Depth requirements and the design problems connected with 

 them are different for different types of service: (a) For the ship 

 of opportunity and the synoptic ship, oceanographic instrumenta- 

 tion will work at varying depths down to 2, 500 feet, (b) The sur- 

 vey vessel by comparison operates over a much deeper range 

 going generally to 4,000 fathoms. It is clear that winch size, 

 cable strength, and toughness of sensor housing are all related 

 to the depth factor. 



The onboard readout also varies for the kind of ship in use: 

 (a) Ships of opportunity which work on a worldwide basis will have 

 a punched tape type readout from their sensors. These tapes will 

 be mailed in to the NODC for normal processing or will use dis- 

 patches for priority messages, (b) The synoptic ship might be com- 

 pared to rapid handling requirements of Weather Bureau data 

 collections. Oceanographic data received on board will utilize 

 radio telemetry, forwarding information to the Task Force Cominan- 

 der and to shore-based plotting centers in order to expedite ocea- 

 nographic synoptic charting, (c) The survey vessel would, of 

 course, have the most modern data handling and processing tech- 

 niques which would include computer facilities onboard. Telemetry 

 of oceanographic data might be a requirement in some instances. 



I would like to point to one bright spot in the overall instru- 

 mentation program. It is the submarine instrumentation suit which 

 we have on display here today (fig. 8. 6). This suit approaches 

 what we are looking for in the way of modern sensors and automatic 

 data processing. Admittedly, there are only a few variables in- 

 volved, but this approach and this system of rapid data handling 

 is a big step forward and indicates that we are on the right track 

 in ovir general approach to other types of platforms. 



By way of summary I know that all of you are interested in 

 the practical aspects of hardware production and specifically the 

 numbers and value of these individual instruments and instrument 

 systenns. 



Figures on the Navy's planned "Ten Years of Oceanography" 

 program have been published earlier. We have coupled these esti- 

 mates with the presently known plans of other government agencies 

 ajid have summarized requirements as follows. I cannot empha- 

 size too strongly the planning natvire of these figures and the lack 

 of sufficient data to make more reliable estimates. Allowing for
