return to the Philippines for the remainder of the year. The USNS 

 Harkness, involved in coastal surveys of Greece during FY '73, is 

 continuing the effort through FY '74. 



Center-of-mass coordinates were determined for five stations in 

 Iceland for readjustment of that country's geodetic net as a part of a 

 joint U.S. -Iceland project. Extensive geodetic operations were 

 carried out in the Eastern Mediterranean, the Philippines, and Korea 

 in support of coastal hydrographic surveys. An astronomic-geodetic 

 survey was conducted in Italy and Sardinia in response to fleet 

 requirements, and geodetic surveys were conducted for a number of 

 Navy commands. In FY '74 to date, additional geodetic surveys have 

 been completed, and geosciences stations have been established in 

 the Alaskan Naval Petroleum Reserve, the continental United 

 States, the Indian Ocean, and the Western Pacific. Plans call for 

 additional surveys in the United States, Thailand, Spain, Greece, 

 and the Western Pacific and North Atlantic areas. The astronomic- 

 geodetic survey started in Sardinia will be completed by the end of 

 FY '74. 



Oceanographic surveys are conducted from three survey vessels, 

 three ocean research laboratory pool ships, and two new specially 

 equipped P3-A aircraft. In FY '73, the anti-submarine and undersea 

 warfare (ASW/USW) programs of the Navy were supported by 

 MAGNET aircraft surveys and by the USNS Kane, Bent, and Wilkes 

 with acoustic surveys in the North Atlantic, the Caribbean Sea, the 

 North Pacific, and the Bering Sea. Bathymetric data from these 

 surveys are processed and delivered to the DOD bathymetric library. 

 Geophysical data are delivered to the National Geophysical and 

 Solar Terrestrial Data Center. In addition, summer and winter 

 oceanographic survey operations were carried out in two west 

 Pacific straits, aboard fleet-assigned ships, and acoustic ambient 

 noise and reverberation data were collected from a P-3 

 oceanographic aircraft in the North Atlantic. In January 1973, the 

 computer-oriented Oceanographic Data Acquisition System 

 (ODAS) was installed in the USNS Wilkes; all three survey ships are 

 now equipped with ODAS. In FY '74 to date, the WiJkes and Kane 

 completed ASW/USW surveys in the North Atlantic and 

 participated in an experimental cruise to isolate problems in low- 

 frequency acoustic measurement techniques. The Bent continues 

 special operations in the North Pacific. Airborne survey techniques, 

 developed to measure acoustic bottom loss, became operational. 



In FY '73 NAVOCEANO continued to provide technical 

 coordination and oceanographic support of research operations 

 aboard three Navy oceanographic research pool ships, USNS Lynch 

 in the Atlantic and USNS Desteiguer and Bartlett in the Pacific. In 

 the Atlantic 3 laboratories were accommodated on 7 cruises with 241
