwater breathing equipment. 



2. Swimmer propulsiion units for transporting devices from place to place on 

 the seafloor. 



3. Diver heated suits to permit diver/soientists to conduct extended research 

 operations in colder waters. 



4. Underwater communieaitions and navigation equipment. 



5. Underwater echo-location equipment (sonar) for monitoring divers and 

 charting sample locations. 



6. A wide variety of environm.ental monitoring instruments for use by saturated 

 diver/Scientists. 



7. Additional work on development of decompression tables for saturated shal- 

 low water (100 feet) diving projects employing nitrogen as an enert gas instead 

 of the more expensive and problem ridden helium necessary for deeper diving.
