NATIONAL OCEANOGRAPHIC PROGRAM—1965 115 
The speech prepared for presentation is attached. Mr. Blake was furnished 
copies of a letter explaining the position and requirements of Cc. & G.S. and 
copies of the minimum standards of accuracy for hydrographic surveys. These 
were distributed by him to potential data holders in order that each might 
analyze his own data for possible use by C. & G.S. and communicate this to 
C. & G.S. 
(6) Tidelands Exploration Co.: Offered to sell hydrographic data from their 
files. These data were in an area for which C. & G.S. surveys were considered 
to be adequate. An examination disclosed that their geographic distribution 
was such as to make them of insufficient value to justify purchasing. 
(7) Capt. Paul S. Bauer: Discussed availability of oil exploration data in 
Gulf of Mexico and its utilization by C. & G.S. This was one subject among 
others concerning charging activities. 
(8) United Geophysical Co., Mr. Walter Mitchell: C. & G.S. requested a meet- 
ing at a future date to discuss data holdings. 
(9) Geotechnics & Resources, Inc., Mr. William H. Atwood: C.&G.S. explained 
the contract between the California Co. (representing several oil companies) and 
the Government for extending the basic horizontal survey station network of 
the United States through the offshore oilfields. Discussed reasons for the 
eontract and benefits to accrue to the Government and the oil companies, and 
the exploration firms. 
(10) Seismograph Service Corp., Mr. H. Curtin: General discussion of services 
and equipment the company could and would furnish. 
(11) Aero Service Corp., Mr. Homer Jensen: A visit was made to the 
Philadelphia office of Aero Service. Data holdings were examined and discussed. 
The amount and type of data that can be released was made known and will 
possibly be utilized in the world magnetic charts. 
(12) Gulf Research & Development Co., Pittsburgh: Gulf briefly outlined 
magnetie data holdings available. 
(13) Operations Research Inc., Harvey D. Kushner: After being offered as- 
sistance of the Society of Exploration Geophysicists and ORI sent them two 
questionnaires. Their replies will be considered and included in the reports 
ORI will make to C. & G.S. and ICO under their ocean survey plan contract. 
(14) Jersey Production Research Co., Mr. K. H. Burns: Mr. Burns expressed 
a desire to cooperate with the C. & G.S. and referred our request to Humble Oil 
& Refining, their domestic operating affiliate. 
(15) The California Co., Mr. J. A. Harris: Mr. Harris reported on availability 
of data in his files. This reconnaissance data was inspected by the New Orleans 
district offices. 
(16) Standard Oil Co. of Texas, Mr. E. J. Smith, Jr.: Mr. Smith invited a 
representative to discuss their data holdings. 
(17) Offshore Raydist, Inc., Mr. G. A. Roussel: Company was requested to 
furnish information on distribution, equipment, and costs of their services in 
the Sabine Pass area. Future discussions will be held. 
(18) Sidney Schafer & Associates, Mr. Schafer: Holdings of gravity data for 
the Gulf of Mexico region were described by M. Schafer. Detailed surveys would 
not be released, but some of the data might. An index of holdings and a copy 
of the specifications were obtained. No magnetic data was held. 
(19) Lorae Service Corp., Mr. H. W. Hutchison: Lorac furnished details of 
their existing services and costs for offshore survey work. C. & G.S. replied that 
e would contact the company to negotiate agreements if the need arose in the 
ture. 
The analyses of data holdings and company capabilities will be continued. 
To date, several conclusions are becoming apparent. 
Some of the companies state that they can make surveys to C. & G.S. spe 
cifications. This has not been confirmed because the exploration surveys on 
which they have been engaged are not to these standards, and need not be for 
geophysical purposes. 
The available data holdings represent a valuable source of some types of 
information. In every case, the data must be examined for accuracy and dis- 
tribution. Some of the reasons why data examined was not adequate or 
available follow: 
_ (1) Data are of a proprietary nature, procured under contracts which pro- 
hibit its release. 
(2) Values of gravity and magnetics are not based on a standard datum.
