torn structure or form; (Z) an advanced positioning device or a 

 device to collect samples of water, marine plankton, marine fishes, 

 and the bottom including core samples for scientific purposes; 

 or (3) a device for observation and manipulation. Not included 

 are operational devices such as commercial fishing devices, 

 mining devices such as oil well drilling, and strictly military 

 equipment for detection, identification, classification, or des- 

 truction of military objectives. On the other hand, it is recog- 

 nized that there is a number of kinds of instruments which have 

 an indirect bearing at least on the collection of accurate, precise 

 oceanographic data. We will be pleased to consider these instru- 

 ments also. 



The primary objectives of this Symposium are to focus atten- 

 tion on oceanographic instrumentation and to inform representa- 

 tives of the industry of the United States about the known oceanog- 

 raphic instrumentation requirements of the operational and re- 

 search agencies. To fulfill the national objectives in this 

 accelerated oceanographic program, we need vast improvement 

 in instrumentation, at sea and in the laboratory. 



The presentations and discussions of the next two days are 

 unclassified. They reflect the r equirennents of Federal and non- 

 Federal activities in military and non-military applications. 

 They cover the needs for basic and applied research and for sur- 

 veys on research and ocean survey vessels. Discussions will 

 involve instruments to be used with ships underway and ships 

 stopped on station. The subject matter will cover a number of 

 disciplines including physical, chemical, and biological oceanog- 

 raphy, marine geology, geomagnetics, gravity, bathymetry, 

 radiobiology, special fisheries investigations, and others. You 

 have been invited because your companies have indicated an 

 interest and capability to develop and produce instruments of the 

 kind needed in the Nation's accelerated oceanographic program. 



During the Symposivim, we will indicate those areas where 

 the development and production of oceanographic instruments are 

 most needed and the extent to which the Government is prepared 

 to enter into cooperative agreements in developing and producing 

 thenn. Also, our purpose is to indicate the limitations imposed 

 on the development in this field in order that a proper balance 

 between all aspects of our oceanographic program are achieved 

 in view of available funds, manpower, and facilities.
