386. NAVAL AIR DEVELOPMENT CENTER: NADC 



NADC is the Navy's principal activity for research, development, 

 test, and evaluation of naval aircraft systems. Ocean surveillance 

 is an important function of the Center. Its efforts concentrate on 

 measurements of ambient noise intensity, directionality, and propaga- 

 tion loss under variable environments. 



387. NAVAL COASTAL SYSTEMS LABORATORY: NCSL 



Formerly the Navy Mine Defense Laboratory (NMDL) , NCSL special- 

 izes in shallow-water oceanography, waves, and estuaries, and their 

 protection. 



388. NAVAL ELECTRONIC SYSTEMS COMMAND: NESC 



NESC maintains an acoustic data file and a file of marine 

 environmental data. 



389. NAVAL ENVIRONMENTAL SUPPORT OFFICE: NESO 



NESO is the overall program coordinator for the Naval Environ- 

 mental Protection Support Service (NEPSS), the central environmental 

 information center for the Department. NEPSS maintains the Navy 

 Environmental Protection Data Base (NEPDB), established in 1973 to 

 support all levels of Navy commands with environmental quality infor- 

 mation. A newsletter Clean Slate provides up-to-date information 

 about the Program. 



390. NAVAL OCEAN SYSTEMS CENTER: NOSC 



NOSC is the principal research, development, technology, and 

 engineering center in the Department of the Navy for undersea sur- 

 veillance, ocean technology, and advanced undersea weapons system. 

 It was formed in 1977 by a merger of the Naval Undersea Center (NUC) 

 and the Naval Electronics Laboratory Center (NEL or NELC). NUC was 

 established as a major command in 1967 and succeeded to the functions 

 of the former Naval Undersea Warfare Center (NUWC). NUWC had been 

 formed earlier in the 1960's by a merger of the Naval Undersea Re- 

 search and Development Center (NURDC) with that part of the Naval 

 Ordnance Test Station (NOTS) at Pasadena, Calif. NUC was responsible 

 for the development of the Remote Unmanned Work System (RUWS), an 

 underwater vehicle for use in deep waters. 



NEL or NELC was formerly known as the Naval Command Control and 

 Communications Laboratory until its name was shortened to the Naval 

 Electronics Laboratory Center. 



NOSC's Arctic Submarine Laboratory (ASL) was responsible for the 

 Marginal Sea Ice Zone Pacific (MIZPAC) program of studies of acoustic 

 and related oceanographic peculiarities of the marginal sea ice zone 

 in the Pacific Arctic. The Applied Physics Laboratory of the Univer- 

 sity of Washington (UW/APL) carried out the program in 1971-74. 

 NOSC sponsors a Marine Environmental Management Office (MEMO) that 

 makes biological surveys in important Navy harbors, particularly 

 those in the Northeast Pacific area. It is responsible for Mobile 

 Sonar Technology (MOST) and sponsors a MOST Technical Document In- 

 formation System (MOST/TDIS). It also is responsible for the Navy 

 Ocean Experimental Acoustic Data Bank (NAVDAB). 



391. NAVAL OCEANOGRAPHY COMMAND: OCEANAV 



Established in 1978 with the disestablishment of the Office of 

 the Oceanographer of the Navy, also referred to as OCEANAV, the newly 

 established command is responsible for oceanographic and meteorologi- 

 cal activities of the Department of the Navy and includes the Naval 

 Oceanographic Office (NAVOCEANO); the Fleet Numerical Oceanographic
