114 NATIONAL OCEANOGRAPHIC PROGRAM—1965 
and others will make it available. It is not of such a distribution or 
accuracy so that we can use it, so it all has to be evaluated on a case-by- 
case basis. 
Mr. Rogers. Would you let us have the list of companies contacted 
and those who have indicated willingness to cooperate, and those who. 
have indicated an unwillingness to cooperate ? 
Commander Nyeren. I do not think anybody has indicated an 
unwillingness to cooperate. They have put reservations in as to how 
their cooperation may be limited. 
Mr. Roerrs. I would think, then, you would indicate whatever diffi- 
culties might have arisen with the companies if you cannot use the 
material they have ? 
Commander Nyeren. Yes, sir. What percentage of the 16 I would 
be able to get this information from, is something I cannot answer. 
Mr. Rogers. I realize you would have to give this for the record as 
soon as that can be gathered. 
Commander Nyeren. Yes, sir.

INVESTIGATION OF GEOPHYSICAL Data HOLDINGS 
In January 1964, U.S. Navy and U.S.C. & G.S. representatives met to explore 
means of expanding the existing data exchange processes and improving com- 
munications with industry. Both agencies have worked with the Society of 
Hxploration Geophysicists in establishing contact. 
In November 1962, the Navy approached 26 geophysical and oil companies for 
available data. As a result, charts showing magnetic, gravity, seismic, and 
bathymetric information throughout the world have been received. Generally, 
all requests made by Navy have been honored. As a recent example of a special 
request fulfilled by industry, urgently needed gravity data have been supplied to 
the Navy to meet specific missile range requirements; in return Navy has ful- 
filled approximately 50 requests from industry for gravity, magnetic, and 
bathymetric data. 
Coast and Geodetic Survey has been concerned with the data holdings on the 
Continental Shelves of the United States. All regional and district offices have 
been directed to maintain liaison with geophysical and oil companies to de- 
termine their survey capability and the suitability and availability of bathy- 
metric and geophysical data. As requested by the committee, a list of individual 
and industrial firms with which C. & G.S. has been in contact to date follows: 
(1) Dr. Lynn S. Hoover: Recommended several individuals who had knowl- 
edge of geophysical data holdings. 
(2) Texaco, Mr. Martin Standard, New Orleans: Advised on methods and 
procedures for inspecting data. Discussed obtaining selected data, and explained 
some problems of datums, etc., that would make some of the data of lessened 
value for absolute purposes. 
(3) California Oil Co., Mr. George Jones: Discussed possibilities of obtaining 
gravity and magnetic data. No hydrographic data was available. 
(4) Shell Oil Co., Mr. Robert Dayton: Discussion at same time as that with 
Mr. Jones. 
(5) Committee for Cooperation With Governmental Agencies, Society of 
Exploration Geophysicists, Mr. F. Gilman Blake, Jr.: A meeting of the committee 
was attended. The existing data exchange arrangement with the Naval Oceano- 
graphic Office was explained by S.E.G. and a desire to extend this cooperation 
to CG. & G.S. was expressed. The C. & G.S. observer addressed the meeting and 
explained the C. & G.S. missions and requirements. In response to a question, 
the observer stated that ‘‘we had no desire to duplicate surveys in any geo- 
physical discipline on bathymetric operation, and that our appropriations were 
so limited that we would welcome knowledge of existing data which could be 
utilized in our programs and thus allow us to conserve funds” (R. A. Earle, 
November 6, 1963). Through personal contacts at this meeting several com- 
panies presented maps showing some of the gravity and magnetic coverage.
